C Unclear or conflicting scientific evidence
- Acupressure : The practice of applying finger pressure to specific acupoints throughout the body has been used in China since 2000 BC, prior to the use of acupuncture. Acupressure techniques are widely practiced internationally for relaxation, wellness promotion, and the treatment of various health conditions. Shiatsu means finger (Shi) pressure (Atsu) in Japanese. Shiatsu can incorporate palm pressure, stretching, massaging and other manual techniques. Early study indicates that auricular acupressure (pressure to points on the ear) may help with smoking cessation. Also, preliminary evidence suggests that acupressure may be a helpful adjunct therapy to assist with the prevention of relapse, withdrawal, or dependence.
- Astragalus : Astragalus (Astragalus membranaceus) is commonly used in traditional Chinese medicine (TCM). Limited available study has reported positive benefits in smoking cessation. However, more human studies are needed.
- Avoid if allergic to astragalus, peas, or any related plants or with a history of Quillaja bark-induced asthma. Avoid with aspirin or aspirin products or herbs or supplements with similar effects. Avoid with inflammation (swelling) or fever, stroke, transplants, or autoimmune diseases (like HIV/AIDS). Stop use two weeks before surgery/dental/diagnostic procedures with a risk of bleeding and avoid use immediately after these procedures. Use cautiously with bleeding disorders, diabetes, high blood pressure, lipid disorders, or kidney disorders. Use cautiously with blood-thinners, blood sugar drugs, or diuretics or herbs and supplements with similar effects. Avoid if pregnant or breastfeeding.
- Black pepper : Sensory cues associated with cigarette smoking can suppress certain smoking withdrawal symptoms, including the craving for cigarettes. Inhalation of black pepper essential oil may reduce cravings and physical symptoms associated with cigarette smoking cessation.
- Avoid if allergic or hypersensitive to black pepper (Piper nigrum), its constituents, or members of the Piperaceae family. Use cautiously if taking anti-asthmatic drugs, cholinergic agonists, cyclosporine A or digoxin, cytochrome P450 metabolized agents, oral herbs or drugs, phenytoin, propranolol, rifamipicin (rifampin), or theophylline. Use cautiously with gastrointestinal disorders. Avoid if pregnant or breastfeeding.
- Eucalyptus oil : Nicobrevin is a proprietary product marketed as an aid for smoking cessation that contains quinine, menthyl valerate, camphor, and eucalyptus oil. Despite use of this product, there is currently a lack of evidence suggesting benefit for smoking cessation.
- Avoid if allergic to eucalyptus oil or with a history of seizure, diabetes, asthma, heart disease, abnormal heart rhythms, intestinal disorders, liver disease, kidney disease, or lung disease. Use caution if driving or operating machinery. Avoid with a history of acute intermittent porphyria. Avoid if pregnant or breastfeeding. A strain of bacteria found on eucalyptus may cause infection. Toxicity has been reported with oral and inhaled use.
- Guided imagery : In contemporary times, the term "guided imagery" may be used to refer to a number of techniques, including metaphor, story telling, fantasy, game playing, dream interpretation, drawing, visualization, active imagination, or direct suggestion using imagery. Therapeutic guided imagery may be used to help patients relax and focus on images associated with personal issues they are confronting. Based on early study, guided imagery in addition to education and counseling sessions may be helpful for long-term smoking cessation and abstinence in adult smokers. Further study is needed to confirm these results.
- Guided imagery is usually intended to supplement medical care, not to replace it, and guided imagery should not be relied on as the sole therapy for a medical problem. Contact a qualified healthcare provider if mental or physical health is unstable or fragile. Never use guided imagery techniques while driving or doing any other activity that requires strict attention. Use cautiously with physical symptoms that can be brought about by stress, anxiety, or emotional upset because imagery may trigger these symptoms. If feeling unusually anxious while practicing guided imagery, or with a history of trauma or abuse, speak with a qualified healthcare provider before practicing guided imagery.
- Meditation : Available evidence does not indicate whether meditation can help with smoking cessation. More studies are needed.
