It is designed to be a harm reduction manual for all psychedelic users. Don’t expect this guide to cover topics like how to obtain psychedelics, the legality of psychedelics in your region, or the state of psychedelic research. While we accept that the majority of psychedelic use is not done legally, and that the riskiest aspect of psychedelic use is their prohibited status, we cannot advise you on how to safely circumvent the law. This guide will only address the psychological and physiological risks of psychedelic use; we expect you to understand the legal risks yourself, and be aware of your local laws. For more in-depth information about psychedelic history, psychedelic legality, and current research, check out the resources on The Third Wave. First Things First If you are sitting there in your dojo, fistful of mushrooms poised over your open mouth, playlist lined up and blindfold ready – hold your horses, brave adventurer! No one in the history of psychedelic use has ever said “Yeah, my trip was great, but I was just too goddamned prepared.” We highly recommend that you stand up, open up the blinds, and very slowly put the shrooms down. Then read this guide in full, take a few days to make sure this is what you want to do (and that you’re adequately prepared), and then feel free to go on your psychedelic journey. Why, What, And How? Before we’re ready to prepare ourselves for the psychedelic experience itself, it’s important to take a step back and find your own personal answers to a few questions. Why are you doing this? What are you looking for? What substance are you taking? Are you in good health? These questions can’t be ignored if you’re looking for a truly fulfilling and safe experience. Why Are You Taking A Psychedelic? This may seem like an annoying question. But it’s important to go way back in your psychedelic-taking process, and think about what drew you to psychedelics in the first place. Are you looking to answer a profound question? Would you like to explore some aspect of the universe or existence? Or are you purely curious? Are you sure that psychedelics are the right vehicle to achieve this goal? If you don’t know much about psychedelics, or only have a vague idea about what they can do, it’s well worth taking some time to educate yourself. Listen to some podcasts, read a book or two, and familiarize yourself with the effects. Jumping in without really knowing what you’re getting yourself into could be a mistake. If you’re still not sure, maybe you should take a step back and consider alternatives. There are plenty of other approaches you can take to answer big questions, or find out more about yourself. You might be interested in trying out holistic therapies first, to see if your answer can be found without diving into a psychedelic journey. It might also be worthwhile considering microdosing before you take a large dose. Many people find substantial benefits from starting a microdosing protocol, and it can help you ease in to the effects of psychedelics before taking that big dose. The Third Wave offers a microdosing course for those interested in making the most out of a microdosing protocol – and we also offer extensive free resources and a microdosing book that you can explore. But maybe you are still positive that this is what you’re looking for, and nothing will convince you otherwise. If so, that’s great! Time to think about what substance is best for you. What Are You Taking? The term “psychedelic” can be applied to any number of substances. Meaning “soul manifesting,” pretty much anything that alters cognition and perception could be deemed a psychedelic. But for the purposes of this resource, we will focus on substances that will produce a profound altered state for a significant length of time, and that require considerable preparedness for safe responsible use. The “classic” psychedelics include LSD (a synthetic compound), psilocybin mushrooms (also known as magic mushrooms), mescaline (found in psychedelic cacti), and DMT (found in ayahuasca). These are the most commonly used psychedelics, and are also known as “Serotonergic” psychedelics since they work by affecting the neurotransmitter serotonin. Other less well-known psychedelics include ketamine (a synthetic dissociative), ibogaine (found in the Iboga plant), Salvinorin A (found in the plant Salvia divinorum), and MDMA (a synthetic compound, the main component of “ecstasy” pills). There also exists a wide range of chemical analogues to these substances, that often produce similar effects. They are largely unstudied, and their safety profiles are uncertain. We will focus on the psychedelics that are best understood, and those for which we can provide accurate information regarding safety. Here is some brief information on each substance, to help you decide which will be safest and most appropriate for you: LSD This synthetic psychedelic induces a long-lasting psychedelic experience, usually between six to twelve hours in length. The trip is associated with significant changes in perception, and profound shifts in your understanding of the world. It has no physiological risk, and is typically taken at a dose of between 50-100 micrograms. It is commonly found dissolved on blotter paper (“tabs”) or less commonly in liquid form. Analogues such as 1P-LSD are also physiologically safe, but can have slightly different psychological effects. Learn more about LSD here. Psilocybin This naturally occurring psychedelic is found in some species of mushrooms. It induces an experience lasting between four and six hours. The trip produces significant changes to perception, and profound shifts in your understanding of the world. Psilocybin is often said to have a more “earthy” or “warm” feel to it than the synthetic LSD. It has low physiological risk, although some people report nausea after ingesting. It is most commonly taken by eating fresh or dried mushrooms, or making a tea with powdered mushrooms. A typical moderate-high dose is between 2-4g. You can learn more about psilocybin mushrooms here. Mescaline Mescaline is found in some species of cacti, most commonly Peyote and San Pedro. The experience can last between eight and fourteen hours. The trip produces significant changes to perception, and profound shifts in your understanding of the world. Mescaline can induce a body high similar to that of MDMA. Mescaline is physiologically safe, although nausea is often reported at higher doses. It is most commonly ingested by chewing the cactus “buttons,” or by swallowing capsules of dried ground cactus. A typical moderate-high dose is around 200-400mg. Learn more about mescaline here. DMT DMT (dimethyltryptamine) is a naturally-occurring psychedelic found in several plants. It can be smoked in its crystal form to produce a short-lasting but intense experience, or drank as a component of an ancient plant medicine brew (ayahuasca) producing an experience lasting many hours and inducing nausea. No matter what the form of ingestion, its effects include significant changes to perception, and profound shifts in your understanding of the world. A typical moderate-high dose of smoked DMT is 20-50mg. A typical moderate-high dose of ayahuasca is harder to estimate, as preparation methods may vary. Learn more about DMT here. Learn more about ayahuasca here. Ketamine This synthetic compound was originally used as an anaesthetic. It also has significant dissociative qualities that significantly alter perception, and can cause profound shifts in your understanding of the world. The trip can last from forty-five to ninety minutes, and is known for sometimes producing a catatonic state known as a “K-hole” where all sense of stable reality is lost. It is usually snorted, although this method of ingestion can cause damage to the nose and throat over time. A typical dose in this manner is 30-80mg. It can also be ingested orally, in a capsule, for a longer-lasting and less intense experience: a typical dose is 100-300mg in this method. Intramuscular injection is also possible, but this is discouraged. Ketamine is physiologically toxic when used consistently or in high quantities. Dependence can cause damage to the urinary tract. It is also associated with nausea at large doses. Learn more about ketamine here. Ibogaine Found in the Iboga plant, ibogaine is a unique psychedelic producing a long- lasting experience that can last several days. It is almost certainly the most dangerous of these psychedelics, as high doses have been linked with heart failure.

