My husband has been cigarette-free for over a year now. He did it with Chantix, which helped -- but what REALLY helped him were the e-cigarettes. They look like a cigarette, and you get nicotine from them. You puff on them and what looks like smoke comes out of them -- it's actually water vapor. Now he's hooked on those e-cigarettes, but at least no smell of smoke anymore and none of the tar & smoke to damage his lungs. He's hooked on the nicotine, and I think he 'smokes' more now -- he ALWAYS has one in his mouth -- but I don't think that's as damaging.
