Ido Hartogsohn on the influence of society on the psychedelic experience

collective set and setting
Ido Hartogsohn is one of the first and few researchers to focus on psychedelic research from a social technological perspective. The assistant professor from the Science, Technology and Society program at Bar Ilan University in Israel has just published a new book called American Trip, in which he explores how the social conditions of the 1960s shaped the American psychedelic experience itself. 
In his recently published book he inquires how the LSD experience was shaped by the social conditions and predominant values of the fifties and sixties, portraying LSD as a “psychopharmacological chameleon” dependent on culture. With this move, he expands the traditional meaning of set & setting in psychedelic therapy to include the broader contexts in which these substances are used. He calls this the “collective set and setting”: the broader cultural and social contexts in which these substances are used. 
His work brings a sociological perspective that invites us to rethink psychedelic drugs beyond their mere pharmacological properties.
How do your views challenge conventional understandings of drug effects in pharmacology?
One of the defining ideas of pharmacology is an often implicit notion which scholar Richard DeGrandpre termed pharmacologicalism: the assumption that a drug is exclusively defined by its inherent pharmacological qualities – that it has one type of discrete effect independent of any variables.
The closer we look at the effects of drugs, the more we see that they do not work like that at all. The effects of drugs, not just psychedelics, can change radically depending on the social and physical environment.
Think of the example of US soldiers returning from Vietnam in the 1970s. The American army tried numerous plots to help these soldiers kick their heroin habit while they were in Vietnam, but all of these ultimately failed. Then, as the soldiers returned home, suddenly 90% of them were able to kick the habit spontaneously, without going through any kind of treatment.
Once the setting changed we could see that – even in the case of the supposedly most rigid, inflexible and essentially physical drugs, effects were highly dependent on the set and setting of use.
This is something that pharmacological discourse has been reluctant to acknowledge over the years. It makes sense because once you acknowledge that, it complicates drug trials and discussions around drugs. It forces us to think about not only the very chemical product that we give to patients but how we give it to them and the whole clinical environment. It also forces us to forsake these very naive ideas of drugs as magic bullets that have one specific effect and one specific and highly discrete application.
The cultural malleability of psychedelic experiences has great implications for drug policy. How do you think that prohibitionism and anti-drug propaganda could have infiltrated the very experiences of psychedelic users?
There is this classic study by the sociologist Richard Bunce about the dramatic increase of bad trips at the end of the 1960s as authorities were pushing different scare theories such as the idea that LSD creates chromosome damage or that it will “fry your brain”. All of that stuff was completely debunked later on but once you have these ideas percolating inside the culture, they can easily penetrate people’s experiences. Given this type of ‘collective set and setting’, levels of paranoia shot up among users. Experiences that could be interpreted as quite benign and pleasant turned in a way that is very scary.
This kind of effect is something anthropological literature was predicting already a decade earlier. In the late 1950s, anthropologist Anthony Wallace argued that psychedelic users in the West were more liable to have negative experiences than those that had them in traditional or indigenous societies. Societies, like in the West, that conceive of hallucinations as something that is inherently dangerous and meaningless increase the chance for harmful experiences.
I believe that there have been so many psychedelic trips gone awry as a result of prohibition; so much mental energy that has been squandered; so many positive experiences of users over the years that took a bad turn when they for example encountered police during a trip or were somehow perturbed by the ideology, propaganda and policy of the war on drugs.
So, if we are to take a harm reduction approach to drug use, what can we do to improve the collective set & setting of psychedelic use today and in the future?
One of the most beautiful things that is happening today in the so-called “psychedelic renaissance” is this burgeoning culture of set and setting: the growing awareness of the importance of preparation, intention, and integration – of knowing your substance, your set and your setting.
Psychedelic users today are much more “psychedelically literate” than the ones in the 1960s, and that’s a result of a very rich culture of discourse and practice informed by the idea of set and setting. So we now have safezone organizations which provide for example psychedelic first aid or peer support in festivals like Burning Man or Boom; we have online trip-sitting services run by volunteers; books and websites guiding about the principles of safe and transformative psychedelic voyaging, and there are more and more studies that aim to study how set and setting work.
