We should take advantage of the greater ease of conducting rigorous research on the benefits and harms of cannabis use after legalization. This needs to be performed in ways that minimize the undue influence that commercial interests have had on research on the adverse effects of alcohol and tobacco. The goal should be to advise governments on how to regulate legal cannabis markets in ways that minimize the harms of the regular use of high-potency products while maximizing the social and medical benefits of adult use under cannabis legalization.
