Hypnotherapy shows a positive impact on smoking cessation, with 66.7% of studies reporting success. More research is needed to confirm efficacy using biological measures and assess side effects.
Area of Science:
- Behavioral Science
- Psychology
- Public Health
Background:
- Smoking cessation remains a significant public health challenge.
- Hypnotherapy is an alternative or complementary approach explored for smoking cessation.
- Existing evidence requires comprehensive evaluation to determine hypnotherapy's effectiveness.
Purpose of the Study:
- To systematically review and evaluate the evidence on hypnotherapy for smoking cessation.
- To assess the impact and efficacy of hypnosis interventions in adult smokers.
- To identify factors associated with positive outcomes in hypnotherapy for smoking cessation.
Main Methods:
- Systematic review of 745 nonduplicate publications, including 63 analyzed papers.
- Inclusion criteria: adult participants, measurable smoking cessation data, hypnosis intervention, and ≥10 participants.
- Analysis of 33 studies reporting on the impact of hypnosis for smoking cessation.
Main Results:
- 66.7% of analyzed studies reported a positive impact of hypnotherapy on smoking cessation.
- Positive outcomes were associated with longer treatment duration and more sessions.
- Studies with positive impact more frequently used both self-report and objective cessation measures.
Conclusions:
- Hypnotherapy demonstrates a positive efficacy for smoking cessation.
- Further research is recommended, focusing on biologically confirmed abstinence and reduced cigarette consumption.
- Future studies should assess treatment fidelity, hypnotizability, race/ethnicity, and adverse events.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
