Hypnosis and Smoking: What is the Evidence?

Habits are hard to break. Most people need support to change a long-standing habit, particularly one as addictive as smoking. Hypnosis has emerged as a promising tool for smoking cessation. But what does the research say?

What is Hypnosis?

Hypnosis is a therapeutic technique that involves inducing a deeply relaxed state of consciousness, during which the mind becomes more receptive to suggestion. In the context of smoking cessation, hypnosis aims to reprogram the subconscious mind to break the patterns of smoking behaviour and to reinforce the desire to quit.

What is the evidence?

Studies have investigated the efficacy of hypnosis as a smoking cessation aid. Here's an overview:

1. Clinical Trials:

Clinical trials have demonstrated the positive impact of hypnosis on smoking cessation rates. For example, a randomized controlled trial published in the Journal of the American Medical Association (JAMA) found that smokers who received hypnosis therapy were more likely to be abstinent at six months compared to those who did not.

2. Meta-Analyses:

Meta-analyses combine data from many individual studies. A meta-analysis published in the International Journal of Clinical and Experimental Hypnosis concluded that hypnosis was associated with a significant increase in long-term smoking abstinence rates.

3. Brain Imaging Studies:

Research using functional magnetic resonance imaging (fMRI) has shown alterations in brain activity patterns during hypnosis sessions, particularly in regions associated with addiction and craving regulation

Summing up:

Hypnosis is not a cure-all. There must be a willingness to quit and to take action. That said, the evidence shows that clinical hypnosis is effective in helping smokers to quit the habit.