These are all very hopeful signs that the appreciation of the importance of set and setting is more and more widely recognized in the field of psychedelics, for the broader community as well as for the clinical community.
Governments that want to approach this subject from a progressive perspective need to realize that outmoded, ideologically rigid approaches to drug use fail their citizenry and ultimately the entire society. Governments are betraying their role when they prosecute users. What they should be doing is helping the general public get the know-how, the information and the resources that could help minimize harmful experiences and maximize the potential for safe, positive and meaningful experiences.
You argue that the placebo effect can be understood as a form of meaning response, in which clinical improvement follows from the mere manipulation of meaningful cues in the therapeutic process. Accordingly, the meaning-enhancing properties of psychedelics turn them into some kind of “super-placebo”. What would be the consequences of this reconceptualization for current clinical trials with psychedelics and their placebo-control methodologies?
Over the years the pharmaceutical industry has been invested in the attempt to minimize or eliminate placebo effects. If you are selling a drug like they are, you probably want to give a decisive answer about its effects. But once [the placebo-effect] enters the picture, it appears much more uncertain what the drug actually accomplishes by itself.
After clinical trials, we see that the efficacy of that same drug diminishes from year to year of use in the market, or from culture to culture, because of the changes in the placebo response and in the meaning attributed to the drug. We can therefore see that drug effects are much more fluid than we are led to believe.
Medical anthropologist Daniel Moerman draws our attention to the fact that placebo response can more intelligibly be conceived as just meaning response. When you bring this insight into contact with the field of psychedelics something quite interesting emerges, because one of the main effects of psychedelics is to enhance the perception of meaning.
This then raises the possibility that psychedelics may enhance the placebo response by enhancing our perception of meaning. This potential of psychedelics to enhance placebo really holds a valuable alternative to the classic pharmacological model and an opportunity to think about how meaning intervenes in therapeutic processes.
I don’t think that we are about to see the end of the blind trials paradigm anytime soon. But rather than looking for an objective response to a drug and leaving it at that, we would achieve better results if we focused our energy at examining the nexus between drug, set and setting, to optimize the overall therapeutic process in a way that transcends commonplace flat and impoverished conceptions of the drug responses.
You have approached psychedelics from a science and technology studies (STS) perspective. What has that taught you?
When you look at LSD and psychedelics in general, you have a technology whose effects are highly malleable. Depending on the set and setting, a hallucinogenic agent like LSD can be a psychotomimetic (psychosis mimicking) and it can be therapeutic. It can be anxiety-inducing and it can be mentally soothing.
The effects of LSD are so radically transformed in relation with user’s mindsets and settings that you could argue that LSD, as a technological artifact, is recreated every time it is used. This recognition leads to the concept of psychedelics as a technology that is culturally and socially constructed in a radical way.
One of the main takeaways that I am trying to convey in my book is the idea of a “psychedelic technology”. Going back to the very meaning of the word psychedelic as “mind-manifesting”, the category of “psychedelic technology” would then refer to technology that is shaped in accordance with the mind-set and the environment (hence the idea of an ecodelic) of the user. This is an interesting way to think about technology that is a radical extension of the social constructivist way to think about technologies in the field of STS.
My perspective on psychedelics later shifted to the STS idea of co-production, the question of how the effects of LSD and other psychedelics are shaped and formed by social values, norms and conditions, and how LSD and other psychedelics simultaneously bring about changes in social and cultural movements creating a kind of positive feedback loop, an idea that I explore in my book.
What will be the major takeaways that potential attendees of ICPR might expect from your talk or about your book?
One of the main things my book tries to do is to really expand our understanding of set and setting in order to transcend that more narrowly defined, individualized concept of set and setting. I think the book makes clear that no factor in the individual, specific or concrete set and setting of a psychedelic experience is independent of the larger social and cultural picture, and so I try to answer the question how our collective historical and social forces worked to shape the psychedelic experience in the West since the 1960s and to this day.
Ido Hartogsohn talk at ICPR 2020 will explore the relationship between set and setting, meaning-enhancement and placebo as a central axis on which the psychedelic experience can be interpreted and understood.

