Psychedelics have been already used by human societies for more than 3000 years, mostly in religious and healing context. The renewed interest in the potential application of psychedelic compounds as novel therapeutics has led to promising preliminary evidence of clinical benefit in some psychiatric disorders. Despite these promising results, the potential f...

The current protocol is a pilot study of the effects and possible utility of psilocybin-facilitated experiences for professional religious leaders. We hypothesize that religious professionals, given their interests, training, and life experience, will be able to make nuanced discriminations of their psilocybin experiences, thus contributing to the scientific...
Background: Practitioners in a variety of spiritual/religious traditions have described “mystical experiences”, defined by a common set of qualities. The “Mystical Experience Questionnaire” (MEQ30) provides a validated and quantitative measure of mystical experience, and has been used successfully to demonstrate that the hallucinogenic substance psilocybin t...

cancer patient: cancer patientWith the technological advances that have been made in diagnostics for cancer, more disease is being detected at an earlier stage. Although this generally improves the patient's chances for survival, a diagnosis of cancer can often provoke significant psychological distress in patients. A significant number of cancer patients wi...
Despite their acutely inebriating and sometimes unpleasant effects, some people report positive changes in life satisfaction, well-being, or mental health after taking psychedelic drugs. One explanation may be the ability of psychedelics to trigger mystical-type experiences. We examined the validity, reliability, and factor structure of a novel Finnish trans...
This paper formulates the action of psychedelics by integrating the free-energy principle and entropic brain hypothesis. We call this formulation relaxed beliefs under psychedelics (REBUS) and the anarchic brain, founded on the principle that-via their entropic effect on spontaneous cortical activity-psychedelics work to relax the precision of high-level pri...
Naturally occurring and psychedelic drug-occasioned experiences interpreted as personal encounters with God are well described but have not been systematically compared. In this study, five groups of individuals participated in an online survey with detailed questions characterizing the subjective phenomena, interpretation, and persisting changes attributed ...
This research is being done to study the psychological effects of psilocybin in cancer patients. Psilocybin is a naturally occurring substance found in some mushrooms that some cultures have used for centuries in religious practices. This research is being done to study the psychological effects of psilocybin in cancer patients. Psilocybin is a naturally occ...
This chapter begins with a brief review of descriptions and definitions of mystical-type experiences and the historical connection between classic hallucinogens and mystical experiences. The chapter then explores the empirical literature on experiences with classic hallucinogens in which claims about mystical or religious experiences have been made. A psycho...
Psilocybin can occasion mystical-type experiences with participant-attributed increases in well-being. However, little research has examined enduring changes in traits. This study administered psilocybin to participants who undertook a program of meditation/spiritual practices. Healthy participants were randomized to three groups (25 each): (1) very low-dose...
Recent randomized controlled trials of psilocybin-assisted psychotherapy for patients with cancer suggest that this treatment results in large-magnitude reductions in anxiety and depression as well as improvements in attitudes toward disease progression and death, quality of life, and spirituality. To better understand these findings, we sought to identify p...
RationaleDuring the last years, considerable progress has been made toward understanding the neuronal basis of consciousness by using sophisticated behavioral tasks, brain-imaging techniques, and various psychoactive drugs. Nevertheless, the neuronal mechanisms underlying some of the most intriguing states of consciousness, including spiritual experiences, r...
A large body of historical evidence describes the use of hallucinogenic compounds, such as psilocybin mushrooms, for religious purposes. But few scientific studies have attempted to measure or characterize hallucinogen-occasioned spiritual experiences. The present study examined the factor structure of the Mystical Experience Questionnaire (MEQ), a self-repo...
Psilocybin has been used for centuries for religious purposes; however, little is known scientifically about its long-term effects. We previously reported the effects of a double-blind study evaluating the psychological effects of a high psilocybin dose. This report presents the 14-month follow-up and examines the relationship of the follow-up results to dat...
Accompanying the resumption of human research with the entheogen (psychedelic drug), psilocybin, the range of states of consciousness reported during its action, including both nonmystical and mystical forms of experience, is surveyed and defined. The science and art of facilitating mystical experiences is discussed on the basis of research experience. The p...
