So are you also banning asthmatics from using their inhaler in public? You're getting secondhand propylene glycol from them too!

I don't smoke or vape, but I really don't see why vaping is so unpopular. Is it just "drugs are bad" again? I again don't get it, as nobody complains about seeing people drinking coffee in public. As far as I can tell, caffeine and nicotine are similar drugs with different delivery mechanisms. Except nobody is worried about high school students getting hooked on caffeine from flavored coffee beverages.
