Dual users of e-cigarettes and cigarettes may represent a unique and receptive population for evidence-based tobacco dependence treatment. We measured the frequency of quit attempts during the past year, and the use of evidence-based tobacco dependence treatments (i.e., behavioral and/or pharmacological treatments), among adult smokers who are current e-cigarette users (dual users) compared with those who do not use e-cigarettes (exclusive smokers). Data were analyzed from the 2015 National Health Interview Survey. Multivariate-adjusted regression models were used to examine the correlates of tobacco treatment use among adult smokers, comparing current e-cigarette users with those who did not use e-cigarettes, stratifying by age group, and adjusting for sociodemographic characteristics. Analyses were based on 5415 adult current cigarette smokers. Compared to exclusive smokers, dual users were more likely to report a quit attempt in the past year among adults <65 years: 18-24 years (odds ratio [OR] = 2.25), 25-44 years (OR = 1.60), and 45-64 years (OR = 1.96). With the exception of adults ≥65 years, dual users reported low rates of using combination (behavioral and pharmacological) treatments that were not statistically different from exclusive smokers: 18-24 years (0.1% vs. 2.1%, respectively), 25-44 years (4.3% vs. 4.7%), and 45-64 years (3.0% vs. 8.3%). Despite higher likelihood for dual users to make a quit attempt, their use of evidence-based tobacco treatment is low, similar to exclusive smokers. Dual users of cigarettes and e-cigarettes represent a prime target for interventions to expand access and utilization of evidence-based tobacco use treatments.
