Daily users of cannabis before age 17 are over 60% less likely to complete high school or obtain a degree compared to those who have never used the drug, a new review of literature shows. The authors reviewed 290 reports on cannabis use in teenagers published since 2004.
The authors conclude that adolescent cannabis use is linked to difficulties in successfully completing the tasks that mark the transition to adulthood.
