I'm seeing and hearing about more and more places not allowing vaping. I know WHY people don't want vaping, they don't understand what it is. My question is, would this be an issue if there was no visible vapor? People tend to blame it on the "smell" or that the second hand vape is somehow bad for them. What if they saw us sucking on a battery and blowing out nothing but "air". Would there be an issue? I think not.
