Hypnosis is often promoted as a way to stop smoking by changing the thoughts and habits associated with cigarettes. Some people turn to it because they want to quit without medication, while others hope it will help them overcome cravings or avoid relapsing after quitting. But does hypnosis really work? What does the scientific evidence say?
What is hypnosis?
Hypnosis, also called hypnotherapy, involves guiding a person into a state of deep relaxation and focused attention. During a session, the therapist may use suggestions intended to strengthen the desire to stop smoking, change the way cigarettes are perceived or help the person respond differently to situations that trigger the urge to smoke. Contrary to a common misconception, hypnosis does not involve losing control or being forced to do something against your will.
Is hypnosis effective to quit smoking?
Scientific research has not yet established that hypnosis is an effective way to quit smoking. A Cochrane systematic review (an authoritative source), published in 2019, examined 14 studies involving nearly 2,000 people. It found no reliable evidence that hypnosis helped more people quit than other forms of support, such as counselling. The quality of the available studies was generally low, making it difficult to draw firm conclusions.
The World Health Organization’s 2024 guidelines also found insufficient evidence to recommend hypnosis for smoking cessation.
Should you use hypnosis to quit smoking?
Some people may find the relaxation and focused attention helpful when dealing with stress or the habitual aspects of smoking. However, hypnosis should not replace treatments that have demonstrated effectiveness, such as nicotine replacement therapy, prescription medication such as varenicline and cytisine, and behavioural counselling. If you decide to try it, consider it a complement to established treatments rather than a substitute for them.
