A new study shows that the prevalence of marijuana use among U.S. adults has remained stable over the past decade, but the prevalence of marijuana abuse or dependence has increased significantly, possibly related to increased potency of the substance, according to a report in the May 5 issue of The Journal of the American Medical Association (JAMA).
