Vaping a gateway to smoking tobacco?

Nicotine is probably the least harmful substance in e-juice.

@Feliks Karp I agree - but if a non-smoker takes up vaping, they shouldn't vape with nic. While nicotine is, as you say, the least harmful substance IN E-JUICE, it does have negative effects on the body.
 
@bjorncoetsee It's strange - I've read a number of comments that fitness - especially breathing - improves vastly after starting to vape. I wonder if you're not allergic to PG? I believe it happens to some people.
It increases for a smoker yes obviously. But for a non smoker, nothing u inhale is going to increase ur fitness
