Question Is e-cigarette use associated with discontinuation of cigarette use among smokers initially not planning to ever quit?
Findings In this US nationally representative cohort study of 1600 adult daily cigarette smokers who did not initially use e-cigarettes and had no plans to ever quit smoking, subsequent daily e-cigarette use was significantly associated with an 8-fold greater odds of cigarette discontinuation compared with no e-cigarette use.
Meaning These findings call for consideration of smokers who are not planning to quit when evaluating the risk-benefit potential of e-cigarettes for smoking cessation in the population.
