I live in the state of WA, and a couple years ago there was an initiative to ban smoking in all public locations, as well as within 25 feet of any entrance. To me, these felt like two completely different issues. I don't care if businesses allow smoking - I can avoid them. Keeping smokers away from entrances, however, was enough to make me vote yes by itself. I was attending a technical college at the time, and it was impossible to enter the building without walking through clouds bad enough to obscure vision. In summary, I don't care if you want to kill yourself, as long as you keep it away from me.
And on topic, those TRUTH ads have gotten bad enough that I'll frequently change the channel or simply turn off the tv if they come on.
