Rationale: In the United States (US), the number of adolescents and young adults (AYAs) who use electronic cigarettes (e-cigarettes) continues to increase, with estimates at 5.4 million new users in 2019. E-cigarettes are the most commonly used tobacco product among AYAs, but it is difficult disentangle the risk of asthma and related respiratory symptoms associated with e-cigarette use due to the frequency of co-use with combustible cigarettes and cannabis products. This study examined associations between e-cigarette, cigarette, and cannabis use and self-reported 1) asthma diagnosis, 2) shortness of breath (SOB), and 3) wheeze. Methods: A sample of US AYAs (N = 2931; Mean age=18.9 [SD=1.6]; 80% female; 75% white) provided cross-sectional, self-report data via a web-based survey from August 6 to 31, 2020. Questionnaires assessed AYA demographics (age, sex at birth, race/ethnicity), self-reported asthma diagnosis, frequency of respiratory symptoms over past 30 days (SOB, wheeze) and co-product use (e-cigarette, cigarette, and cannabis). Multivariable logistic regressions were used to evaluate the associations between past 30-day e-cigarette, cigarette, and cannabis use and asthma diagnosis, wheeze, and SOB. Results: The prevalence of asthma, wheeze, and SOB among AYAs was 24%, 13%, and 20%, respectively. Among past 30-day current e-cigarette users (n=1414), 15% reported current use of cigarettes and 37% reported cannabis use. After controlling for age, sex at birth, and race/ethnicity, past 30-day e-cigarette use was associated increased odds of self-reported asthma (Odds ratio (OR): 1.4, 95% CI:1.1 - 1.7), wheeze (OR:3.1, 95% CI:2.3 - 4.2), and SOB (OR:2.9, 95%CI:2.3 - 3.6), compared to never e-cigarette users. After controlling for past 30-day cigarette and cannabis use, past 30-day e-cigarette use was no longer associated with asthma (1.11, 95% CI:0.87-1.41), but still associated with increased wheeze (OR: 2.3, 95%CI: 1.6-3.0) and SOB (OR: 2.1, 95%CI:1.6-2.8). Conclusion: In this cross-sectional convenience sample of AYAs from the US, e-cigarette use was associated with increased risk of wheeze and SOB, after controlling for cigarette and cannabis use. Longitudinal studies are needed to further determine the long-term health effects of e-cigarette use and whether concurrent use with cigarettes or cannabis will increase the burden of respiratory disease.
