Adolescents who watch movies that show smoking are more likely to become smokers.

A national study found that teenagers who have high exposure to smoking through movies are three times more likely to smoke than teens who don't watch movies with smoking. Interestingly, the effect watching movies with smoking is greatest among teens who are traditionally considered low-risk, such as those whose parents don't smoke.

PositiveTip: Monitor the movies your kids watch. If there's smoking, don’t let them watch it! No kidding!