Despite its surging popularity, little is known about the effects of this practice. This research had two aims. First, we attempted to replicate previous findings in the literature regarding the subjective benefits and challenges involved in microdosing. Second, we wanted to examine whether people who microdose test their substances for purity before consumption, and whether approach-intention to microdosing was predictive of more reported benefits. 7,313 people who reported microdosing, from a variety of countries, ages, and other demographics participated in our survey.

A majority of the research during this recent renaissance has surrounded applications of psychedelics in the fields of mental health. Less attention is being focused to other research areas where psychedelics may also prove informative, such as cognition and information processing. A common trend taking place is the act of administering very small doses of psychedelics as a potential cognitive enhancer, called microdosing.

  • Psychedelic Microdosing Benefits and Challenges: an Empirical Codebook
    Anderson et al. Harm Reduction Journal (2019) 16:43 https://doi.org/10.1186/s12954-019-0308-4 RESEARCH Open Access Psychedelic microdosing benefits and challenges: an empirical codebook Thomas Anderson1* , Rotem Petranker2*, Adam Christopher3, Daniel Rosenbaum4, Cory Weissman4, Le-Anh Dinh-Williams5, Katrina Hui4 and Emma Hapke4 Abstract Background: Microdosing psychedelics is the practice of consuming very low, sub-hallucinogenic doses of a psychedelic substance, such as lysergic acid diethylamide (LSD) or psilocybin-containing mushrooms. According to media reports, microdosing has grown in popularity, yet the scientific literature contains minimal research on this practice. There has been limited reporting on adverse events associated with microdosing, and the experiences of microdosers in community samples have not been categorized. Methods: In the present study, we develop a codebook of microdosing benefits and challenges (MDBC) based on the qualitative reports of a real-world sample of 278 microdosers. Results: We describe novel findings, both in terms of beneficial outcomes, such as improved mood (26.6%) and focus (14.8%), and in terms of challenging outcomes, such as physiological discomfort (18.0%) and increased anxiety (6.7%). We also show parallels between benefits and drawbacks and discuss the implications of these results. We probe for substance-dependent differences, finding that psilocybin-only users report the benefits of microdosing were more important than other users report. Conclusions: These mixed-methods results help summarize and frame the experiences reported by an active microdosing community as high-potential avenues for future scientific research. The MDBC taxonomy reported here informs future research, leveraging participant reports to distil the highest-potential intervention targets so research funding can be efficiently allocated.

