The document discusses the effectiveness of the "truth" tobacco prevention media campaign for youth. It finds that the campaign successfully increased awareness of the dangers of tobacco use among 12-17 year olds. Surveys showed that 77-82% of youth found the ads convincing, attention-grabbing, and providing good reasons not to smoke. The campaign was also found to be cost-effective, at an estimated $1.38-$3.65 per youth reached. Expanding such campaigns, along with other prevention programs, was recommended to further reduce youth smoking rates.
