Progress and opportunities in tobacco control.

Much progress has been made in reducing tobacco use in the United States. Despite the continuing challenges of tobacco control and the massive burden of illness, death, and economic costs caused by tobacco products, there are now unprecedented opportunities to prevent and treat tobacco dependence through a combination of interventions that have proven effective at both the population and individual levels. This report briefly reviews population trends in tobacco use by youth and adults, describes some of the policy measures that have proven effective in comprehensive tobacco control, and discusses the role of clinicians in the diagnosis and treatment of tobacco dependence in patients.
