Massachusetts' advertising against light cigarettes appears to change beliefs and behavior

Objectives: This study examined the effects of advertising directed against light cigarettes (lights). Methods: In a quasi-experimental post-test-only design, smokers and ex-smok ers (sl year) in Massachusetts (MASS) (N=500) and the continental United St ates (U.S.) (N=501) took part in random-digit dialing telephone interviews. We used multiple logistic regression analyses to control for gender, educa tion, and age effects. Results: Compared with the U.S., the MASS sample contained more, recent ex- smokers (10% vs. 7% in the U.S.) and more smokers of higher tar cigarettes (44% vs. 35% smokers of regular cigarettes); more U.S. respondents thought lights had at least a slim chance of reducing the risk of health problems ( 49% vs. 32%). Within MASS, smokers who saw anti-light ads were less likely to think lights decreased the risk of health problems (26% vs. 44%) and mor e likely to know of filter vents (64% vs. 47%). These effects remained stat istically reliable after adjusting for confounders. Conclusions: Amidst extensive anti-smoking efforts, the MASS campaign to co unter-market light cigarettes appears to promote smoking cessation and to i nform smokers of the risks of light cigarettes. Further counter-marketing e fforts should be encouraged.
