a demon appeared. Um, something that looked like a monster. And I thought to myself, okay, that's strange. It's all in your head. It's all in your head. This must be some kind of projection from your subconscious. That's what this must be. This demonic entity started literally attacking me. Like full-on attacking me. And I've never experienced anything like this. It's probably a manifestation of your subconscious, you know? And like there's talk of this kind of thing. It's called bruharia. It's witchcraft in the Amazon. This couldn't just be that this is shamanic warfare. There there's no way, right? Like cuz that can't be real because it's not real. And that was my logic. It can't be real because it's it's not real. We don't have a scientific explanation for what this is. I went and spoke to the quantero. Um and his response just changed my life forever. And he just said, "Dr. Simon Ruffle is a clinical psychiatrist who walked away from the NHS frustrated because his patients weren't getting any better. He flew to the Peruvian Amazon to study why an Amazonian brew was curing conditions that his profession couldn't touch. He ended up running the first ever study on psychedelics and epigenetics. He found that Iaska may literally rewite trauma at the genetic level and started training as a Shapibo shaman. He now holds both a membership of the Royal College of Psychiatrists and an apprenticeship under a Peruvian Iawaska shaman attempting to marry elements from both traditions for the absolute best mental health outcomes. Subscribe to uncover whether DMTLs file noise complaints when too many people visit at once. >> Over the next 3 days, I experienced the most crippling anxiety I've ever experienced. It was incredible. I could I couldn't leave my hut to speak to people. I was a shadow of myself. My posture had changed. I was suddenly hunched over. I had these terrifying nightmares, these like horrendous nightmares. I was like, "What is happening?" Like, "What on earth is going on?" And then 3 days later, he came back and he found me. And he was like, "Okay, we're going back into ceremony. I'm going to remove remove this curse that you have on you basically." And by this point, I was terrified cuz I spent 3 days just contemplating like my perception of reality, contemplating what is mental health? How could I suddenly just have crippling anxiety when I just did not have anything like that before? And I went back into ceremony. I drank the Alawaska. He sang aos, which are these um shamanic chants in Shapibo. And it was incredible. I could feel these almost like three suckers almost like the kind of thing that you stick your mobile phone to your car windscreen. um uh with I could just feel them just three of them just pop off me and all of the the demonic things that I was seeing in the ceremony suddenly just completely disappeared and it was back to these bright beautiful colors that I always had seen with >> I thought med school and PhDs were hard like that's nothing compared to training and sharpness is it completely blows it out of the Simon Ruffle, what is Shapibo Curanderismo? >> I'm so glad you asked. Um, Shabibo Corduranderismo. So, curanderismo is a word that can be usefully used to describe shamanism. You know, more or less. Shamanism as a word actually doesn't really mean that much. Um, it loosely kind of fits one group of traditional healers from Siberia, but it's almost been adopted as this uh this word to describe anyone who enters the world of the spirits in a nutshell. You know, most people in the western world understand if you say, you know, shaman, they have an idea of what that of what that might mean. And the Shapibo are a particular group of people based in the Peruvian Amazon who work with a psychedelic brew called Iawaska. And they are corderos or corderas. So they are shamans. And so they use this psychedelic brew in a ceremonial ritual. And they they use it to heal and to treat many of the conditions that we treat here in the west. But they have a very different explanation and understanding surrounding how it works. >> Beautiful. really well explained. Let's walk through. I want the listener and me to understand the most important context in your life that led you to interacting with the Shabiba. What What do we need to understand about your prior life that led you to the Peruvian rainforest? >> It's a good question and I get asked that a lot perhaps unsurprisingly. Um so I'm a psychiatrist by background. um and I was working in the NHS and for many years I went to medical school specialized in psychiatry. The only reason that I went to medical school was because I wanted to do psychiatry because I was fascinated with everything to do with the human mind. Fascinated by people. I was fascinated by the theory behind it. I was fascinated by you know what happens when it goes wrong in quotation marks. Like what is that? You know what is psychosis? What is it when people kind of lose connection with their their sense of reality? And it was all great and I and I got through med school and I specialized in psychiatry and started, you know, working on the wards and there was only one kind of major issue with it was which was that the vast majority of patients didn't actually get that much better. And it's not a controversial thing to say that. You know, most psychiatrists say that quite openly. In medicine, psychiatry has the reputation of being the Cinderella specialty. That's what most people refer to it as. And that's mainly because we haven't seen huge breakthroughs in psychiatry for over 50 years. We use many of the same treatments that we were using 50 years ago. We don't use uh terms like treat um or cure. Um and we end up treating it almost like a paliotative specialty. And so I was working as a disgruntled psychiatrist in the NHS. And I was beginning to think, okay, what am I going to do um with the rest of my life? Is this really everything that I spent the last 12 years or so working towards? And so I decided to take a bit of a break from working in psychiatry. Um, and by a stroke of of luck, I found myself sitting next to somebody who was training to be a cord or training to be a shaman um in the Peruvian Amazon. And he was training with this group of people called the Shapibo. And we were roughly the same age and kind of equivalent grades. you don't really have grades in ship calledismol but you know about the same level of training and the different kinds of medicine and he started telling me that he was treating conditions like depression PTSD anxiety OCD uh and he was using the word cure yes we cure them you know they're treated they're completely fine and then they go back home and then that's the end of that and I couldn't believe it and I thought you know what is this guy talking about there's there's no way there's no way and the more that he started telling me about it the thing that really kind of piqued my curiosity was that he wasn't denying that Iawaska worked in the way that we know most psychedelics work interacting with the uh you know the serotonin receptor um largely causing neuroplasticity all of these kinds of things but he was saying to me yeah yeah yeah I'm sure all of that stuff is happening but actually the way that we're treating conditions in the Peruvian Amazon is by calling in spirits and spirits are treating patients on behalf of these shamans. And that's the way that shamanism works more or less in a very summarized version. And I I was just thinking this I can't believe I'm hearing this. There's no way that anyone actually believes this, right? Like there's that that couldn't possibly be true. So he invited me to uh to come down to the Peruvian Amazon um with him to see what he was doing. I had my first experience with Iawaska. Um this was 2015 and for 4 years I went back and forwards to the proven Amazon just doing research into Iawaska. I ended up doing a PhD looking at Iwaska uh and mental health outcomes and then after four years of going back and forwards I actually started training in so training to become a shaman. So I'm trained in western medicine research psychology and Amazonian shamanism. And that's the the yeah, that's where I sit today at that kind of intersection of those three worlds. >> Incredible. So so well explained and what an interesting backstory. I mean, life really does send you in a random direction when you're standing you're sitting beside a shaman and you end up in a random conversation you never would expect. >> Totally. >> And for some reason you say yes and see how deep the rabbit hole goes. Yeah. When you say spirits, maybe it's a good idea to give some idea of what that word means because it's one of those things that can be 20 different ideas, definitions, models could pop to mind when you say spirits. What do the shapibbo mean when they say spirits? >> That is actually an excellent question. And the word spirit is absolutely loaded with connotations with associations within the English language. part of the training in Shapibo, you have to learn shapibbo so that you can sing shapibbo in ceremony. That's um that's the way that the ceremonies work and there isn't a direct translation for spirit. It's more akin to some kind of energy, but again energy is extremely loaded. You know, people have such kind of like and this is of me kind of 15 years ago. If anyone said energy, I'd roll my eyes. Unless they're physi physicists, they be like, "What? You don't know anything about energy? What are you talking about?" Um, but it's something more akin to that, some kind of energy. Probably a closer translation would be heirs, like the heirs of certain entities that we can't see and but it's a very difficult thing to describe. Do you want to detail your first experience? I'd love to go through, you know, exactly what the process is, how they makea in the Peruvian rainforest. We can go into what happens in the brain. I want to know about the ceremony, but maybe I want to start if it's okay with you with your personal experience and why it was so impactful on you that it sent you on the trajectory that you're on now. >> Yeah, for sure. I mean, the first thing to say is that the the first experience I had with Iawaska, people often say the first thing it must have really like changed your life being this overwhelming experience. It actually wasn't. It actually wasn't. So I drank Iawaska for the first time and uh I was on a I was on a retreat. I was drinking uh six times in two weeks every other day which is a normal way that western isers engage with Iawaska. You wouldn't really do that if you were indigenous to the population. It's a a kind of akin to going to a western hospital and saying, "Yeah, I'd like to have all of the treatments I can have in two weeks. Give me all the antibiotics. Want a CT scan, MRI?" You know, you just you wouldn't do that. But it's kind of how westerners engage with Iaska. And I uh so I went went to Peru in my first experience. Um I had a few really interesting things that happened in those first two weeks. So for example, I was shown two different versions of myself. I was shown a version of myself which was the version that I currently was. um the version that had experienced various trauma uh you know various like negative things that happened to me as has happened to all of us you know I'm not talking about anything out of the ordinary here I'm just talking about you know being human you know and being on this earth the are kind of things that we all experience and I was shown how the maladaptive coping mechanisms that I had experienced um were influencing my life and impacting my life mainly in a negative way and then I was shown a different version of myself which was that version that wasn't dominated by those maladaptive coping mechanisms and who I could be if I stepped away from those own those old patterns um those old patterns of being and then I went back to uh I went back to London I was based at King's College London at the time working as just a mainstream psychiatrist um and I started conducting research into the effects of Iawaska initially on personality then started looking at common mental health conditions. Then conducted the first ever study uh looking at Iawaska