And when I was in school half the kids smoked cigarrettes. I have no idea what the numbers are, but you have to consider that fewer kids are using tobacco, which is a good thing.

Well, it depends.

As far as I remember, the vehicle is propylene glycol. It isn't biologically inert, and I'm not sure how much work has been done to study buildup within the lungs or combustion products. Combine that with dodgy sourcing allowing metal contamination.

It seems more or less the definition of trading the devil you know for one you don't.

There are a lot of studies about inhaling PG in the context of smoke machines (in bars, generally). It reduces lung function, but not permanently. No more serious harm seems to be indicated.

Also, PG has been used in ventilation systems as an air sanitizer for decades. Not a 1:1 comparison given the massively increased volume papers get, but it's something.

False dichotomy. Tobacco smoking was on a downwards trend before vaping anyhow (it just plain stopped being “cool”) so clearly you don’t need vaping as alternative to reduce tobacco usage.
