Lung Cancer: Smoking Cessation.

Smoking cessation for patients who smoke should be a top priority for physicians. Nicotine dependence should be considered a chronic disease, with the expectation that relapse is normal. The US Preventive Services Task Force (USPSTF) recommends that physicians screen all adults for tobacco use, advise them to stop using tobacco, and provide behavioral interventions and Food and Drug Administration-approved pharmacotherapy for cessation to adults who use tobacco. It also recommends use of the 5 As (ie, Ask, Advise, Assess, Assist, Arrange) in discussing tobacco use with patients. All smokers should be offered behavioral and pharmacotherapy assistance in quitting. Pregnant women who smoke should be offered behavioral methods first. However, if these methods are unlikely to be effective, pharmacotherapy can be offered after a discussion about risks and benefits. The behavioral method with the most evidence of efficacy is group therapy. Nicotine replacement therapy (eg, gums, lozenges, transdermal patches, inhalers, nasal sprays), bupropion SR, and varenicline are approved by the Food and Drug Administration for management of nicotine withdrawal during smoking cessation.
