Thus, tobacco companies support a ban on smoking in public areas because they sell more cigarettes.

OK that made me laugh. Dang near blew coffee out my nose. Good one! (Wait...you're not joking?)

Have you ever seen a smoker get off an airplane? They go right to the exit and chain smoke several cigarettes until they get their nicotine levels back up. I wouldn’t be surprised if smokers smoke less when they can regulate their intake evenly throughout the day, rather than chain smoking during coffee breaks, quick trips outside to the bank or post office, or between flights.
