I'll stick my neck out and say that while I'm wholeheartedly opposed to banning e-cigs I'm also in favor of nicotine juice having to be ingredient-labeled, just as health food supplements and thousands of other things we consume are. I really don't know where the juice I order is manufactured, or under what conditions of cleanliness, or what is used in making it. I know analogs are no good for me because of the tar and chemicals in them, but I really can't say with any certainty that what I'm buying for my 510 is free of impurities or made with pharmaceutical grade glycol or glycerin.
The industry is very young, and most of the supplies, it seems, are still made overseas. I don't want to see this taken away just as I'm getting into it with high hopes, but at the same time I'd like to know that what I'm vaporizing contains only the stuff I'd welcome into my body. So, if that makes me sound willing to have some sort of regulation of the industry, so be it. Anyone can put on their label or web site a statement that something is made to "the highest standards", but really, at this time there are not really any standards as far as I can tell.
