Loflin, Suman Chandra and Ryan Vandrey International Review of Psychiatry, 2018, VOL. 30, NO. 3, 277–284 Doi : 10.1080/09540261.2018.1474730 ABSTRACT Accumulating evidence suggests that the endocannabinoid system is a promising target for the treatment of a variety of health conditions. Two paths of cannabinoid drug development have emerged. One approach is focused on developing medications that are directly derived from the cannabis plant. The other utilizes a single molecule approach whereby individual phytocannabinoids or novel cannabinoids with therapeutic potential are identified and synthesized for pharmaceutical [...]

Del Bel; Francisco S. Guimaraes Behavioural Brain Research, 2016, 21. Doi : 10.1016/j.bbr.2016.04.042 Highlights Cannabidiol (CBD) attenuated haloperidol-induced catalepsy. CBD reduced c-Fos protein expression in the dorsal striatum induced by haloperidol. CBD effects were blocked by 5-HT1A receptor antagonist. Abstract Cannabidiol (CBD) is a major non-psychoactive compound from Cannabis sativa plant. Given that CBD reduces psychotic symptoms without inducing extrapyramidal motor side-effects in animal models and schizophrenia patients, it has been proposed to act as an atypical antipsychotic. In addition, CBD [...]

Bonn-Miller Addictive Behaviors, 2015, 50, 178–181 doi : 10.1016/j.addbeh.2015.06.032 a b s t r a c t Introduction : Individuals report using cannabis for the promotion of sleep, and the effects of cannabis on sleep may vary by cannabis species. Little research has documented preferences for particular cannabis types or cannabinoid concentrations as a function of use for sleep disturbances. Methods : 163 adults purchasing medical cannabis for a physical or mental health condition at a cannabis dispensary were recruited. They provided self-report of (a)whether [...]

Stouffer, Loren H. Parsons, Dana C. Hammell, Stan L. Banks, Audra L. Stinchcomb and Friedbert Weiss Neuropsychopharmacology, 2018, 43, 2036–2045. Doi : 10.1038/s41386-018-0050-8 Cannabidiol (CBD), the major non-psychoactive constituent of Cannabis sativa, has received attention for therapeutic potential in treating neurologic and psychiatric disorders. Recently, CBD has also been explored for potential in treating drug addiction. Substance use disorders are chronically relapsing conditions and relapse risk persists for multiple reasons including craving induced by drug contexts, susceptibility to [...]

The mechanisms of these beneficial effects of CBD are unknown. Here, we examined behavioral effects of CBD in a pharmacological model of schizophrenia-like cognitive deficits induced by repeated ketamine (KET) administration. In parallel, we assessed transcriptional changes behind CBD activities in the prefrontal cortex (PFC), the [...]
Lire la suiteBibliographie : Interactions et antagonisme THC - CBD Docteur Christian SUEUR, GRECC, mars 2020. Les interactions entre le THC et le CBD sur le système endocannabinoide, quant aux effets psychotomimetic (production de "symptomes psychotiques") sont opposés : là où le THC produit préférentiellement de l'anxiété, et des effets "psychotisants", le CBD est plutôt anxiolytique et "antipsychotique". Ces deux phytocannabinoïdes sont "antagonistes", et contribuent, parmi d'autres inter-relations entre les phytocannabinoïdes, les terpènes et les flavonoïdes composant le cannabis, aux "effets d'entourage" fondamentaux, tout autant quant à la production "d'effets indésirables" et de risques pour la santé mentale du consommateur, que dans le cadre de [...]
