Background: Psilocybin-assisted therapy (PAT) has shown promise for alcohol use disorder (AUD) in randomized controlled trials (RCTs). However, the effects of open-label administration following blinded treatment are unclear. Here, we present safety and efficacy data from an open-label extension of a Phase II RCT (NCT02061293) examining PAT for AUD. Methods: Adults with AUD (N = 59) received a...

Background/Objectives: Psilocybin has re-emerged as a promising intervention for neuropsychiatric disorders including major depressive disorder, treatment-resistant depression, anxiety associated with life-threatening illness, obsessive compulsive disorder, and substance use disorders. However, conventional randomized controlled trials (RCTs)-the current gold standard in evidence-based...
Uncovering the neural basis of psychedelics’ potent effects on brain activity and conscious experience has great potential for understanding their therapeutic effects. Numerous studies using functional magnetic resonance imaging (fMRI) uncovered a strong effect of psychedelics on global properties of fMRI signal, but how they map to underlying neural phenomena remains to be further explored. In...
Psilocybin, chemically known as (4-phosphoryloxy-N, N-dimethyltryptamine, 4-PODMT), is derived from the psychoactive mushroom genus, Psilocybe. Of the four active metabolites, psilocin readily enters systemic circulation. The psychoactive effects of psilocin are thought to arise through partial agonist effects at the 5-HT2A receptor. Psychedelic drugs, including psilocybin, are having a...

BACKGROUND: Substance use disorders remain a global public health problem. In recent decades, the drug market has undergone substantial changes, with traditional drugs increasingly replaced by new psychoactive substances characterized by high toxicity and strong addictive potential. Their distribution via the Internet and social media impedes control and increases risks to public health. AIM:...
While the limitations of existing treatment options have spurred investigations into the applicability of psychedelic therapies for chronic and treatment-resistant psychological disorders, there remain significant unresolved issues pertaining to how these treatments should be regulated and the implementation of an ethical framework for their widespread delivery in practice. Research...
Nach einer Pause gibt es heute wieder Evidenz-Quickies, und zwar gleich mehrere, dafür aber kürzer und weniger ausführlich als zuletzt. Und dieses Format ist jetzt zweigeteilt: (a) Für alle, denen die Nachricht genügt, gibt es oben die Quickies in Kürze. (b) Alle, die weiterlesen wollen, finden die detaillierten Fassungen unten. Viel Freude und hoffentlich interessante Lektüre! 🍄 Psilocybin bei...
Depression and psychological distress are highly prevalent among patients with cancer and are associated with impaired quality of life, reduced treatment adherence, and poorer clinical outcomes. Standard pharmacological and psychosocial interventions often demonstrate limited efficacy or delayed onset of action in oncological and palliative settings. Psilocybin-assisted therapy has recently...
ABSTRACT Accidental ingestion of psilocybin‐containing mushrooms can cause poisoning and hallucinations, making their rapid detection a public health priority. Conventional methods such as HPLC, GC–MS, LC–MS, TLC, CE, and ELISA provide sensitivity but are often destructive, time‐consuming, or impractical for real‐time applications. This study introduces a Raman spectroscopy–based approach for...
Psilocybin-assisted therapies are innovative therapeutic approaches, particularly in the treatment of depression. However, there are sparse studies providing functional magnetic resonance imaging (fMRI) evidence elucidating the underlying biological mechanisms that support clinical outcomes. This review aims to comprehensively gather all the evidence reported in psilocybin studies using fMRI...
IntroductionThe use of psychedelics has increased in Canada in recent years. Although non-medical psilocybin use is prohibited under the Controlled Drugs and Substances Act, we previously documented the emergence of grey-market brick-and-mortar psilocybin retailers. This study examined changes in the number, composition, and geographic distribution of Canadian psilocybin retail stores between...
Can a guided psychedelic experience with psilocybin successfully treat refractory depression? In other words, setting aside any simple direct biological drug effect, can psychedelic-assisted psychotherapy1 alleviate suffering via what William James would call a mystical experience?2
Importance: Psilocybin shows promise in treating depression, although limitations of previous research warrant further research. Objective: To investigate the efficacy and safety of oral psilocybin, 25 mg, with adjunct psychotherapy in treatment-resistant depression (TRD). Design, Setting, and Participants: This was a 2-center, triple-blinded (investigator, participant, rater), phase 2b, active...
Introduction This computational modeling study introduces a novel Explainable Artificial Intelligence (XAI) framework for optimizing single-dose psilocybin treatment protocols through personalized intervention modeling using publicly available mental health datasets. All results presented are derived from novel simulated data and predictive modeling only, not from real-time clinical...
The prevailing Western perspective pathologizes failure, fostering dependence on egoic success metrics. In contrast, transpersonal psychology views failure as a necessary descent and a catalyst for postegoic identity formation. This review argues that curiosity and awe are the essential mediators that transform the ego-shattering experience of failure into a catalyst for transpersonal...
Aims The recent regulatory approval of esketamine in adults heralded the renaissance of research into psychedelic compounds. However, the relevance of this resurgence for children and adolescents remains unclear. This review examines the rationale for investigating psychedelics in pediatric psychopharmacology. Methods We reviewed recent literature, regulatory documents, and clinical trial...
BACKGROUND: Current treatments for obsessive-compulsive disorder (OCD), including serotonin reuptake inhibitors and cognitive-behavioral therapy, are often insufficient. Psilocybin, a 5HT2a agonist psychedelic, has shown promise for treating OCD, but rigorous evidence is still needed. AIMS: This randomized clinical trial evaluated safety, tolerability, and benefit of multiple psilocybin doses...
Background: Cancer patients often experience significant emotional burdens due to the diagnosis, treatment process, and uncertainty regarding their prognosis. Psilocybin, a psychedelic compound found in certain mushroom species, has gained increasing attention in mental health research for its potential therapeutic effects in treating depression and anxiety. Methods: This systematic review...

Clinical trials suggest that a single dose of psilocybin may be an effective treatment for substance use disorders. Choice impulsivity is a value-based decision-making bias that predicts drug-intake escalation and is commonly associated with substance use disorders. The dorsomedial prefrontal cortex regulates choice impulsivity and is enriched with 5-HT2A receptors that mediate effects of...
