Psilocin is the active metabolite of psilocybin a natural material found in several types of fungi. The bioavailability of psilocybin, the prodrug of psilocin, has been reported to be over 60%. However, pharmacokinetics and bioavailability of psilocin mucate has not been reported. This Phase I "First in Man" study of psilocin mucate is designed to determine ...
Hallucinogenic mushrooms have been used in religious and cultural ceremonies for centuries. Of late, psilocybin, the psychoactive compound in hallucinogenic mushrooms, has received increased public interest as a novel drug for treating mood and substance use disorders (SUDs). In addition, in recent years, some states in the United States have legalized psilo...
Importance: Psilocybin shows promise as a treatment for major depressive disorder (MDD). Objective: To evaluate the magnitude, timing, and durability of antidepressant effects and safety of a single dose of psilocybin in patients with MDD. Design, Setting, and Participants: In this phase 2 trial conducted between December 2019 and June 2022 at 11 research si...
There has been a resurgence of interest in the use of psychedelic therapies for several mental and substance use disorders. Psilocybin, a "classic" serotonergic psychedelic, has emerged as one of the primary compounds of interest in clinical research. While research on psilocybin's potential mental health benefits has grown, data on the safety and efficacy o...
Introduction: There is substantial public interest in psychedelics as potential treatments for psychiatric conditions. However, most psychedelics are criminalized under federal law in the USA, so it is unclear whether use occurs with clinical support. Our objective was to assess whether naturalistic psychedelic use occurs with clinical support, interactions ...
This review aims at RCT's of psychedelics used in the treatment of depression and PTSD. Psilocybin has shown an antidepressant effect in cancer patients that was sustained at 6- and 12-months follow-up. The effect of psilocybin was comparable to escitalopram in one study. Ketamine has shown effect for the treatment of resistant depression. Phase 2 and 3 tria...
Psilocybin is being investigated as a treatment in adults with treatment-resistant depression (TRD). Withdrawal from serotonergic antidepressant drugs is a common prerequisite for taking part in trials of psilocybin due to the possibility of ongoing antidepressant drugs altering the psychedelic effect. This phase II, exploratory, international, fixed-dose, o...
This work is a literature review on the use of psilocybin in psychotherapeutic treatment of mental illnesses. The review answers the question of what opportunities and risks are associated with the use of the psychoactive substance psilocybin. Peer-reviewed studies between 2017 and 2022 were included. Nine studies were found regarding the following indicatio...

BACKGROUND: Randomised controlled trials (RCTs) of psilocybin have reported large antidepressant effects in adults with major depressive disorder and treatment-resistant depression (TRD). Given psilocybin's psychedelic effects, all published studies have included psychological support. These effects depend on serotonin 2A (5-HT2A) receptor activation, which ...
Mood disorders are recurrent/chronic diseases with variable clinical remission rates. Available antidepressants are not effective in all patients and often show a relevant response latency, with a range of adverse events, including weight gain and sexual dysfunction. Novel rapid agents were developed with the aim of overcoming at least in part these issues. ...

Classic psychedelics, lysergic acid diethylamide, psilocybin, mescaline and N,N-dimethyltryptamine, are potent psychoactive substances that have been studied for their physiological and psychological effects. However, our understanding of the potential interactions and outcomes of using these substances are used in combination with other psychoactive drugs i...
BackgroundClassic serotonergic psychedelics have anecdotally been reported to show a characteristic pattern of subacute effects that persist after the acute effects of the substance have subsided. These transient effects, sometimes labeled as the 'psychedelic afterglow', have been suggested to be associated with enhanced effectiveness of psychotherapeutic in...
INTRODUCTION: Psilocybin-assisted therapy has shown significant promise in treating the cluster of mood and anxiety symptoms that comprise post-traumatic stress disorder (PTSD) but has yet to be tested specifically in this condition. Furthermore, current pharmacological and psychotherapeutic treatments for PTSD are difficult to tolerate and limited in effica...
Several studies have been conducted and more are underway examining psilocybin-assisted therapy as a treatment for various psychiatric conditions including depressive disorders, anxiety disorders, and alcohol use disorder. However, many studies have been limited by small sample size and have not comprehensively evaluated treatment risks outside of controlled...
While a relatively large body of research exists on many aspects of psychedelic therapy, articles describing a complete, successful treatment process are rarely found. This article therefore presents a case of a woman in her early forties with early complex trauma due to domestic violence, sexual abuse and poverty in her childhood, resulting in approximately...

Psychedelic-assisted therapy (PAT) may treat various mental health conditions. Despite its promising therapeutic signal across mental health outcomes, less attention is paid on its potential to provide therapeutic benefits across complex medical situations within rehabilitation medicine. Persons with spinal cord injury (SCI) have a high prevalence of treatme...
BACKGROUND: Psychedelics are an increasingly active area of research and pharmaceutical development. This includes abuse potential assessment to better understand their pharmacological mechanisms and effects and guide controlled substance regulation. Psychedelics pose challenges to abuse assessments to ensure valid, reliable, and generalizable outcomes and s...