  • Microdosing Psychedelics: Personality, Mental Health, and Creativity Differences in Microdosers
    Psychopharmacology (2019) 236:731–740 https://doi.org/10.1007/s00213-018-5106-2 ORIGINAL INVESTIGATION Microdosing psychedelics: personality, mental health, and creativity differences in microdosers Thomas Anderson1 & Rotem Petranker2 & Daniel Rosenbaum3 & Cory R. Weissman3,4 & Le-Anh Dinh-Williams5 & Katrina Hui3 & Emma Hapke3,4 & Norman A. S. Farb1 Received: 10 September 2018 /Accepted: 2 November 2018 /Published online: 2 January 2019 # Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract Rationale Microdosing psychedelics—the regular consumption of small amounts of psychedelic substances such as LSD or psilocybin—is a growing trend in popular culture. Recent studies on full-dose psychedelic psychotherapy reveal promising benefits for mental well-being, especially for depression and end-of-life anxiety. While full-dose therapies include perception- distorting properties, microdosing mayprovide complementary clinical benefits using lower-risk, non-hallucinogenic doses. Objectives This pre-registered study aimed to investigate whether microdosing psychedelics is related to differences in person- ality, mental health, and creativity. Methods In this observational study, respondents recruited from online forums self-reported their microdosing behaviors and completed questionnaires concerning dysfunctional attitudes, wisdom, negative emotionality, open-mindedness, and mood. Respondents also performed the Unusual Uses Task to assess their creativity. Results Current and former microdosers scored lower on measures of dysfunctional attitudes (p < 0.001, r = − 0.92) and negative emotionality (p = 0.009, r = − 0.85) and higher on wisdom (p < 0.001, r = 0.88), openmindedness(p = 0.027, r = 0.67), and creativity (p < 0.001, r = 0.15) when compared to non-microdosing controls. Conclusions These findings provide promising initial evidence that warrants controlled experimental research to directly test safety and clinical efficacy.

Welcome. Welcome! I’m really pleased to introduce our Biochemistry and Biophysics Capstone class who, given the enactment of Oregon Measure 109, took on the task of digging through scientific papers to create a non-controversial science-based perspective on psilocybin and the molecular mechanisms behind its actions. We discovered many diverse studies are relevant, so ... rather than going deep into a few studies, we’ve sought to construct a broad overview of key topics in hopes of giving both scientists and the public a window into the fascinating science of psilocybin along with pointers to the literature to allow follow up on topics of interest.

  • Positive Expectations Predict Improved Mental-Health Outcomes Linked To
    www.nature.com/scientificreports OPEN Positive expectations predict improved mental‑health outcomes linked to psychedelic microdosing L. S. Kaertner1*, M. B. Steinborn2, H. Kettner1, M. J. Spriggs1, L. Roseman1, T. Buchborn1, M. Balaet3, C. Timmermann1, D. Erritzoe1 & R. L. Carhart‑Harris1 Psychedelic microdosing describes the ingestion of near‑threshold perceptible doses of classic psychedelic substances. Anecdotal reports and observational studies suggest that microdosing may promote positive mood and well‑being, but recent placebo‑controlled studies failed to fnd compelling evidence for this. The present study collected web‑based mental health and related data using a prospective (before, during and after) design. Individuals planning a weekly microdosing regimen completed surveys at strategic timepoints, spanning a core four‑week test period. Eighty‑ one participants completed the primary study endpoint. Results revealed increased self‑reported psychological well‑being, emotional stability and reductions in state anxiety and depressive symptoms at the four‑week primary endpoint, plus increases in psychological resilience, social connectedness, agreeableness, nature relatedness and aspects of psychological fexibility. However, positive expectancy scores at baseline predicted subsequent improvements in well‑being, suggestive of a signifcant placebo response. This study highlights a role for positive expectancy in predicting positive outcomes following psychedelic microdosing and cautions against zealous inferences on its putative therapeutic value. Classic tryptamine psychedelics are structurally related to the endogenous neurotransmitter serotonin (5-HT; 5-hydroxytryptamine) and induce their distinct psychological and physiological efects mainly through agonism of the 5-HT2A receptor 1,2. In recent years, the phenomenon of psychedelic ‘microdosing’ has seen a signifcant rise in popularity and prevalence in western societies3–5.
