Hypnosis is the most effective way of giving up smoking, according to the largest ever scientific comparison of ways of breaking the habit. Results of more than 600 studies of 72,000 people from America and Europe compared various methods of quitting. On average, hypnosis was over three times as effective as nicotine replacement methods and 15 times as effective as trying to quit alone.
