Product Characteristics, Marketing, and E-cigarette and Cigarette Use Across Adolescence and Young Adulthood
This project, known as TCORS Project 3, will test hypothesized e-cigarette product characteristics and marketing strategies that may attract never-smokers and put them at risk for tobacco product use but do not affect the likelihood that young smokers will adopt and switch to e-cigarettes. Examples of product features that may disproportionately attract never smokers (vs. smokers) include sweet flavors (vs. tobacco or other flavors), devices and e-liquid compositions used to generate large aerosol clouds for “vape tricks” (vs. devices that look and feel like cigarettes), and youth-oriented marketing strategies for e-liquid naming (such as “Kustard Killer”) and packaging with cartoon images. Researchers will survey participants in a cohort of adolescents and young adults (ages 14-25) in Southern California. Findings may inform future regulatory activities related to e-cigarettes.
Aim 1: To evaluate the associations of: (a) product characteristics and marketing exposure with e-cigarette interest, (b) e-cigarette interest with subsequent initiation, and (c) marketing exposure with subsequent initiation.
Aim 2: To evaluate the association of (a) e-cigarette initiation with cigarette initiation and progression, or discontinuation of tobacco product use, and (b) e-cigarette product characteristics and marketing exposure with dual use, nicotine dependence, or discontinuation of tobacco product use.
Aim 3: To evaluate whether associations of product characteristics and marketing with outcomes observed in Aims 1 and 2 differ between baseline never-smokers and smokers.
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
