Evaluation of the Value of Varying E-cigarette Product Characteristics Across Different Populations: A conjoint analysis of 6 product characteristics among youth and young adults
Aim 1: To characterize the relative importance and price utility of product attributes (flavor, packaging, nicotine formulation, warning label size, device type, price) and levels within each attribute among participants with any history of e-cigarette use or use of another tobacco product.
Aim 2: To evaluate whether outcomes described in Aim 1 differ between youth nonsmokers and young adult smokers. Secondary analyses will evaluate whether outcomes also differ by race/ethnicity, LGBTQ+ status, gender, frequency of e-cigarette use, history of other tobacco use, and nicotine dependence, to provide evidence regarding the impact of such features on vulnerable populations with a disproportionate share of the tobacco related disease burden.
Effects of Ice Flavors and Nicotine on E-Cigarette Product Appeal and Likelihood of Future Use in Adults
To test the hypothesis that there will be a main effect of flavor on appeal and intention to use, that there will be an interaction between ice flavor status and nicotine concentration, and to determine if there are effects of tobacco product user status.
To assess the effect of provision of IQOS, evaluate shifts in product perceptions and examine the acute changes via EMA/mobile spirometry in pulmonary functioning upon switching from combustible cigarettes to IQOS.
Evaluating the Influence of Local Flavored E-cigarette Sales Restrictions on E-cigarette and Other Tobacco Use Outcomes Among Vulnerable Populations
To examine the influence of FESRs on e-cigarette use, other tobacco use, and tobacco purchasing location among the historically targeted vulnerable populations
