The goal of this clinical trial is to learn if psilocybin, given with psychological support, is safe and helps treat anorexia nervosa in young adults. Anorexia nervosa is a serious eating disorder that currently has no approved medicine. Psilocybin is a psychedelic substance that may help the brain form new connections, which could make it easier for people ...
Introduction: Major depressive disorder (MDD) affects over 21 million adults in the U.S (NIMH, 2023) and remains a significant public health challenge. Despite the effectiveness of traditional medications, 30% of patients remains resistant. Little is known about the beliefs individuals hold regarding novel treatments, such as psilocybin and the motivations b...
Serotonergic psychedelics and 3,4-methylendioxtmethamphetamine (MDMA) are promising treatments for mental disorders with a continuously evolving evidence base. We searched Pubmed/Scopus/clinical trial registries up to 08july2025 for double-blind randomized controlled trials (RCTs) testing MDMA or serotonergic psychedelics in patients with mental disorders. P...
Background and Aims The ongoing opioid epidemic remains a major public health crisis in the United States, with over 100,000 opioid-related deaths annually. Mental health disorders are strongly associated with opioid use disorder (OUD), compounding risks of misuse and overdose. Emerging evidence indicates that psychedelics may be associated with reduced risk...
IntroductionBipolar disorder (BD) is a severe and persistent mental disorder characterized by recurrent mood episodes, with BD depression accounting for most of the illness burden. Although the mainstay treatment of BD consists of pharmacotherapy with mood stabilizers and atypical antipsychotics, a large proportion of patients with BD depression do not respo...
Abstract Background Self-transcendent and mystical experiences may be key mechanisms underlying psychedelics’ therapeutic effects, yet how these experiences differ across substances remains unclear. This study compared mystical and self-transcendent experiences across psilocybin, 3,4-Methylenedioxymethamphetamine (MDMA), and cannabis in a diverse, community-...
Psilocybin has profound therapeutic potential for various mental health disorders, but its mechanisms of action are unknown. Functional MRI studies have reported the effects of psilocybin on brain activity and connectivity; however, these measurements rely on neurovascular coupling to infer neural activity changes and assume that blood flow responses to neur...
The influence of ovarian hormone fluctuations on neurochemistry, cognition, and psychological responses remains insufficiently examined in current psychedelic research and clinical protocols. Traditional practices and case studies underscore the importance of accounting for these factors in investigations of psychedelic effects. This opinion paper explores t...
Psilocin is a well-studied controlled substance with potential psychotherapeutic applications. However, research gaps remain regarding its metabolism. Our objective was to elucidate a comprehensive Phase I metabolic profile of psilocin to support its forensic management and clinical development. We utilized human enzymes from various sources to characterize ...
BACKGROUND: Short-lasting unilateral neuralgiform headache attacks (SUNHA) are trigeminal autonomic cephalalgias that feature intense and recurrent paroxysms of pain and autonomic symptoms. Many patients are left with debilitating symptoms despite best-available treatment. Psychedelics, such as the serotonin 2A partial agonist psilocybin, have shown promise ...
This study aims to estimate the lower, middle, and upper bounds of potential demand for psilocybin-assisted therapy (PSIL-AT) for major depressive disorder (MDD) and treatment-resistant depression (TRD) in the United States. We calculated potential PSIL-AT demand for MDD and TRD by estimating the number of U.S. patients with MDD, identifying those in treatme...
Interest in the therapeutic potential of psilocybin across a broad range of neuropsychiatric disorders is rapidly expanding. Despite promising clinical data and tremendous public enthusiasm, complimentary basic and translational studies - which are critical for advancing our understanding of psilocybin's biological effects and promoting innovation - have bee...
Several lines of evidence suggest that classic hallucinogens such as psilocybin can facilitate behavior change in addictions such as alcohol dependence. The proposed investigation is a multi-site, double-blind active-controlled trial (n = 180, 90 per group) contrasting the acute and persisting effects of psilocybin to those of diphenhydramine in the context ...
BackgroundWe draw on both interdisciplinary enhancement substance use research and critical drug studies scholarship to reconceptualise enhancement substance use. Our critical discourse approach illuminates how a variety of substances are positioned as tools for self-improvement. In reconceptualising enhancement substance use, we ask what different substance...
Machine Learning is used to predict the efficacy of psilocybin in treating mental health and addiction by using a random forest algorithm. Psilocybin is a chemical compound found in fungi. Following ingestion, it is converted to psilocin which acts as a serotonin agonist, producing altered states of consciousness and hallucinations. Research suggests the use...
IntroductionProblems associated with the increasing abuse of plant-derived psychoactive substances have recently attracted attention. This study involved bioanalytical and clinical examinations of intoxication cases suspected to be linked to such plant materials.MethodsUrine samples were collected at emergency wards in Sweden from patients who either admitte...
