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 "psychedelics," for therapeutic purposes in...
Abstract Classic psychedelics like LSD and psilocybin are showing promising effects in treating certain psychiatric disorders. Despite their low toxicity and lack of an addictive potential, in some individuals, psychedelics can be associated with persisting psychological harms. Hallucinogen Persisting Perception Disorder (HPPD) is one of those complications, a rare disorder characterized by...
Background: Obsessive-Compulsive Disorder (OCD) presents significant challenges to individuals mental health, characterized by intrusive thoughts and repetitive maladaptive behaviours. Recent exploration into alternative treatments has spotlighted psychedelics, notably psilocybin, for their potential therapeutic benefits in different psychiatric disorders, including OCD. This case study delves...
ABSTRACT Psilocybe is a genus of mushroom-forming fungi with ecological, ethnomycological, and clinical importance due to psilocybin production by most species. We present five genomes that enable deeper discovery and analysis of the psilocybin gene cluster and increase taxonomic resolution within Psilocybe : Psilocybe semilanceata , Psilocybe gandalfiana nom. prov., Psilocybe caeruleorhiza ,...
Eating disorders (EDs) are a group of debilitating mental illnesses characterized by maladaptive eating behaviors and severe cognitive-emotional dysfunction, directly affecting 1-3% of the population. Standard treatments are not effective in approximately one third of ED cases, representing the need for scientific advancement. There is emerging evidence for the safety and efficacy of...
There is renewed interest in psychedelics, such as psilocybin, as therapies for multiple difficult-to-treat psychiatric disorders. Even though psychedelics can induce highly pleasant or aversive experiences, depending on multiple personal and environmental factors, there is little research into how such experiences impact post-acute mood-altering actions. Here we aimed at offsetting this gap....
Abstract Adolescent depression is a significant public health concern, yet treatment options remain limited, particularly due to age- and sex-related differences in antidepressant efficacy. This study explored the rapid and long-lasting antidepressant-like potential of psilocybin in adolescent Sprague-Dawley rats, examining acute and repeated oral dosing effects while incorporating sex as a...
ALSUntangled reviews alternate and off-label treatments prompted by patient interest. Here, we review psilocybin, a chemical derived from mushrooms and belonging in the category of drugs known as psychedelics. Psilocybin has plausible mechanisms for slowing ALS progression because of its ability to cross the blood brain barrier and effect neurogenesis and inflammation. Currently, there are no...
Abstract The past decade has seen a huge increase in clinical research with psychedelic drugs and 3,4‐methylenedioxymethamphetamine (MDMA), which have revealed great potential for treating mental health conditions. Given this progress in research, as well as the current unmet clinical need of millions of patients, in 2023, the Australian Therapeutic Goods Administration (TGA) approved the use...
Abstract Psilocybin is a psychedelic tryptamine that has emerged as a potential candidate for the treatment of a variety of conditions, including treatment resistant depression and post-traumatic stress disorder. Clinical trials which have assessed the efficacy of psilocybin for these conditions report a rapid and sustained improvement in patient- and clinician-rated depression scores. The...
Treatment with psilocybin differs fundamentally from classic psychopharmacotherapy. Its potentially transdiagnostic, rapid, and sustainable efficacy and its positive effect on further dimensions of mental health beyond the patient's symptoms and psychopathology imply that it may have diseasemodifying and salutogenic mechanisms of action. Psychotherapy accompanied by the administration of...
SUMMARY We quantify cellular- and circuit-resolution neural network dynamics following therapeutically relevant doses of the psychedelic psilocybin. Using chronically implanted Neuropixels probes, we recorded local field potentials (LFP) alongside action potentials from hundreds of neurons spanning infralimbic, prelimbic and cingulate subregions of the medial prefrontal cortex of...
Introduction: Psilocybin, a classical psychedelic, has been rescheduled for use in psilocybin-assisted psychotherapy for treatment-resistant depression in Australia. While evidence for its use is promising, understanding the associated risks is crucial. Accordingly, this review aims to collate adverse event data from psilocybin-assisted psychotherapy clinical trials and evaluate its definition,...
Preliminary research shows the psychedelic psilocybin to be a promising potential treatment for psychiatric illnesses. Recent U.S. government legislation and policy indicate that access to psilocybin, which remains illegal on the federal level despite increasing efforts to decriminalize it at the state and local levels, will be expanded to enable further research into its treatment potential....
Psychedelic compounds, particularly psilocybin and psilocin, have shown significant therapeutic potential in treating neurological and psychiatric disorders. However, their bioavailability, rapid metabolism, and stability challenges have limited their clinical use. This Patent Highlight reviews recent innovations in psychedelic drug delivery systems and the development of psilocin analogs aimed...

This secondary analysis of a randomized clinical trial examines the association between treatment expectancies and the relative efficacy of psilocybin compared with escitalopram for major depressive disorder.
This article analyzes an excerpt from the documentary Les champignons hallucinogènes du Mexique (Hallucinogenic Mushrooms of Mexico), directed in 1964 by Pierre Thévenard under the scientific guidance of Professor Roger Heim, a mycologist and then-director of the National Museum of Natural History. This rarely broadcast film explores the archaeological, historical, ethnographic, biological,...
Psilocybin use has been increasingly popular in the United States, and its use as a novel therapeutic treatment for psychiatric conditions has led to greater public acceptance as a recreational substance. Consequently, clinicians are faced with managing complications and adverse effects associated with psilocybin use. We present three cases seen in a dual diagnosis inpatient psychiatry unit...
Methamphetamine (MA) dependence leads to severe physical and psychological issues. Current treatments, including psychosocial therapies and residential rehabilitation, face limitations such as high relapse rates, cost, and accessibility issues. As a result, there is an urgent need for novel approaches to treat MA dependence that are effective, affordable, and accessible to patients. Psilocybin,...
Importance The psychological morbidity experienced by physicians, advanced practice practitioners (APPs), and nurses from working during the COVID-19 pandemic includes burnout, depression, and posttraumatic stress disorder (PTSD). Objective To investigate whether psilocybin therapy could improve symptoms of depression, burnout, and PTSD in US clinicians who developed these symptoms from...
