You seems to be lucky with addiction, but it's so incredibly rare, research into that might be impossible without killing a bunch of people, making them addicted to nicotine. Anecdotally, all my friends who were casually smoking "only at parties" or no more than a sig a day, either stopped, or started smoking for real.
I have super debilitating ADHD, and my lack of tendency to form addictions is just about the only advantage, but I'll take it gladly.