on epigenetic change and we'll go into that in in a bit more detail a bit later. And that formed the backbone of my PhD. Um, and the more that I was going back and forward into the Amazon rainforest, I was having quite an interesting experience of these dialogues between the two worlds and I would so I would be in the Amazon rainforest and the Cordero who I later started apprenticing under, Don Rono Lopez, um, would say things to me like, "Simon, there are these entities, there are these spirits that are trying to communicate with you in ceremony. You need to start listening rather than just ignoring them." And I would respond by saying, "Well, actually, Don Rono, I think you're fine." So, the brain is an expert in predicting things and we see faces quite a lot. So, that's why I keep seeing these faces, you know, in ceremonies because we're designed to do this as humans. Um, and so I have, you know, a neuroscientific explanation as to as to why this is happening. Thank you very much. And he would just laugh at me. He would just like see you and maybe and what he would literally say is maybe you're just ignoring what's happening right in front of your face. And I was kind of the uh yeah for the Shapibo community I was the the scientist who wouldn't listen. And then I would go back to King's College London and I would be speaking to you know my psychiatric colleagues and I would say do you think there's any chance that what they're talking about in the jungle could have some kind of validity? you know, people are talking about these spirits and entities and we just say there's no way. We don't have anything that could explain that other really than, you know, psychosis, you know, delusional beliefs. And uh and my psychiatric colleagues would look at me and say, "Simon, I think you're spending too much time in the jungle, you know, and too much time just drinking in the jungle." I was like, "Okay, in both of these situations, I'm kind of the the odd one out here." Um, and then after after four years of going back and forward to the jungle, I uh I had an experience which I can talk about if you if you want to. It's it's quite gnarly. Uh, which completely shattered my perception of reality. And I ended up training in people as well. Um, and honestly, it was the best thing I've ever done. The hardest thing I've ever done. I thought med school and PhDs were hard. Like that's nothing compared to training and sharpism. is it completely blows it out of the water. >> Incredible. So much so much to so many questions there. I'm I'm curious before we dive into the experience, was anything different on the leadup to that to that to that particular trip that had such a different reaction to the others? Was do did you feel like this one was going to be special? Was there anything different that was happening on the leadup? Did you, you know, was there just anything that you could have predicted that this was going to be the one that was going to obliterate everything and change how I think about it, or was it just you thought this was going to be like all the other ones? You didn't make any predictions ahead of time? >> Mhm. Yeah. I I thought this was going to be exactly the same as every other ceremony I'd had. And you know, by this point, I drank many times. I've been going back and forward to the jungle for four years. So, you know, I was I drunk it about 80 times, I think, you know, at this point. And um so I wasn't new like I wasn't new to this you know I was kind of experienced in what to expect and but um yeah so basically what happened is I I was in my my room in my hut and I I remember actually I was reading a paper on DMT on my laptop like before going into the ceremony and that meant that I was late for the ceremony and they usually do this smoke protection before you come into ceremony it's this particular type of plant um used in in shanic traditions called mapacho. And I remember thinking I'm going to miss that protection, but you know, it was just smoke, right? Like surely it can't matter that much. And then I got to the ceremony, went into the ceremony, drank a cup of Iaska, and I went and I sat down on my mat like I did, you know, before um the ceremony started, like 80 times before. And this time was different. And what happened was seemingly out of nowhere, as soon as I started to experience the kind of the subjective effects of Iawaska, a for a better sense of the word, a demon appeared. Um, something that looked like a monster. Um, and I thought to myself, okay, that's strange. It's all in your head. It's all in your head. You know, this is like, you're fine. You can deal with this. This must be some kind of um projection from your subconscious. That's what this must be. And this this demonic entity started literally attacking me. Like full-on attacking me. And I've never experienced anything like this. At this point, I've actually experienced this quite a lot now, but at that point, I'd never experienced anything like it. And it was bringing up all of these insecurities. It was taunting me. It was going into the the depths of my childhood and my being and dredging up all of these things about myself, showing them to me and just annihilating me. And it I ended up falling off my mat. I fell onto the floor of the maloa, which is the ceremonial space, the structure that you drink in in the Shapibo tradition. Uh I could barely breathe. I was really struggling to breathe. Um I had Iaska pouring out of my mouth. Um, and I was under my breath trying to scream like, "Help me." Like, "Help me." But nobody could could hear uh what I was saying, so I could barely get anything out. And during that experience, it's it's so hard to describe what that was like, but it was so real and so different from anything else that I'd experienced that in that moment, I was I was convinced that was something different, that that was something else. And I was there conducting research, the epigenetic study um with a psychologist, you know, one of my best mates. And after the ceremony, um finally in the ceremony, somebody noticed, the cordero noticed, they came over, they sorted me out and kind of got me sitting back up again. And the ceremony finished and I went and I spoke to my colleague who's a psychologist and I told him what had happened and I said look I know this sounds completely bizarre but I'm I'm almost certain that I just I just got attacked. I just got attacked. I just have no idea what that was. Like what on earth? And he said what I would have said 4 hours earlier which was ah yeah don't worry about it. It's probably a manifestation of your subconscious you know and like there's talk of this kind of thing. It's called bruharia. There's witchcraft in the Amazon. Perhaps it was just that you heard someone say that and it came up. It's a fear of yours. So, it came to the surface. And I was just saying, "This is I I get it. I I get it. Logically, I get this. I understand what you're saying, but I I swear this was something different." And then, so I I went and spoke to the quantero um and his response just changed my life forever. and he just said, "Ah, yep, yep, yep. Really sorry about that. You you did get attacked. So, I was trying to fight that all all night. What happened is I'm in a shamanic battle. I'm in a fuse with another cord and because you've been coming back here for 4 years, he thinks that you're my apprentice. Um, so when he couldn't get to me, he just attacked you. Um, try not to worry about it. So, sorry. I'll sort this out over the next few days. You just got caught in this crossfire basically." And so I was I was just left thinking what like what on earth is happening? My perspective of reality was being shattered like at that moment and I was trying to explain it through my psychiatric training, you know, through my training and my PhD. You know, there must be a way of understanding this. This couldn't just be that this is shamanic warfare. There's no way, right? Like cuz that can't be real because it's not real. And that was my logic. It can't be real because it's it's not real. We don't have a scientific explanation for what this is. And so over the next 3 days, cuz he was going to be um back back in the village to um to help me in 3 days time, I experienced the most crippling anxiety I've ever experienced. It was incredible. I could I couldn't leave my hut to speak to people. I was a shadow of myself. my the way that I held myself, my posture had changed. I was suddenly hunched over. Um, and when I went to sleep, I had these terrifying nightmares, these like horrendous nightmares. And I was like, what is happening? Like, what on earth is going on? And then 3 days later, he came back and he found me. Um, and he was like, "Okay, we're going back into ceremony. I'm going to remove remove this curse that you have on you, basically." And by this point, I was terrified because I spent three days just contemplating like my perception of reality, contemplating what is mental health. How could I suddenly just have crippling anxiety when I just did not have anything like that before? And I went back into ceremony. I drank the Iawaska and he came up and he sang aos, which are these um shamanic chants in shapibbo. And it was incredible. I could feel these almost like three suckers almost like the kind of thing that you stick your mobile phone to your car windscreen um uh with. I could just feel them just three of them just pop off me and all of the the demonic things that I was seeing in the ceremony suddenly just completely disappeared and it was back to these bright beautiful colors that I always had seen with skin. And so the the ceremony finished and so I went up to the cordo was just oh my god I thank you so much like thank you so much and he just it's nothing it's nothing it's nothing that's just like a tiny tiny curse like it's so easy so easy curse >> yeah just a tiny tiny curse like honestly like don't worry about it it's like nothing and I was just I was so blown away I was like what earth like there's no way that that could be real like how like what is real. And at this point I was conducting yeah the first ever study looking at um any psychedelic and epigenetics which is obviously like genetics is like that's like hardcore science but during that study I actually started training in shamanism and two weeks afterwards I was like I have to know I have to know what this is I have to understand what that is and I genuinely feel that as a scientist you can't experience something like that a potential like at least in my mind like blind spot in science and not begin to investigate it further. Of course, with respect, you know, doing it ethically. And so I asked for permission to start training with this cordo. And he said yes. And so, ironically, I did become his apprentice after that other cordo, what I now believe, you know, attacked me. And then I went back to to the UK again, went back to King's College London to continue working as a mainstream psychiatrist with this new idea, this new perception of what mental health and to be honest, reality could be. Uh, and that was, you know, 11 years ago. uh and I've spent the rest of uh my time, the rest of my career trying to marry those two worlds of western science and indigenous science, finding out where they work together and where they don't work together uh and trying to come to a more coherent understanding of the nature of reality and the nature of mental health as well. >> Wow, man. Holy [ __ ] Thank you. Thank you for sharing that first off because I know that's a vulnerable experience and and so intense and you know I've had some negative experiences on psychedelics and I know that every time I really open up about it it's it's vulnerable and it's difficult. So thank you for sharing that. I mean that's completely insane. I mean that is is so crazy. >> Yeah. I have so many questions and it's interesting because I clearly have my science hat and the reason I wanted to talk to you is because I wanted to really understand where that spiritual hat comes into the equation like how does that add to the science how do those pictures come together and I know this is a very big question so we can attack we can kind of tackle it