I think the same thing and it pisses me off sometimes that my bro won't quit. I say won't and not can't because I know he can, he just doesn't want to. The social aspect of it is stupid too, he'll just be sitting there at a party not even thinking about cigs and someone will ask him "Wanna smoke?" and I'll see him hesitate for the briefest instant before agreeing. I KNOW he doesn't want to smoke, but he just does because one of his friends wants to.
