Abstract
OBJECTIVES: Describe e-cigarette sales trends and market share from U.S. convenience stores and mass market retailers. METHODS: We used Nielsen Scantrack to calculate U.S. e-cigarette sales market share from convenience and mass market channels during the 4-week period ending 1/19/13 through the period ending 12/19/15. Internet searches were used to supplement Nielsen product information. RESULTS: From 2013 to 2015, rechargeable e-cigarette brands VUSE and MarkTen experienced the largest growth in Nielsen channels. E-liquid and tank type brands Vapin Plus and Haus experienced growth although their Nielsen market share is small compared to other brands. Sales of brands with high labeled nicotine content (according to packaging or website) increased. Fruit-flavored sales increased rapidly in Nielsen, yet still represent a minority of market share in these channels. DISCUSSION: 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.
