In lab and mouse experiments, exposure promotes bacterial virulence and inflammation, while blocking the body’s ability to fight infection —
Researchers at the University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System report data suggesting that e-cigarettes are toxic to human airway cells, suppress immune defenses and alter inflammation, while at the same time boosting bacterial virulence.
