In this crossover study, participants completed four three-hour treatments in random order, separated by at least 72 hours: oral placebo plus smoked/vaporized placebo, oral cannabis (in the form of a fudge brownie) plus smoked/vaporized placebo, oral placebo plus smoked cannabis, and oral placebo plus vaporized cannabis. The oral treatment was given first, and the smoked/vaporized treatment was given 10 minutes later. In each treatment, the participants received about 50 mg THC.
Blood was drawn twice prior to receiving the treatment, and 5, 15, and 1 hour and 20 minutes after smoked or vaporized cannabis was administered, or 25, 40, and 1 hour and 40 minutes after oral cannabis was administered.
