Rather than trying to stop your smoking habit in one step, the program systematically adds elements to your habit until it doesn't recognize itself. No fight, no fuss, just deadening disinterest. Next, you learn how to confuse your habit type cigarettes and how to isolate your addiction cigarettes from other reinforcers. As your habit weakens, you work in substitutes and learn how to forget to smoke. Eventually smoking becomes too much of a bother.
Persistence is the only requirement for the program to work.
If you stay with the program, even if your progress is slow, you will become a non-smoker. Dismantling a habit which took years to develop, however, takes time. Fortunately, you won't have to wait that long. With serious effort, you will start noticing the changes in about three weeks. Moreover, you can keep smoking.
