Several trials of psilocybin for symptoms of depression have shown encouraging findings, as have a number of systematic reviews and meta-analyses. However, several of the reviews have included nonrandomized trials and studies in which psilocybin was used in conjunction with psychotherapeutic interventions, making it difficult to isolate psilocybin's effects...
BACKGROUND: Voter initiatives in Oregon and Colorado authorize legal frameworks for supervised psilocybin services, but no measures monitor safety or outcomes. AIMS: To develop core measures of best practices. METHODS: A three-phase e-Delphi process recruited 36 experts with 5 or more years' experience facilitating psilocybin experiences in various contexts ...
Introduction: Psilocybin is a naturally occurring tryptamine derivative psychedelic compound potently produced by fungi members of the genus Psilocybe. Previous literature has highlighted psilocybin as a serotonin 2A receptor agonist with striking effects on neural plasticity and cognition. Recent studies explore the usage of psilocybin in addressing addicti...
Background and Purpose Demand for new antidepressants has resulted in a re-evaluation of the therapeutic potential of psychedelic drugs. Several tryptamines found in psilocybin-containing “magic” mushrooms share chemical similarities with psilocybin. Early work suggests they may share biological targets. However, few studies have explored their pharmacologic...
BACKGROUND AND AIMS: Lysergic acid diethylamide (LSD) and psilocybin are used as recreational drugs, and there is renewed interest in their clinical use. The current study aimed to (1) determine the circumstances of death and case characteristics of LSD- and psilocybin-related death in Australia, 2000-23; and (2) determine the toxicological profile and major...
Psilocybin is gaining popularity as research shows potential benefits to those with anxiety, depression, and other mental health conditions. Individuals with risk factors for psychosis are typically excluded from such studies, limiting the empiric research of the risks and benefits in vulnerable populations. In the real-world setting, many individuals who se...
In vivo, psilocybin is rapidly dephosphorylated to psilocin which induces psychedelic effects by interacting with the 5-HT2A receptor. Psilocin primarily undergoes glucuronidation or conversion to 4-hydroxyindole-3-acetic acid (4-HIAA). Herein, we investigated psilocybin’s metabolic pathways in vitro and in vivo, conducting a thorough analysis of the enzymes...
BACKGROUND: Psilocybin offers new hope for treating mood disorders due to its rapid and sustained antidepressant effects, as standard medications require weeks or months to exert their effects. However, the mechanisms underlying this action of psilocybin have not been identified. AIMS: To investigate whether psilocybin has rapid and sustained antidepressant-...
Psilocybin has shown promise for alleviating symptoms of depression and is currently in clinical trials for the treatment of anorexia nervosa (AN), a condition that is characterised by persistent cognitive inflexibility. Considering that enhanced cognitive flexibility after psilocybin treatment is reported to occur in individuals with depression, it is plaus...
Background: Immediate early genes (IEGs) are rapidly activated and initiate diverse cellular processes including neuroplasticity. We report the effect of psilocybin (PSIL), PSIL-containing psychedelic mushroom extract (PME) and 5-hydroxytryptophan (5-HTP) on expression of the IEGs, cfos, egr1, and egr2 in mouse somatosensory cortex (SSC). Methods: In our ini...
Psilocybin, and its metabolite psilocin, induces psychedelic effects through activation of the 5-HT2A receptor. Psilocybin has been proposed as a treatment for depression and anxiety but sometimes induces anxiety in humans. An understanding of mechanisms underlying the anxiety response will help to better develop therapeutic prospects of psychedelics. In the...
Introduction: Psilocybin, a tryptamine psychedelic, has been touted in the media both historically and recently as a potential game-changing mental health therapeutic. ClinicalTrials.gov has over one hundred and thirty psilocybin clinical trials listed covering the last twenty years. The single most important aspect of any therapeutic is to gain approval for...

BACKGROUND: There is growing evidence for the therapeutic effects of the psychedelic drug psilocybin for major depression. However, due to the lack of safety data on combining psilocybin with selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) and concerns that there may be a negative interaction on effica...
A single 25-mg dose of psilocybin resulted in improvement in depressive symptoms in all 15 participants in an open-label nonrandomized trial enrolling adults with bipolar II disorder. Twelve of the 15 participants met response and remission criteria at the study's 12-week endpoint.
BACKGROUND: The primary psychoactive drug in magic mushrooms, psilocybin, induces profound alterations in consciousness through the 5-HT2A receptor. This review consolidates current research findings to elucidate the pharmacology, safety profile, and clinical applications of psilocybin. AREAS OF UNCERTAINTY: Despite initial concerns that psilocybin could cau...
Background: Psilocybin is a psychedelic drug with potential therapeutic effects in patients with mood and substance use disorders. Little is known about its impact on the immune system. Methods: Multiplex immunoassay pro-inflammatory cytokine panels (Meso-Scale Discovery, Rockville, MD) were used to examine the serum from participants in three separate rando...
