Can Psychedelic Drugs Attenuate Age-Related Changes in Cognition and Affect ? Jacob S. Aday, Emily K. Bloesch, & Christopher C. Davoli Journal of Cognitive Enhancement, August 2019 DOI: 10.1007/s41465-019-00151-6 Abstract Older adulthood can be characterized by various cognitive and affective changes. In general, older adults show declines in creativity and executive functioning. They also score lower in openness to experience, empathy, and many suffer from a paucity of meaningful experiences. Further, depression, pessimism, and suicide can be major concerns for this population. Although currently there are few interventions that can effectively address these changes, recent findings from psychedelic science suggest myriad parallels between the effects [...]

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 [...]
Lire la suitePsilocybin-occasioned mystical-type experience in combination with meditation and other spiritual practices produces enduring positive changes in psychological functioning and in trait measures of prosocial attitudes and behaviors Roland R. Griffiths, Matthew W. Johnson, William A. Richards, Brian D. Richards3, Robert Jesse, Katherine A. MacLean, Frederick S. Barrett, Mary P. Cosimano and Maggie A. Klinedinst Journal of Psychopharmacology, 2018, 32, 1, 49-69. DOI: 10.1177/0269881117731279 Abstract 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): [...]
Lire la suiteMystical experiences occasioned by the hallucinogen psilocybin lead to increases in the personnality domain of openness Katherine A. MacLean, Matthew W. Johnson and Roland R. Griffiths Journal of Psychopharmacology, 2011, 25, (11), 1453-1461. doi: 10.1177/0269881111420188. Abstract A large body of evidence, including longitudinal analyses of personality change, suggests that core personality traits are predominantly stable after age 30. To our knowledge, no study has demonstrated changes in personality in healthy adults after an experimentally manipulated discrete event. Intriguingly, double-blind controlled studies have shown that the classic hallucinogen psilocybin occasions personally and spiritually significant mystical experiences that predict longterm changes in behaviors, attitudes and values. In [...]

Johnson, Una D. McCann, R. Jesse Journal of Psychopharmacology, 2008, 1–12. Doi : 10.1177/0269881108094300 Abstract 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 data obtained at screening and on drug session days. Participants were 36 hallucinogen-naïve adults [...]

Doi : 10.1186/s12954-019-0308-4 Abstract Background : Microdosing psychedelics is the practice of consuming very low, sub-hallucinogenic doses of a psychedelic substance, such as lysergic acid diethylamide (LSD) or psilocybin-containing mushrooms. According to media reports, microdosing has grown in popularity, yet the scientific literature contains minimal research on this practice. There has been limited reporting on adverse events associated with microdosing, and the experiences of microdosers in community samples have not been categorized. Methods : In the present study, [...]

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, [...]
