Anti-tobacco advertising campaigns are effective in increasing tobacco cessation. Research shows that campaigns that are combined with other activities to reduce tobacco use are effective in both reducing consumption of tobacco products and increasing cessation among smokers. Seven studies, which lasted two years or longer, evaluated campaigns to reduce tobacco use initiation. They observed a median decrease in tobacco initiation of 8.0 percentage points compared with groups not exposed to the campaign.
Studies evaluating the effectiveness of mass media campaigns in reducing tobacco consumption in statewide populations (as measured by statewide sales of cigarettes) found a median decrease of 15 packs per capita per year.
