How can you help a person who wants to stop smoking?

Stop Smoking Clinic: Find a stop smoking clinic in your area. Many hospitals have them. They will help you stop in several different ways. It is very difficult to go it alone. You need help.

Quit contract.: Smokers are very good at fooling themselves into smoking again. With a quit contract, the smoker has to answer to you, or to a group of friends, or to a group of people who are also trying to quit. Answering to others for one's indiscretions is difficult, and can help the quitter in his/her attempt.
