Hello, I am curious as to the legality of "e-cigs" concerning minors. As far as I can tell, there's nothing illegal to these as they are just vaporizers and if I got nicotine-free cartridges I wouldn't be breaking any laws. I'm sure this is an age-old question here, but how safe is water vapor to inhale? I'm just a 16 year old "techie" and I think these look really neat and would give me something to do instead of nervously tapping on my desk and chewing my pens.
