The purpose of this research study is to collect cells and liquid from the air passages of healthy adults, both smokers and non-smokers. These samples will be used for test-tube studies to explore mechanisms of diseases of the respiratory tract, and to compare the samples between people who smoke cigarettes and people who don't. Obtaining these samples requires an invasive procedure called "bronchoscopy".

Primary Outcome Measures:
  • The goal of this project is to define the effect of smoking on key aspects of airway biology. These studies will also provide crucial & novel definition of airway biology in smokers against which COPD & CF patients will be compared. [ Time Frame: At the time of bronchoscopy ]
