Potential for electronic cigarettes (EC) to enhance lung tissue injury. Alcohol negatively impacts the lung via direct and indirect mechanisms. As with cigarette smoking, EC generate compounds known to enhance alcohol-mediated lung injury leading to both increased risk for infections and pneumonia as well as the exacerbation of existing chronic inflammatory lung diseases such as bronchitis, emphysema, and COPD.