Janis Phelps on training the first psychedelic therapists

Professor Janis Phelps PhD
Janis Phelps is the founder and director of the CIIS Center for Psychedelic Therapies and Research, which conducts the first academically accredited, professional certificate training programme for psychedelic-assisted therapy and research. 
At ICPR 2020, Dr. Phelps will address her experience in setting up a licensed training program for people working in research and therapy with psychedelics. 

You founded the first licensed training program for psychedelic therapists. How did this come about ?
The genesis of this program came about in 2014 at a Heffter Research Institute board meeting, where one of the trustees of our college heard the dire need for psychedelic therapists to be trained.
Our university has been training about 250 therapists a year in 6 different programmes for over 30 years. Stan Grof, Ralph Metzner and other psychedelic researchers have been teaching at CIIS for decades. CIIS trustees gave us seed money for a 3-year grant. I was the founder and creator of the programme, and the opportunities for this were very rich.
We wanted to bring in indigenous ways of knowing as well as the approach typically used in the research protocols for both psilocybin and MDMA.
What are the challenges you faced in this process ?
Well, we were creating something in a vacuum. There were no guidelines yet for how to do this, because no-one had done it before. For a year, I consulted with researchers, underground and above-ground therapists, and in related areas such as hospice care centres and emergency rooms, on how to work with people in altered states.
To devise the programme, we drew from anthropology, clinical and transpersonal psychology, psychoanalysis and ceremonial uses. The challenge was to try to integrate all these in the best possible way.
However, we chose to emphasise the research approach for now, because of the need for therapists to be in FDA-approved clinics. This is a compromise we made, but the upside is that now our graduates get hired by these research entities and they’re opening clinics that will be ready to use MDMA and psilocybin in the next couple of years.
Things seem to be progressing quite fast these days. Are you sometimes concerned they may be going too fast?
I’m concerned about the decriminalisation movements in the US. They’re going quicker than I’m comfortable with. The general public is not sufficiently aware of the hazards and the benefits of the use of plant medicines. Even physicians and nurses don’t know enough, and neither do school teachers.
So we’re working on scaling up our programme to include the general public and give them information online for free: interactions with medications, incompatibilities with certain psychological difficulties, how parents can talk to their kids about psychedelics, etc. I’m concerned there might be another backlash like we had in the sixties if these medicines are not used responsibly.
My other concern is that we’re training only 75 people a year, about 300 so far. MAPS has only trained about 250. We need thousands of therapists trained. I’m concerned that when the medicines get rescheduled, there won’t be enough therapists, with resulting insufficient access to the medicines for patients. So we’re looking to scale it up and develop affiliations with other universities.
What have you taken away from this whole adventure so far?
I’ve been delighted to witness the integrity of the therapists and medical doctors wanting to come into this space. They want to see healing happen, they’re concerned about what’s happening on the planet in terms of politics, genocides and global warming.
They know that psychedelics are not the only way for people to heal, of course, but the kind of therapy we can do is augmented tremendously by the use of plant medicines. I see them changing psychiatry and psychology for nothing but the good.
On average, the professionals who apply for the programme have 15 years of licensed practice, so they’re quite experienced in their work. Some were retired medical doctors who reactivated their license in order to do this work. I also witnessed our students building community with each other, creating associations, building salons, and it’s very exciting to see this flourish across the United States, into Canada, South America and the EU. I realised once again how desperate people are for community. And finally, it’s been wonderful to meet the new generation, I’m very happy to pass the hat to younger people.
Dr. Phelps’ talk at ICPR 2020 will be titled: “Training future psychedelic therapists

