Young adults' visual attention to features of social media marketing for disposable e-cigarettes and associated perceptions.

US young adults appear to be particularly visually engaged by disposable e-cigarette marketing that uses social media account features (account profile pictures, information about the products marketed and relevant hashtags) and features enhancing the products' personal relatability. Disposable product packages, fruit/candy descriptors and price promotions may increase the influence of social media marketing among various use status groups.
