glad that there are people out there taking action.thanks for your service.
It doesn't matter for what they were "intended" to be used. There is no evidence that e-cigarette vapor poses a health risk to bystanders and the smoking ban was passed to protect the public from smoke, not vapor. They cannot just arbitrarily decide that vapor is the same as smoke because of what it looks like or why it's used. Otherwise, they are setting a precedent that they can forbid anything on the same grounds - "smokeless tobacco lozenges intended to circumvent the prohibition of smoking" (which also market with that selling point) or "nicotine gum intended to circumvent the prohibition of smoking."
There is absolutely no reason someone shouldn't be able to vape in a bar that allows it or use a hookah in a hookah bar.