The biggest challenges for psychedelic science today

Over the last decade, psychedelics have made a comeback in the world of research and academia. As they enter into a new phase of clinical trials, they bear the promise of improving people’s well-being by reducing their depression and anxiety, helping them overcome addiction, or even helping them cope with death and bereavement. This has caused a wave of new publicity, acceptance, and enthusiasm around psychedelic science.
Given that this area of research has been taboo for many decades, there is reason to be optimistic. There is an amount of new data coming in from numerous new clinical trials across various patient groups. As we anticipate the results of these investigations, it is equally important to remain critical, however, in order to ensure that this newly found enthusiasm does not reinstate the myth of the magic bullet that will ultimately cure all our mental ailments.
As research is being conducted in ever more places, some key challenges for the field are also becoming apparent. This piece wants to address those scientific issues as psychedelic science moves forward.
Science in Crisis
The scientific study of psychedelics is not immune from broader crises that are currently ongoing in the scientific realm, like the replication crisis, the lack of Open Science practices and the increasingly privatized funding of research.
The replication crisis comes from research that has shown that many results across different scientific studies cannot be reproduced. This has sometimes led to questionable research practices, such as modifying the results, fabricating data, or selective reporting of false positive findings, by individual actors. Prior hypotheses most often do not yield positive results, and researchers are often faced with unexpected findings.
Publishing these chance findings becomes problematic if the researchers do not clearly demarcate them as such, and conceal the failure of the initial hypothesis and post-hoc explanation of their findings. According to a meta-analysis conducted by Daniela Fanelli (2009), up to 72% of all scientists admit to witnessing questionable research practices concerning the behavior of their colleagues. Misconduct was reported most frequently in the areas of medical and pharmacological research, hence the area of psychedelic research is likely to be implicated. This is something to be acutely aware of.
Positivity bias
Many researchers in the field are understandably psychedelic enthusiasts. This bears a significant risk of selective reporting and motivated reasoning. The promise of psychedelics shown in clinical trials has already led to a nearly one-sided emphasis on the positive effects in the scientific literature, while ignoring the potentially adverse consequences such as mystic ego inflation, neuroticism, or the potential to induce false memories.
Combined with the earlier mentioned broader current problems in science, these over-positive tendencies are incentivized on a community-wide level due to a strong bias towards publishing positive findings, while the negative results are left unpublished in a file drawer.
This problem may be especially pertinent given the relatively high costs and investments involved in conducting psychedelic research, thereby creating a strong incentive for publishing positive results. And what may further limit the researcher’s degree of freedom, is that most studies on psychedelics are sponsored by private foundations with a vested interest.

Open Science practices
Many of these issues can be addressed by adhering to the guidelines of the Open Science Framework. This includes the preregistration of all hypotheses, the study design, data collection methods, and analysis pipelines to increase transparency throughout every step of the scientific process.
Many journals even offer the opportunity of depositing a research question and study design with a registration service or journal before conducting a scientific investigation. Future studies in the domain of psychedelic research would do well by making use of these practices in order to increase the credibility of their findings, and devote extra energy towards replicating some of the existing results via independent research groups.
Placebo-problem
The altered states resulting from psychedelics differ so profoundly from other substances, that there is an ongoing search for a good placebo. In a study of mystical experiences, methylphenidate hydrochloride (Ritalin) was used as a placebo (Griffiths, Richards, Mccann, & Jesse, 2006), in studies of psilocybin to treat anxiety in advanced stage cancer patients, niacin (vitamin B3, which produces flushing) was used as a placebo. And in a study of ayahuasca as treatment for depression researchers used zinc sulfate as a placebo, which may induce nausea and vomiting, playing into one of the commonly expected side effects of the hallucinogenic brew. (de Fontes, 2017).
Even within the classical pharmacological research framework for antidepressants, participants could often guess their test condition – which is known as ‘breaking blind’. This boosts the risk of reporting positively on their perceived mental state due to social desirability.
Psychedelic research is particularly prone to these dangers given the profound changes of subjective experiences, which cannot be easily mimicked with active placebos. This inherent risk will always beg the critical question if the subjective effects of psychedelics are determined by social desirability, prior expectations, or suggestibility of the participants.
Current research has partially addressed the placebo-problem by using different dose ranges. For instance, a microdose, minidose, and full-dose within the same cohort. However, the contrasting method of cognitive science and neuroimaging techniques itself, may be a source of ambiguity when interpreting modern day findings.
Comparing Altered States
On a fundamental level there is still a critical gap between an empiric understanding around altered states of consciousness, their underlying mechanisms and their application within clinical practice. We don’t know yet how the effects of psychedelics compare to other methods that have been used to induce altered states of consciousness, such as meditation, sensory deprivation, or breathing exercises. And we’re not good at measuring them.
The renowned theory of decreased Default Mode Network connectivity in response to psychedelics, may also have been driven by the effects of the placebo condition. Extreme boredom and mind wandering are associated with heightened activity of the Default Mode Network, which may create an exaggerated impression that psychedelics decrease the activity whereas in fact the placebo condition is increasing it.
Only relying on these types of contrasts may create a one-sided impression that Default Mode Network activity and ego-dissolution are primary mechanisms of action in psychedelics, while disregarding subjective accounts of indigenous ayahuasca practices wherein the ego remains intact.
Future research should address these nuances and develop more elaborate or diverse blinding methods, while an even more effective line of research could focus on comparing psychedelics to altered states across the full diversity of conscious experience.
This way, researchers may draw more elaborate conclusions by comparing the commonalities and differences between the neurophenomenology of different induction methods.
Systematic Bias
Like any other field, psychedelic research is not exempt from systematic biases that stem from cultural or socioeconomic differences amongst their respective participants. In the field of psychology, this problem is also known as the W.E.I.R.D bias: the majority of all participants are recruited from Western, Educated, Industrialized, Rich, and Democratic societies.
Given that tribal cultures compared to people from WEIRD populations exhibit significant differences in the most paradigmatic examples of psychology (such as the Müller-Lyer illusion), the subjective experience of psychedelics may be equally contingent on cultural differences.
In the area of clinical research, it is likewise important to represent a diverse sample of society that includes members of marginalized cultures or economic status, or risk inheriting biases that are systemic to society.
And while the contextual effects of set and setting are widely acknowledged within the psychedelic research community, future studies should aim to validate their underlying mechanisms in a cross-cultural manner.
The way forward
Much of the research on psychedelics has focused on extreme cases to make psychedelics more politically acceptable for research, like getting psilocybin approved for a study of terminally ill patients, and treating patients who are suffering from treatment-resistant depression. This has created large-scale clinical samples of patients where the etiology of their mental disorders is not represented in a fine-grained manner.
While it is important to test the efficacy of psychedelics on a large scale, it is equally important to maintain a fine-grained perspective as we investigate these substances in a stratified manner. These incremental advancements may require patience and a healthy dose of criticism.
In the long run, it may not only advance the research of psychedelics but elevate the quality of research beyond the caveats and systematic biases of their scientific domain.

