I am not a smoker or vapor person. Federal regulation is in in infancy, and so far most if not all vape brands can not advertise themselves as safer because they have not done a study. The products you buy may not be pure and every ingredient delivered is not studied for heath effects when delivered in vapor. So what you do with your body is your business, IMHO you do not need vapor for nutrition and should avoid it. Better than smoking? Many brands probably are, WE DO NOT KNOW. Lots of other things in the same category, many of which were tested, and the testers know no money can be made when they fail. Hummm.