in parts if you like but now a decade on from that experience how do you think about how western psychedelic movement and the current, you know, psychedelic renaissance that we're on at the moment where things are are freeing up a little bit. There's more research being done. There's there's more scientists being funded, which is great. Obviously, Trump had that executive order that is hopefully going to have an effect on psychedelic research and open things up a little bit. What can that perspective and that movement learn from the centuries old practice of shamanism in the rainforest? And again, hell of a question. So sort of tackle that from any angle you want to start, but I'm curious, you know, a decade on like what have you learned about how those perspectives can work together? >> Yeah, I mean it's a big question for sure. Um and there are many there are many things there are many ways um that people try to marry these worlds. Obviously, there are huge ethical implications uh surrounding um the use of psychedelics and potentially uh you know extracting them from indigenous communities. But the thing that that I'm most interested in um is safety and efficacy um with the use of psychedelics. And so I'm a clinician like by backgrounds like first and foremost I'm a clinician and but I don't work in clinical psychiatry anymore and I have big concerns about the so-called psychedelic renaissance and that's largely due to issues with safety and efficacy. So let me explain this with uh with some anecdotes. So when I've been speaking to um the cordenderos that I apprentice with in the Amazon rainforest and I've been telling them about the clinical trials that we've been doing here in the western world the response is always quite interesting. So initially most of them have said to me ah you know that's fantastic that's fantastic that you know quite often the indigenous peoples refer to us as little brother they're big brother we're little brother because we're kind of naive and stupid which again is ironic because our narrative quite often at least throughout history has been the other way around >> right >> um so they often say okay that's great that little brother is so interested in in our medicines in psychedelic medicines and also our own medicines like psilocybin which you know grow in Europe And then they say, "So, how are you using it? How are you doing it? Who who do you have who's who's trained in shamanism to work with energy? Who do you have who's there to remove a demon that's is stuck to these things stuck to these people? What protection are you putting up to protect the people that are giving the psychedelics?" And I just say, "Well, you know, we don't really kind of think in terms like that. We don't really, you know, have words and language to describe those things. We normally have a psychiatrist and a psychologist um in a dosing room. Um to be honest, you're lucky if you get that now. Actually, it's moving further and further away from from having that kind of setup in the diet. Um yeah, and so we we talk to the patient, you know, we talk to them before and after they take psychedelics usually. And then the coordinator will say, "Yes, yes, yes, yes, I get that. But but what do you do if somebody needs an exorcism?" Well, you know, I mean, we don't really think of it in in terms of of exorcism. you can't really kind of like bring that language into, you know, randomized control trials. >> And their response has been, well, that's just incredibly dangerous. I can't believe you would do that. That's so dangerous. You're literally opening up the participant. They refer to it as the energetic body. You're opening up the participant's energetic body. And anything can come in. Anything can come in. If you're doing it in a hospital, that's probably the worst place that you could be doing it. And what about the the practitioner? What about the the therapist? You're setting up like an energetic highway between the participant and the therapist. They're going to get covered in, you know, bad energy from these participants. That's so dangerous. I can't believe you would do that. You need to change the way that you're doing it because it's extremely unethical to approach it in that way. And then I have very similar conversations but the complete opposite with people from a western scientific background where you know when I work with other researchers fortunately now more and more people are getting more open to this you know kind of observational research in the Amsterdam rainforest but especially when I was beginning people would say like some of my professors even would say wait so how far away is this um the Iaska retreat center from the nearest hospital? I said, "Well, it's one day by boat." Like, "Right." Okay. And one day by boat. Yeah. By by canoe. Like, >> what an answer. Oh my god. >> I know. Yeah. One day by boat. Yeah. It depends on the rain. And you're like, "All right. Okay. >> Depends on the crocodile feel." >> Exact. Exactly. >> Yeah. And then, oh, and do you have any medical professionals there? I mean like well you know I'm there but you know when I'm not there then no there there's no one there and they say the exact same thing. They say oh my god that's so unethical that's so dangerous. No it absolutely needs to be in hospital. And so it's just this this clash of these different paradigms. But I do think that there is a way that we can work together and I'm pleased to say that the beginnings of that is starting now. There are the beginnings of traditional healers, traditional shamans if you will, working with scientists and psychologists to try and figure out the most effective way to work with psychedelics. But it's extremely difficult for a number of reasons. Of course, these are two completely different paradigms that in most people's eyes just clash and they don't work together. Um, but also because of historical ethical reasons. you know, the science has an awful track history when it comes to working with indigenous peoples. And so, quite understandably, they kind of they're thinking, well, what's in it for us? How do we know they're not going to just extract all of our medicines again? How do we know that they're not just going to steal our ideas and use it to make profit? So, it's it takes a lot of time. It takes building and weaving these relationships between these two worlds. >> Yes. If you want to truly understand the contents of your own inner conscious experience, like your mental imagery, your own inner speech, or your emotions, then click the link in the description and take my 7-day inner experience challenge. Throughout the challenge, you will learn about the five frequent phenomena that make up our conscious reality and engage in the actual process used in research to discover your own completely unique breakdown. How often do you really inner speak? What kind of mental imagery do you have? Do you see in vivid pictures, in three dimensions, in two dimensions, black or white? Maybe you're part of the 5% of people among us that have no mental imagery at all. Where do you feel and process your emotions? We all have fascinatingly different answers to these questions. And by day seven, you'll finally be able to confidently answer these questions for yourself. It is completely free to do and you will get the most comprehensive breakdown of your actual conscious reality using only research proven methods. I am genuinely so excited about this. Just click the link in the description. I hope to see you inside the community. Do you have an example of maybe something that if you said to yourself 11 years ago, you would be very dismissive of the some spiritual or shamanistic idea that you believe now where you know past you would have said that's ridiculous. You know that that's that's not science. Something where you've really changed your tone from being very scienceheavy to okay maybe there is a spiritualism shamanistic side to this. You know, you mentioned at the start during your bad experience, the demon experience that you missed the protection smoke, right? You know, you highlighted that as an important point and that would be maybe a point where the the science hash is saying, well, come on, that's, you know, there's nothing to that, >> but then, you know, is that a perspective that you've shifted on? You know, I'm curious like really how your mindset has changed on this over over your time and especially going through the apprenticeship in the shamanism and everything. Like do you have a really good example for people on on something you've changed your mind on? >> I mean there are there are so many there are so many examples. I mean I think one one obvious one would be a shift more towards an animistic view of the world. >> Okay. So a lot of shamanism is based on the worldview of animism. And animism is the idea that everything has a spirit. Everything has consciousness like if you will that that's one way of of explaining it. And that means that when you engage with pretty much anything um you engage with it uh in uh in a different way. So let me give you an example in terms of Iawaska. So if you believe that iawaska and your perception is that iawaska is in some way conscious then when you when you drink Iawaska you're no longer thinking ah yeah there there's just DMT binding to my serotonin receptors my oxidase inhibitors preventing it breakdown you know within within the stomach etc etc etc you're now thinking okay this is this is a spirit and I treat it in the way that I would treat any kind of relationship I want to get to know this spirit. I want to get to know this this being and form a relationship with them. And so it means that when so for me when I conduct research, I'm no longer conducting research on Iawaska as it were. I'm trying to conduct research with Iawaska almost as a a co-ressearcher in that process. And that's something that I've been learning with the indigenous corderos and that I work with. And it's something that um that that really asks you to change the way that you approach research. Um which is where the fun really starts. And what how does that change the trip itself? How that that sort of shift in psychological relationship with the substance? How does that manifest experientially once you take the IASA? >> I mean for me personally is through communication. Through communication and intention. So you're no longer there kind of talking to yourself or watching your subconscious material kind of manifest in some way in front of your eyes, but instead you're you're asking things. You're speaking. you're in dialogue. It's uh it's an alive open conversation. Um and you have to be willing to hear yes and you have to be willing to hear no. It's quite difficult to describe. It's something akin to prayer. Again, prayer is an extremely loaded word. Um but I see similarities between the way that people engage with, you know, Jesus Christ or, you know, or God. this kind of a relationship where you where you're in dialogue almost in constant dialogue but it's just that now what you're in dialogue with or who you're in dialogue with uh is actually the subject um of what you're researching and so you start asking questions to Iasker as well I've had a bunch of really fascinating guests and conversations now with different with people have different perspectives on separating fact and fiction during a psychedelic trip. Like what's a hallucination? What's real? What the hell does real even mean? >> So you ask Robin Carheart Harris, you know, I know you've you've collaborated with in the past, one of the leading psychedelic researchers in the world, but by by credential, and I just think he's just a great speaker and scientist overall. >> And he's like, you know, these are hallucinations. When people see entities, what they're sort of seeing is some sort of deep union archetype that is like a shared culture of our subconscious. >> And I'm like, eh, not totally satisfied with that answer, to be honest. I think he's I think he's incredible. I I think every other answer he gave in that my conversation I was very satisfied with. That one I didn't buy. And then you speak to Andrew Galammore who's done a bunch of research on DMT specifically