Do psychedelics make you more creative?


Creativity and psychedelics have been closely allied ever since recorded history began. We can find ancient mushroom art that was likely inspired by the psychedelic experience, and in more recent history, we have reports of inspiration from psychedelics abound from the Beatles to Steve Jobs to microdosing tech enthusiasts. 
James Fadiman (one of the speakers at ICPR) studied creativity with engineers and architects in the 1960s. Although the studies [1] weren’t up to today’s standards of double-blind, placebo-controlled, they did provide a first hint of what was to come.
The participants noted that they found solutions to problems they had been working on for months. In the studies they were given a moderately high dose of LSD or mescaline (100ug and 200mg respectively). Their inhibitions were reduced, ideation flowed more easily, and they could see the problem from different perspectives.
“Looking at the same problem with (psychedelic) materials, I was able to consider it in a much more basic way, because I could form and keep in mind a much broader picture.” – study participant
Creativity itself is a tricky concept to define and measure. It can be defined as the ability to produce original and unusual ideas, or to make something new or imaginative. You can see creativity as a process that happens by combining information in new ways. This process is most commonly divided into two parts: divergent (generating ideas) and convergent (evaluating ideas) creativity.
Ben Sessa asked in 2008 if it was time to revisit psychedelics and creativity [2], as the creative process and the psychedelic experience shared many characteristics. But that since the 1960s, not many studies had looked into psychedelics and creativity.

