The purpose of the present study is to evaluate the feasibility, initial signals of efficacy, and potential mechanisms of action of "microdoses" of psilocybin (i.e., low doses of psilocybin that are not believed to produce mystical-type, transcendent, hallucinogenic, or other overtly salient subjective effects that limit functionality) in the treatment of mo...
The primary purpose of this study is to preliminarily estimate the efficacy of psilocybin-facilitated treatment for fibromyalgia. Investigators will assess the impact of psilocybin-facilitated treatment on pain, fatigue, and other fibromyalgia symptoms, in addition to the level of functioning and quality of life. Investigators will also evaluate potential me...
Abstract Background: This case describes a substance-induced manic episode with psychotic features in which interaction with an AI (artificial intelligence) chatbot appeared to corroborate and reinforce the patient’s delusional thought content and to contradict medical advice. Excerpts from the patient’s interactions with the AI chatbot provide novel clinica...
The goal of this clinical trial is to learn if psilocybin, given with psychological support, is safe and helps treat anorexia nervosa in young adults. Anorexia nervosa is a serious eating disorder that currently has no approved medicine. Psilocybin is a psychedelic substance that may help the brain form new connections, which could make it easier for people ...
Selective serotonin reuptake inhibitors (SSRIs) are widely prescribed for mood and anxiety disorders, the same conditions under which psychedelic-assisted therapies are gaining renewed interest. However, it remains unclear how SSRI treatment may influence sensitivity to psychedelics, particularly through the shared engagement of serotonergic pathways. Here, ...
This article corrects an idea in psychedelic science and culture that the ancient Eleusynian Mysteries used psychedelics, as claimed by Carl Ruck and co-authors in (1978), revitalized by Brian Muraresku's (2020), and popularized by social media heavyweights such as Joe Rogan. It begins by exposing critical methodological flaws in the arguments, namely, a pat...
Psilocybin, a classic psychedelic compound, has garnered renewed interest as a potential treatment for various psychiatric disorders. This review provides a comprehensive overview of psilocybin's history, recent clinical evidence, ongoing clinical trials, neuroimaging findings, and regulations. Historically used in spiritual and healing rituals, psilocybin w...
The aim of this double-blind, placebo-controlled, within-subjects study is to determine whether other psychoactive substances can produce experiences akin to those seen with classic psychedelics. Screening involves a medical and psychiatric examination, including blood draw, history and physical, interviews, and questionnaires. Eligible participants will the...
ABSTRACT This paper examines the intimate relationship of affection, consumption, and ritual practice between humanity and mushrooms of the genus Psilocybe, focusing mainly on the Americas and Brazil. To this end, it uses reflections that present the American continent as a macroregion historically marked by transits, connections, and exchanges since pre-Col...
The goal of this open-label, dose-escalation, prospective study is to evaluate the safety and psychological effects of a Psilocybin and D-Serine formulation in healthy volunteers. The main objectives are: 1. To assess the psychological and physiological effects of psilocybin administered with D-Serine in healthy adults. 2. To determine whether D-Serine modul...
INTRODUCTION: Although commonly used in psychedelic-assisted therapy, the role of therapeutic touch remains loosely defined and ethically sensitive. Gaining insight into how participants experience and interpret touch during psychedelic sessions is essential for informing safe and effective clinical practice. METHODS: Participants were sampled from a large r...
Background: As public and scientific interest in psychedelics grows, unsupervised use for health purposes is increasing. In the U.S., past-year hallucinogen use nearly doubled from 2015 to 2023. Many individuals report self-treating physical or psychological symptoms without medical supervision using psychedelics-a practice termed self-medication. Despite th...

In Paragraph 1 of the “Psilocybin” section, the sentence “Although it is difficult to find archaeological evidence of their use in prehistory, some estimate their use may date as far back as 40 000 years based on cave paintings ...
Psilocybe cubensis mushrooms are typically not consumed for their nutritional value. The main reason people ingest these mushrooms is for their psychoactive effects. Recently, there has been growing interest in the potential therapeutic applications of psilocybin-containing mushrooms in a range of psychiatric conditions, including depression, anxiety disorde...
Psychotic symptoms are uncommon and non-specific adverse effects of classic (serotonergic) psychedelics such as lysergic acid diethylamide (LSD), psilocybin, and mescaline. They can emerge during the acute phase of psychedelic drug effects, persist into the subacute ("afterglow") period, or, in rare cases, develop into long-term psychotic illness. Across all...
Classic psychedelics such as psilocybin, lysergic acid diethylamide (LSD), and 5-methoxy-dimethyltryptamine (5-MeO-DMT) have shown promising effects in the treatment of certain mental health conditions. Enthusiastic claims about their therapeutic potential have led to overly optimistic reactions in the media and the public, subsequently resulting in increase...
Background: Psilocybin has been granted breakthrough therapy status in the United States, speeding its advancement from research to clinical care. Due to the controversial nature of psilocybin, psychiatrists may not be fully prepared to incorporate it into clinical practice. The current study aimed to evaluate the opinions toward psilocybin among practicing ...
Magic mushroom poisoning can be associated with acute kidney injury (AKI), primarily due to ischemic acute tubular necrosis (ATN). Additionally, the use of cocaine can lead to both venous and arterial thrombosis through its vasoconstrictive and prothrombotic effects. In this article, a middle-aged gentleman with a previous history of cocaine use was admitted...
The past two decades have seen the reemergence of research investigating the therapeutic potential of psychedelic drugs across neuropsychiatric illnesses. One condition, alcohol use disorder (AUD), is of relevance given the broad public health implications and both limited effectiveness and attrition associated with currently available treatments. While emer...
In a suburb of Vancouver, Canada, a nondescript three-story building sits alongside a strip of parking lots. From the outside, it looks like an ordinary commercial office space. But inside is something more extraordinary: rows of shelves stacked with plastic tubs full of magic mushrooms-mushrooms that contain the hallucinogenic chemical psilocybin. In a year...
