That's tough, Sean. I have a few friends that only smoke in social situations. I can't, for the life of me, understand that. But anyways...when you're out at a bar, grab a stirring straw and hold on to that and chew on it if you need to. That may occupy the areas of your consciousness that tell you you should be holding onto something and/or have something in your mouth.

...or you could advocate fascist smoking bans, like Lincoln has.
