Pharmacologic approaches to smoking cessation.

Abstract

Cigarette smokers experience greater rates of morbidity and mortality. Despite the known health risks, use of tobacco products remains high throughout the United States (approximately 19.3% of adults). Tobacco use is associated with higher rates of cardiovascular illness, cardiovascular risk factors (ie, hypertension and atherosclerosis), chronic obstructive pulmonary disease, emphysema, and various types of cancer. Pharmacologic smoking cessation therapies have been used to facilitate abstinence from smoking. This article provides clinicians with instructions for the use of pharmacologic agents for smoking cessation, including considerations for special populations.