and DMT entities and he's like convinced that these entities are real, that these worlds are real. And again, it's very hard to define real, but he's like the DMT maybe had some sort of ancestral neurobiology. And when we take DMT, we just kind of flip into this alternate world. Cuz why on earth would we seem to have this alternate setting that just kind of flips in and it's just this crazy other completely different world, but people that experience it say it's real? Like why would the brain have this prediction hardware? And it does almost seem like a setting like you're just switching it into that mode. And why would so many people have this shared hallucinations? Why would people see the same thing and have such similar reports of what they see if this psychedelic noise hypothesis was brought to his end? You know, if psychedelics is just incorporating noise into the brain prediction system, what then you wouldn't really get that much shared trip reports, would you? Or maybe, at least in my mind, you wouldn't expect to see so much of the same stuff. I think maybe culture and shared culture is a partial explanation there, but I just don't think it goes the whole way. So, how do you think about this getting both the western perspective, both the shamanistic perspective? Like, how do you separate fact from fiction in a hallucination in an experience? Like, you must have a bunch of thoughts on this. >> Yeah, totally. I mean, so it's interesting. So, one of the the first things that you have to learn when you're training in shamanism is at least in shapibbo um is how to differentiate what is you and what is external. And they put a they put a distinction on that. They say, you know, it's very different because it's it's very easy and you see this I see this so much with people drinking Iaska. You know, the Iaska told me to do this or the mushrooms told me to do this and half the time it's just something that that the person clearly wants to do. So for example, Iaska told me to buy a Tesla. It's like really like that. Do you think that that could could not just be like your own like like desires kind of coming into into the forefront? >> You see it all the time and is, you know, and some of the time, you know, it's it's quite funny. Other times it can be extremely serious and it can be ego inflation and all of these serious things. But the Shapibo put a huge emphasis on how you distinguish, you know, what is Iaskca and what is, you know, your own internal projection. So that's one of the first things and there's really no way to tell someone how to do that. You have to experience it for yourself. You can look objectively and be like, okay, if I telling me to buy a Tesla, like it's far more likely that that's going to be from my own mind than it's going to be from, you know, the spirit of Iaska. Um but it's really something that you you kind of get used to um experiencing when it seems to be or when it's from an external source. Uh so that's that's one of my thoughts in terms of the the reality, you know, of these these worlds. I think reality is a really that's like a tricky word and that's something that I would try and stay away from. Um I think you know the way that Andrew thinks about these things from what I understand is more akin actually to the way that indigenous communities um describe these things which is that you know entities beings spirits whatever you want to call them. They're not just kind of you know here just you know in the room with us necessarily where you can say they're they're real or unreal. The Shapibo describe them literally existing within us, existing within our consciousness. And you can access them through Iawaska, through states of consciousness, through dreams, through imagination. And that seems to be a pretty uniform across shanic traditions uh across the world and actually throughout the whole of time, which is quite um which is quite reassuring from the kind of from our understanding. And so those things, you know, are they real? Yes. Are they in our head? Yes. You know, is it all consciousness? Yes. You know, is there does it matter whether we perceive them to be in our heads or we perceive them to be, you know, kind of separate? I think we can get tangled in that and we can get stuck in that. So, my understanding of it is that yes, it is all in our head, but that doesn't make it any less real. >> Yes. So, how does that maybe provide a framework for thinking about your demon devil experience? Like, like how do how do you how do you then contextualize that experience in in what you just said there? >> Mhm. I mean, so my perception of that experience is that somebody sent some negative energy to me which didn't exist outside of my consciousness. Um but it was external to me. Uh and so when I was experiencing um that attack as I believe it to be that was that was 100% real and it wasn't me. It wasn't my subconscious that was creating that. But I was experiencing it within my own consciousness because somebody had sent that into my consciousness. Does that make sense? >> No. But of course it I mean I mean the words you it makes I mean of course not in a way. You know what I mean? Like I but also I know what you mean and yes but also of course no because I you know I think it would be one of those things that I would have to have experienced and have to go through for me to be able to even remotely say yes. And then even if I was saying yes I still wouldn't know if that's if that's what happened to you. So does this this sort of does play into sort of a idealist pansychism idea. So like there is some sense that that people can transfer consciousness between entities through say non-physical mediums that we would usually think about like obviously I can you know transfer something to you by speech you know there's pure mechanistic neuroscience materialist explanations for that but you would say that what happened there was sort of a non-material non-physical transfer of consciousness. Yes, absolutely. That's that's the way that I think of it now. And interesting that you bring up pansychism because I think that pansychism is actually another one of the best explanations that we have for these kinds of things, these kinds of experiences. And it's it's interesting because there one of the issues that I find in trying to bridge the gap between western science and indigenous science is that we don't have the frameworks in western science to be able to understand what indigenous peoples are talking about. A lot of the time we don't have the language to be able to describe it. But I think the metaphysics is one of the the closest things that we have that can help us to understand these concepts. And pansychism I think is pretty similar to what the Shapibo believe. But again, I'm even reluctant to say what the Shapibo believe because it's not is not a belief system. When you when you're living with the Shapibo, um this stuff is real. It doesn't matter whether you believe it or not. this is how they experience the world and this is to say you don't believe in it is just that's that's insanity that's ludicrous it's almost like being in the western world and say yeah I don't really believe in gravity I don't really believe in the atom it's like but this is that's just how we experience the world it's not it's not a case of whether you believe or or don't believe in it >> yes and do you think there is a possible scientific explanation for what you just head and and like I'm and when I say scientific I don't mean materialist or physicalist you know I mean like a science that we haven't discovered yet that we don't understand that is maybe even looks quite different to the science quote unquote that we have now cuz I know people that are trying to tackle pansychism from a rigorous angle very smart philosophers that are looking at these these metaphysical positions and saying maybe they are actually a better way to think about or to explain what we experience every today because clearly physicalism and materialism are are extremely limited and not the whole picture. I I believe that now as well. I went into I started episode one of the podcast pretty diehard materialism coming from a neuroscience background and and now I learned the label biocychist which is sort of what I identify at the moment that I think all biological life has consciousness >> um has some form of experience has has an experience of what it is like to be that thing >> in some min minuscule amount I've lost my train of thought now but that >> it's all right I'll I'll help you out I I think uh in answer to the first part of your question, I think that there will be a scientific explanation for everything. Yeah. For everything that that we uh that we experience. >> And I ultimately think that science and shamanism are looking at the same thing. And I think that but we're just quite we're looking at different perspectives. We're coming at a different angle from it. And I do feel that if we get there in terms of you know humanity eventually we will come to the point where we have an explanation for these things that people experience. So for example kind of like what Andrew Gallamore refers to kind of entities existing in these these different dimensions. I think that there will be scientific explanations saying ah yes and we now know that that dimension is you know mathematically it is here and that's something from that dimension. I do think that that will eventually happen. Um, but at the moment, obviously because those two disciplines are so far apart, it they both look ludicrous to each other. Like they both look like insanity to each other. >> Yes. Incredibly cool. I'm so excited to see what that looks like. And that's why I want to have these conversations because I feel like doing some communication and media and distribution of these ideas will only hopefully help them come together. You know, I don't think people will listen to this or of course there's some people that will listen to this and say these are ridiculous. These are completely separate. But I think more people than not from the kinds of conversations that I've been having are very open to kind of anything. Honestly, I think people are sort of having a bit of a an existential materialism crisis and realizing that it just doesn't it doesn't go the whole way and science can't explain everything at the moment and the answer is is somewhat mysterious and up there and out of reach but but possibly, you know, impossible to achieve. I'm really curious to go into Iawaska trip reports because again I I spoke to Andrew Galammore a lot about DMT trip reports and I'm curious when you when you do trip reports with these people that have done Iaska retreats do they experience a lot of similarities in what they see and what they experience? Do they use the same kind of words, the same kind of phrases, the same emotions, the same mental imagery, sensory awareness? like what commonalities exist in Iawaska experiences? >> Yeah, I mean they they definitely do. Um I mean there are various um images that people quite often see in Iawaska which is interesting. So for example, snakes and anacondas is something that quite often comes up. Now whether or not that's you just may you just >> maybe it's not for you. >> It's first thing you said that make me not want to do this. everything. Even the demon, I'm like, I'll fight the de. Although the demon for me probably is just a giant snake. That probably is what it is for me. Sorry, can you please continue? No, no, you're good. You're good. So, there are these kind of these um these symbols that come up time and time again. But it's interesting because these are these are in the in the literature of various different ISAC using communities um describe you know the importance of seeing the anaconda and many people in the kind of the studies that we've been running describe seeing this anaconda. Now whether or not that's because they've done some reading beforehand, you know, they've watched a TV program. Snakes are quite often associated with Iawaska, I'm not sure, but there there are those there are those similarities. Um, I mean there are similarities in the the way that people um experience the uh the