Chronic Airway Disease and Vaping - A First Step

Chronic Airway Disease and Vaping - A First StepThe 2019 outbreak of acute lung disease associated with vaping led to the characterization of electronic cigarette (e-cigarette) or vaping-associated lung injury (EVALI), which primarily corresponds histologically to diffuse alveolar damage, acute fibrinous and organizing pneumonia, or organizing pneumonia on its own. Although at least one case report described respiratory bronchiolitis in a surgical lung biopsy from a former smoker with persistent fixed airway obstruction after 9 months of vaping, histologic evidence of long-term sequelae from vaping, outside the setting of EVALI, is largely lacking.
