Expert reaction to two new papers – investigating frequency of e-cigarette use and smoking reduction or cessation, and investigating frequency and type of e-cigarette use and quitting smoking.

“These two new studies make valuable contributions to the growing literature on e-cigarettes. Most previous studies have been cross-sectional surveys using broad definitions of use, whereas these new studies are longitudinal in nature so are more able to follow up individuals. Commonly previous studies have asked whether e-cigarettes have ever or recently been used, and have made broad assumptions about their impact on quit attempts and success in stopping smoking on that basis. Most previous studies have also not differentiated between types of e-cigarettes, whereas the second of these studies does investigate that aspect.

“What this new research tells us is what e-cigarette users already know. The type of device, how often it is used, and how much nicotine it contains, all matter. Some devices will be effective to help smokers to quit and others less so. Future studies need to maintain this focus and not treat all e-cigarettes, or all users, the same.”

Prof. Linda Bauld, Deputy Director, Professor of Health Policy, University of Stirling.
