    An open-label, randomized, parallel-group, controlled study to evaluate changes in biomarkers of cigarette smoke exposure and biomarkers of potential harm in adult smokers who completely switch to using e-vapor products for 12 weeks

    Altria Client Services, Richmond, VA USA
    The purpose of this study was to characterize biomarkers of exposure (BOE) to select HPHCs and biomarkers of potential harm (BOPH) in adult smokers (AS) who switched to exclusive use of e-vapor products (EVPs) for 12 weeks. Method: Generally healthy...
