> I know a lot of people who smoke just to socialize and occasionally; they are not addicted and seem to have no problem with not smoking at all...

I'm one of these people. I enjoy smoking cigars every once and awhile, and will enjoy a cigarette or two with no danger of addiction if I happen to be drunk and at a party with smokers. With that being said, I could easily see how an occasional smoker could turn into a regular smoker over time if tobacco was readily available and they were hanging around with other smokers regularly.
