This randomized controlled clinical trial evaluates the effectiveness of psilocybin and psilocybin-assisted cognitive behavioral therapy (CBT) in the management of Major Depressive Disorder (MDD). The study aims to compare the effects of psilocybin-only therapy, CBT, and psilocybin-assisted CBT on depression symptoms, neurochemical markers, inflammatory mark...
BACKGROUND AND AIMS: Psilocybin has emerged as a potential treatment for alcohol use disorder (AUD), but early efficacy data are inconsistent. Depression following alcohol detoxification significantly increases the risk of relapse. This pilot study aimed to evaluate the feasibility, acceptability, and preliminary efficacy of psilocybin-assisted psychotherapy...
OBJECTIVE: Psychedelics are able to trigger highly intense and profound alterations in self-consciousness, perception, affective, and cognitive processes. Indeed, recent studies show that ketamine and psilocybin could be used as fast-acting antidepressants. However, the molecular and neurochemical mechanisms of these psychedelics and their actions at the lev...
This is a feasibility study to examine the use of use of Psilocybin (magic mushrooms) to alleviate pain in chronic neuropathic pain. While theoretical mechanisms demonstrate promise, there is no clinical evidence. This vacuum of clinical evidence has been occupied by a "psychedelic hype bubble" with media communications touting psychedelics as a 'miracle cur...
OBJECTIVE: To compare changes in depression, anxiety, and suicidality symptoms after a single 25 mg oral dose of psilocybin between treatment-resistant depression participants not on antidepressants at screening to participants that discontinued antidepressant medications leading up to receiving psilocybin-assisted psychotherapy (PAP). METHODS: Participants ...
BACKGROUND: Obsessive-compulsive disorder (OCD) is a complex condition marked by persistent distressing thoughts and repetitive behaviours. Despite its prevalence, the mechanisms behind OCD remain elusive, and current treatments are limited. This protocol outlines an investigative study for individuals with OCD, exploring the potential of psilocybin to impro...
BACKGROUND: Posttraumatic stress disorder (PTSD) affects 3.9% of the general population. While massed cognitive processing therapy (CPT) has demonstrated efficacy in treating chronic PTSD, a substantial proportion of patients still continue to meet PTSD criteria after treatment, highlighting the need for novel therapeutic approaches. Preliminary evidence sup...
OBJECTIVE: Unipolar and bipolar depression severely impact millions of individuals worldwide, with a significant subset of cases remaining unresponsive to conventional treatments. Psilocybin-assisted psychotherapy (PAP) has demonstrated therapeutic efficacy; however, the optimal psychotherapeutic approach remains undefined, ranging from unstructured models r...
BACKGROUND: Psilocybin is being investigated as a treatment for a myriad of disorders, including treatment-resistant depression. The main focus has been on positive effects, with little attention paid to negative outcomes, especially in clinical settings. Quantitative methodology limits further exploration of such events and can also miss improvements not ca...

In the contemporary landscape of psychiatric medicine, critical advancements have been noted in the utilization of psychoactive substances such as hallucinogens, 3,4-methylenedioxymethamphetamine (MDMA), and ketamine for the treatment of severe mental health disorders. This review provides a detailed evaluation of these substances, focusing on their mechanis...
BACKGROUND: Major depressive disorder (MDD) is a leading cause of disability worldwide across domains of health and cognition, affecting overall quality of life. Approximately one third of individuals with depression do not fully respond to treatments (e.g., conventional antidepressants, psychotherapy) and alternative strategies are needed. Recent early phas...
Abstract Background The underlying neurobiology of the complex autism phenotype remains obscure, although accumulating evidence implicates the serotonin system and especially the 5HT 2A receptor. However, previous research has largely relied upon association or correlation studies to link differences in serotonin targets to autism. To directly establish that...
Background: To date, few randomized controlled trials of psilocybin with non-directive support exist for obsessive-compulsive disorder (OCD). Results and participant feedback from an interim analysis of an ongoing single-dose trial (NCT03356483) converged on the possibility of administering a higher fixed dose and/or more doses of psilocybin in future trials...
Background: Psychedelics are receiving growing interest among clinical researchers for their effects on mood and cognition. Psilocybin is one of the most widely studied classic psychedelics which has shown good safety and clinical benefit for major depression and substance use disorders. Athletes frequently sustain concussions and often experience myriad sym...
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...
Background: Psilocybin may help treat obsessive-compulsive disorder (OCD). To date, only one open-label study of psilocybin for OCD exists, necessitating further investigation with a randomized controlled design. The neural correlates of psilocybin's effects on OCD have also not been studied. Objectives: This first-of-its-kind trial aims to evaluate the feas...
Background: Several early phase studies have demonstrated that psilocybin-assisted therapy has rapid-acting and persisting antidepressant effects from just one or two doses. However, methodological limitations (e.g., placebo-control, blinding) limit interpretability of the existing literature. Methods: In an exploratory placebo-controlled, within-subject, fi...
BACKGROUND: COMP360 is a proprietary, synthetic formulation of psilocybin being developed for treatment-resistant depression (TRD), a burdensome, life-threatening illness with high global impact. Here, we expand upon the previous report of primary outcomes from a phase 2 study of COMP360 in individuals with TRD-the largest randomised controlled clinical tria...
