Quitting Smoking: Hypnosis One program to help people stop smoking cigarettes uses the method of posthypnotic suggestion to remind subjects to avoid smoking. A random sample of 18 subjects agreed to test the program. All subjects counted the number of cigarettes they usually smoke a day; then they counted the number of cigarettes smoked the day after hypnosis. (Note: It usually takes several weeks for a subject to stop smoking completely, and the method does not work for everyone.) The results follow.
