One out of two smokers who smoke throughout their lifetime will die from a disease related to smoking. Tobacco smoking therefore represents a major global public health issue. Smoking is the leading cause of chronic obstructive pulmonary disease (COPD). Projections for 2020 indicate that by then, COPD will have become the third cause of death and the fifth cause of disability worldwide. Stopping smoking reduces the risk of developing COPD and is an essential treatment for this inflammatory disease. Smoking cessation decreases the prevalence of respiratory symptoms, number of hospitalizations, and decline in FEV1, as well as exacerbation frequency and overall mortality. Among the patients, 38-77% with COPD are smokers. Their daily cigarette consumption and level of nicotine dependence are often high. The combination of high intensity behavioral interventions and medication treatments (nicotine replacement therapy, varenicline, bupropion) is the most effective strategy for smokers with COPD. In contrast, behavioral interventions without medication are not more effective than simple advice to stop. Two factors seem to predict the success of the attempt to quit in smokers with COPD: a strong motivation to quit and the use of smoking cessation medications.