Iawaska ceremony as well. Most of my research at the moment >> is looking at military veterans suffering from PTSD and we um send them to the Amazon rainforest and they drink Iawaska over two weeks and we look at them in terms of um psychometrics, qualitative interviews, EEG, epigenetics, gut microbiome, cognitive tasks as a a really kind of multimodal um study. And what we find quite often with these military veterans is that there's the reexperiencing um of some kind of trauma. So quite interestingly with these military vets, we've looked at um just over 80 now with two years into a five-year study with these veterans. And we or I expected most of the veterans to go back to their their trauma that brought them to the retreat which is usually fighting in Afghanistan or Iraq. And sometimes they did, sometimes they did go there, but interestingly where most of them went to was some kind of trauma that happened beneath the age of four. Um, usually something to do with the father. And then they saw how it's interesting how it was always to do with the father or almost always. And but then they saw how yeah how that experience led them to you know maybe not do so well at school you know maybe get into some trouble uh you know feel a bit lost then go into the military have all of these other traumas throughout teenage years or whatever go into the military go to Iraq and then have another trauma but actually that was the tip of the iceberg and the index trauma as it were was actually when they were much younger. So you do see these these patterns with people. I mean obviously it's worth bearing in mind that I'm coming from a clinical lens cuz almost almost all of the participants I'm working with at least at the moment um have a diagnosis of PTSD. And so that's the kind of the the patterns that I see happening with with most participants. >> Yes. It it's very interesting to me that the DMT trip reports seem to be very otherworldly. You know that if you you hear you hear them then they talk it's real to them and it feels as real to them as as the usual waking reality but these are like symmetrical crystal 12fold mischievous mechanized elves you know it's like it's very otherworldly but then when you talk about Iaska a lot of it seems a lot more grounded in you know very warping and very strange but not as alienike or more sort of you say anaconda is sort of this this important symbol. And yes, there's almost certainly very important jungle context there. You are in a jungle where I presume there's lots of anacondas everywhere. I just had a shiver down my spine even just thinking about that for a second. Um why do you do you have any ideas on why that might be? Like what actually is the difference between um someone consuming their sort of maybe more run-of-the-mill vaped or smoked DMT that lasts 10 minutes compared to these iawasa drinks? Pharmacologically, what's different? And then why would one of them produce this alien symmetrical crystal 13-fold symmetry type experience and then one of them not be like that? Or do you still get do you also get that crystal symmetry sort of um experience on Iaska as well? You do, but it it largely depends on the dose. And so people describe that usually with Iawaska, like in my own, you know, personal experiences as well, if you have a a whacking great dose of Iawaska that has usually a lot of shakuna leaves which contain DMT within it. And quite often you get this experience which is akin to the DMT uh experience. So I think a lot of it is literally because of the amount of DMT that's you know flowing through your veins um and is is causing that subjective effect. So let me use this this anecdote to to maybe try and explain that. So I once gave um one of the cordals that I work with um some DMT and he didn't smoke it like he would never do that but it was just to show him like this is this is crystal DMT and he put it on his mat in front of him and he drank Iaska and he looked and felt at the energy that was in that crystal DMT. Now he doesn't know what crystal DMT is like. He had no idea about what that was. We also interestingly gave him some LSD as well and he was looking at that and his response to the crystal DMT was I don't know what this is but there's way too much energy in too small a thing um and there's um the risk of getting confused um as a result of that is what he says when he looked at that crystal DMT. Now it's interesting because hit the nail on the head hit the nail on the head. >> Absolutely. And it's a very it's a very western thing to do, isn't it? To, you know, we try and figure out, you know, what is the, you know, the the most potent part of Iawaska and we find out it's DMT, synthesize that, you know, and then we're going to smoke that and we're going to, you know, have the most extreme experience that we can. And so my feeling is that it's it's likely because because of the intensity of the experience that you get, because of the dose, because of the way that it's entering your bloodstream, and obviously if it's going through the lungs, that's going to be a lot more intense. or even if it's going into your vein if you're injecting DMT um introvenously, then it's going to be a lot more intense. Um and so I do feel that that's probably why you get much more of these kind of the typical kind of DMT um like visuals is because of the dose and the way that you're taking it. Could you do you know ex or roughly speaking what the dosage of DNT might differ between a ser like a a ser a standard serving I don't know if that exists of Iawaska is there a typical dose compared to what someone a typical dose again these things vary a lot of like smoking it or or vaping it or some other form because witha as you say you have the monoamine oxidase inhibitors which means it stays in your system longer that's why the the trip extends for longer. But does that mean that the dose is it a lot less? Are you are you speaking like 10 times less dose or do you have any sense for what the difference is >> the amount of DMT that's in the blood? >> Yeah. Binding to the ser like the actual binding of the to the 5HT2A receptor like you know within a first couple of minutes of of drug onset. >> No, I don't know I don't know that. But if we look at the um if we look at the the time that it takes to get the peak experience, I mean obviously with DMT is happening much more quickly and then the DMT experience is much shorter and so it's much more condensed and but I'm not entirely sure of the the ratio of how much more uh DMT would bind to the serotonin receptors compared to >> right but that's probably what you the scientific explanation at least for the intensity of the experience. would be probably related to the pharmacocinetics there like just how much faster it's binding to the 5HD2A receptor in DMT compared to Iawaska >> I think so yeah I think so that would be that would be my hypothesis >> yes if someone is considering doing this at home you know I'm definitely considering doing this until you brought up bloody stinks but I'm definitely considering doing this like what what what would you advise for people because you said you're also c you're you have a very cautionary voice on this as well cuz you now understand the impacts and the power of this. Um, you know, if someone if one of the listeners is is sitting at home and thinking, you know, I could maybe do with this. There's something about my life that I'm just maybe a bit unhappy about or, you know, maybe I've been researching psychedelics for a while and this this IAS retreat just sounds like I would benefit from. It sounds like something that I could that would send me on the right track. You know, would you advise them to do that? What would you what advice would you give to those people? um you know genuinely cuz there's definitely people listening that they're you know they could have it that flight to Peru bookmarked in their Chrome tabs right now you know like what sort of things should they be thinking about how should they prepare >> yeah I mean the first thing I would say is make sure you're actually going to be drinking Iaska so this is this is one of the the main things you have to watch out for um because there are many many things in the Amazon rainforest that can make you trip and you know there are many people within the Amazon rainforest who who live in poverty and they've noticed that there are huge quantities of westerners who are coming over to the Amazon rainforest uh wanting to trip. They're wanting this this firework display. Um and interestingly IA um for indigenous peoples is more more of a sematic medicine rather than a visual medicine. And they actually say that the visuals can it can be a distraction and the westerners they're so you know obsessed with the visuals and whenever they brew when westerners brew Iaska they make it super super strong with lots and lots of DMT and they the nickname for that is gringo because you know these it's like oh it's so strong it's gringo because these people they're so obsessed with these visuals and so if you do go to Peru you have to really watch out and that you're working with somebody who is actually an iow who is somebody who potentially knows, you know, how to brew Iawaska who's actually using Iawaska. Um because there's a million things in the jungle that can make you drip and many of them make you go psychotic, uh, you know, or can be lethal. So, that's one of the first things that you need to watch out for. Uh, making sure that you're drinking with somebody who has a good reputation, somebody who's trustworthy. All of these kinds of things are super important. And that's before we even start to think about appropriate preparation and integration. What would that appropriate preparation look like? Do you think someone should try a lower dose of a different psychedelic first in a safe environment, you know, hopefully done properly? Like, is that step one because going straight into the jungle seems like level 100 right away. Maybe go somewhere, you know, there's places where you can legally do these things, right? So maybe they go somewhere that where you can legally take, you know, like a low dose of psilocybin or something. Um, you know, is that is that something that's generally advisable first or do those people have better outcomes? Have you observed? >> Uh, I wouldn't necessarily, you know, I wouldn't necessarily think that. I mean, for sure there are similarities with psychedelic experiences, you know, and so if you want to have an idea of what Iaska might be like, then it can be worth, you know, taking psilocybin beforehand so you can be better prepared. But I really, you know, I really don't think that's necessary. I think that in terms of in good preparation is really being clear on your intention, you know, like why are you doing this? Like what is it that's driving you to do this? And then giving the giving it the appropriate time, space, and respect. And it doesn't matter, you know, what you believe and your belief system surrounding IAS. Just give yourself the appropriate time and respect. you know, are you willing to take a decent amount of time off work, you know, before and after so that you don't have to suddenly go back to working on a bank on Tuesday after meeting Ganesha over the weekend and you have no idea what reality is. You you know what I mean? It's that's a very funny image of it. >> Yeah. Yeah, that makes sense. >> Yeah. Like can you can you give that time? The most important thing in my experience is stillness. Stillness in the mind. Can you try and get to a point before you drink Iawaska that you've began to calm down the you know the wildness of western life when you try and get to this sense of peace so that you can listen to whatever it is that's coming up from your own mind from something else doesn't matter and in order to do that you need to calm down everything. You need to calm down your diet. You need to try and make it kind of bland so that there's nothing that's shocking your system. You need to, you know, watch your intake and that's not just what you're eating, but also what you're watching, the conversations that you're having. Just calming everything down to the sense of stillness and