過去5年間に禁煙を試みた798名を分析した結果,電子タバコを使用した人は、電子タバコを使用しなかった人よりもタバコをやめられた人が約3分1少なかったとのことです.

Abstract: The benefit of electronic cigarettes (e-cigarettes) in smoking cessation remains controversial. Recently, e-cigarettes have been gaining popularity in Japan, without evidence of efficacy on quitting cigarettes. We conducted an online survey to collect information on tobacco use, difficulties in smoking cessation, socio-demographic factors, and health-related factors in Japan. Among the total participants (n = 9055), 798 eligible persons aged 20–69 years who smoked within the previous five years were analyzed to assess the relationship between the outcome of smoking cessation and quitting methods used, including e-cigarettes, smoking cessation therapy, and unassisted. E-cigarette use was negatively associated with smoking cessation (odds ratio (OR) = 0.632; 95% confidence interval (CI) = 0.414–0.964) after adjusting for gender, age, health-related factors, and other quitting methods. Conversely, smoking cessation therapy (i.e., varenicline) was significantly associated with smoking cessation (OR = 1.885; 95% CI = 1.018–3.492) in the same model. For effective smoking cessation, e-cigarette use appears to have low efficacy among smokers in Japan. Allowing for the fact that this study is limited by its cross-sectional design, follow-up studies are needed to assess the prospective association between e-cigarette use and smoking cessation.

5. Conclusions
E-cigarette use was negatively associated with smoking cessation after adjustments for gender, age, health-related factors, and other cessation methods. Conversely, medical cessation therapy (i.e., varenicline) covered by the National Health Insurance program in Japan was significantly associated with smoking cessation in the same model. Since there is no present scientific consensus that e-cigarettes are beneficial for smoking cessation, any recommendation or promotion of e-cigarettes as a smoking cessation aid should be made with caution. Without strong evidence that e-cigarettes are efficacious in helping people to quit smoking, recommending them in the current manner is premature.
