Abstract

Electronic (e)-cigarette use has increased markedly across groups in the past few years. For this reason, risk factors associated with e-cigarette use warrant further research. This study presents secondary data analyses on e-cigarette use from a large cross-sectional database assessing attitudes toward a tobacco-free campus (TFC) policy prior to policy implementation (n = 1188), one-month post policy (n = 1442), and one-year post policy(n = 1125). Students from a U.S. university located on the border with Mexico (M_age = 25.02 years, SD = 7.99; 59.2% female) were recruited via email to complete an online assessment of their tobacco use, attitudes toward TFC policies, perceived problematic tobacco use, and knowledge of tobacco use risk. The prevalence of any past-30-day e-cigarette use significantly increased from 4.4% to 26.6% between baseline and one-month post-policy, and reduced to 17.3% between one-month post-policy and one-year post policy. Weekly alcohol use was associated with e-cigarette use at each assessment point. There was some evidence of higher e-cigarette use among younger students and current smokers. Additional studies are needed to understand the influence of comprehensive TFC policies on both e-cigarette use and polysubstance use (i.e., alcohol and combustible cigarettes).
