Our smoking cessation classes use the Cooper-Clayton Method, a safe and effective way to help people stay smoke-free for the rest of their lives. The Cooper-Clayton Method is a comprehensive behavioral smoking cessation program that was started more than 20 years ago by Thomas Cooper, DDS, a dentist and former heavy smoker, and Richard Clayton, PhD, an expert on drug addiction. This highly successful program is science based and uses proven methods, including education, skills training and social support. There are 13 weekly one-hour sessions followed by relapse prevention. Participants use nicotine replacement products such as the nicotine patch, nicotine gum or nicotine lozenge.
