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...
Introduction: Depression is a widespread mental illness that affects a large portion of the world population and many of those who suffer from depression are resistant to treatment currently available. The purpose of this review is to compare the efficacy of psilocybin to the current available methods for the treatment of refractory depression. Methods: PubM...
Psychedelics are a group of substances within the heterogeneous class of hallucinogenic drugs. Via binding to the serotonin (5-HT) 2A receptor, psychedelics exert profound alterations in various mental domains, including sensation, cognition, emotions, and self-perception. Psychedelics comprise phenethylamines (e.g., mescaline), tryptamines (e.g., psilocybin...
There is a large and rapidly growing body of literature investigating the therapeutic effects of classic psychedelics in affective and anxiety disorders, but very few studies have examined the inverse of this, that is, the potential for psychedelics to inflict anxiety and affective symptoms. A systematic literature search was performed and 39 papers were inc...
Humans have long used classical serotonergic psychedelics, such as psilocybin, for a variety of purposes. Entactogens, such as methylenedioxymethamphetamine (MDMA), emerged during the twentieth century and have likewise seen use in a broad range of settings. Interest has arisen in the use of classical psychedelics and entactogens, together termed "psychedeli...
There remain significant gaps in knowledge about best practices for facilitated psychedelic care and psychedelic-assisted therapy. To inform the development of service models that support safe and beneficial experiences, this qualitative study explored expert perspectives on current and ideal standards of care, including key practices (e.g., screening, adapt...
Classic psychedelics such as LSD, psilocybin, and DMT from unregulated markets pose considerable risks through unknown adulterants and potencies. In this chapter, we explore the importance of drug checking in minimizing harm among users of classic psychedelics and examine the opportunities and challenges associated with intervention settings, analytical tech...
OBJECTIVE: Anxiety is common in patients receiving end-of-life care and significantly impacts their quality of life. However, pharmacological management remains challenging due to complex clinical presentations and potential side effects, emphasizing the need for systematically reviewing existing treatments. Here we aim to systematically evaluate the efficac...
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...
Major depressive disorder (MDD) continues to pose a major therapeutic challenge due to its clinical heterogeneity. This chapter looks at the development of antidepressant treatments, starting with early interventions such as electroconvulsive therapy (ECT), monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants (TCAs). Although these treatments t...
Depression is a complex and globally prevalent mental disorder, for which conventional antidepressant medications face limitations such as delayed onset and insufficient efficacy. Classic psychedelics, most notably psilocybin, have recently emerged as promising candidates for treatment of depression and demonstrated rapid, robust, and sustained antidepressan...
Approximately 15% of pregnant women experience postpartum depression (PPD). Even with currently available antidepressant treatments, many women will continue to be impaired by symptoms. Psychedelic therapy offers a promising transdiagnostic therapeutic strategy for several mental health disorders, and early results from current trials suggest that serotonerg...
The goal of this randomized controlled trial is to evaluate the safety, feasibility, and efficacy of psilocybin assisted therapy as an intervention to reduce symptom burden in adult patients (aged 18-65) with persisting symptoms after concussion (PSaC). This trail will test the following 2 aims: AIM1: To test the safety and feasibility of an active psilocybi...
This trial aims to examine the safety and efficacy of small (2mg) sub-hallucinogenic doses of psilocybin in people with Major Depressive Disorder. This protocol is for a University of Toronto - sponsored, randomized, placebo-controlled crossover phase 2 study of the safety and efficacy of low doses of psilocybin in subjects with depressive symptoms who meet ...
Background: Psilocybin has shown promise in neuropsychiatric disorders but presents a paradoxical relationship with seizures and epilepsy. Methods: A narrative review was conducted up to November 23, 2025. We conducted structured literature searches across PubMed/MEDLINE, Scopus, Web of Science. and Google Scholar using MeSH terms and keywords to identify st...
OBJECTIVE: The goals of this study were to examine the therapeutic effects and safety of psilocybin given as a pulsed regimen for the prevention of migraine and to consider the blinding integrity of an active control agent. BACKGROUND: The administration of a single low dose of psilocybin was observed to have lasting therapeutic effects in one small pilot tr...
This study aims to explore the safety and tolerability of a single dose of psilocybin (25mg) administered under supportive conditions to adult participants with TRD and chronic suicidal ideation
The primary objective of the study is to evaluate the safety and efficacy of psilocybin in adults with major depressive disorder (MDD) and borderline personality disorder (BPD). The primary objective of the proposed study is to evaluate the safety and efficacy of psilocybin in adults with major depressive disorder (MDD) and borderline personality disorder (B...
