Brief Summary
Analysis of aldeyde biomarkers of exposure and host response The purpose of this prospective, open-label, clinical trial is to establish the feasibility and validity of exhaled breath condensate (EBC) biomarkers for use in studies designed to evaluate harm reduction strategies of smoking. This will be accomplished by measuring selected markers in EBC believed related to the pathogenesis of lung disease before and after a smoking cessation intervention.
