Rapid Response Projects

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

PI: Jessica Barrington- Trimis, Ph.D.

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.

Adverse Outcomes Associated with E-cigarette Device Type Among Youth and Young Adults: A Pooled Analysis Across 3 Tobacco Centers of Regulatory Science

PI: Jessica Barrington- Trimis, Ph.D.

Aim 1: To evaluate the association of e-cigarette device type with symptoms of nicotine dependence using combined cross-sectional data from all three centers.

Aim 2: To evaluate the association of e-cigarette device type with progression to more frequent e-cigarette use and with initiation of other tobacco product use (including dual/polytobacco product use) using combined prospective data.

Aim 3: To evaluate the association of e-cigarette device type (vape pen vs. mod vs. JUUL or other pod products) with adverse respiratory health symptoms (e.g., symptoms of asthma or bronchitis) using combined cross-sectional data.

Evaluating the Influence of Local Flavored E-cigarette Sales Restrictions on E-cigarette and Other Tobacco Use Outcomes Among Vulnerable Populations

PI: Julia Chen-Sankey

Aim 1. To examine the influence of FESRs on e-cigarette use.

Aim 2. To examine the influence of FESRs on other tobacco use and tobacco purchasing location.

Aim 3. To examine the influence of FESRs among the historically targeted vulnerable populations.

Examining Risk Beliefs and IQOS Use Among Adults

PI: Alayna Tackett, Ph.D.

Aim 1: To assess the effect of provision of IQOS on substitution and/or co-use of usual brand cigarettes. Descriptive analyses of IQOS use over the 1-month observation period will be performed.

Aim 2: To evaluate shifts in product perceptions associated with switching from usual cigarettes to IQOS.

Exploratory Aim 3: To examine the acute changes via EMA/mobile spirometry in pulmonary functioning upon switching from combustible cigarettes to IQOS during the 1-month monitoring period.