really giving it that time and respect. It's almost like if you're going to therapy, ideally before you have an hour's therapy session, you should like to have maybe kind of 10 minutes beforehand, gather your thoughts, you know, how has the week been? Rather than you just sprint into the therapy room, um, sit down. It's going to take you a while to kind of to put your thoughts back together. So, I I see it as being akin to that. >> Yeah, I've just had the It's so enjoyable to read through people's trip reports. I'm lucky enough now that since I put out a few of these episodes, I get thousands of these now. And, you know, every single week reading the most hilarious, and I hope I can say hilarious cuz they also say, you know, haha, it was hilarious in in the comments. You know, some of them are very serious, but some of them are just goddamn hilarious. Like I had an one guy took salvia and then became a conscious piece of corn that was in a bag of other conscious pieces of corn and they were in a back of a truck going across America. And I'm like that's just hilarious. And he was just he said it was great. It was just a conscious piece of corn. It was great hanging out hanging out with his other corn buddies and he was just kind of passing through corn fields and it was just like I don't know what that means even remotely but he said it was one of the most positive experiences of his life, >> you know. >> Yeah. What's super interesting is is and again this might be there's definitely a bit of a confirmation bias here and the people that choose to comment and share their experience but even people that had incredibly terrible experiences like horrendous experiences they would then go on to say it was of the most impactful and positive experience that they've had in their life because of the aftermath like what how it changed them afterwards. you know, people saying that they lived entirely other lives with other families and had to grieve the their their children that they had in this 10-minute salvia trip that felt like 5 years, but then it completely changed them as a person. You know, it very often changed their their psychological relationship with substances. You know, the probably the most overarching theme is like I had an alcohol problem. I was smoking too many cigarettes. I had a porn addiction. And then, you know, being folded into a chair and living a 24-hour life as a conscious chair was the thing that just >> it's exactly what you needed. It's >> like, what would have guessed? And they're like, and then I was just I didn't want to smoke anymore. And I'm like, god damn it. Like, why? That's so bizarre and so strange. >> Like, >> it's so weird, isn't it? >> It's just so strange. Um, let let's get let's get to these epigenetic studies. So, this is super interesting. So you ran the first psychedelic and epigenetics study. So first off I guess >> what is epigenetics? I guess it might be maybe a good place to start because that's kind of a word that's thrown around a lot. >> Yeah, totally. So the field of epigenetics is looking at the way in which our environment impacts the expression of our genes, the expression of our DNA. And so it doesn't our DNA doesn't change but the certain genes that are expressed changes as a result of our environment. And this is true for for everything. So it depends the genes that are expressed within your genome depend on the environment that you live in. Uh so the air quality, the amount of food that you eat, uh the amount of stress that you're under as well. And then these epigenetic changes which are on the DNA affects proteins on the DNA. These are then passed down or at least it seems very likely that these are then passed down through various generations. And there are studies that suggest um they can be passed down in rat studies. It's 13 generations that they're passed down before it kind of reverses or kind of those epigenetic tags begin to disappear. But then there are other studies. So for example, looking at survivors um of the Holocaust and their children uh suggest that their children are more uh prone to stress and also other studies um that suggest that similar findings as a result of people surviving the Dutch famine and that they're more prone to stress as well because of the stress that happens during that famine. And the way that it works is by either um histone modification or adding on these little um epigenetic tags onto the proteins on DNA itself as well. >> Okay, brilliant setup. So now what what did you look in for your study and how psychedelics impacted these epigenetic markers? Yeah. So we were looking at um specifically looking at one particular marker um called the sigma one gene uh and that gene is associated with many different things. It's associated with neurom modulation with inflammation uh with stress and DMT. The reason we were looking at it is because DMT also binds to sigma 1 as well as the serotonin receptor um the 5HD2A receptor. And we found that there was a an upregulation in the sigma 1 gene, but it was only a very small upregulation. And the sample size that we had um was it was 50 and 50 people and you need really kind of hundreds and hundreds before you can make solid conclusions surrounding epigenetics. So it was really it was a signal that we should be looking at um IASA and epigenetic change in greater detail. And so now in the studies that we're doing looking at Iawaska with military veterans, we're doing genomewide analyses. And so we're looking at the entire genome. And so that's much better because it's it's less biased. We can look at uh genes that, you know, we think that Iaska might have an impact on and also we might find genes that we didn't think I was going to have an impact on. And what I'm most interested about with that study is whether or not um Iawaska can change the expression of genes. So either crank them up or crank them down. Um so crank down the expression of genes that are related to trauma. So, for example, there are certain genes like the um genes related to the expression of cortisol um which are almost definitely cranked up when people have PTSD um because they have higher levels of cortisol um in their in their body and their blood. And I'm interested in seeing whether or not drinking Iawaska could crank those genes down again, almost like as a reset, as a reversal um for people um when they come back from war or when they're trying to uh work their way through a traumatic situation. And that's particularly interesting for me because that could be a biological mechanism um of action for Iawaska. I think this is one of the most beautiful things for me about Iawaska is there are so many different ways that you can look at it. So you can think of it in terms of psychological mechanisms of action, spiritual mechanisms of action, biological mechanisms of action and they're all as valid as each other. Um yeah, I just find it endlessly fascinating. So would the hypothesis be here that if I took Iawaska, I would not only become more resistant to trauma myself, but my children might become more resistant to trauma because I would pass down those epigenetic markers to my offspring. Is that the hypothesis not proven yet, but possibly? >> Um, it's more that the impact of trauma on you and your life um wouldn't be passed down to your children. So if you have PTSD uh and you now are more prone to stress as a result of you know tuning into stress with your um your epigenetic change cranking up >> um the kind of the stress markers on your genome that you could reset that and bring it to a baseline level so that you don't pass that on to your children. That's really more of the hypothesis. Gotcha. So if I myself, you know, I've never been lucky enough to say that I've never really suffered from much negative mental health in my life. I'm not going to get 110% protection if I take Iawaska. My children, you know, are not going to gain an additional bit if if there isn't some predisposition that I already had or was already actively suffering from. Again, I guess is the hypothesis unproven? >> Yeah. Yeah. Yeah. Yeah. I mean that that could be one way of thinking it but but again you know so for you if trauma you know thank god isn't a big thing that you've experienced in your life I'd be particularly interested to see you know where are the epigenetic changes that perhaps it would be better to uh to reverse or to reset and that would be passed down onto your children and I'm not sure that could be based on lifestyle that could be based on on diet on you know air quality all of these different things >> right >> I'm curious because you just gave a very western science um interpretation of those results, right? What did the Shapibo think about these results? I presume you ran you ran this study in conjunction with them, right? So, when you give them the data, when you explain this to them, like what what do they think about it? >> Yeah, I'm really glad you asked that actually because there's there aren't that many times when Western science maps on to indigenous science quite neatly. Um but epigenetics is one of the ways where it might. So when I was explaining to the shipbo about you know the results that we'd got you know and of course I'd spoken to them about epigenetics and the theory behind it and their response was yeah of course of course that happens you know I was very excited to say you know we found that there's you know like a change in regulation of the sigma 1 receptor and that could suggest that genes are being um the expression of genes are being reversed if people are traumatized so we're going to keep looking at it and they just said well yeah we've we've known that for thousands of years. Um, we we know that duh >> the Yeah, exactly. Yeah. We know >> we know that if you treat if we treat you then it's going to affect all of your generations to come. We call that cleaning ancestral lines. Um, and then Don Renault, the Shapibo Cord apprentice under went on to say, and I've been doing that to you, Simon, for the last couple of years. You just like didn't know. I've been like sorting that out for you. so that you don't pass your own traumas on to your children. And so there is this these these times occasionally where western science and indigenous science do kind of marry up and they do meet and I make a point of trying to kind of explain to people when that is the case. It's quite nice to see when there are different explanations of the same thing. >> Right. Super interesting. >> While we have a a Britain or Irishman on the podcast, let's go into generational trauma. This is a >> He went there. He went there. >> This is something I've been told my whole life in Ireland. You know, we have this generational trauma um from the famine. Um and don't worry, Simon, I only blame you for like 10 to 15% of the of 800 years of colonialism. Like it's only No, I'm kidding, of course. But but this is something that you hear, but I never have really heard from scientists particularly. So I've never I've never really heard a convincing mechanism or if there was actual proof of this. I think >> this seemed like a narrative that was told even be before we had before we knew what epigenetics was and then we kind of discovered epigenetics and then suddenly oh everyone was pointing at like oh that's clearly it. So kind of reversing you know reverse engineering the evidence onto a narrative that we already had to some extent. >> But is there any real evidence that this actually exists in humans? I believe that you know we've been told a psychological story and that can carry down through generations psychologically >> but is there any evidence that there is genetic changes? M I mean genetic changes the the only evidence that we have of that are those two at least that I'm aware of are those two studies which are preliminary studies looking at you know the Dutch famine and also survivors of the Holocaust and they do suggest that there is epigenetic change which is passed down through generations but that is by no means enough to make solid conclusions on but it's interesting because when we think about um uh other mental health conditions depression anxiety schizophrenia OCD the the list goes on. Um