The American Cancer Societies official position is that no controlled studies have produced conclusive evidence proving that hypnotherapy can help people quit smoking. They go on to say that despite the lack of clinical evidence, there does appear to be substantial anecdotal evidence that suggests it can be an effective cessation method for some people.
Sports psychologists may also pursue voluntary certification. This does not confer the legal right to practice, but does demonstrate expertise in a specialty area. Sports psychology professionals at both the master's and doctoral levels are eligible to become Certified Consultants (CC-AASP) through the Association for Applied Sport Psychology (http://www.appliedsportpsych.org/certified-consultants/become-a-certified-consultant).
Although there are different techniques, clinical hypnotherapy is generally performed in a calm, therapeutic environment. The therapist will guide you into a relaxed, focused state and ask you to think about experiences and situations in positive ways that can help you change the way you think and behave. Unlike some dramatic portrayals of hypnosis in movies, books, or on stage, you will not be unconscious, asleep, or in any way out of control of yourself. You will hear the therapist’s suggestions, but it is up to you to decide whether or not to act on them.
