Powerful substances in tiny amounts: Exploring the practice of microdosing psychedelic drugs Petter Grahl Johnstad, Pré-Print, 2017. This article presents an explorative study of microdosing practices with psychedelic drugs. A microdose is defined as a sub-perceptual dose, commonly about one tenth of an ordinary recreational dose, which gives no alteration of consciousness or feeling of intoxication. Respondents (n = 17) were recruited at several Internet fora for individual interviews mediated via private messaging. Every participant was male, and the median respondent was in his 30s with a stable job and relationship and extensive entheogen experience. Respondents tended to experiment with microdosing in phases, [...]

Lire la suiteToujours plus avec la chimie psychédélique par Thibault Henneton Manière de Voir (Le Monde Diplomatique), 2019, 163, Fruits d’une inventivité chimique sans limites, les nouveaux produits de synthèse (NPS) se sont multipliés ces dix dernières années, notamment dans les milieux festifs alternatifs. Moins chers que la cocaïne, ils restent difficiles à cerner tant pour les autorités que pour les usagers, incapables d’en connaître à l’avance les effets véritables, dont certains mènent aux hôpitaux, désarmés pour les traiter. Akatre ///// « Djeff », 2018 Placés récemment sous les projecteurs, les nouveaux produits de synthèse (NPS) inonderaient le marché des stupéfiants.

Lire la suitePositive psychology in the investigation of psychedelics and entactogens : A critical review Henrik Jungaberle, Sascha Thal, Andrea Zeuch, Ansgar Rougemont-Bücking, Maximilian von Heyden, Helena Aicher, Milan Scheidegger Neuropharmacology, 2018 PII: S0028-3908(18)30336-8 DOI: 10.1016/j.neuropharm.2018.06.034 Rationale : We reviewed the concepts and empirical findings in studies with psychedelics and entactogens related to positive psychology – the study of healthy human functioning, well-being and eudaemonia. It is an unresolved question how beneficial effects of psychedelics and entactogens are related to the potential risks of these substances – particularly in non-clinical settings. Methods : We searched in PubMed, PsychINFO and the Cochrane Library for controlled clinical and epidemiological studies [...]
Lire la suite“Microdosers” of LSD and magic mushrooms are wiser and more creative. Anderson T., Petranker R. The Conversation, 2018 Available from: http://theconversation.com/microdosers-of-lsd-and-magicmushrooms- are-wiser-and-more-creative-101302 We just ran the first ever pre-registered scientific study on the microdosing of psychedelics and found some very promising results. We compared people who microdose — that is, who take a psychedelic substance such as LSD (lysergic acid diethylamide) or “magic” mushrooms (psilocybin) in very small quantities — with those who don’t, and found that microdosers had healthier scores on key mental health and well-being measures. Specifically, we found that microdosers scored higher on measures of wisdom, open-mindedness and creativity. Microdosers also scored lower on measures [...]

Ayahuasca induces a modified state of awareness through the combined action of its active principles: the psychedelic N,N-dimethyltryptamine (DMT) and a series of centrally acting b-carbolines, mainly harmine and tetrahydroharmine. To better understand the therapeutic potential of [...]
