Summary
The aim of this study is to determine if graphic messages prevent future vaping use among African American and Latino adolescents. The images have been developed in a user-design model and include four main themes: health reward, financial reward, self-efficacy, and social norms. We will assess pre- and post-exposure reactions on likelihood of future vaping among African American and Latino adolescents.
