Dual Use of Smokeless Tobacco or E-cigarettes with Cigarettes and Cessation

Objectives: To evaluate predictors of dual use of cigarettes with smokeless tobacco or e-cigarettes. Methods: Adult smokers (N = 1324) completed online cross-sectional surveys. Logistic regression evaluated predictors of dual use and cigarette quit attempts. Results: Smokeless tobacco dual use was associated with past attempts to quit smoking by switching to smokeless products. E-cigarette dual use was associated with using stop-smoking medication and strong antitobacco industry attitudes. Ever use of stop-smoking medication was associated with quit attempts among dual e-cigarette users and cigarette-only users. Conclusions: Dual users are more likely than cigarette-only users to endorse certain cessation-related attitudes and behaviors. This may provide an opportunity for clinicians or others to discuss evidence-based strategies for smoking cessation.