Findings

Since 2008 there have been many studies on both the perceived effects (at macro- and microdoses) of psychedelics on creativity. A preliminary conclusion could be that psychedelics help with divergent creativity during the psychedelic experience, and possibly with convergent creativity during the integration afterward. A small selection of them found the following:
During a psychedelic experience with Ayahuasca, divergent creativity was slightly enhanced on one measure [3]. Participants in the study were more creative in identifying novel connections between pictures (PCT test).  Measuring one [4] and two [5] days after a psychedelic retreat with respectively a macrodose of psilocybin and ayahuasca, divergent creativity was also found to be enhanced.
In the study of the psilocybin retreat [4] however, the convergent creativity was impaired during the psychedelic experience. In the test they were worse at identifying a set connection between pictures. But convergent creativity was higher when they measured it seven days later. So although this measure of creativity was worse during a macrodose, it seemed to have improved a week later.
At the microdosing level, many people report being more creative. A survey study that included a test of creativity, on which Rotem Petranker worked, confirmed this [6]. The study found a weak correlation (r = 0.15) between microdosing and creativity.
How psychedelics lead to creativity is still being studied and Ido Hartogsohn points towards the meaning-enhancing properties of them as a possible mechanism [7]. If you’re not as critical of yourself, he states, then you might have more divergent ideas which can then be valuable after evaluation (convergent).
“By magnifying the perceived significance of creative challenges and insights, psychedelics provide users with the impetus to pursue new, less obvious lines of ideation that they might otherwise have ignored; and with enhanced motivation to explore new creative directions to their fullest ramifications.” (p. 129)

Chemistry 

How this happens at the level of brain chemistry is currently being investigated by researchers like Leor Roseman. One study [8] he worked on showed more general coherence and lower frontoparietal network activity whilst on a macrodose of psilocybin.
 


 
The coming decades will shed more light on what aspects of creativity psychedelics can influence. Retreats that work together with researchers, like the one Daan Keiman runs, may help provide insights.
The speakers above are among the 60+ speakers at the Interdisciplinary Conference on Psychedelics Research – taking place from the 24th to the 27th of September. Here, top researchers will showcase the latest multi-disciplinary insights from psychedelic science. More information at icpr2020.net.

Is MDMA a psychedelic?

In conversation with Rick Doblin and Torsten Passie

Is MDMA a psychedelic or not? And what makes it so well suited for therapy? In this conversation between Rick Doblin, Torsten Passie and Joost Breeksema, the use of MDMA in a therapeutic setting is discussed in-depth.

According to Doblin, MDMA’s potential for healing PTSD-patients differs from the ‘classic’ psychedelics, which usually need a mystical experience or something similar to ego-dissolution in order to show similar results as MDMA. With MDMA, patients feel a sense of safety approaching their trauma ‘with their ego intact’, as Doblin puts it.
Then again, Doblin prefers to use the term broadly, and includes breath-working techniques and dreaming as psychedelic. In this conversation, both guests dive into the intricacies of MDMA therapy. According to both experts, MDMA can be seen as part of psychedelics if the term is used broadly.
Rick Doblin has dedicated his life to making therapeutic MDMA a reality. Ever since 1986, his non-profit association called MAPS has been instrumental in advancing the science of psychedelics and MDMA in particular. Their research into the application of MDMA in therapy received Breakthrough Status from the FDA and he is now in phase 2 and 3 of clinical studies with MDMA-assisted psychotherapy in both Europe and the United States.
Torsten Passie is a Visiting Professor at Harvard Medical School (Boston, USA). His extensive research at Hannover Medical School covers the psycho-physiology of altered states of consciousness and their healing potential, including clinical research with hallucinogenic drugs (cannabis, ketamin, nitrous oxide, MDMA, psilocybin). He is an internationally known expert on altered states of consciousness and the pharmacology of hallucinogenic drugs. He talks about the intricacies of psychedelic therapy, medicalization and how to integrate psychedelics into mainstream health care.
Both Torsten and Rick will present at ICPR 2020, and we’ll have panels on all these topics. A preview of what is to come in this conversation.

Chemical Composition of Traditional and Analog Ayahuasca

Abstract

Traditional ayahuasca can be defined as a brew made from Amazonian vine Banisteriopsis caapi and Amazonian admixture plants. Ayahuasca is used by indigenous groups in Amazonia, as a sacrament in syncretic Brazilian religions, and in healing and spiritual ceremonies internationally. The study aimed to determine concentrations of the main bio- and psychoactive components of ayahuasca used in different locations and traditions. We collected 102 samples of brews from ayahuasca-using communities. Concentrations of N,N-dimethyltryptamine (DMT), tetrahydroharmine, harmine, and harmaline were determined by ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS). Qualitative analyses for non-traditional additives (moclobemide, psilocin, yuremamine) were performed by high resolution mass spectrometry. Higher and more variable concentrations of DMT in neoshamanic ayahuasca samples compared to indigenous samples may indicate use of higher and more variable proportions of DMT-containing admixture plants. From European samples, we found two related samples of analog ayahuasca containing moclobemide, psilocin, DMT, yuremamine, and very low concentrations of B. caapi alkaloids. Some analogs of ayahuasca (Peganum harmala, Mimosa tenuiflora) were used in Europe. No analogs were found from Brazil or Santo Daime ceremonies in Europe. We recommend awareness about the constituents of the brew and ethical self-regulation among practitioners of ayahuasca ceremonies.

