Marijuana affects more than just a teen’s developing brain and health. Frequent use of the drug can have long-term effects on a teen’s life goals.
Daily marijuana users were 60 percent less likely to graduate high school and college than students who never used the drug, according to a study published last week in The Lancet Psychiatry, a journal covering health research.
"Dropping out of school is a big deal for a kid and that really changes someone's life," says Keith Humphreys, a psychiatry professor at Stanford University.
The same study also found that daily teen users were seven times more likely to attempt suicide.
