“Cannabis is a recreational drug leading to intoxication, due to cannabinoid receptor one (CB1 ) stimulation. The aim of the study was to determine whether CB1 antagonism could reverse physical cannabimimetic effects. In this study, the pre-existing, central nervous system-related cannabimimetic effects, measured via the hypothermic effect, induced by CB1 receptor agonism where therapeutically treated and were rapidly reversed by CB1 receptor antagonism/inverse agonism. There was also a subjective reversal of visually-evident sedation.