Positive effects of psychedelics on depression and wellbeing scores in individuals reporting an eating disorder

Abstract

Purpose: Psychedelic therapy is showing promise for a broad range of mental health conditions, indicative of a transdiagnostic action. While the efficacy of symptom-focused treatments for eating disorders (EDs) is limited, improved mental health and psychological wellbeing are thought to contribute to greater treatment outcomes. This study provides the first quantitative exploration of the psychological effects of psychedelics in those reporting an ED diagnosis.

Methods: Prospective, online data were collected from individuals planning to take a psychedelic drug. Twenty-eight participants reporting a lifetime ED diagnosis completed measures of depressive symptomology (Quick Inventory of Depressive Symptomology; QIDS-SR16) and psychological wellbeing (Warwick-Edinburgh Mental Wellbeing Scale; WEMWBS) 1-2 weeks before, and 2 weeks after a psychedelic experience. Twenty-seven of these participants also completed a measure of emotional breakthrough [Emotional Breakthrough Inventory (EBI)] in relation to the acute psychedelic experience.

Results: Bayesian t tests demonstrated overwhelming evidence for improvements in depression and wellbeing scores following the psychedelic experience. Marginal evidence was also found for a correlation between emotional breakthrough and the relevant mental health improvements.

Conclusion: These findings provide supportive evidence for positive psychological aftereffects of a psychedelic experience that are relevant to the treatment of EDs. It is hoped that this will encourage further research and will bolster initiatives to directly examine the safety and efficacy of psychedelic assisted therapy as a treatment of EDs in future clinical trials.

Level of evidence: Level III, cohort study.

Total Recall: Lateral Habenula and Psychedelics in the Study of Depression and Comorbid Brain Disorders

Abstract

Depression impacts the lives and daily activities of millions globally. Research into the neurobiology of lateral habenula circuitry and the use of psychedelics for treating depressive states has emerged in the last decade as new directions to devise interventional strategies and therapies. Several clinical trials using deep brain stimulation of the habenula, or using ketamine, and psychedelics that target the serotonergic system such as psilocybin are also underway. The promising early results in these fields require cautious optimism as further evidence from experiments conducted in animal systems in ecologically relevant settings, and a larger number of human studies with improved spatiotemporal neuroimaging, accumulates. Designing optimal methods of intervention will also be aided by an improvement in our understanding of the common genetic and molecular factors underlying disorders comorbid with depression, as well as the characterization of psychedelic-induced changes at a molecular level. Advances in the use of cerebral organoids offers a new approach for rapid progress towards these goals. Here, we review developments in these fast-moving areas of research and discuss potential future directions.

Psilocybin as a New Approach to Treat Depression and Anxiety in the Context of Life-Threatening Diseases-A Systematic Review and Meta-Analysis of Clinical Trials

Abstract

Psilocybin is a naturally occurring tryptamine known for its psychedelic properties. Recent research indicates that psilocybin may constitute a valid approach to treat depression and anxiety associated to life-threatening diseases. The aim of this work was to perform a systematic review with meta-analysis of clinical trials to assess the therapeutic effects and safety of psilocybin on those medical conditions. The Beck Depression Inventory (BDI) was used to measure the effects in depression and the State-Trait Anxiety Inventory (STAI) was used to measure the effects in anxiety. For BDI, 11 effect sizes were considered (92 patients) and the intervention group was significantly favored (WMD = -4.589; 95% CI = -4.207 to -0.971; p-value = 0.002). For STAI-Trait, 11 effect sizes were considered (92 patients), being the intervention group significantly favored when compared to the control group (WMD = -5.906; 95% CI = -7.852 to -3.960; p-value ˂ 0.001). For STAI-State, 9 effect sizes were considered (41 patients) and the intervention group was significantly favored (WMD = -6.032; 95% CI = -8.900 to -3.164; p-value ˂ 0.001). The obtained results are promising and emphasize the importance of psilocybin translational research in the management of symptoms of depression and anxiety, since the compound may be effective in reducing symptoms of depression and anxiety in conditions that are either resistant to conventional pharmacotherapy or for which pharmacologic treatment is not yet approved. Moreover, it may be also relevant for first-line treatment, given its safety.

