Results of a study were presented at the annual meeting of the American College of Chest Physicians in October 2007 that showed that half of hospitalized smokers had success of smoking cessation with hypnosis compared with other approaches tested in a comparison study. The study showed that hypnosis was twice as effective as the next best smoking cessation approach, including pharmacologic treatments The study compared four smoking cessation programs in hospitalised patients who were motivated to quit. Compared were hypnosis, nicotine replacement therapy (NRT), hypnotherapy plus NRT, or abrupt cessation without other treatment (cold turkey). All of the patients expressed a desire to stop smoking which as we know is a key component to success.
Interestingly, it was found that men were more likely to choose a "quick fix," going cold turkey or choosing a NRT patch while women were more likely to choose hypnotherapy. All patients received counselling in this study. Patients receiving hypnosis had an initial session while in the hospital and a second session a week after discharge. Patients receiving NRT began therapy during hospitalization and continued with NRT during the month after discharge.
After 6 months, 50% of patients who underwent hypnosis remained smoking-free as were those who received hypnotherapy plus NRT. One quarter of patients who went cold turkey remained successful, while 15.78% of those who received NRT alone continued to not smoke. It was found that, adding NRT did not help the success of hypnotherapy. Patients who had been hospitalised with a cardiac diagnosis were more likely to be successful at quitting than those with a pulmonary diagnosis, with success rates of 45.5% and 15.63%, respectively.
