Content analysis of e-cigarette products, promotions, prices and claims on Internet tobacco vendor websites, 2013-2014.

ABSTRACT: OBJECTIVE:To identify the population of Internet e-cigarette vendors (IEVs) and conduct content analysis of products sold and IEVs' promotional, claims and pricing practices. METHODS:Multiple sources were used to identify IEV websites, primarily complex search algorithms scanning over 180 million websites. In 2013, 32 446 websites were manually screened, identifying 980 IEVs, with the 281 most popular selected for content analysis. This methodology yielded 31 239 websites for manual screening in 2014, identifying 3096 IEVs, with 283 selected for content analysis. RESULTS:While the majority of IEVs (71.9%) were US based in 2013, this dropped to 64.3% in 2014 (p<0.01), with IEVs located in at least 38 countries, and 12% providing location indicators reflecting two or more countries, complica
