The problem with this crap is that no one really knows. Common sense would tell you that E-cigarettes if popular, are a threat to two parties. Two very powerful parties. The cigarette companies, and the patches, gums, and all the other quit smoking aids by big pharma. Obviously, E-cigs are not going to be welcome, and if the FDA can muster up any kind of statistic to make E-cigs sound bad, they will do it for sure.
However, Being that we really do know very little about the true effects of vaping, we really do not know the relative saftey either. So it is basically what side do you want to believe? Maybe E-cigs will really turn out just as bad, however, I believe e-cigarettes might be the future of smoking. Perhaps in the future an interested party with money could produce an ecigarette, that is not just safer than cigarettes, but actually healthy for the body.
