Fair, ignoring the reality though. Way too many people have no access to clean water, or air, or food, or housing, or safety.

Bitching about the occasional second hand smoke whiff when moving about outside - while there are an insane amount of cars emitting exhaust fumes, rubber particles; factories churning out pollution, and so forth doing far worse to your health every day - is a little like being mad about too much sodium in your industrial runoff tainted drinking water.

The point being, there are much more imminent and important battles to fight for clean air (and water, and all the other things any human should have) than to impede on the unhealthy habit of your fellow peasants in my opinion.
