Reported effects of psychedelic use on those with low well-being given various emotional states and social contexts Natasha L. Mason, Patrick C. Dolder and Kim P.C. Kuypers Drug Science, Policy and Law, 2020, Volume 6, 1–11. Doi : 10.1177/2050324519900068   Abstract Background : It has been suggested that the outcome of the psychedelic experience is dependent on set and setting.

It was aimed to assess under which emotional and environmental circumstances psychedelic users use psychedelics, and the outcome [...]

Species-specific susceptibility to cannabis-induced convulsions, Benjamin J Whalley et al., 2018

Species-specific susceptibility to cannabis-induced convulsions Benjamin J Whalley, Hong Lin, Lynne Bell, Thomas Hill, Amesha Patel, Roy A Gray, C Elizabeth Roberts, Orrin Devinsky, Michael Bazelot, Claire M Williams and Gary J Stephens British Journal of Pharmacology, 2018, 1-18. Doi : 10.1111/bph.14165   BACKGROUND AND PURPOSE Numerous claims are made for cannabis’ therapeutic utility upon human seizures, but concerns persist about risks. A potential confounder is the presence of both Δ9-tetrahydrocannabinol (THC), variously reported to be pro- and anticonvulsant, and cannabidiol (CBD), widely confirmed as anticonvulsant. Therefore, we investigated effects of prolonged exposure to different THC/CBD cannabis extracts on seizure activity and associated measures of endocannabinoid [...]

Le cannabigerol est efficace contre les infections par des bactéries résistantes aux antibiotiques, The Guardian du 19 Janvier 2020

Le cannabigerol est efficace contre les infections par des bactéries résistantes aux antibiotiques Le cannabigérol (CBG), un cannabinoïde de la plante de cannabis, s’avère pouvoir détruire les bactéries résistantes aux médicaments, suscitant l’espoir d’une nouvelle arme dans la lutte contre les superbactéries. Les scientifiques ont examiné cinq cannabinoïdes pour leurs propriétés antibiotiques et ont découvert que le cannabigérol (CBG) était particulièrement puissant pour tuer le Staphylococcus aureus résistant à la méthicilline (SARM), l’une des super-bactéries les plus courantes dans les hôpitaux. Après avoir vu l’efficacité de la substance contre les bactéries en laboratoire, les chercheurs ont décidé de tester la capacité du [...]

Psychedelics and potential benefits in “healthy normals”: A review of the literature Sam GANDY Journal of Psychedelic Studies, 2019, 3, (3), 280–287. Doi : 10.1556/2054.2019.029   We are in the midst of a psychedelic research renaissance. With research examining the efficacy of psychedelics as a treatment for a range of mental health indications still in its early stages, there is an increasing body of research to show that careful use of psychedelics can yield a variety of benefits in “healthy normals” and so lead to “the betterment of well people.” Psychedelics have been found to modulate neuroplasticity, and usage in a supportive setting can result [...]
