Tobacco regulatory science

We examined the associations between socioeconomic status (SES) and adolescent polytobacco use profiles (including e-cigarettes and blunts). ⋯ Low SES is associated with membership in distinct polytobacco use latent classes. Regulatory initiatives that focus exclusively on cigarette use may miss the opportunity to influence adolescent use of other products, which may be especially relevant to low-income individuals. Future research should examine whether targeting a broader range of products reduces SES-related tobacco use disparities.

Describe e-cigarette sales trends and market share from U.S. convenience stores and mass market retailers. ⋯ Market-leading e-cigarette brands changed substantially in Nielsen channels from 2013 to 2015. Brand leaders in these channels are now owned by tobacco companies. Changes in labelled nicotine content and fruit-flavored products and product types suggest that as e-cigarette use increases, convenience store and mass market channels are offering new products to meet consumer preferences; however, Nielsen channels do not represent the entire e-cigarette marketplace.
