Overview
Tobacco use is the leading cause of preventable disease, disability, and death in the United States. Each year, nearly half a million Americans die prematurely of smoking or exposure to secondhand smoke and 16 million live with a serious illness caused by smoking. Smoking can cause repairable damage to various organs including the heart, lungs, kidneys, stomach and intestines. Smoking is associated with the causation of various cancers in the humans. Quitting smoking cuts cardiovascular risks, reduces risk for stroke to about half that of a nonsmoker’s, reduces risks for cancers of the mouth, throat, esophagus, and bladder by half within 5 years and ten years after quitting smoking, the risk for lung cancer drops by half. Smoking cessation can be achieved by some general, non-pharmacological and pharmacological strategies.
Smoking and Health
The impact of smoking on the health can be summarized as follows:[1][2][3]
Effect of Smoking Cessation on various Risks
- Quitting smoking cuts cardiovascular risks. Just 1 year after quitting smoking, your risk for a heart attack drops sharply.
- Within 2 to 5 years after quitting smoking, your risk for stroke may reduce to about that of a nonsmoker’s.
- If you quit smoking, your risks for cancers of the mouth, throat, esophagus, and bladder drop by half within 5 years.
- Ten years after you quit smoking, your risk for lung cancer drops by half.
Smoking cessation
General Principles
The 5As are an evidence-based framework for structuring smoking cessation in health care settings. The 5As include: Ask, Assess, Advise, Assist and Arrange follow-up.

Pharmacological
First-line pharmacotherapy includes the multiple forms of nicotine replacement therapy (patch, nasal spray, losenge, gum, inhaler), sustained- release bupropion hydrochloride, and varenicline. Second line therapy includes clonidine and nortriptyline and have been found to be efficacious.[4]
The following is a description of the various treatment modalities available:[5]
- Sustained release bupropion hydrochloride:
- Nicotine gum:
- Dose: 1–24 cigarettes/day: 2mg gum (up to 24 pieces/day). ≥ 25 cigarettes/day: 4 mg gum (up to 24 pieces/day).
- Duration: Up to 12 weeks
- Adverse effects: Mouth soreness and dyspepsia
- Nicotine inhaler:
- Dose: 6–16 cartridges/day
- Duration: Up to 6 months
- Adverse effects: Local irritation of mouth and throat
- Nicotine lozenges:
- Nicotine nasal spray:
- Dose: 8–40 doses/day
- Duration: 3–6 months
- Adverse effects: Nasal irritation
- Varenicline:
- Dose: 0.5 mg/day for 3 days followed by 0.5 mg twice/day for 4 days. Then, 1 mg twice/day
- Duration: 3–6 months
- Adverse effects: Nausea, trouble sleeping, vivid/strange dreams and depressed mood
Modalities
Techniques which can increase smokers' chances of successfully quitting are:
- Quitting "cold turkey": abrupt cessation of all nicotine use as opposed to tapering or gradual stepped-down nicotine weaning. It is the quitting method used by 80[6] to 90%[7] of all long-term successful quitters.
- Smoking-cessation support and counseling is often offered over the internet, over the phone quitlines (e.g. 1-800-QUIT-NOW), or in person. One effective way to assist smokers who want to quit is through a telephone quitline which is easily available to all. Professionally run quitlines may help less dependent smokers, but those people who are more heavily dependent on nicotine should seek local smoking cessation services, where they exist, or assistance from a knowledgeable health professional, where they do not. Some evidence suggests that better results are achieved when counseling support and medication are used simultaneously. Quitting with a group of other people who want to quit is also a proven method of getting support, available through many organizations.
- Nicotine replacement therapy, NRT: pharmacological aids that are clinically proven to help with withdrawal symptoms, cravings, and urges (for example, transdermal nicotine patches, gum, lozenges, sprays, and inhalers)
- The antidepressant bupropion, marketed under the brand name Zyban®, helps with withdrawal symptoms, cravings, and urges.
Bupropion is contraindicated in epilepsy, seizure disorder; anorexia/bulimia (eating disorders), patients use of psychosis drugs (MAO inhibitors) within 14 days, patients undergoing abrupt discontinuation of ethanol or sedatives (including benzodiazepines such as Valium)[8]
- Nicotinic receptor antagonist varenicline (Chantix®) (Champix® in the UK)
- Recently, a shot given multiple times over the course of several months, which primes the immune to produce antibodies which attach to nicotine and prevent it from reaching the brain, has shown promise in helping smokers quit. However, this approach is still in the experimental stages. [5]
Alternative techniques
Some 'alternative' techniques which have been used for smoking cessation are:
- Hypnosis clinical trials studying hypnosis as a method for smoking cessation have been inconclusive. (The Cochrane Database of Systematic Reviews 2006, Issue 3.)
- Herbal preparations such as Kava and Chamomile
- Acupuncture clinical trials have shown that acupuncture's effect on smoking cessation is equal to that of sham/placebo acupuncture. (See Cochrane Review)
- Attending a self-help group such as Nicotine Anonymous[6] and electronic self-help groups such as Stomp It Out[7]
- Laser therapy based on acupuncture principles but without the needles.
- Quit meters: Small computer programs that keep track of quit statistics such as amount of "quit-time", cigarettes not smoked, and money saved.
- Self-help books (Allen Carr, FreshStartMethod etc.) Some of these claim very high success rates but little externally verified evidence of this success exists.
- Spirituality Spiritual beliefs and practices may help smokers quit.[8]
- Smokeless tobacco: Snus is widely used in Sweden, and although it is much healthier than smoking, something which is reflected in the low cancer rates for Swedish men, there are still some concerns about its health impact. [9]
- Herbal and aromatherapy "natural" program formulations.
- Smoking reduction utensil (minitoke)[9]
- Smoking herb substitutions (non-tobacco)[[10]]
Information for healthcare professionals
Clinical practice guidelines by the United States Preventive Service Task Force (USPSTF) in 2009 stated[10]:
- “The USPSTF recommends that clinicians ask all adults about tobacco use and provide tobacco cessation interventions for those who use tobacco products.” (Grade A recommendation)
The USPSTF has provided good evidence that demonstrates a clear benefit in both successful smoking cessation and greater than 1 year abstinence when clinicians provide smoking cessation interventions to adult patients. These interventions include behavioral counseling (<10 minutes) and pharmacotherapy. Brief smoking cessation counseling (3 minutes) though less effective, was found to increase quit rates.
A systematic review by the Cochrane Collaboration defined brief advice from a single verbal “stop smoking” statement to counseling up to 20 minutes and cited evidence that demonstrated when “assuming an unassisted quit rate of 2 to 3%, a brief advice intervention can increase quitting by a further 1 to 3%.[11]
Regarding individual studies, several have found that smoking cessation advice is not always given in primary care in patients aged 65 and older[12][13], despite the significant health benefits which can ensue in the older population[14].
Health professionals may follow the "five As" with every smoking patient they come in contact with:[15]
- Ask about smoking
- Advise quitting
- Assess current willingness to quit
- Assist in the quit attempt
- Arrange timely follow-up