Remembering Jordi Riba – Pioneering ayahuasca researcher


We are deeply saddened by the loss of pharmacologist dr. Jordi Riba, probably the most prominent psychedelic researcher in Catalunya and Spain, and a true pioneer in the biomedical study of ayahuasca.
Jordi was a true explorer who conducted his scientific quest for discovery and information in the same way 15th-century discoverers explored territories on unknown continents: without navigation, but with great dedication and perseverance. He became intrigued by the effects of ayahuasca at a time when research into psychedelics was ignored by most of the scientific community, and actively opposed by governments in many countries. Despite these obstacles, he managed to bring ayahuasca to his Barcelona research clinic and published an unprecedented controlled, dose-ranging study on freeze-dried ayahuasca almost 20 years ago. Since then he has published close to 40 scientific research papers on ayahuasca, greatly advancing psychedelic research and significantly contributing to the re-emerging interest in therapeutic applications of psychedelics.
Jordi Riba was a prominent speaker at all previous editions of ICPR. The first time OPEN met with Jordi was in 2010, right before the Mind Altering Science conference. It was the first conference OPEN had ever organized. As novices in this field, we invited several experts, and to our own amazement, many of them, including Jordi, accepted our invitation. We even managed to find a hotel that would accommodate our speakers for free. Jordi Riba and his colleague José Carlos Bouso were the first to arrive in Amsterdam, and they headed directly to the hotel. Before long, they called us and stated politely but in no uncertain terms that thank you very much, we will not be staying here. Flabbergasted, we apologized and tried frantically to find an alternative hotel. Inexperienced as we were, we had not visited the hotel before accepting their offer, but sure enough, the “Hemp Hotel” was aimed at cannabis tourists; the shabby couches in the lobby were full of stoned tourists, the hemp smoke thick enough to cut with a knife, and the receptionist absolutely clueless that the hotel was reserved for our speakers. Luckily, we found them a decent hotel and by all accounts, the conference was a success. This anecdote was typical for Jordi – a polite and serious gentleman researcher from Spain who would not abide crappy hotels. He would go on to speak at all of our conferences throughout the years, and would have been present at ICPR 2020, had circumstances been different.
Looking back on fifteen years of ayahuasca research in an interview with OPEN, he shared many of the complexities – technically, culturally, and pharmacologically – of studying such a culturally embedded and variable plant mixture. To address some of these, he managed to create standardized, freeze-dried and encapsulated ayahuasca, which he administered to volunteers in various doses in his Barcelona lab. In addition to the pharmacodynamics and pharmacokinetics of ayahuasca, he used neuroimaging techniques to study the brew’s effects on humans, and used in vitro techniques to investigate the effects on a cellular level. At his last lecture at ICPR 2016, he presented ground-breaking findings, showing that the harmala alkaloids, harmine and tetrahydroharmine, induce neurogenesis, which not only provided further evidence that ayahuasca’s effects were due to more than just DMT, made available orally, but that the beta-carbolines present in the brew had important, therapeutically relevant effects of their own. It is unfortunate that throughout most of his career he conducted his research without much scientific support or resources while overall recognition of his work only emerged towards the end of his career. But Jordi accepted irony easily and embraced satire, as he was a man full of wit and humour. It’s quite telling that Don Quixote was among his favourite novels.
During the final years of his career Jordi resigned from Sant Pau Hospital while facing an existential crisis. He felt very lucky to be surrounded by warm-hearted family, friends and colleagues and had every intention to find his way back to academia. He loved the free haven of questioning and exploring minds, driven by curiosity, without prejudice, bias or agenda. Jordi Riba’s passing was sudden and tragic, and we can only remember his curiosity, scientific diligence and wry sense of humor with fondness. He will be sorely missed.
