The success of smoking cessation interventions appears to be most closely related to the amount of positive reinforcement that the smoker receives for not smoking (unpublished data). The goal of the clinic is to reinforce not smoking over the longest period of time. The program outlined focuses on helping the smoker who wants to stop smoking, it demands a minimal amount of time from the physician and it is self-supporting. If these guidelines are followed, the physician should find that helping the smokers who want help to stop smoking is a productive and rewarding experience.
