I never said vaping is good for you. As you stated, the jury is still out on if and/or how bad it might be. It is known that the often touted FDA study is greatly flawed in both methodology and summary.<quoted text>
I agree... they almost have to be "better for you" than cigarettes.
However, the long term effects of inhaling chemically enhanced water vapor are still largely unknown. We will see if people aren't dropping left and right from pneumonia (or an offshoot there of) in 5-10 years.
Water and lungs don't get along very well either.
Actually, the main ingredients (propylene glycol and/or vegetable glycerin) have been used medically in nebulizers and inhalers for quite a long while and the flavorings are food grade, if you get the "ejuice" from reputable suppliers.
As far as water in the lungs, I live in Florida where the humidity is often 80% and I haven't keeled over yet.
