Thank you for this. I smoke pipe tobacco and cigars. 15 years ago I smoked only occasionally and just stopped out of the blue. An alter was the smoker, and I stopped when he went dormant for a while. He came back a year ago and started right up. He and I integrated, and now I smoke daily. Another alter is also a smoker, and the rest tolerate it because it feels good. Don’t want to see myself still smoking years from now, and your comments are the most helpful I’ve heard on the subject.
As an aside, my cousin quit smoking by vaping. She started vaping fruity flavors to get herself away from the cigarette taste and smell, which she eventually started to dislike as time went on. Then she dialed down the nicotine level gradually until she was using no nic at all, then she put away the vape for good.
