Multicenter StudyEffectiveness of varenicline for smoking cessation at 2 urban academic health centers.
Smoking is a major cause of morbidity in lower socioeconomic groups. In randomized trials, varenicline improves long term quit rates, but effectiveness in a clinic setting is unknown. ⋯ In an inner city clinic, abstinence rates were lower than those in clinical trials and did not differ between varenicline and NRT.
