Brief Summary:
To test the hypothesis that treatment with the inverse agonist nadolol will improve smoking cessation in patients with chronic cough associated with long-term smoking, with or without airflow obstruction, including those with established chronic obstructive pulmonary disease (COPD) (chronic bronchitis dominant) or non-obstructive chronic bronchitis (NCB), compared to placebo and standard of care, while undergoing a validated smoking cessation program.

  8. Self-reported prior failure(s) to quit smoking during participation in a smoking cessation program.
  9. Able to complete diary cards and comply with study procedures.
  10. Females of childbearing age may participate only if they have a negative pregnancy test, are non-lactating, and agree to practice an adequate birth control method (abstinence, combination barrier and spermicide, or hormonal) for the duration of the study.
