Can hypnosis help people quit smoking?

01

What hypnosis adds depends on what the other group receives

Cochrane included 14 trials involving 1,926 participants, with a search ending on 18 July 2018. Outcomes were measured at least six months after treatment began; that does not mean every trial required six months of uninterrupted abstinence. The programmes and comparison groups varied too much for one overall effect estimate.

Six trials matched therapist contact time with behavioural support. Their combined result did not demonstrate a significant advantage for hypnosis, with low certainty. Five trials testing hypnosis as an addition to other treatment did report a favourable pooled result, but high risk of bias and unexplained differences between trials limit confidence. That signal should neither be erased nor turned into an established add-on benefit.

The 2024 paper is informative—but not a new independent sample

A German trial published in 2024 compared six weekly group sessions of hypnotherapy with six sessions of cognitive behavioural therapy (CBT), matched for contact time. It randomized 360 adults in 2010–2012; one participant requested deletion, leaving 359 in the analysis. Twelve months after the course, the trial's Russell-standard continuous-abstinence rates were 15.0% for hypnosis and 15.6% for CBT. This research definition allows a limited lapse; it is not a statement that every participant smoked absolutely nothing throughout the year.

The primary comparison was not statistically significant. The study tested for superiority, so that finding is not formal proof of equivalence or of a universal ‘just as effective’ service. Seven-day abstinence and additional adjusted analyses were separate questions, not interchangeable with the primary outcome. The paper also states that these then-unpublished results had already been included in the 2019 Cochrane review. Do not add this sample to the review as if it were new participants, or transfer a six-week group programme's findings to a one-session or audio-only offer.

A positive-study percentage is not your chance of quitting

A 2025 systematic review reaches a more favourable conclusion. Its public abstract describes 63 included papers, with 66.7% of a subset of 33 studies reporting a positive impact. That number counts studies reporting a result—not people who quit—and is not a pooled quit rate. Its eligibility includes hypnosis alone or within multicomponent interventions, and objective or subjective outcome measures.

A study may report a change in cigarette consumption, an abstinence measure or another component's contribution. The abstract calls for better biological confirmation, treatment-fidelity assessment and adverse-event reporting. It does not supply the detail needed to make every study's comparator and follow-up identical. ‘A newer review is positive’ cannot, by itself, resolve the narrower question of lasting abstinence compared with equally intensive support.

Keep safety, qualifications and results separate

The older trials often failed to report whether adverse events were collected. The German trial did monitor safety-critical events, including changes in mood; their occurrence alone does not establish that hypnosis caused them. Neither limited reporting nor absence of a significant difference proves safety for every person. Personal suitability belongs in a qualified clinical discussion, not a suggestibility test or a recording supplied here.

In the UK, NHS information distinguishes accredited professional registration from statutory regulation; a register is not evidence of quitting effectiveness. NHS Better Health links to local stop-smoking help. Elsewhere use your own qualified local service. A useful question is: ‘What exact programme was studied, against what support, for how long, and how were unwanted events handled?’ This page does not certify a provider, choose treatment or ask you to replace current care.

What to keep in mind

• Match the programme, comparator and abstinence definition.
• New publication does not necessarily mean new participants.
• Qualifications and reported outcomes answer different questions.
