Same can be said of the drugs they campaign so hard against too. There's plenty of problems with stuff like ecstasy / meth and the like, and I'm sure they cause problems that affect non-users people indirectly, but cigarettes are insidious in that you're going to breath in that crap whether you like it or not as soon as you go anywhere where smoking is prevalent.
But I'm sure the money they getting over and under the table makes it all okay! /s
