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.^1-3 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,⁴ histologic evidence of long-term sequelae from vaping, outside the setting of EVALI, is largely lacking.
