I found this interesting article today concerning research done in the USA suggesting that most smokers want to quit.

One interesting point concerning previous smokers who were successful in quitting smoking suggests that there was no magic bullet with regard to strategies for stopping but rather just a basic decision to quit. This seems to be the case in the vast majority of people who have given up smoking: making the decision 100% to quit and then acting on that decision.
Our job as hypnotherapists in a lot of ways is to help people come to that decision on all levels of their being and help them access the skills necessary to act on that decision.

You can take a look at the article here:
