A systematic study of microdosing psychedelics, Vince Polito & Richard J. Stevenson, 2019

A systematic study of microdosing psychedelics RESEARCH ARTICLE Vince Polito, Richard J. Stevenson PLoS ONE, 2019, 14, (2), e0211023. Doi : 10.1371/journal.pone.0211023   Abstract The phenomenon of ‘microdosing’, that is, regular ingestion of very small quantities of psychedelic substances, has seen a rapid explosion of popularity in recent years. Individuals who microdose report minimal acute effects from these substances yet claim a range of long-term general health and wellbeing benefits. There have been no published empirical studies of microdosing and the current legal and bureaucratic climate makes direct empirical investigation of the effects of psychedelics difficult. In Study One we conducted a systematic, observational investigation of individuals [...]

Bibliographie : Cannabis et Troubles cardio-vasculaires

Bibliographie Cannabis et Troubles cardio-vasculaires   Dr Christian SUEUR, GRECC, 2e édition, janvier 2020.   Actuellement, les méta-analyses ne montrent pas d'augmentation significative des pathologies cardiovasculaire chez les consommateurs de cannabis. (cf en particulier la méta-analyse de Divya RAVI et coll., Annals of Internal Medicine, 2018). Quoiqu'il en soit, l'existence de facteurs de risques liés à la consommation de cannabis fumé est semble-t-il incontestable; de même, les risques sont vraisemblablement augmentés chez les sujets prédisposés, présentant des pathologies cariaques, vasculaires, des troubles de l'excitabilité cardiaque ou de la tension artérielle. La plupart des "Case Report" consistent en des accidents par sténose vasculaire, cérébrale ou cardiaque, [...]
