I agree with you and stopped-started smoking on and on for years. I stopped again a year and a half ago. I'm luckily in the phase in which I totally reject the smell of cigarettes (especially packed: rolling tobacco is less harsh); I found that wearing the mask and passing in a cloud of smoke traps that awful smell in my face for much longer and it becomes much more nauseating. One more point for wearing surgical masks in public, I guess.
