Graphic and/or emotional television anti-smoking ads get more smokers to try to quit than less intense ads, according to a new study in the American Journal of Preventive Medicine.

"Harder hitting worked equally well, regardless of how much you wanted to quit, how much your income is and your level of education," said Matthew C. Farrelly, Ph.D., chief scientist at RTI International in Research Triangle Park, N.C., and lead author on the study.

The study evaluated the impact of anti-smoking ads run by the New York from 2003 to 2011. Smokers were surveyed about their smoking habits, their recall of anti-smoking ads, their desire to quit and demographic information, such as income level and race.
