Tobacco Constituent Messaging Tactics (IMAGE) UNC Lineberger Comprehensive Cancer Center Caption The study tested three conditions— two were experimental and one was the control — with messages on chemicals in cigarettes sent to participants for 15 consecutive days. The first message included a graphic image of a person with a health issue, information on a chemical in the tobacco, a related health problem, a toll-free quit line and the FDA logo. The second included a graphic image of person with a health issue and a tobacco constituent message but not an FDA logo or any quit line information. The third, the study control, included only an image of cigarette butt litter and a message reminding people not to litter.
