Lung Damage

Progressive residue deposition inside the respiratory tract causes ongoing tissue damage. Tobacco residue accumulates progressively in the lungs over time. Tobacco residue buildup in the respiratory tract is analogous to soot and debris accumulating inside a chimney. E-cigarette users can experience lung lesions from inhaling aerosol. Young e-cigarette users have suffered lung collapses and pneumonia. Asthma has been documented in e-cigarette users without prior asthma history.
