Smoking and Tobacco Cessation

Key Points

  • Use of tobacco is one of the leading causes of preventable illness in the U.S.; smoking accounts for approximately 20% of deaths.  
  • When tobacco is smoked, nicotine rapidly reaches peak levels in the bloodstream and enters the brain; if the smoke is not directly inhaled into the lungs, nicotine is absorbed through mucous membranes and reaches peak blood levels and the brain more slowly.
  • Although cigarettes are the most commonly used form of tobacco, other recreational tobacco formulations include conventional smokeless tobacco; compressed dissolvable tobacco; cigars; tobacco pipes and water pipes (i.e., hookahs); and electronic cigarettes (e-cigarettes).
  • The 2008 U.S. Public Health Service clinical practice guideline for treating tobacco use and dependence found that counseling and medication are effective when used by themselves for treating tobacco dependence; however, the combination of counseling plus medication was more effective than either method alone.
  • Because of the oral health implications of tobacco use, dental practices may provide a uniquely effective setting for tobacco use recognition, prevention, and cessation; dental professionals can help smokers quit by consistently identifying patients who smoke, advising them to quit, and offering them information about cessation treatment.
