Believe it or not but that room full of glycerin vapor was probably good for your condition. I'm not being a smartarss either, I'm dead serious. And a room full of cigarette smoke and a room full of vapor from e-cigs are worlds apart in difference. Sorry, that is just the truth. Secondly, if you were so concerned about your health, why did you stay in the room? I mean, if it was the same as if the room was on fire, in your belief, you should have ran out of there.
