Medical Research: What is the background for this study? What are the main findings?
Dr. Delnevo: We analyzed data from the 2014 National Health Interview Survey (NHIS) to examine how e-cigarette use differs by demographic subgroups and smoking status. We found that daily e-cigarette use is highest among former smokers who have quit in the past year. These recent quitters were four times more likely than current smokers to be daily e-cigarette users. Furthermore, regular use of e-cigarettes is rare among those who have never smoked and former smokers who have quit more than a year ago. This suggests that many smokers may be using e-cigarettes to quit, and that the devices are neither attracting nonsmokers nor leading to smoking relapse among long term former smokers. If e-cigarettes continue to be used as a smoking cessation tool and uptake among nonsmokers remains low, they may generate public health benefits.