- Use cautiously with underlying mental illnesses. People with psychiatric disorders should consult with their primary mental healthcare professional(s) before starting a program of meditation, and should explore how meditation may or may not fit in with their current treatment plan. Avoid with risk of seizures. The practice of meditation should not delay the time to diagnosis or treatment with more proven techniques or therapies, and should not be used as the sole approach to illnesses.
- Melatonin : Melatonin is a hormone produced in the brain and is involved in the sleep wake cycle during light and darkness. Levels of melatonin in the blood are highest prior to bedtime. A small amount of research has examined the use of melatonin to reduce symptoms associated with smoking cessation, such as anxiousness, restlessness, irritability, and cigarette craving. Although preliminary results are promising, due to weaknesses in the design and reporting of this research, further study is necessary before a firm conclusion can be reached.
- Melatonin is not to be used for extended periods of time. Melatonin can cause drug interactions, and healthcare professionals recommend not using in pregnancy or breastfeeding.
- Prayer : Traditional forms of prayer in the treatment of addiction and smoking cessation are widely used. However, initial research does not report effects of prayer on smoking dependency.
- Prayer is not recommended as the sole treatment approach for potentially serious medical conditions and should not delay the time it takes to consult with a healthcare professional or receive established therapies.
- Psychotherapy : Several studies suggest that group therapy may be more effective than self-help for smoking cessation. However, there is not enough evidence to show that group therapy is as effective or cost-effective as intensive individual counseling. More research is needed to determine effectiveness.
- Psychotherapy is not always sufficient to resolve mental or emotional conditions. Psychiatric medication is sometimes needed. The reluctance to seek and use appropriate medication may contribute to worsening of symptoms or increased risk for poor outcomes. In order to be successful, psychotherapy requires considerable personal motivation and investment in the process. This includes consistent attendance and attention to treatment recommendations provided by the practitioner. Not all therapists are sufficiently qualified to work with all problems. The client or patient should seek referrals from trusted sources and should also inquire about the practitioner's training and background before committing to work with a particular therapist. Some forms of psychotherapy evoke strong emotional feelings and expression. This can be disturbing for people with serious mental illness or some medical conditions. Psychotherapy may help with post-partum depression, but is not a substitute for medication, which may be needed in severe cases.
- Relaxation therapy : Early research reports that relaxation with imagery may reduce relapse rates in people who successfully completed smoking cessation programs. Better study is needed in this area before a firm conclusion can be reached.
- Avoid with psychiatric disorders like schizophrenia/psychosis. Jacobson relaxation (flexing specific muscles, holding that position, then relaxing the muscles) should be used cautiously with illnesses like heart disease, high blood pressure, or musculoskeletal injury. Relaxation therapy is not recommended as the sole treatment approach for potentially serious medical conditions, and should not delay the time to diagnosis or treatment with more proven techniques.
D Fair negative scientific evidence
- Acupuncture : Numerous studies of acupuncture for smoking cessation have been conducted, and the quality of studies has varied widely. There may, however, be some benefit in reducing side effects of withdrawal such as irritation, cigarette craving, and headache. Additional research is needed.
- Needles must be sterile in order to avoid disease transmission. Avoid with valvular heart disease, infections, bleeding disorders, medical conditions of unknown origin, or neurological disorders. Avoid if taking drugs that increase the risk of bleeding (e.g. anticoagulants). Avoid on areas that have received radiation therapy and during pregnancy. Use cautiously with pulmonary disease (e.g. asthma or emphysema). Use cautiously in elderly or medically compromised patients, diabetics, or with history of seizures. Avoid electroacupuncture with arrhythmia (irregular heartbeat) or in patients with pacemakers because therapy may interfere with the device.
- Hypnotherapy : Hypnotherapy involves suggestion by therapists during periods of deep relaxation. Although used for smoking cessation with some positive results, there is currently a lack of scientific evidence for hypnotherapy as a valid treatment for this indication.
- Use cautiously with mental illnesses like psychosis/schizophrenia, manic depression, multiple personality disorder or dissociative disorders. Use cautiously with seizure disorders.
