Objectives: Important differences exist between closed-system and open-system e-cigarettes, but it is unknown whether online companies are marketing these devices differently and whether consumer reasons for using e-cigarettes vary by device type. This paper compares Internet-based advertising claims of closed- versus open-system products, and evaluates US consumers' reasons for using closed- versus open-system e-cigarettes. Methods: Internet sites selling exclusively closed (N = 130) or open (N = 129) e-cigarettes in December 2013-January 2014 were coded for advertising claims...

OBJECTIVES: Beliefs that flavored smokeless tobacco (ST) is more pleasant, less potent, or otherwise easier to use could contribute to youth initiation. We evaluated associations between perceived ease-of-use of flavored ST (moist snuff and chewing tobacco) and ST initiation susceptibility in a representative sample of US youth. METHODS: Among 7,718 tobacco never-users in the Population Assessment of Tobacco and Health study (age: 12-17; collected: 2013-2014), we compared 4 ST susceptibility items (curiosity, expectation, willingness to try, and a composite) according to whether participants reported flavored ST to be "easier to use" than unflavored ST...

Wallace B Pickworth, Meridith Hill Thanner
OBJECTIVE: Domestic cigar use has increased over the past 2 decades perhaps partially in response to cigarette restrictions and partially because cigars are used as vehicles for the delivery of marijuana. Although there is ample epidemiologic data to verify use and use patterns, there are relatively few studies that have looked at other aspects of current cigar use, advertising, toxicant exposure, and health effects. METHODS: Gaps in knowledge prompted a research symposium entitled Cigar Use: Epidemiology, Toxicant Exposure, Health and Policy Implications in 2016...

OBJECTIVES: Behavioral economic purchase tasks, which estimate demand for drugs, have been successfully developed for cigarettes and are widely used. However, a validated purchase task does not yet exist for e-cigarettes. The aim of this project was to identify the relevant units for an e-cigarette purchase task (E-CPT). METHODS: Focus groups (N=28 participants in 7 groups, 2-7 participants per group) consisting of current e-cigarette users were conducted. Participants discussed their daily use patterns, completed a preliminary E-CPT which asked how many puffs of their e-cigarette they would consume per day at escalating prices, and discussed the extent to which the task accurately reflected their real-world behavior...
