I do know someone like this. Me. I'm not sure what you mean by "using psychology" to quit. I will tell you this, and I am an absolute authority on it. There is only one way to quit an addiction that is proven, and it only has a 2% success rate. That way is the 12 steps of AA, developed in the 1930's by Bill W. and Dr. Bob. I'm a proponent of that program, and proof it works, as I am now more than 32 years clean and sober from alcohol and drugs. Yet, interestingly, I did not give up smoking until last year. This is after over 50 years of smoking. I started at age 11, a year before I began drinking. Had I been wise enough, I'd have quit the smoking when I quit the other addictions. But I liked the smoking. Why? Nicotine is by far the most addictive substance on Earth, far more so than any other. I watched my Mom slowly waste away from COPD and die, still smoking till the last, while never even pausing my own smoking for twenty more years! WTF? Even though I knew what was coming. That is the power of it. So here I sit at my desk at home, forcibly retired, typing this with a cannula in my nose 24 hours a day. The 12 steps were not enough for me by themselves. For nicotine, it took fear too. When I found myself unable to breathe, the fear was finally strong enough, and (having already been trained in the 12 steps) I quit, right there on the spot, that day, and it was easy. Too late, but still.
The insanity of it all is a true phenomenon to witness, but we see it every day. Now my youngest son and his fiancé come to visit, and I have to tell them to go outside to smoke. They still don't get it. I hope I can convince them while I'm still here.
The answer to your question? I think that if you had a program where people could be hooked up to a device that would stop them from breathing for long enough for them to feel that fear, that might work. That's all I got. I don't think anything else will.
