Focusing on the latest estimates of smoking cessation among U.S. adults, it was noted that the chance of succeeding in quitting smoking may be less among individuals with chronic obstructive pulmonary disease vs those without chronic obstructive pulmonary disease. Evidence-based treatments for smoking cessation continue to be a crucial part of a comprehensive strategy to assist all adults to quit and represent an especially vital element of chronic obstructive pulmonary disease management and care.

• This study included 161,233 ever smokers (12.8% with chronic obstructive pulmonary disease) from the 2018 Behavioral Risk Factor Surveillance System.

• Greater age-adjusted past-year quit attempts (68.8% vs 64.3%) but lower recent successful cessation (4.5% vs 5.8%) and quit ratio (53.2% vs 63.9%) were found in adults with chronic obstructive pulmonary disease who smoked vs those without chronic obstructive pulmonary disease.

• In adults with chronic obstructive pulmonary disease who smoked, a significantly higher percentage of past-year quit attempts but similar recent successful cessation and a significantly lower lifetime quit ratio were reported post-adjusting for covariates, relative to their counterparts without chronic obstructive pulmonary disease.
