The study, “Trends in Tobacco and Alcohol Brand Placements in Popular US movies, 1996 through 2009,”was published online in the May 27, 2013 JAMA Pediatrics. Studies have shown that movies influence smoking and drinking during adolescence: A 2012 Surgeon General's report noted a causal relationship between the initiation of smoking in adolescents and depictions of smoking in movies, and there are studies showing that children's exposure to movie imagery of tobacco and alcohol is also associated with early onset of drinking and alcohol abuse.
