L’huile de chanvre contient-elle du THC et du CBD ?, Newsweed, 11 février 2020, Aurélien BERNARD

L’huile de chanvre contient-elle du THC et du CBD ? Newsweed, 11 février 2020 Aurélien BERNARD https://www.newsweed.fr/huile-chanvre-contient-thc-cbd/   L’huile de chanvre, extraite des graines, est une source précieuse d’omega 3 et 6 et de nutriments dans l’alimentation quotidienne. Sa valeur nutritionnelle et thérapeutique pourrait néanmoins aussi être attribuée à sa composition en cannabinoïdes qui, si faiblement présents, existent quand même. Dans une étude de 2019, plusieurs cannabinoïdes ont été détectés dans l’huile de graines de chanvre et permettent de déterminer des différences dans leur composition chimique. Bien que le CBDA et le CBD soient prédominants dans les dix huiles étudiées, 20 autres cannabinoïdes «mineurs» ont été [...]

Changing landscape of cannabis : novel products, formulations, and methods of administration, Tory R Spindle et al., 2019

Changing landscape of cannabis : novel products, formulations, and methods of administration Tory R Spindle, Marcel O Bonn-Miller and Ryan Vandrey Current Opinion in Psychology, 2019, 30, 98–102 Doi : 10.1016/j.copsyc.2019.04.002   Abstract Laws regulating cannabis have changed radically in the U.S. and abroad. Historically, users smoked dried cannabis flowers that contained D9-tetrahydrocannabinol (THC), the primary psychoactive component of cannabis, as the principal product constituent. Coincident with cannabis legalization and increased interest in medicinal use of the plant, there is now an expansive retail cannabis marketplace with novel cannabis products, formulations, and methods of administration. In this review, we describe emergent cannabis product chemotypes (e.g. THC-dominant, [...]

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, [...]

‘Standard THC units’: a proposal to standardize dose across all cannabis products and methods of administration, T.P. Freeman & V.Lorenzetti, 2019

'Standard THC units': a proposal to standardize dose across all cannabis products and methods of administration T.P. Freeman, V.Lorenzetti Addictions, 2019, Oct 12. doi : 10.1111/add.14842 © 2019 Society for the Study of Addiction. Abstract BACKGROUND AND AIMS : Cannabis products are becoming increasingly diverse, and vary considerably in concentrations of ∆9 -tetrahydrocannabinol (THC) and cannabidiol (CBD). Higher doses of THC can increase the risk of harm from cannabis, while CBD may partially offset some of these effects. Lower Risk Cannabis Use Guidelines currently lack recommendations based on quantity of use, and could be improved by implementing standard units. However, there is currently no consensus on [...]

CBD User’s Guide, ProjectCBD.org, 2019

CBD User's Guide Project CBD On March 13, 2018 (Updated on March 25, 2019) https://www.projectcbd.org/how-to/cbd-users-guide   Project CBD has created a beginner’s guide for cannabidiol & cannabis therapeutics to address key questions of CBD users. A Beginner’s Guide to CBD & Cannabis Therapeutics   In 2009, a handful of CBD-rich cannabis strains were discovered serendipitously in Northern California, America’s cannabis breadbasket, where certified patients could access medical marijuana legally. Thus began a great laboratory experiment in democracy involving CBD-rich cannabis therapeutics. The advent of whole plant CBD-rich oil as a grassroots therapeutic option has changed the national conversation about cannabis. It’s no longer a question of whether [...]

Acceptance of pharmaceutical cannabis substitution by cannabis using patients with schizophrenia Jan van Amsterdam, Jojanneke Vervloet, Gerdien de Weert, Victor J. A. Buwalda, Anna E. Goudriaan and Wim van den Brink Harm Reduction Journal, 2018, 15, 47, 1-4. Doi : 10.1186/s12954-018-0253-7   Abstract Background : Cannabis-smoking patients with a psychotic disorder have poorer disease outcomes than non-cannabis-smoking patients with poorest outcomes in patients smoking high-potency cannabis (HPC) containing high Δ9-tetrahydrocannabinol (THC) and low cannabidiol (CBD). Quitting cannabis smoking or substitution of HPC by cannabis variants containing less THC and/or more CBD may benefit these patients. The present study explores whether daily HPC-smoking patients with schizophrenia accept smoking [...]