there definitely is um familial factors involved in developing those conditions. Now the question comes down to nature versus nature, nature versus nurture, sorry. Um but I mean 100% if your family um has suffered from anxiety, you'd be far more likely to develop that and to develop anxiety. And we see that, you know, I see that with so many patients that have anxiety, your mom had it, your mom's mom had it. It seems to run in families. These conditions do run in families. Whether this is intergenerational trauma or not, I'm not sure. But my perception of um actually I think that most mental health conditions, not all of them, but most of the time they usually stem from some kind of trauma. Um and so in that way, I guess it is intergenerational trauma. Um, but again, I'd be I I don't think we can say at this point or we can't say at this point that there's genetic evidence to back up ancestral trauma, >> right? Because I think there is lots of valid explanations for intergenerational trauma, right? If someone is traumatized, they're going to pass that trauma down to their child unfortunately and I think lots of ways, right? They're going to, you know, have those moments of not being able to maybe regulate their emotions properly, lashing out, whatever. There's a there's so many ways that someone again just through their behavior can pass down that that trauma. But I was curious, was there actually good evidence of like this happening at a DNA epigenetic level because of some event that we could even isolate and say this was the this was the traumatic event for the entire population. Because again, this this narrative still really common in Ireland, but I just don't know if there's any really good evidence for it on an epigenetic level. You don't even need really need to invoke epigenetics. I guess we just have >> a bunch of other explanations that are pretty valid. >> Yeah. So, yeah. I mean, like we just said, I mean, there's a bunch of explanations that can explain it. In terms of epigenetics, there's those two studies which you can't draw solid conclusions from, but you do have a signal. You do have a signal. So, I think it's a it's a promising theory. It's a promising theory yet to be proven. >> Where do you think are the other really big benefits of Iawaska? I was reading some of the the studies that you've done and they are truly amazing. the effect sizes can be can be massive. Do you want to highlight maybe one or two of the really big results or impacts that you've run in your studies and your collaboration with row carts with Robin with with any of these other amazing organizations or scientists? Like where have you seen the biggest impact for IASKA? We've talked about PTSD. Maybe go into that a bit more if you want, but we can also go to elsewhere. >> Yeah, for sure. I mean, it's fresh in my mind with with PTSD. So, so far we have with the 80 participants that we have um you know had going through these IASCAR experiences these twoe Iaska retreats at sixth month followup we find that again over 80% of those participants no longer meet our criteria for PTSD and so that's a huge finding that's a huge proportion it's 80% no longer meet the criteria for PTSD And that's also not just after the retreat. That's longterm. That's 6 months later. That's huge. Now, I need to caveat that by saying these studies are observational. You know, they're not done at randomized control settings. They're not done at hospitals. Um, you know, so we do need to recreate them in hospitals. Also, the data isn't published yet. Um, because we're still in the med middle of the study. We still got another couple of years on that study. But even so suggestive that what's happening there um is is incredible. They're really really incredible results. The effect sizes are huge. I mean you almost don't read effect sizes like that for anything other than psychedelics. The numbers just seem insane. And like the sensation from like heroin addictions, the addiction numbers just again the effect sizes on these seem massive. Like continued sessation of of something people have struggled with for decades. you know, it's in the upwards of like 60 70 80% of people are still you, you know, quit the addictions of I think either heroin or smoking. Speaking to Grace Bless Topppley, I I believe you've collaborated with her. You know, these are just crazy crazy numbers. >> And is this is this ongoing integration, ongoing therapy? Is there a protocol these people follow over these eight months? It's not just boom in the jungle and you're gone. Like what do these people do as an integration protocol after the experience? Mhm. Yeah. I mean there is an integration protocol but it to be honest is minimal. It's minimal. Um and that is largely because of funding. So it's heroic hearts which are a fantastic organization uh not for profofits that work with military veterans who suffer from PTSD sending them to psychedelic retreats. Um but the protocol literally involves a couple of uh or three preparation sessions, three integration sessions, one-on-one and then also group integration and group preparation as well, which in the grand scheme of things really isn't that much. Like it really isn't that much at all. Um I would really like to see how the results improved even further when there was a decent amount of prep and integration. I mean what I always say to people on these studies is it would be ideal if you were in kind of continuous therapy and then you had IAS like whenever you decided it was necessary uh and then continued your therapy your prep and integration work that would be the ideal way of working um with I think with most psychedelics but certainly with IAS if you have something that you're trying to work through but there is just a reality both in observational studies and in the lab based studies that there's only funding to do so much and so we you know we make do with what we have. >> Yes. >> How important do you think the environmental context of the ceremony you're in a jungle? There's something kind of mystical and scary called a shaman that's giving you the bowl that you're going to drink that was on a tree like a week ago. you like all of this is like added importance and added relevance to the nervous system and like oh my god this is all so different and I've just flown you know 6,000 kilometers or whatever it is to Peru and and I've gotten a one day canoe down the river and like everything about this is just so and you know it's also new and novel and weird and strange and you're just not really sure how to adjust like how important is that when you package all of that together into the experience that lasts then for months months on after with the therapeutic benefit, you know, how much is how much can you really tease apart the substance from the environment, the ceremony and all the rest. >> I think that it's is vital and you you can't and this is this is an interesting thing because whenever I publish research, this is always the response that reviewers come back with is well, how did you know that it was the effect of the Iawaska rather than the fact that they're in the jungle, the fact that they're in a ceremony, that they're away from home, they're away from family stress, etc., etc., etc. And my answer to that is that you you can't like you you can't separate Iawaska from the ceremony. You can't separate Iawaska, you know, from the academy. You can't separate Iawaska from shamanism. And if you do, then I would argue you don't have Iawaska. You have a DMT MRI combination that you're giving to somebody in a hospital-based setting. And another really interesting thing with this is when you look at the way that this really kind of throws the you know the mechanism of action of Iawaska kind of up in the air for debate but the traditional way of working with iawaska involved the cordero drinking iawaska and the participant didn't drink iawaska sometimes they would but most of the time they would so the cordo would drink iwaska they would then experience visions they would then you know connect with their spirit spirits. They would then ask the spirits to heal the participant on their behalf. Um, and they would also get information surrounding the diagnosis of the participant by looking into them and they would have information surrounding the plants that they needed to give them their prescription. And the participant wouldn't drink and they would and you know that's that form of shamanism has been done in the Amazon forest for thousands of years. It looks like thousands of years. And so then suddenly from a western perspective we're saying well actually you know I think it's because DMT is you know binding to 5T H2A receptors and then we're having increased neuroplasticity and like the amydala fear center is being dampened and then the prefrontal cortex is being heightened. It's like yeah yeah yeah all that stuff is happening for sure but could there be something else that's happening that we're just completely ignoring and we are. we literally are ignoring what the Iaskeros, the people who work with Iawaska say is the most important part um of of the Iaskar experience. And I think that's really really interesting to look at as well. And as scientists, we shouldn't be just be completely ignoring that because my feeling is that that in itself is unscientific for sure. Wouldn't that seems to be a great control group for the study, right? If you got an equal amount of participants and you brought them over and you did the 24-hour canoe ride and the long plane and the ceremony and the music, but they didn't take the substance and the the shaman took the substance, it seems like comparing those two groups would be a really fascinating result. Like, do you see the same level of PTSD benefit in that group or what what's the effect size difference? you know, cuz that that seems like you're getting it's it's hard to control for everything, but you're almost getting everything except the substance there. So, it seems like a good way of isolating the importance of the substance itself. >> Yeah, totally. And I actually tried to do that study. Um, but the ethics board, uh, I'm not going to say the name of the university, throw them under the bus, but the ethics board that I I put it forward to said it was too similar to a randomized control trial. uh and they didn't want to for whatever reason they didn't want to to give ethical permission uh to do that study. >> Wouldn't that be a positive? >> Wouldn't that be a >> No, I know. I know. I thought so. >> But this is too similar like the science that we usually do. You can't do that do it that way. >> What sort of what sort of explanation is that? >> I know it was it was super frustrating. >> Since Since then I have now changed to a much better university called the University of Exa. So I'm hoping that they're going to allow me to do that in an upcoming study. But yeah, absolutely that is that is the question. But then I'm also hesitant about putting anything that can result in western science being given the ability to either validate or not to validate indigenous science. And the risk of that study that we have to consider is that say that there's no difference in our measures would the it would be easy then for people to say okay well actually we know that it is Iaska drinking the Iaska which is having the outcome and therefore the shaman is redundant. you know, that could be a conclusion that we could come to, but that's not considering the fact that it's pretty unfair that we're looking at we're using Western science as the paradigm to either validate or not to validate shamanism. And it's very likely that, you know, if there is validity in shamanism, our measures aren't able to pick up on everything the shaman is doing. um we quite often see uh or actually in most of our studies that it doesn't matter whether or not you've taken Iawaska it's more than three times or up to 20. So if you take an Iaska 18 times or 12 times or six times it doesn't have any difference on your measures relating to depression, anxiety and general mental health. >> That's interesting. >> Yeah. Which is super interesting. But and then the one conclusion that you can draw is Yeah. So you