Association of Naturalistic E-Cigarette Use and Smoking Cessation in U.S. Adults.

ABSTRACT: Temporal imprecision and unaddressed confounding limit inferences whether e-cigarette vaping provides real-world benefits or harms for combustible cigarette smoking cessation. This naturalistic, multilevel longitudinal study of US adults examined whether (semi-)monthly transitions in e-cigarette vaping were associated with attaining smoking abstinence and subsequent post-quit relapse. A nationally representative panel of 1,255 adults who smoked at baseline completed up to 22 bi-weekly and 13 monthly surveys between May 2020 and May 2022. Using multilevel longitudinal models, we assessed within-person transitions in past-7-day vaping status (none, non-daily, daily) as time-lagged, time-varying predictors of 7-day point-prevalence smoking outcomes (0 vs. 1-7 days). Results showed that daily
