This review presents a general background of psilocybin pharmacology and discusses its uses in treating various mental health disorders such as depression, anxiety, obsessive-compulsive disorder, and addiction. A summary of preliminary clinical trials utilizing psilocybin in each disorder is presented, along with an analysis of the neurobiological mechanisms...
Depression is highly prevalent and represents the leading cause of global disability and primary contributor to overall global burden of disease. Several lines of evidence from early-phase experimental trials suggest that serotonergic psychedelics, particularly psilocybin, with therapeutic support show great promise in the treatment of depression with large ...
This manuscript reviews research suggesting that classic psychedelics (5-HT2A receptor agonists) are effective in treating addictions including tobacco use disorder. I review historical research from the 1950s to 1970s suggesting that classic psychedelics are associated with addiction recovery across pharmacologically distinct drugs of addiction. I then revi...
Introduction Classic psychedelics have been administered in sacramental contexts since ancient times. They were of prominent interest within psychiatry and neuroscience in the 1950s to 1960s, but the association between classic psychedelics and the emerging counterculture put an end to their research. Modern research with classic psychedelics has reinitiated...
Healthful behaviours such as maintaining a balanced diet, being physically active and refraining from smoking have major impacts on the risk of developing cancer, diabetes, cardiovascular diseases and other serious conditions. The burden of the so-called 'lifestyle diseases'-in personal suffering, premature mortality and public health costs-is considerable. ...

Little has been written on the financial support behind Timothy Leary's unorthodox research into mind-altering drugs like LSD and psilocybin and his subsequent psychedelic movement. Indeed several individuals and organizations helped the psychedelic cause by directly funding Leary's ventures, offering legal and logistic assistance, and organizing fund-raisin...
Depression is one of the most disabling and prevalent mental disorders, which causes excessive feelings of sadness and despair. Unfortunately, there are a substantial number of patients that do not respond well to conventional interventions and new approaches are therefore needed. Recent studies have revealed that psilocybin can effectively reduce symptoms o...
Addictive disorders are very common and have devastating individual and social consequences. Currently available treatment is moderately effective at best. After many years of neglect, there is renewed interest in potential clinical uses for classic hallucinogens in the treatment of addictions and other behavioral health conditions. In this paper we provide ...
Despite suggestive early findings on the therapeutic use of hallucinogens in the treatment of substance use disorders, rigorous follow-up has not been conducted. To determine the safety and feasibility of psilocybin as an adjunct to tobacco smoking cessation treatment we conducted an open-label pilot study administering moderate (20 mg/70 kg) and high (30 mg...
The involvement of the serotonin system in the pathophysiology of schizophrenia has been elucidated by experiments with hallucinogens. Application of a hallucinogen to humans leads to changes in perception, cognition, emotions, and induction of psychotic-like symptoms that resemble symptoms of schizophrenia. In rodent studies, their acute administration affe...
Hallucinogen-based interventions may benefit substance use populations, but contemporary data informing the impact of hallucinogens on addictive behavior are scarce. Given that many individuals in the criminal justice system engage in problematic patterns of substance use, hallucinogen treatments also may benefit criminal justice populations. However, the re...
This paper presents original research on prevalence, user characteristics and effect profile of N,N-dimethyltryptamine (DMT), a potent hallucinogenic which acts primarily through the serotonergic system. Data were obtained from the Global Drug Survey (an anonymous online survey of people, many of whom have used drugs) conducted between November and December ...
BackgroundThe classical serotonergic psychedelics LSD, psilocybin, mescaline are not known to cause brain damage and are regarded as non-addictive. Clinical studies do not suggest that psychedelics cause long-term mental health problems. Psychedelics have been used in the Americas for thousands of years. Over 30 million people currently living in the US have...
Although psilocybin has been trained in the rat as a discriminative stimulus, little is known of the pharmacological receptors essential for stimulus control. In the present investigation rats were trained with psilocybin and tests were then conducted employing a series of other hallucinogens and presumed antagonists. An intermediate degree of antagonism of ...
Abuse of natural products was frequently noticed among young patients with multiple substance abuse. 180 patients of a rehabilitation clinic for young addicts filled out a questionnaire regarding their regularly consumed drugs. Ayahuasca and cactus, the natural drugs of the 70's are rarely found. The patients frequently consumed psilocybin, amanita and datur...
