Bibliographie : 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 [...]

For this reason, CBD has become a primary focus of medicinal cannabis studies. CBD has been found to have a wide range of benefits, including lowering blood sugar levels, promoting bone growth, and importantly, protecting the human brain and nervous system from degeneration.
