Re: E-cigarette use and associated changes in population smoking cessation: evidence from US current population surveys

It is good to read this research article, “E-cigarette use and associated changes in population smoking cessation: evidence from US current population surveys”.

E-cigarette use is a health & social problem in populations all over the world, and the regulation of electronic cigarettes is required [1-3].

The strength of evidence of such large surveys is poor (bias at different levels is involved). The result that "substantial increase in e-cigarette use among adult smokers was associated with increase in the smoking cessation rate" is statistically significant but not clinically significant.

This population survey is a liberal approach to e-cigarette regulation [4], & does not support the use of e-cigarettes among adult smokers and to quit smoking.

Regards,
