Trends in exposure to pro-tobacco advertisements over the Internet, in newspapers/magazines, and at retail stores among U.S. middle and high school students, 2000-2012

Exposure to pro-tobacco advertisements over the Internet increased significantly during 2000-2012 among United States middle and high school students, while a decline in exposure to advertisements in newspapers or magazines, and at retail stores occurred during the same period. However, over two-thirds of students still reported retail store exposure to pro-tobacco advertisements in 2012. Enhanced and sustained efforts would be beneficial to reduce even more exposure to all forms of pro-tobacco advertisements among youths.
