Results (N = 1,016) indicated that e-cigarette users who joined user-created groups had significantly more negative attitudes toward quitting and lower behavioral control, intention to quit, and self-efficacy than those who were exposed to sponsored advertisements or who followed brand pages. Exposure to two or more types of marketing had an additive effect on health-related outcomes. Social identification, attention to social comparison, and subjective norms also moderated between exposure to e-cigarette marketing and key dependent measures.
