Oh, I actually thought I deleted this comment since I realized I didn't really know what I was talking about. But since it's here, and you took the time to read it; The question that went through my mind is "okay, I know that there's more to vaping/smoking than just nicotine, but what about chewing tabbaco? Isn't that nicotine that harms you without the additives from smoking/vaping?
I started with that article, but got lazy and didn't want to look into it further. Sorry for the confusion.
