I smoked for 1.5-2 years. And then one morning i just woke up and stoppped. I think most smokers are addicted to the oral fixation, and not the nicotine.
In general, smoking doesn't bother me because if someone wants to trash their body, by all means, it's thier body.

They stink, they make the areas they smoke in stink, and it takes a long time for it to come out.

I'd say this retains to this thread. Ontario is pushing to pass a law of no smoking with kids in your car, and that makes me happier than a pig in , cause i have a daughter and her mother smokes, so I'm really happy about that.
