British health officials said Wednesday that e-cigarettes are about 95 percent less harmful than smoking and added that they do not serve as a gateway or "route into smoking for children or non-smokers."

There's plenty of competing literature about the hot-button issue as vaping, or using e-cigarettes, has been growing in popularity across the globe.

The study—which e-cigarette advocates suggested should go a long way in preventing harsh regulations in the UK and getting them instead used to help smokers quit—contradicts a 2014 report by the World Health Organization. The WHO report called for major regulation of e-cigarettes as well as a ban on their use indoors and sales to minors. What's more, University of Southern California researchers announced days ago that teens in the US who use electronic cigarettes have a strong possibility of using regular cigarettes.

The UK decision comes as US health officials are moving to regulate e-cigarettes.

I don't smoke, so I have no horse in this race. If you use E-cigs, how do you feel about this study and the other conflicting studies?
