Does hypnosis to quit smoking really work? Scientific evidence and an honest take
Practitioners claim 35-45% success at 6 months, but Cochrane stays cautious. Sorting what we know, what we do not, and who it might suit.
The scientific basis on quitting smoking was reviewed on a voluntary basis by Pr. Bertrand Dautzenberg , a tobacco specialist, in order to rule out gross, potentially dangerous errors. It reflects positions commonly shared by health professionals and health agencies, without always corresponding exactly to his thinking or his practice. He is not the author of this text; he has only carried out a vigilance review of it.
"I had one session and never touched a cigarette again." You have probably heard that kind of testimonial. But what does the science say? Sorting fact from fiction, no demonising, no overselling — to help you decide with the facts.
How it works, in theory
Hypnosis aims to put the smoker into an altered state of awareness (deep relaxation, focused attention), during which the practitioner delivers suggestions: "you no longer need this cigarette", "your body is free", "your breath is coming back". The idea: rewire some of the unconscious automatisms linked to smoking.
Hypnosis can help, especially smokers with good suggestibility and real motivation. It does not work by magic — it helps mobilise a decision that has already been made.

The Cochrane caveat
Why the gap between practice and meta-analyses? Several theories:
Who it works well for
| Profile | Likelihood hypnosis helps |
|---|---|
| Highly motivated, moderate dependence | High |
| Sensitive to suggestion (high "hypnotisability") | High |
| Prefers non-pharmacological approaches | High |
| Anxious: looking for a relaxing effect | Moderate |
| Highly dependent physically (Fagerstrom 7+) | Low — better with medication + support |
| Sceptical on principle | Low (placebo effect runs in reverse) |
| Polydrug user | Variable — depends on overall protocol |
What a session looks like
-
Pre-session interview
your smoking story, your motivation, your triggers, previous attempts.
-
Induction
the hypnotist guides you into deep relaxation (10-20 min).
-
Therapeutic suggestions
targeted phrases on tobacco, your body, your regained freedom (15-30 min).
-
Gradual return and debrief: what you felt, what you take away.
-
Plan
number of follow-up sessions, self-hypnosis exercises to practise at home.
A session lasts on average 1 hr to 1 hr 30. Cost varies by practitioner (60 to 150 GBP per session in the UK). No NHS funding for stop smoking hypnotherapy, except in rare hospital settings.

Your questions
-
How do I find a good hypnotherapist to quit smoking?
Look for a registered health professional (doctor, nurse, psychologist) trained in medical hypnotherapy. Check the directories of the BSCAH (British Society of Clinical and Academic Hypnosis) or the Royal Society of Medicine Hypnosis section. On directories, filter by "hypnotherapist" and read profiles carefully. -
How many sessions on average?
3 to 5 sessions in most serious protocols. Be wary of "1 session is enough" promises: it can work for highly suggestible profiles, but it is not the norm. -
Is hypnosis dangerous?
No, no serious harm is documented in the scientific literature for stop smoking work. You stay conscious throughout, can stop at any time, and no one can make you do anything against your will. -
If the first session does nothing for me, should I stop?
Not necessarily. Many people need 2 or 3 sessions to reach a truly effective hypnotic state. If after 3 sessions you feel nothing, it is probably a sign this method is not for you. -
Does hypnosis also work for the hand-to-mouth habit?
That is often where it shines. Many protocols specifically target conditioning (the urge triggered by coffee, the car, drinks). For strong physical dependence, pair it with NRT.
