Medical cannabis use

Abstract

Kevin Boehnke and coauthors (Feb2019) describe the indications of li-censed medical marijuana users inseveral states and compare those in-dications to evidence of efficacy. Ac-cording to estimates from the Nation-al Survey on Drug Use and Health(NSDUH) for 2013–15, in medicalmarijuana states, approximately 2.5 per-cent of Americans older than age twelveused medical marijuana in the pastyear.1However, the authors’results im-ply that medical marijuana use—at least,licensed use—is much less commonthan the NSDUH reports. Within eigh-teen states studied for 2016, they foundjust 641,176 licensed medical marijuanausers (0.4 percent prevalence).
