I don't have this in general, but when you were talking about someone who is quitting smoking I just realised that I have a distinct visual impression of the smell when a smoker really needs to have a smoke. It's kind of yellowish and it falls off them and gathers at their feet like a kind of fog.

I'm a super taster for a few things and I suspect that whatever odor that is, I can detect it better than most. Anyway, thanks for your description!
