Constituent Message With FDA and Quitline
Messages about the chemical constituents of cigarette smoke will include text about chemicals in cigarette smoke and health effects of the chemicals, and an image of a person related to the health effect. This arm will also include an FDA logo, and information about the benefits of quitting smoking and the quitline. Each condition has 5 messages that will be repeated 3 times in a counterbalanced order.
