Hypnosis, acupuncture, the Allen Carr method: do these ways to quit smoking really work?

When trying to quit smoking, many people look for an alternative to nicotine replacements and medication. Hypnosis, acupuncture, the Allen Carr method: these so-called "alternative" approaches often promise a gentle quit, with no patches and no prescription. But how much are they really worth? This article puts these methods under the microscope of scientific evidence, drawing on benchmark reviews such as those from the Cochrane collaboration, and on the positions of the World Health Organization (WHO) and France's Haute Autorité de santé (HAS). The goal is not to sell a miracle cure, but to say honestly, method by method, what we know and, above all, what we still do not.

Why these methods are so appealing

Their appeal is easy to understand. They present themselves as drug-free and substitute-free, which reassures people who are wary of treatments. They highlight a "gentle" quit, sometimes in a single session, by working on motivation, beliefs or the psychological side of addiction rather than on the physical craving. The promise of a quick, natural transformation is powerful, especially after several failed attempts with other methods. The problem is not the idea itself, but the frequent gap between the marketing claims and the actual level of evidence. Looking at the available data makes it possible to choose wisely, without giving up what keeps you motivated.

Hypnosis: insufficient evidence

Hypnotherapy aims to change how you perceive cigarettes and to strengthen the will to quit through suggestions made in a state of deep relaxation. On paper, the idea is attractive. But the Cochrane reviews that have pooled the available trials conclude that the evidence is insufficient to claim that hypnosis helps people quit more than other approaches, or more than no treatment at all. The studies are often few, small and methodologically limited, which rules out any firm conclusion. This does not mean hypnosis is useless for everyone: for some people it can support motivation and accompany a commitment that has already been made. But given current knowledge, nothing allows it to be presented as a method whose effectiveness has been proven.

Acupuncture: no solid evidence

Acupuncture, sometimes offered as needle insertion or "auricular therapy" (stimulating points on the ear), is supposed to reduce the urge to smoke. Here too, the Cochrane reviews are cautious: there is no solid, consistent evidence of a real effect of acupuncture on long-term smoking cessation. When an effect appears in some studies, it is usually small, short-lived and hard to distinguish from the placebo effect or the simple attention paid to the patient. In other words, any observed benefit often owes more to support and motivation than to the technique itself. Acupuncture may feel like a supportive ritual, but it cannot be recommended as an effective treatment for tobacco dependence on the basis of current data.

The Allen Carr method: limited but encouraging evidence

The Allen Carr (Easyway) method, popularised first through the book and then through seminars, rests on a psychological approach: dismantling the beliefs that make cigarettes seem "desirable", so the urge to smoke fades instead of having to be fought. Its case is interesting, because the evidence, still limited, is rather encouraging. A randomised controlled trial (of the type by Keogan and colleagues, published in 2019) compared an Easyway seminar with standard stop-smoking services and suggests effectiveness at least comparable to those benchmark services. That is a notable result, but it calls for measured optimism: we are still talking about a small number of studies, and further independent work would be needed to confirm these findings over the long term. The Allen Carr method thus stands out as the most promising in this overview, without yet being a validated standard on a par with the reference treatments.

Homeopathy, herbs, nicotine-free cigarettes: the lack of evidence

Other methods are still circulating, often presented as natural. Homeopathy has no evidence of effectiveness for quitting smoking. Herbs and supplements (especially those meant to make tobacco "disgusting") lack reliable data showing a real benefit. As for nicotine-free e-cigarettes or dummy cigarettes designed solely to reproduce the hand-to-mouth gesture, they may help manage the behavioural habit but do not treat physical nicotine dependence and have not been shown to increase the chances of a lasting quit. For all these approaches the conclusion is the same: in the absence of convincing evidence, they are closer to personal support than to a treatment of established effectiveness.

The takeaway: motivation, placebo and proven methods

This overview calls for nuance. The placebo effect and motivation play a real role in any attempt to quit, and a method that strengthens personal commitment is never entirely useless. But that must not lead anyone to neglect the approaches whose effectiveness is proven. According to the WHO, the HAS and the Cochrane reviews, nicotine replacement therapy, certain medications (such as varenicline or cytisine), the nicotine e-cigarette and behavioural support remain the best-validated pillars. The ideal is not to set these worlds against each other: a person can perfectly well rely on a motivational method while also using an effective treatment. Here, in summary, is the level of evidence by method:

• Hypnosis / hypnotherapy: insufficient evidence (Cochrane); may support motivation for some people.
• Acupuncture: no solid, consistent evidence of an effect on quitting smoking (Cochrane).
• Allen Carr method (Easyway): limited but encouraging evidence; at least comparable to standard support services.
• Homeopathy, herbs, nicotine-free cigarettes: lack of evidence of effectiveness for quitting.
• Replacements, medication, nicotine e-cigarette, support: well-established effectiveness, to be prioritised.
