Forty-seven percent of teens agreed that movies and TV shows make drugs seem like an OK thing to do, according to a 2011 study. Not surprisingly, 12- to 17-year-olds who viewed three or more “R” rated movies per month were seven times more likely to smoke cigarettes, six times more likely to use marijuana, and five times more likely to drink alcohol, compared to those who hadn’t watched “R” rated films (Amy Khan 2005).
