Key Findings:  To study the urinary excretion level of 7 different metabolites of ∆9-tetrahydrocannabinol (∆9-THC), subjects were given either oral and vaporized cannabis or a placebo, at differing doses. Results suggest that additional analytes, not just standard ∆9-THC-COOH, may be worth investigating to elucidate better licit versus illicit cannabis consumption.
