Psilocybe cubensis are a group of mushrooms containing psilocybin with a history of consumption dating back to ancient civilization. Researchers believe the ritual use of psilocybin dates back 3,000 years amongst the indigenous people of Mexico and Central America.1 Psilocybin is responsible for the effects associated with the consumption of “Magic Mushrooms...
Background: The primary psychoactive drug in magic mushrooms, psilocybin induces profound alterations in consciousness through its action at the 5-HT2A receptor. This comprehensive review consolidates current research findings to elucidate the pharmacology, safety profile, and clinical applications of psilocybin.Areas of Uncertainty: Despite initial concerns...

IntroductionDepression is a common disabling psychiatric disorder, which - in extreme cases - may lead to suicide if untreated or inadequately treated. Despite the availability of various treatments for depression, including pharmacotherapy, there is still a need to search for new agents with higher effectiveness and faster onset of action, especially for pa...
Psilocybin is a classical psychedelic which has been utilised for healing purposes for millenia. However, with its classification as a Schedule I substance, research into this compound is scarce with few FDA-approved clinical studies. Despite this, profound findings into its antidepressant effects (largely through its action on 5-HT1a receptors) in mental il...
Introduction Psilocybin is considered a classical psychedelic and is increasingly attracting scientific and media attention as an alternative approach to the treatment of various mental disorders. Apart from its efficacy, an important question is the tolerability and safety of psilocybin in general and in a controlled environment. Accurate knowledge of drug ...
Successful therapy of mental disorders is very important in view of the high level of suffering of those affected. Since established pharmaceutical and psychotherapeutic approaches do not lead to the desired improvement in all cases, complementary or alternative treatment methods are intensively researched. Psilocybin-assisted psychotherapy seems particularl...
Purpose of reviewThis review article summarizes clinically and socially relevant developments over the past five years in the therapeutic use of the classical tryptamine psychedelic substance psilocybin, with respect to the common challenges faced by palliative care patients and their care teams. Psilocybin is available in whole fungal and isolated forms but...
Mescaline (the active substance in Peyote and San Pedro cacti) is a classic and long known serotonergic psychedelic substance (hallucinogen) that is widely used for recreational, spiritual, and/or ethno medical purposes. Despite its long history, modern data on the acute effects of mescaline on human is lacking. Mescaline produces prototypical psychedelic ef...
BackgroundPsychedelic-assisted therapy [e.g., with lysergic acid diethylamide (LSD)] has shown promising results as treatment for substance use disorders (SUDs). Previous systematic reviews assessing the efficacy of psilocybin in SUDs only included clinical trials conducted in the last 25 years, but they may have missed clinical trials assessing the efficacy...
In 2020, Oregon voters passed the Oregon Psilocybin Services Act (PSA). The PSA allows for the adult use of psilocybin at designated service centers and does not require a medicinal purpose for consumption. While the use of psilocybin becomes legal in Oregon in 2023 under the PSA, psilocybin remains a Schedule I substance under the federal Controlled Substan...
Psilocybin is an emerging potential therapy for the treatment of psychiatric illnesses. Microdosing has been shown to result in an overall improvement in patients with anxiety, depression, obsessive-compulsive disorder, post-traumatic stress disorder, and substance abuse. This meta-analysis explores and compiles prior research to make further inferences rega...
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...
New medicines containing classic hallucinogenic and entactogenic psychedelic substance are under development for various psychiatric and neurological disorders. Many of these, including psilocybin, lysergic acid diethylamide (LSD), and 3,4-methylenedioxymethamphetamine (MDMA) are Schedule I controlled substances of the United States Controlled Substances Act...
Existing pharmacological treatments for psychiatric disorders have demonstrated limited efficacy, delayed onset of action, and significant burden of side effects. Recent findings from human studies with psychedelics have shown promise, demonstrating rapid and sustained clinical benefits of these compounds for a variety of psychiatric disorders. Classical psy...
The Food and Drug Administration (FDA) granted breakthrough therapy status to 3,4-methylenedioxymethamphetamine-assisted therapy (MDMA-AT) in 2017 due to preliminary evidence supporting its efficacy and safety in treating post-traumatic stress disorder (PTSD). A series of six phase-II clinical trials studying MDMA-AT for treatment-resistant PTSD found that...
International drug policy is rapidly evolving in tandem with promising evidence for psychedelic-assisted psychotherapy (PAP) in treating a range of mental health conditions. Canada is among the countries increasingly expanding access to psychedelic substances for therapeutic purposes. The 8-year ban on medical exemptions through the Canadian Special Access P...
Growing interest has been seen in using lysergic acid diethylamide (LSD) and psilocybin in psychiatric research and therapy. However, no modern studies have evaluated differences in subjective and autonomic effects of LSD and psilocybin or their similarities and dose equivalence. We used a double-blind, randomized, placebo-controlled, crossover design in 28 ...
BackgroundLSD and psilocybin are increasingly used in phase I trials and evaluated as therapeutic agents for mental disorders. The phenomenon of reoccurring drug-like experiences after the acute substance effects have worn off was described for both substances and especially attributed to LSD. According to the DSM-V, the persisting and distressing manifestat...
BackgroundThe therapeutic options for neurobehavioral disorders are still limited, and in many cases, they lack a satisfactory balance between efficacy and side effects.ObjectivesThis work aims to review current evidence regarding the potential contribution of psychedelics and hallucinogens to the discovery of new drugs for treating different psychiatric dis...
