Characteristics and mental health of psychedelic mushroom and multi-psychedelic users relative to non-psychedelic users in American adults, 2020-2021.
Few population-based studies have examined associations between psychedelic use and mental health outcomes. This work describes characteristics of exclusive psychedelic mushroom use (referred to as PM use), PMs in combination with other psychedelic substances (multi-psychedelic or MP) use, and non-psychedelic use and explores mental health ratings in non-cli...
High-quality draft genomes of ecologically and geographically diverse Psilocybe species
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....
Psilocybin-assisted psychotherapy for methamphetamine dependence: a case report involving daily methamphetamine use
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, an...
God hasn’t died, it has merely been encapsulated - Psilocybin and ayahuasca in the psychedelic renaissance: Intersections between religion, indigenous cosmologies, spirituality, and science
This article traces the trajectories of psilocybin and ayahuasca in the context of the psychedelic renaissance. The bibliometric analysis reveals that academic publications on psilocybin fall primarily into the medical and scientific areas, whereas those devoted to ayahuasca derive mainly from humanities and social sciences. Second, the article argues that p...
Psilocybin Fungi Unveiled: Morphological Characteristics and Pharmacological Potentials
Abstract: Psilocybin mushrooms, also known as "magic mushrooms," have garnered significant attention for their psychoactive properties and potential therapeutic applications. This review explores the comprehensive morphology, pharmacognostic properties, and pharmacological activities of psilocybin-producing fungi. The unique morphological characteristics of ...
The Effect of Psilocybe cubensis on Spatial Memory and BDNF Expression in Male Rats Exposed to Chronic Unpredictable Mild Stress
Psilocybin-containing mushrooms, commonly known as magic mushrooms, drastically affect mental processing, cognitive functioning, and the mood state. In the present study, we investigated the effect of the Psilocybe cubensis extract on spatial memory and the brain-derived neurotrophic factor (BDNF) in rats exposed to chronic unpredictable mild stress (CUMS). ...
Structural insights into tryptamine psychedelics: The role of hydroxyl indole ring site in 5-HT2A receptor activation and psychedelic-like activity.
Recent advancements in the study of mushroom-derived tryptamines, particularly psilocybin and its metabolite psilocin, highlight their unique psychedelic properties and potential therapeutic applications, especially for mental health conditions like depression. This study examines how the position of the hydroxyl group on the indole ring affects the 5-HT2A r...
Psilocybin Mushrooms and Public Health in Brazil: Insights from a Retrospective Analysis of Adverse Events and Their Implications for Regulatory Discussions
Current drug policy classifies psilocybin, a compound found in psychoactive mushrooms, as having high abuse potential while overlooking its therapeutic properties. We evaluated the risk of psilocybin mushrooms to Brazilian public health compared to other toxic agents and assessed the need for regulatory discussions. This retrospective cross-sectional study f...
“The mushroom was more alive and vibrant”: Patient reports of synthetic versus organic forms of psilocybin
Abstract Interest in psychedelic research in the West is surging, however, clinical trials have almost exclusively studied synthetic compounds such as MDMA, ketamine, DMT, LSD, ibogaine, and psilocybin. To date, few clinical trials have utilized whole mushroom/plant material like Psilocybe mushrooms, Iboga, or Ayahuasca. Individuals participating in the Root...
Substrate recognition by the 4-hydroxytryptamine kinase PsiK in psilocybin biosynthesis
Psilocybin, the natural hallucinogen from Psilocybe (magic) mushrooms, is a highly promising drug candidate for the treatment of depression and several other mental health conditions. Biosynthesis of psilocybin from the amino acid l-tryptophan involves four strictly sequential modifications. The third of these, ATP-dependent phosphorylation of the intermedia...
The Second Methylation in Psilocybin Biosynthesis Is Enabled by a Hydrogen Bonding Network Extending into the Secondary Sphere Surrounding the Methyltransferase Active Site
Abstract The Psilocybe cubensis SAM-dependent methyltransferase, PsiM, catalyzes the last step in the biosynthesis of psilocybin. Likely evolved from monomethylating RNA methyltransferases, PsiM acquired a key amino acid exchange in the secondary sphere of the active site, M247 N, which is responsible for its capacity to dimethylate. Two variants, PsiM N247M...
Characterization and Identification of an Antimicrobial Compound Psilocybin from Psychedelic Mushroom.
The antimicrobial compound psilocybin possesses psychoactive properties with therapeutic applications. Psilocybin is the main component naturally present in psychedelic mushrooms and has been utilized in the treatment of depression and neurological disorders. In this study, psychedelic mushrooms were collected from Kodaikanal, Tamil Nadu. They underwent solv...
Neuroprotective effects of psilocybin in a rat model of stroke
BACKGROUND: Psilocybin is a psychedelic 5HT2A receptor agonist found in "magic mushrooms". Recent studies have indicated that 5HT2A agonists, such as dimethyltryptamine, given before middle cerebral artery occlusion (MCAo), improve staircase behavior, increased BDNF expression, and reduce brain infarction in stroke rats. The objective of this study is to det...
Quantitative LC-QToF-MS Analysis of Mycochemicals in Amanita muscaria, Psilocybe spp. (Agaricomycetes), and Consumer Products
The psychedelic mushroom market has expanded rapidly due to changing regulations and increasing consumer demand. Product diversity now extends beyond traditional capsules and tablets to include gummies, powders, and confectionery items, complicating quality control efforts. To assess the quality and potential adulteration of Amanita musca-ria and Psilocybe c...
Psychedelic mushroom-containing chocolate exposures: Case series.
IntroductionThe recreational use of psilocybin or psilocin-containing products, a chemical found naturally in certain mushroom species, is on the rise across the United States. Several cases of serious clinical effects related to mushroom-containing products have recently been reported to the Food and Drug Administration (FDA). The emergence of these new pro...
PSilocybin for psYCHological and Existential Distress in PALliative Care (PSYCHED-PAL): A Multi-site, Open-label, Single Arm Phase I/II Proof-of-concept, Dose-finding, and Feasibility Clinical Trial
The goal of this multi-centre phase I/II open-label, single-arm study is to determine the safety, feasibility, therapeutic dose, and preliminary efficacy of psilocybin microdosing to treat psychological distress among patients with advanced illness. Forty patients will receive psilocybin drug product (1-3mg per day, Mon-Fri) for 4 weeks to be administered vi...
Magic of the Mushrooms: Effects of Psilocybin Decriminalization
In the past few years, psilocybin, a psychedelic compound found in "magic mushrooms" (psilocybin mushrooms), has undergone decriminalization in numerous cities across the US and has been legalized in Oregon and Colorado. Proponents of psilocybin decriminalization have emphasized its therapeutic potential in treating mental health disorders. Furthermore, psil...
Addressing a major interference in the quantification of psilocin in mouse plasma: Development of a validated liquid chromatography tandem mass spectrometry method
Psilocybin is a psychedelic compound found in some hallucinogenic "magic mushrooms". Psilocin is the active metabolite of Psilocybin, and it is the subject of several studies for the treatment of psychological disorders, such as anxiety, depression, and post-traumatic stress disorder. As such, the pharmacokinetic properties of psilocin should be evaluated to...