only need Iawaska three times and then it doesn't lead to any you know any further benefits. But the subjective feedback from these participants and what the shamans are saying is no I feel much better and the shaman saying yeah we not only work through your trauma but we've started removing the trauma from your family started like and giving you good energy all this kind of stuff. Now, could it be that we're reaching re reaching a ceiling level with the measures that we have and that our questionnaires are showing yes, there's no more depression, but actually there's a whole host of other things that are happening that we just don't have the right tools um to assess and to pick up on. So, >> as with all of this research, we can ask really interesting questions, but then we also have to watch out for the conclusions that might be drawn um especially when they might be inaccurate and unethical. >> Sure. Makes sense. I know. I know we can't know, but would you have any predictions on if someone did take the Iawaska brew in a, you know, dull, depressing hospital room in Bath? Like what? >> Bath is quite nice. I don't know why I adapt Bath there. I was vicious fangs out for Bath. I never even been to Bath. Um, anywhere, insert any sort of, you know, typical hospital in the UK or Ireland makes no odds. I'm not I'm not UK bashing here whatsoever. I I'm just I'm just I'm just comparing the context. Like would you make a prediction that that's going to be half as effective? Would you even just I can't even make a prediction. Do you have any thoughts on like what you would expect the effect size difference to be? Would there be one? >> I mean, so there have been studies that have been done looking at many studies that have been looking at in hospital-based studies in hospital-based settings and they all have really good results. They all show that there are, you know, massive improvements in everything that you would expect. Depression, anxiety, you know, all of these kind of increases in openness in personality, all of the classic things that you would look at. Um, but again, I think that there are a whole host of of other things that potentially we're not able to measure and we're not able to look at. What I will say though is that usually the effect sizes are much higher in the observational research than it is in randomiz randomized control trials. But that's also normal. It's also normal that observational research will have huge effect sizes and then when you bring these things into hospitals the effect sizes get um get much lower. I mean my perception on that is that I mean I think that is just kind of one of the things that happens when you take and translate observational research into you know more controlled settings. But I think also you're beginning to remove many of the the ways that Iaska works and you're just isolating one mechanism which is the pharmacological mechanism. And so if you remove the shaman, you know, at least according to shamanism, you've removed the most important person. You've removed you've removed the main mechanism of action. Also, you know, like the setting being in the jungle is hugely important in shamanism. You're surrounded by the plants, the spirits. That's one of the things that gives the shamans, you know, their power. So if you remove that, then you've reached another mechanism of action. So from a shamanic perspective, you're just literally just looking at one tiny way in the way that Iaska works. And so of course that's going to make the effect sizes smaller um in my opinion. >> Right. Super interesting. I find all this super interesting. I really I really want to try this. I do want to try this. I I considered doing a podcast while doing this. I don't know if that's uh >> I don't know if that's possible >> in the most respectful way. Yeah, exactly. In but in the most respectful way to the practice and try and not doing it in any way other than this is as genuine a trying to, you know, relay the experience as it happens. Um would I be possible, you know, capable of speech or do you think I would just absolutely not be capable of speech? >> I mean, I think you probably would be capable of speech. I'd also kind of question whether that's something you'd want to do and do a podcast on Iawaska. Um, yeah, I'm not sure. Have to have to have a think about that. >> Do you have an idea in your mind of what the spiritual mechanism of action is? Because we've talked a bunch about, you know, you listed off sort of we have decent hypotheses on what the scientific mech mechanism of action is. Does it even make sense to try and verbalize the spiritual mechanism of action? Is it something that is translatable into language? I'm curious to know how you even think about that because I don't you know you've spent so long thinking about this and you've had so many experiences like how do you think about the spiritual benefit detached from you know the rigorous scientific data that we have in the empirical experiments just on the spiritual side like what what do you think is actually happening there? M yeah I mean that's that's a a huge huge question you know and I think that um again from a a shamanic point of view there's only so much that you can understand as a human it's almost like saying that question is almost like saying what's the the spiritual mechanism of God you know like how does how does God help people >> so it's it's really hard to answer I mean but >> but a few kind of tangible things you know what what I've seen and experienced and you know have been training in is there's usually removal of something whether it be some kind of blockage whether it be some kind of attachment you know like something like that and then there's also kind of filling filling with with positive things as well and that is just you know so high level it's it's ridiculous but um but again it's almost like a um an ineffable question um that it's impossible to answer >> my I totally get that my ignorance was on display and even asking that but you know I just I don't even know what the right way to talk about this is and since I'm coming from the science background and really trying to understand all the other aspects I'm like willing to ask the dumb question to just because I totally get that some of these questions might not have answers doesn't even make sense to talk about it that way but I'm just curious on hearing your perspective on this and how you think about these sort of things or how what are the frameworks and models you have in your mind for for thinking about these things because that you know there's just so much more advanced than than mine the listeners you know That's why it's just curious to even hear you say it's like the mechanism of God, you know, that's revealing in of itself. >> Yeah. Yeah. Yeah. Totally. But as I say, I mean, thinking about it from a spiritual point of view, that that is one way of thinking about it. But, uh, you know, I I find that the the most holistic way to think about it is the kind of the spiritual mechanism of healing, but then also the biological, also the psychological, and all of it together. When you bring all of it together, you begin to get a more holistic idea on how Iaska works in my opinion. And it gets easy to kind of to get focused, you know, in, you know, the western world and being from a science background, we're so obsessed with the biological, you know, and the psychological. But then it's also very easy to get completely obsessed with the spiritual. You see many westerners who get into get into spiritual ways of thinking just like completely think about it from that point of view and completely, you know, disregard it doesn't matter. And it doesn't matter that ser that you know ISA affects serotonin receptors. It does. It doesn't matter Iawaska affects epigenetics. Like it does like these are all completely valid ways that that Iaska works and and I think that yeah focusing on all of them is really the way forward. >> Yeah. I I love that time and I think you're awesome. I think the fact that you can juggle between these two again seemingly opposed forces is so fascinating to me. I love I love when you when you connect them when you bring them together and when you demonstrate to the ignorant like me that you know maybe they're not as opposed as we might think and we need to be very open-minded about it. What would be your like one dream experiment that you could run now if you had you know 10 billion in funding and ethics ethics approval. Um you only have your own ethics to follow by which I you know I assume is rigorous enough by the sound of this conversation. like what what would you do tomorrow if you had if you had all the money um and like what would be the the one experiment? What's the most interesting question? What what what would you aim to do? >> That is that is a really really difficult question. Um, you know, something that that's on my mind that I would like to look at is so in the in the Amazon rainforest where um if you're working with the Shapibo and they're kind of adhering to this animistic uh view of the world, they quite often describe different plants as having different personalities. The different the spirits of these plants have different personalities and you work with different plants. Um, and when you work with them enough, you begin to come like them. You begin to become like the spirit of that. So, for example, if you >> need some kind of protection, you might want to, you know, work with a plant called churaki and you become very kind of strong or maybe kind of like slightly mischievous and various other manifestations. And various other plants have different personalities. I would like to run a study where you assess personality changes in people who have been working with particular plants um to see whether or not the described characteristics of these plants are manifest um in the people that are working with them. I think that would be super interesting. >> Now I think about it, the issue with that though would be ideally you'd have it blinded, right? So you'd have to blind the people to which plant they're working with, which might be more tricky, and then see if they develop those characteristics. But something like that, I think looking into this practice called master plantetas, which is it's the cornerstone of Amazonian shamanism. is when you go into isolation for long periods of time, weeks, months, and sometimes years, and you just consume small amounts of a particular plant to get to know the spirit of that plant. Um, that's something that I'd really I'd really like to look at. >> Fascinating. Yeah, you're right that of course blinding there is is crucial because if you have an idea and a if your perspective is that this plant is is energetic, you know, of course by by the rules of you think something, it happens. um you know that's going to make you more energetic. But if you blinded that and actually did find some significant results, I mean that would be so interesting. >> Scientist and be like go on explain that then huh come on try try explain this Mr. Mr. Science Man. You're like that would be so so interesting. >> Yeah, it's fascinating isn't it? It's endlessly fascinating. There's so much that you could look at. It's Yeah, there's such a pleasure to be doing this work. Kind of similar to you. I think I reflect on my job almost daily and just like I can't believe I get to do this. This is so amazing. I love it so much. >> Absolutely. >> Yeah. I resonate with that so much, man. This has been such a pleasure. So So fun to meet you. Such a fun conversation. I hope we have many more conversations. I would love to try this sometime. >> I don't know when. I think I you I would love to try this eventually. Um you maybe I'll I'll hit you up if I'm if I'm ever actually considering booking that flight. But super super interesting, man. Great conversation. You're really a great hospital in Bath, you know, if you want to go and do it. I know a great hospital in Bath and we can kind of give it to you there and see how you get >> on. I have this I have a one by one jail cell for you. Um, >> I deserve that. Thank you so much, man. Absolute pleasure. So much fun. >> A pleasure.
