Colorado Pulmonary Alcohol Research Consortium
The purpose of this study is to figure out how substances from inside the lung work in cigarette smokers with heavy alcohol use, compared to cigarette smokers and non-smokers who do not drink heavily.

We are looking for volunteers to serve as control subjects to be compared to people who drink heavily in a research project that examines substances collected from inside the lungs.
Main Procedures Involved: • Thorough pulmonary evaluation by a lung
physician by physical exam, chest x-ray,
spirometry, and bronchoscopy
• Routine blood lab work & pregnancy test
will be performed
Duration of Participation: A single study visit from 7 AM to 12 PM during a weekday. Participants will need a negative COVID test 3-5 days before their visit.
