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 [...]

Or la recherche scientifique ne dispose pas de données fiables sur les véritables effets de cette substance, ni sur ses risques potentiels. Ursina s’est longtemps refusée à la tentation d’accompagner ses nuits festives de substances chimiques. «J’avais peur du mauvais trip», dit la Zurichoise de 40 ans, casquette et bomber satiné.
