Legal marijuana: Risk for abuse among teens Unlisted Video

Nov. 13 (UPI) -- The legalization of recreational marijuana in some states has led to a slight uptick in reports of cannabis use disorder among teens, a new study suggests. In data published Wednesday in the journal JAMA Psychiatry, researchers report that rates of cannabis use disorder among Americans between the ages of 12 and 17 with a history of pot use increased from 2.18 percent to 2.72 percent from 2008 to 2016.
