As a lifelong non-smoker whose mother - a smoker - died of lung cancer, I don't object to other people smoking at all. Though I will probably remove myself from smoking in a closed space because a) I have asthma and b) cigarette smoke can provoke headaches (I avoid anything that can provoke headaches as my headaches can last for days.)

As for people smoking smelling of tobacco, If I can put up with the smell of bad perfume on other women (one of the most common, least pleasant and most pervasive smells I can think of), I can certainly put up with the smell of tobacco smoke on other people's clothes. In fact I quite like the smell of stale tobacco, and of old beer, and woodsmoke, even horse dung.
