‘Why is psychedelic culture dominated by privileged white men?’ asks historian Mike Jay, referring to a recent study of psychedelic users who are more than likely to be college-educated white males.1 This appears logical, given the figureheads (such as Timothy Leary) who attained cult-like status half a century ago. Many today continue to view psychedelics a...
Psilocybin is the psychoactive compound of mushrooms in the psilocybe species. Psilocybin directly affects a number of serotonin receptors, with highest affinity for the serotonin 2A receptor (5HT-2Ar). Generally, the effects of psilocybin, and its active metabolite psilocin, are well established and include a range of cognitive, emotional, and perceptual pe...
Psychiatry is in a crisis. Mental health disorders are on the rise worldwide and there are currently not enough efficient treatment methods that would meet the patients’ needs. Hence, the societal and economic costs of mental health problems are enormous, as well as the suffering of individuals afflicted by mental health problems. Lysergic acid diethylamide ...
An exploration of personality predictor variables (absorption and temporal lobe lability) and acute experience measures (5D-ASC) in the comparison of several non-drug induced altered states (darkroom anechoic chamber, floatation tank and holotropic breathwork) with psychedelic altered states (e.g., DMT, psilocybin, cannabis).
psilocybin; depression; terminal cancer; CME; CNE: psilocybin; depression; terminal cancer; CME; CNEPsilocybin is a naturally occurring alkaloid found in more than 200 species of mushrooms. This compound, which was first isolated by the Swiss chemist Albert Hofman in 1959, is the active constituent of psychedelic mushrooms which are thought to have been util...
Classic psychedelic substances, such as lysergic acid diethylamide and the active compound in magic mushrooms, psilocybin, are being studied again in a renaissance of psychedelic research. Psychedelic substances have profound effects on perception, emotion, and cognition, as well as the capacity to induce mystical-type experiences and ego-dissolution. Recent...
In recent years, the scientific study of meditation and psychedelic drugs has seen remarkable developments. The increased focus on meditation in cognitive neuroscience has led to a cross-cultural classification of standard meditation styles validated by functional and structural neuroanatomical data. Meanwhile, the renaissance of psychedelic research has she...
Ever since the modern rediscovery of psychedelic substances by Western society, several authors have independently proposed that their effects bear a high resemblance to the dreams and dreamlike experiences occurring naturally during the sleep-wake cycle. Recent studies in humans have provided neurophysiological evidence supporting this hypothesis. However, ...
Introduction: It is a basic principle of the "psychedelic" treatment model that the quality of the acute experience mediates long-term improvements in mental health. In the present paper we sought to test this using data from a clinical trial assessing psilocybin for treatment-resistant depression (TRD). In line with previous reports, we hypothesized that th...
Serotonergic hallucinogens, such as lysergic acid diethylamide (LSD), psilocybin, and N,N-dimethyltryptamine (DMT), are famous for their capacity to temporally and profoundly alter an individual's visual experiences. These visual alterations show consistent attributes despite large inter- and intra-individual variances. Many reports document a common percept...
Classic serotonergic hallucinogens or psychedelics produce an altered states of consciousness (ASC) that is characterized by profound alterations in sensory perception, mood, thought including the perception of reality, and the sense of self. Over the past years, there has been considerable progress in the search for invariant and common features of psychede...
The classic serotonergic hallucinogens, or psychedelics, have the ability to profoundly alter perception and behavior. These can include visual distortions, hallucinations, detachment from reality, and mystical experiences. Some psychedelics, like LSD, are able to produce these effects with remarkably low doses of drug. Others, like psilocybin, have recently...
Rationale: Stimulation of serotonin 2A (5-HT2A) receptors by lysergic acid diethylamide (LSD) and related compounds such as psilocybin has previously been shown to increase primary process thinking - an ontologically and evolutionary early, implicit, associative, and automatic mode of thinking which is typically occurring during altered states of consciousne...
Acute adverse psychological reactions to classic hallucinogens ("bad trips" or "challenging experiences"), while usually benign with proper screening, preparation, and support in controlled settings, remain a safety concern in uncontrolled settings (such as illicit use contexts). Anecdotal and case reports suggest potential adverse acute symptoms including a...
RationaleLysergic acid diethylamide (LSD) is used recreationally and in clinical research. Acute mystical-type experiences that are acutely induced by hallucinogens are thought to contribute to their potential therapeutic effects. However, no data have been reported on LSD-induced mystical experiences and their relationship to alterations of consciousness. A...
Mushrooms are probably the best known fungi and usually found springing up on dead wood after cool, wet weather; the mushroom is a common sight. Psilocybin mushrooms, also known as psychedelic mushrooms, are mushrooms that contain the psychedelic compounds psilocybin and psilocin. It is used mainly as an antigen and recreational drug whose effects can includ...
Earlier this year I joined some friends at a performance by the New York Philharmonic of Verdi’s Requiem Mass. Not one of us was Catholic or professed any creed threatening an afterlife of eternal suffering for the wicked. No perpetual willies over Judgment Day. Nevertheless, when the massed voices of chorus and orchestra unleashed their frenzy in the climac...
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...
