Cannabis : quels examens biologiques en milieu hospitalier ?

摘要

The blood pharmacokinetics of tetrahydrocannabinol (THC) is different between occasional users (CO) and chronic users (CC) for the some absorbed dose of cannabis. Inhalation of cannabis leads to a rapid rise in THC in the blood with a maximum concentration obtained 5 minutes after the end of consumption, then decrease and disappear about 6 hours after in OC and more than 24 hours after in CC. Elimination is in the form of urinary THC-COOH, the ultimate metabolite of THC, which persists for several days in the urine.
