I quit my pipe before oral surgery, nothing too gruesome but needful to prepare for speedy healing "at my age." I'm now still holding off afterwards, letting the gum grow back. The surgeon called this "developing the architecture" of the gums. I wondered how I'd do without any nicotine. As I have always suspected, that's not the attraction of pipe smoking for me. I don't get giddy, moody (any more than usual), or craving the weed. That's just not what draws me. I look forward to the ritual and rumination that goes with it, but the nicotine isn't the joy. When I get the occasional buzz, that's nice, but I never pack a pipe with that in mind. People are widely different in this; for some it's the whole point, and then there's a wide range of responses, all the way to people who have little or no reaction to nicotine at all. I have a little, but so far, nothing habit forming. Just interesting to run the experiment, since I had to do it for dental/medical reasons anyway.
