WSJ had a very interesting piece on smoking and why people continue to smoke. Addiction is not a major reason anymore (if it ever was), but psychological reasons abound.

One quibble: for some reason cigars and pipes appear to be included. but should they? Neither is a cigarette, nor enjoyed like a cigarette. Nor is cigarette tobacco the same type, kind of tobacco we find in cigarettes, but that topic we’ll save for another day.
