Positive subjective experiences at e-cigarette initiation were found to predict increased odds of subsequent past 30-day e-cigarette use, as well as a greater relative risk of dual/poly vs. non-use and exclusive e-cigarette use. This study underscores the importance of preventing initial e-cigarette use among adolescents.
Background: Subjective experiences (SEs) at initiation of cigarettes, cigars, and smokeless tobacco have been established as predictors of continued use. To date, less is known about the relationships between SEs at ecigarette initiation and subsequent e-cigarette use behaviors. Methods: This study used data from Waves 1-6 of the Texas Adolescent Tobacco and Marketing Surveillance (TATAMS) system; a population-based rapid response study of adolescents in major metropolitan areas of Texas. Participants were adolescents who self-reported ever using e-cigarettes across all 6 waves (n = 1,104; N = 460,069). Factor analyses examined structure of SEs at e-cigarette initiation. Weighted, multilevel, multivariate regression models examined role of SEs at e-cigarette initiation on subsequent past 30-day e-cigarette use behaviors. Results: Factor analyses identified a positive (i.e., euphoria, relaxation) and a negative (i.e., dizziness, cough, nausea) domain of SEs. Positive SEs at e-cigarette initiation predicted 1.20 (95% CI: 1.02-1.42) greater odds of subsequent past 30-day e-cigarette use. Similarly, positive SEs at e-cigarette initiation predicted greater relative risk of dual/poly e-cigarette use, relative to non-use (RRR: 1.61; 95% CI: 1.24-2.10) and exclusive e-cigarette use (RRR: 1.68; 95% CI: 1.26-2.24). Conclusion: This is the first study to observe longitudinal relationships between SEs at e-cigarette initiation and subsequent e-cigarette use behaviors. Findings highlight the importance of preventing initial e-cigarette use among adolescents.
