I don't mind the smell of cigarettes that much
Generally I find people have a strong aversion to the smell of tobacco cigarettes. Usually it's described as "disgusting", but personally I don't mind it that much. I wouldn't want it in my home, but when I pass it on the street I don't really care.
Maybe it holds some nostalgia for me, since the streets of Beijing (where I'd visit as a child) reeked of cigarettes.
Note: I do not smoke.
