Commentary on Brose et al. (2015): Protecting individual and public health by regulating electronic cigarette nicotine delivery.

The article discusses the regulation of electronic cigarette (e-cig) nicotine delivery. It responds to the article "Is the use of electronic cigarettes while smoking associated with smoking cessation attempts, cessation and reduced cigarette consumption? A survey with a 1-year follow-up " by Leonie S. Brose and colleagues, which appears elsewhere in the issue. According to the authors, e-cig use does not help most tobacco smokers quit smoking. The marketing of e-cigs is also discussed.
