Study Links The Liquid Used In E-cigarettes To An Increased Risk Of Viral Infections
According to a published study by researchers at National Jewish Health in Denver, the liquid used in electronic cigarettes has been linked to a significantly higher risk of respiratory viral infections, whether the liquid contains nicotine or not.
For this study, researchers used a machine with human cells from the airways in a sterile container at one end, and at the other end they attached an electronic cigarette. The machine applied suction to the e-cigarette to simulate human use. The vapors produced by that suction traveled through tubes to the container holding the human cells and once there damaged the cells almost immediately.
