If your in a crowded area its probably going to get on them, poison them, or kill them someday. However, Im pretty sure if your more than ten feet away, say on an aisle in Walmart by yourself, it will dissipate before anyone has a chance to get one of those deadly molecules inside their lungs. That would be the difference in vaping versus smoking. Of course dont even go into rock concerts and their smoke machines which bellow plumes of vg into the audience. Not that they give a crap whats in your PV. Mine just happens to be the same thing as the concert with addition of a few mg of flavoring.
Excellent post, trazzman! You said it all!
