Frankly, If I can't smoke somewhere, I don't vape there either.
Here comes my outspoken self
Everyone who transitioned from smoking to vaping is generally in agreement that they are a lot better off. It's only logical given all the crap in modern processed tobacco. Congrats to everyone for no longer willfully ingesting cyanide and industrial solvents. That's all good.
Unfortunately, that seems, in some cases to give a false sense of entitlement, most based on logical fallacies apparrently hinging on "I was emitting 4300 toxins, now I'm not; so don't worry about it".
As far a I know there is no research that says that my exhaled vape has ZERO,
and I mean ZERO, not marginal, second hand impact. Until there is, I consider my vape an intrusion into someone else's personal space. That, and someone just might not like the smell of my mix.
Ergo, I do it where it would be generally be allowed, and simply don't stealth.
