People rarely lived to 100 before smoking and pollution either. Neither is good for you but cell decay is a fact of life.
That was more due to the fact of diet. However longevity shot way up - almost by double - with industrialization because people started having affordable access to all manner of good foods that were otherwise unavailable. Anyone who lives in a city should be a hell of a lot more concerned about cars and factories then smoking. That's just an easy scapegoat the government deflects with. Look how hard it is to get cleaner cars on the road and cleaner factories.
As a friend of mine once said, sit in a closed garage and smoke a few packs of smokes over an hour or two and you might feel nauseous. Do it with a running car and you won't be walking out of that garage. It's like when I see people jogging or biking in the heart of the city through all that traffic, it's pretty amusing when they rail against cigarette smoke.
