I also have the dark vape stains...
I am a coffee drinker, but never had the problem to the same extent while smoking.
Does straight nicotine stain teeth? When people talk about "nicotine stains", I'd always assumed they meant *tar* stains, but maybe I'm wrong? Maybe nicotine on its own really does stain tooth enamel?
