The document summarizes several scholarly articles that study the effectiveness of hypnotherapy for smoking cessation. The articles found that hypnotherapy success rates for quitting smoking ranged from 81-90.6% immediately after treatment, and were still effective with rates of 48-87% after longer term follow ups of 6 months to 2 years. Hypnosis was also found to be more effective than other methods like willpower alone, nicotine patches, or drug interventions for helping people stop smoking. The largest study to date concluded that hypnosis was 3 times as effective as nicotine patches and 15 times as effective as willpower alone in treating smoking addiction.
