Hi Michael I'm not sure exactly what you're asking. Smokers were not randomly assigned to watch or not watch the ads so in that sense it is not possible to determine causality. The researchers compared population levels of smoking and quit attempts before and after the campaign. http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2813%2961686-4/fulltext

Quotes: "According to a new study published on Monday in The Lancet, the ads may have prompted more than 100,000 Americans to give up smoking for good. The study, led by a team at the Centers for Disease Control and Prevention, surveyed 5,300 Americans before and after the campaign, including 3,000 smokers. The paid ads ran for three months beginning in March, just after the New Year resolution season, when the percentage of smokers trying to quit is typically on the decline. The researchers found that over all, four of five of smokers had seen the commercials, and the percentage who reported trying to quit rose by 12 percent. Of those who tried to quit, about 13 percent remained abstinent after the campaign had ended." Does anyone have a reference for the research psychologists have done to show that these ads don't have a causal effect on smoking cessation? Michael A.
