Researchers at the Dartmouth Medical Center in New Hampshire have found that attractive ads featuring cigarette influence teens to take up the habit.

At the start of the study the students were shown 12 ads with branding removed. Six of the ads were of cigarettes and the remaining were of other products. After nine months, some 13% started smoking.
"There is a mental model for how advertising works. After viewing an ad, teens start having favorable thoughts about smoking: 'it might be fun, it might make me more socially accepted.' This preceded any intent to smoke on their part," said study co-author Dr. James D. Sargent, a professor of pediatrics and family and community medicine at Dartmouth Medical Center in New Hampshire.
The study is due to be printed in the February issue of Pediatrics.
