A lot of e-cigarette smokers have decided that the benefits outweigh the risk. But there are also a lot of folks who are opposed to the whole idea of e-cigarettes. Some of those folks are in government and some are affiliated with special interest groups.
The idea of exploding e-cigs is frightening. But there's something missing from the news reports. They need to name names. If it were any other industry, eager reporters would be investigating the hell out of this. And specific companies would be identified and pilloried in the press.
The media are willing to blame Russia for tampering with the presidential election without having seen any proof. But they really dropped the ball on the case of the exploding e-cigarettes.
