About The Study: The results of this study showed that adults ages 18 to 49 reporting medical-only or medical-nonmedical cannabis use vs nonmedical-only use had higher prevalence of cannabis use disorder at all severity levels and reported more frequent cannabis use. These findings suggest that medically recommended cannabis is not associated with reduced addiction risk compared with nonmedical use.
