Brief Original ReportProfile of e-cigarette use and its relationship with cigarette quit attempts and abstinence in Kansas adults

- Kansas state-specific prevalence of cigarette, e-cigarette and dual product use
- Adults who only use e-cigarettes tend to be younger and more affluent than cigarette smokers.
- Use of e-cigarette and smokeless tobacco as smoking cessation aids is common.
- E-cigarette use is positively associated with cessation behavior, but negatively associated with cigarette abstinence.

ObjectiveThe aim of this study is to describe electronic cigarette use in Kansas adults and its relationship with cigarette cessation.MethodsThe Kansas Adult Tobacco Survey (ATS) is a 2012-2013 phone survey of non-institutionalized Kansas adults (N = 9656). The ATS was analyzed to create a profile of cigarette and e-cigarette users, and demonstrate associations between e-cigarette use and cigarette cessation attempts and cigarette abstinence.ResultsIn 2013, 45% of adult cigarette smokers had tried e-cigarettes and 14% had used e-cigarettes in the past month. The prevalence of current cigarette smoking was 76.5% among past-month e-cigarette users. Adults who only use e-cigarettes are younger and more affluent than adults who only smoke cigarettes. The prevalence of past-month e-cigarette use among smokers who made a quit attempt in the past year is more than double that of smokers who did not. E-cigarette use was negatively associated with past-month (aPOR = 0.21, 95% CI: 0.11-0.38) and past-year cigarette abstinence (aPOR = 0.14, 95% CI: 0.10-0.22).ConclusionsE-cigarette use is common among cigarette smokers. E-cigarette use is more common among smokers who made a recent quit attempt and many smokers report using smokeless tobacco or e-cigarettes to help quit. Recent cigarette abstinence, however, is negatively associated with e-cigarette use.
