Last week, the government unveiled a series of proposed warning labels for cigarette packs (pdf) marketed in the United States. Many of the images are disturbing, featuring drawings or photographs of diseased lungs, a corpse, a man smoking a cigarette through a tracheotomy tube and rotting teeth. Are these new labels likely to encourage smokers to quit or prevent teens from becoming smokers? And how are we doing on the war against tobacco use? We talk with JOSEPH CAPPELLA, communications professor at Penn’s Annenberg School for Communication, whose research focuses on the development and effectiveness of anti-smoking messages. Then, MATTHEW MYERS of the Campaign for Tobacco-Free Kids joins us to talk about the strategies tobacco companies are using here and abroad to keep people smoking.
