A majority of places just outright ban smoking in public places now.  Even backward Indiana does this.  Even if you go outside to smoke the smokers still stink of cig smoke.  Their clothes, their hair, their cars-all stink.  Not to mention you are risking your life which is also really stupid.  Cancer is a horrible way to die.  Why not at least TRY to quit?  And it certainly should not be an excuse to get extra breaks though I've never heard of that.
