Twenty participants, age 18 or older, who meet Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria for moderate to severe Alcohol Use Disorder will be randomized to open-label psilocybin (25 mg) therapy with the Visual Healing Set and Setting platform (N=10) versus psilocybin (25 mg) with a standard Set and Setting platform (N=10). The pur...
The classical psychedelic psilocybin is of interest as a treatment for alcohol use disorder (AUD). This study investigated the effects of psilocybin on voluntary ethanol consumption in adult male and female C57BL/6J mice administered saline or psilocybin intraperitoneally as a single dose of 0.1, 0.5, 1.0 or 2.0 mg/kg and provided 20% ethanol utilizing a two...
Lysergic acid Diethylamide (LSD), psilocybin, and psilocin are being intensively evaluated as potential therapeutics to treat depression, anxiety, substance use disorder, and a host of other psychiatric illnesses. Pre-clinical investigation of these compounds in rodent models forms a key component of their drug development process. In this review, we will su...
This study sought to investigate the effects of different substances on nature relatedness (NR) in the general population. An online cross-sectional survey done in Brazil investigated use of ayahuasca/DMT, mushrooms, LSD, MDMA/ecstasy, cocaine, cannabis, and alcohol. NR was assessed using the short-form version of the nature related scale (NR-6). One-way ana...
Subjective responses to psychoactive drugs have served as intriguing windows into consciousness as well as useful predictors. Subjective reactions to psychedelic molecules are particularly interesting given how they covary with subsequent improvements associated with psychedelic-assisted treatments. Although links between subjective reactions and decreases i...
The genus Psilocybe of Basidiomycota includes more than two hundred species of mushroom-forming fungi, which are widely known for the production of the secondary metabolite psilocybin, a prodrug of its in vivo dephosphorylated active metabolite psilocin [1]. Psilocybin is being currently used in numerous clinical trials including the treatment of Major Depre...
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 ...
Two sessions of psilocybin-assisted psychotherapy resulted in reduced heavy-drinking days and other alcohol-related problems relative to placebo plus psychotherapy in a randomized trial involving patients with alcohol use disorder (AUD). There were no serious adverse events associated with psilocybin administration, and no signs of psychotic disturbances. St...
Several lines of evidence suggest that classic psychedelics (5-HT2A receptor agonists or partial agonists) such as psilocybin might facilitate behavior change in individuals with substance use disorders. We conducted a multi-site, double-blind, randomized controlled trial (RCT) to assess the effects of psilocybin-assisted psychotherapy in alcohol-dependent v...
Classic psychedelics refer to substances such as lysergic acid diethylamide (LSD), psilocybin, ayahuasca, and mescaline, which induce altered states of consciousness by acting mainly on 5-HT2A receptors. Recently, the interest of psychedelics as pharmacological treatment for psychiatric disorders has increased significantly, including their use on problemati...
The beneficial effects of psilocybin-assisted psychotherapy on alcohol use disorder (AUD) are significant, based on a study published in JAMA Psychiatry last month. In general, psychedelic medications have been a focus of research, but less is known about psilocybin, and it has been 40 years since the studies with lysergic acid diethylamide (LSD) provided do...
IntroductionAlcohol use disorder is a difficult-to-treat psychiatric disorder and a major burden on public health. Existing treatment efficacy is moderate, and relapse rates are high. Preliminary findings suggest that psilocybin, a psychedelic compound, can safely and reliably occasion highly meaningful experiences that may spur a positive change in drinking...
Psilocybin is a plant alkaloid that is derived from precursors of tryptamine and is present in many different types of mushrooms. It has been utilized by indigenous peoples of Central and South America for centuries in a ceremonial setting to promote spiritual experiences. Indigenous societies have long employed psilocybin and other 5-HT2A agonist classic ps...
Previous studies have reported links between classic psychedelic use and seizures, but little remains known about prevalence and potential risk factors of classic psychedelic-related seizures. Using a sample representative of the US adult population with regard to sex, age, and ethnicity (N = 2822), this study examined the prevalence and potential risk facto...
ImportanceAlthough classic psychedelic medications have shown promise in the treatment of alcohol use disorder (AUD), the efficacy of psilocybin remains unknown.ObjectiveTo evaluate whether 2 administrations of high-dose psilocybin improve the percentage of heavy drinking days in patients with AUD undergoing psychotherapy relative to outcomes observed with a...
BackgroundClinical studies report preliminary therapeutic effects of classic psychedelic drugs in several psychiatric conditions and international drug trends show increased use of these compounds. However, the epidemiology of classic psychedelic drug use in Scandinavian countries remains sparsely investigated. To this end, we investigated the patterns of us...
Initial promise and dire need have inspired the multiple research programs of the second psychedelic renaissance. Serotonergic psychedelics (psilocybin, lysergic acid diethylamide, and ayahuasca) have decreased end-of-life anxiety in cancer patients, treatment-resistant depression, alcohol dependence, social anxiety in autistic adults, and nicotine dependenc...
Growing evidence from observational studies and clinical trials suggests that psychedelics such as lysergic acid diethylamide, 3,4-methylenedioxymethamphetamine, and psilocybin may hold treatment potential for alcohol, opioid, tobacco, and other substance use disorders (SUDs). The mechanisms by which psychedelics might exert therapeutic efficacy in these con...
Hallucinogen persisting perception disorder (HPPD) is characterized by visual disturbances that resemble psychedelic intoxication and linger after use has ceased. The most common substances precipitating HPPD, lysergic acid diethylamide (LSD) and psilocybin, are posited to do so via damage to serotonergic neurons involved in vision. Mr. N is a 37-year-old wi...
