This study aims to investigate the trends in e-cigarette use among U.S. adults from 2014 to 2023 based on various demographic factors.
Analyzed repeated, cross-sectional data from the Tobacco Use Supplement to the Current Population Survey (TUS-CPS) for specified years.
Applied self-response and replicate weights for national estimates and utilized predicted marginals for adjustments.
Assessed trends using linear contrasts.
Current e-cigarette use among U.S. adults rose from 2.22% (2014-2015) to 3.13% (2022-2023), p<0.01.
Increased use observed in Black non-Hispanic adults (1.02% to 1.69%, 65.69% increase) and Hispanic adults (0.93% to 1.48%, 59.14% increase).
A significant rise in e-cigarette use among young adults (18-24) who had never smoked, from 25.11% in 2014-2015 to 67.63% in 2022-2023.
