Hypnosis is sometimes used as a complementary therapy to help people quit smoking, but its effectiveness is still a matter of debate. Some studies have suggested that hypnosis can be helpful in aiding smoking cessation, while others have not found a significant benefit compared to other forms of treatment. It is important to note that hypnosis is not a standalone treatment for smoking cessation and is usually used in combination with other therapies, such as counseling or medication. Additionally, hypnosis may not be effective for everyone, and success rates may vary depending on individual factors such as motivation and willingness to quit.
