State Variation in U.S. Medical Cannabis Limits, Restrictions, and Therapeutic Cannabis Dosing

Abstract Wide variation exists in the possession limits of cannabis products sold for medical use in the U.S. as well as the tetrahydrocannabinol (THC) content of cannabis products. Prior work has found that legal limits on recreational cannabis sold per transaction may promote moderate use and diversion. This paper finds similar results for monthly medical cannabis limits. In the present analyses, state limits on medical cannabis were aggregated and converted into 30-day limits and 5 milligram (mg) THC doses. Grams
