Same here. I smoke sometimes when I'm out at the bar. In fact, I'll occasionally chain-smoke a whole pack in an hour or so. But I never get nicotine cravings and I never smoke at home or when I'm on my own. It's only when I'm drinking and I'm around other people who are smoking. Actually, I think I only smoke because the best way to socialize and pick up girls at the bars is when they're outside in the quieter smoking section.
