Interest in psychedelics has expanded beyond clinical treatment contexts, yet little empirical work has examined how users describe psychedelic use in relation to sport and physical activity. This study conducted a qualitative content analysis of Reddit discussions involving psychedelics and physical performance. A Reddit search for “sports psychedelics” ret...
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, no...
Anxiety disorders are chronic health conditions affecting the quality of life of millions of people. Psilocin, the active moiety of psilocybin, provides an anxiolytic effect; however, when orally administered as psilocybin, it only offers a moderate level of bioavailability and less predictable pharmacokinetics, potentially making effects after absorption va...
Psilocybin is a classic psychedelic drug known to alter subjective experience and elicit long-term psychological changes, enhancing cognitive flexibility and reducing rigid self-related beliefs. Combined with compassion motivational primes that involve generating mental representations of compassion, it may increase the potential for activating the care-affi...
BACKGROUND: The consumption of dried fruiting bodies of Psilocybe cubensis can be traced over centuries, guided by Mesoamerican curanderas, Western medical practitioners, and fungal enthusiasts, all seeking mental wellbeing. There is a notable resurgence in interest both in the fungal biomass and psilocybin, the psychoactive tryptamine, despite the global re...
Background and objectivePsilocybin is currently being extensively studied as a potential therapeutic agent for multiple psychiatric disorders. Here, a systematic literature review of all published pharmacokinetic data on the pharmacologically active metabolite of psilocybin, psilocin, is presented.MethodsThe review includes clinical studies that reported pha...
BACKGROUND: To investigate the association between pre-trial expectancy, suggestibility, and response to treatment in a trial of escitalopram and investigational drug, COMP360, psilocybin, in the treatment of major depressive disorder (ClinicalTrials.gov registration: NCT03429075). METHODS: = 55) from our recent double-blind, parallel-group, randomized head-...
Abstract Background Psilocybin Therapy (PT) is being increasingly studied as a psychiatric intervention. Personality relates to mental health and can be used to probe the nature of PT's therapeutic action. Methods In a phase 2, double-blind, randomized, active comparator controlled trial involving patients with moderate-to-severe major depressive disorder, w...
The salification and prodrug approaches modulate the physicochemical properties and absorption, distribution, metabolism, excretion, and toxicity parameters of drugs and lead candidates. The "phosphate" is one of the key counterions/promoiety used in the salt formation and prodrug synthesis. Salification with phosphoric acid enhances the aqueous solubility a...
Spontaneous Spiritual Awakenings (SSAs) are subjective experiences characterised by a sudden sense of direct contact, union, or complete nondual merging (experience of oneness) with a perceived ultimate reality, the universe, "God," or the divine. These profound transformative experiences have scarcely been researched, despite extensive anecdotal evidence su...

Psilocybin is being developed for treating major depressive disorder. Psilocybin is readily dephosphorylated to psilocin upon absorption. The potential for psilocin proarrhythmic effect was assessed using a concentration-QTc interval (C-QTc) analysis from an open-label single ascending dose study of psilocybin. Psilocybin doses ranged from 0.3 to 0.6 mg/kg. ...
N-Benzylphenethylamines, commonly known as NBOMes, are synthetic psychedelic compounds derived from the phenethylamine class of psychedelics (2C-X compounds), which originally have been derived from the naturally occurring alkaloid mescaline. Analogously to their parent compounds and other classical psychedelics, such as psilocybin and lysergic acid diethyla...
BackgroundMescaline (3,4,5-trimethoxyphenethylamine), mainly found in the Peyote cactus (Lophophora williamsii), is one of the oldest known hallucinogenic agents that influence human and animal behavior, but its psychoactive mechanisms remain poorly understood.ObjectivesThis article aims to fully review pharmacokinetics and pharmacodynamics of mescaline, foc...
RationaleAlthough psilocybin and dextromethorphan (DXM) are hallucinogens, they have different receptor mechanisms of action and have not been directly compared.ObjectiveThis study compared subjective, behavioral, and physiological effects of psilocybin and dextromethorphan under conditions that minimized expectancy effects.MethodsSingle, acute oral doses of...
Responses to hallucinogenic drugs, such as psilocybin, are believed to be critically dependent on the user's personality, current mood state, drug pre-experiences, expectancies, and social and environmental variables. However, little is known about the order of importance of these variables and their effect sizes in comparison to drug dose. Hence, this study...
Pharmacologic and toxic effects of xenobiotics, such as drugs of abuse, depend on the genotype and phenotype of an individual, and conversely on the isoenzymes involved in their metabolism and transport. The current knowledge of such isoenzymes of frequently abused therapeutics such as opioids (oxycodone, hydrocodone, methadone, fentanyl, buprenorphine, tram...
This paper reports an investigation into the temporal stability of aqueous solutions of psilocin and psilocybin reference drug standards over a period of fourteen days. This study was performed using high performance liquid chromatography utilising a (95:5% v/v) methanol: 10 mM ammonium formate, pH 3.5 mobile phase and absorption detection at 269 nm. It was ...
This paper describes a procedure for the determination of psilocin and psilocybin in mushroom extracts using high-performance liquid chromatography with postcolumn chemiluminescence detection. A number of extraction methods for psilocin and psilocybin in hallucinogenic mushrooms were investigated, with a simple methanolic extraction being found to be most ef...
