Are from all the smokers who don't want to be bothered by people asking questions?
I asked a simple question if there are any studies showing if the vapor could be harmful to health because I am allergic to cigarette smoke - honestly want to know if I am going to have reactions to someone using this product!
Thanks for proving my inquiry is legit, because fear shows where truth needs to be exemplified.
Also explains why big tobacco is interested in these.
The more downvotes the more of a stink you will make (pun intended).
