The epidemiology of 5-Methoxy-N,N-Dimethyltryptamine (5-MeO-DMT) use: Benefits, consequences, patterns of use, subjective effects, and reasons for consumption Alan K. Davis, Joseph P. Barsuglia, Rafael Lancelotta, Robert M. Grant, and Elise Renn Journal of Psychopharmacology, 2018, 32, (7), 779–792. doi : 10.1177/0269881118769063   Abstract Background/Aim : 5-Methoxy-N,N-Dimethyltryptamine (5-MeO-DMT) is a psychoactive compound found in several plants and in high concentrations in Bufo alvarius toad venom. Synthetic, Toad, and Plant-sourced 5-MeO-DMT are used for spiritual and recreational purposes and may have psychotherapeutic effects. However, the use of 5-MeO-DMT is not well understood. Therefore, we examined patterns of use, motivations for consumption, subjective effects, and potential benefits and consequences [...]

Intensity of Mystical Experiences Occasioned by 5-MeO-DMT and Comparison With a Prior Psilocybin Study, Joseph Barsuglia et al., 2018

Intensity of Mystical Experiences Occasioned by 5-MeO-DMT and Comparison With a Prior Psilocybin Study Joseph Barsuglia, Alan K. Davis, Robert Palmer, Rafael Lancelotta, Austin-Marley Windham-Herman, Kristel Peterson, Martin Polanco, Robert Grant and Roland R. Griffiths Frontiers in Psychology, 2018, Vol 9, Article doi : 10.3389/fpsyg.2018.02459   5-MeO-DMT is a psychoactive substance found in high concentrations in the bufotoxin of the Colorado River Toad (Bufo alvarius). Emerging evidence suggests that vaporized 5-MeO-DMT may occasion mystical experiences of comparable intensity to those occasioned by more widely studied psychedelics such as psilocybin, but no empirical study has tested this hypothesis. Data was obtained from 20 individuals (Mage = [...]

The Varieties of the Psychedelic Experience: A Preliminary Study of the Association Between the Reported Subjective Effects and the Binding Affinity Profiles of Substituted Phenethylamines and Tryptamines Federico Zamberlan, Camila Sanz, Rocío Martínez Vivot, Carla Pallavicini, Fire Erowid, Earth Erowid and Enzo Tagliazucchi Frontiers in Integrative Neuroscience, 2018, 12, 54. doi : 10.3389/fnint.2018.00054   Classic psychedelics are substances of paramount cultural and neuroscientific importance. A distinctive feature of psychedelic drugs is the wide range of potential subjective effects they can elicit, known to be deeply influenced by the internal state of the user (“set”) and the surroundings (“setting”). The observation of crosstolerance and a series [...]

Its active agents are b-carboline and tryptamine derivatives. As a sacrament, ayahuasca is still a central element of many healing ceremonies in the Amazon Basin and its ritual consumption has become common among the mestizo populations of South America. Ayahuasca use amongst the indigenous people of the Amazon is a form of traditional medicine and cultural psychiatry. During the last two decades, the [...]

Psilocybin can occasion mystical-type experiences having substantial and sustained personal meaning and spiritual significance, Roland R. Griffiths et al., 2006

Psilocybin can occasion mystical-type experiences having substantial and sustained personal meaning and spiritual significance Roland R. Griffiths, William A. Richards, Una McCann, Robert Jesse Psychopharmacology, 2006 DOI 10.1007/s00213-006-0457-5   Abstract Rationale : Although psilocybin has been used for centuries for religious purposes, little is known scientifically about its acute and persisting effects. Objectives : This double-blind study evaluated the acute and longer-term psychological effects of a high dose of psilocybin relative to a comparison compound administered under comfortable, supportive conditions. Materials and methods : The participants were hallucinogennaïve adults reporting regular participation in religious or spiritual activities. Two or three sessions were conducted at 2-month intervals. Thirty volunteers [...]

The administration of psilocybin to healthy, hallucinogen-experienced volunteers in a mock-functional magnetic resonnance imaging environment : a preliminary investigation of tolerability, Robin L. Carhart-Harris et al., 2010

The administration of psilocybin to healthy, hallucinogen-experienced volunteers in a mock-functional magnetic resonnance imaging environment : a preliminary investigation of tolerability Robin L. Carhart-Harris et al., Journal of Psychopharmacology, 2010, 1-6 DOI: 10.1177/0269881110367445   Abstract This study sought to assess the tolerability of intravenously administered psilocybin in healthy, hallucinogen-experienced volunteers in a mock-magnetic resonance imaging environment as a preliminary stage to a controlled investigation using functional magnetic resonance imaging to explore the effects of psilocybin on cerebral blood flow and activity. The present pilot study demonstrated that up to 2 mg of psilocybin delivered as a slow intravenous injection produces short-lived but typical drug effects that [...]

A Comprehensive Literature Review Jonathan Freedlander Journal of Drug Education and Awareness, 2003 https://www.researchgate.net/publication/287670047_Ibogaine_A_novel_anti-addictive_compound   Introduction and History Ibogaine is a naturally occurring indole alkaloid, found in a variety of African shrubs of the Tabernathe genus (Obach, Pablo, and Mash, 1998). The root of the Tabernanthe iboga plant (also known as eboga) is the most frequently cited source of ibogaine, and this plant contains 11 other known psychoactive constituents (Popik, and Skolnick, 1999). Chemically, ibogaine is classified as a tryptamine, being a rigid analogue of melatonin, and is structurally similar to harmaline, another natural alkaloid and psychedelic (Xu et al, [...]
