The CAnadian Network for Psychedelic-Assisted Cancer Therapy (CAN-PACT) was launched in 2025 to address urgent gaps in supportive care for Canadians with cancer experiencing demoralization syndrome (loss of meaning, dysphoria, disheartenment, helplessness, a sense of failure) and related psychosocial distress. CAN-PACT has six major objectives: (1) to develo...
Novel interventions for post-traumatic stress disorder (PTSD) leverage the psychoactive properties of psychedelic compounds, such as ketamine, 3,4-methylenedioxymethamphetamine and psilocybin, which may overcome limitations of conventional treatments. Through the modulation of pathways involved in synaptic plasticity, psychedelic interventions are believed t...
Background: Psilocybin-assisted psychotherapy (PAP) may be an effective intervention for a range of mental disorders. However, there appears to be a relative lack of qualitative evidence to complement emerging quantitative findings. To our knowledge, no reviews have systematically mapped the literature on qualitative studies on PAP for the treatment of menta...
First-hand experience with psychedelics may help clinicians develop skills and knowledge needed to work with the profound changes to conscious awareness occasioned by psychedelics. However, the topic remains contentious and underexplored. In this world-first study, we investigated the utility of psilocybin experiential therapist training in a sample of 14 me...
The goal of this study is to learn how psychedelics may help symptoms of depression and anxiety. Participants with major depressive disorder experiencing symptoms of depression and anxiety will receive one dose of either a drug related to psilocybin or a placebo. Assessments include interviews, self-report questionnaires, EEG and fMRI to measure symptoms and...
Psilocybin, an indoleamine alkaloid derived from various fungal species, is the subject of renewed, rigorous investigation for its therapeutic potential in psychiatry. This compound, a prodrug for the active metabolite psilocin, functions primarily as a partial agonist at the serotonin 2A (5-HT2A) receptor. Its administration within a structured psychotherap...
Psilocybin has emerged as a promising therapeutic agent for psychiatric and neurological disorders. However, its legal status varies significantly across countries, creating barriers for clinical use and research. This paper provides an international overview of the regulatory landscape governing medical psilocybin, highlighting key legal restrictions, polic...
Psychedelic-assisted therapy (PAT) frequently utilises a “cotherapy” model, in which two therapists jointly support participants or patients through preparation, dosing, and integration sessions. While common in clinical trials, the experience of cotherapy from the participant perspective remains underexplored. This qualitative study examined experiences of ...
BACKGROUND: Depression and burnout, which are common among healthcare workers, were exacerbated by the COVID-19 pandemic. Mindfulness-Based Stress Reduction (MBSR) and psilocybin have been reported to reduce depressive symptoms, but the efficacy of the combination requires comparison to an active treatment control. We sought to evaluate the safety and prelim...
This is an open-label psilocybin-assisted therapy study that will examine the safety and tolerability of psilocybin-assisted therapy in the offspring of genocide survivors with mood and anxiety disorders. The study will also investigate the efficacy of psilocybin-assisted therapy in reducing symptoms such as depression, anxiety and stress, as well as changes...
Abstract Background Major Depressive Disorder (MDD) is a leading cause of disability and economic loss, with high recurrence and treatment resistance. Psilocybin-assisted therapy (PAT) shows promise in reducing depressive symptoms, but long-term effects are unknown. We aimed to determine the long-term safety and efficacy of PAT for MDD over a five-year follo...
Background: Post-traumatic stress disorder (PTSD) is a debilitating condition for which there are few efficacious treatments. Psilocybin is being studied for use in treatment-resistant depression but has not yet been investigated in PTSD. Aims: The trial’s primary outcome was to investigate the safety and tolerability of single-dose psilocybin in participant...
BACKGROUND: The consumption of dried fruiting bodies of Psilocybe cubensis can be traced over centuries, guided by Mesoamerican curanderas, Western medical practitioners, and fungal enthusiasts, all seeking mental wellbeing. There is a notable resurgence in interest both in the fungal biomass and psilocybin, the psychoactive tryptamine, despite the global re...
This study will examine the effect of a single high dose of psilocybin therapy (30 mg) versus a very low dose (1 mg) as an adjunctive therapy to individuals undergoing standard-of-care outpatient buprenorphine treatment for Opioid use disorder (OUD). The participants will have previously undergone buprenorphine induction before. Effects of adjunctive psilocy...
BACKGROUND: Obsessive-compulsive disorder (OCD) is a common and disabling condition. A large proportion of patients fail to respond to first-line treatment with serotonin reuptake inhibitors either selective serotonin reuptake inhibitors (SSRIs) or clomipramine. Preliminary evidence suggests psilocybin, a serotonin receptor agonist, might be efficacious. We ...
Background: Persisting symptoms after concussion is a complex syndrome warranting exploration into further treatment options. Emerging research highlights the potential of classic psychedelics, such as psilocybin, in managing neuropsychiatric conditions and promoting neuroprotection. Case Report: A case is presented of a 22-year-old male intercollegiate athl...
To compare the physiological and psychological effects of psilocin taken orally by pill or sublingually by dissolving a tablet under the tongue to those of psilocybin taken by pill in healthy adults. The primary goal of this study is to compare the physiological and psychological effects of psilocin taken orally by pill or sublingually dissolved under the to...
Background: Despite significant advancements in the treatment of depression, challenges such as inadequate response rates and high placebo effects highlight the need for improved therapies and a deeper understanding of treatment expectations. Patient expectations play a crucial role in treatment outcomes but have not been systematically investigated in the c...

This Phase 2a clinical trial is designed to evaluate the safety, tolerability, and preliminary efficacy of a 3 mg dose of psilocybin oral solution for the treatment of Generalized Anxiety Disorder (GAD). The study consists of three sequential phases: Screening Phase (up to 4 weeks), Open-label Run-in Phase (4 weeks), Double-blind Treatment Phase (4 weeks) Sc...
