Is vaping itself harmful?

135. I'm new here so I'll try not to aggravate anyone, but as an ex-smoker who

did tons of research and actually used e-cigs to stop smoking cigarettes, I find it somewhat bewildering that people attack it so viciously.
I believe it to be a true statement when I say that inhaling anything that's not air is probably no *good* for you.
But if it helps people stay off of tobacco, it's a gift to humanity. The exhaled residue is nothing more than glycol fog which is mostly just water, with minute trace amounts of leftover nicotine and flavorings. All of these things are practically harmless to bystanders other than the visual.
Nicotine in itself, although highly addictive, is no more harmful than caffeine.
If someone wasn't a smoker and I saw them picking one up, I would cry foul and make every attempt I could to get them to re-think such a foolish decision. But as promoters of better public health, we should be cheerleading for e-cigs and what they can accomplish for both smokers and those who hate being around them.
To frame it, if I had to catch my own kids doing one or the other, not that I would condone such behavior either, I'd much rather it be e-cigs than cigarettes or chewing tobacco.
