![]() ![]() ![]() Data from a February 2020 study linked EVALI cases to vitamin E acetate, an additive in THC-containing vaping products.As of February 18, 2020, a total of 2,807 hospitalized EVALI cases had been reported to the CDC in the U.S. In August 2019, cases of e-cigarette or vaping use-associated lung injury (EVALI) sharply increased, afflicting e-cigarette users with respiratory and other symptoms, peaking in September 2019.A recent study found that e-cigarette users are five times more likely to test positive for COVID-19 than those who do not use tobacco products, and that dual users of cigarettes and e-cigarettes are nearly seven times more likely to test positive for the disease. There is growing evidence that using e-cigarettes can harm lung health and puts users at greater risk of contracting COVID-19.Thus, their health consequences are not well known when consumed in this manner. While many of the flavorings and humectants used in e-liquids have been approved by the Food and Drug Administration for oral consumption, they have not been approved for inhalation.Solutions, sometimes called e-liquids, almost always include nicotine, flavoring and a humectant, such as propylene glycol, to retain moisture and create the aerosol when heated.E-cigarettes are devices that operate by heating a liquid solution to a high enough temperature so that it produces an aerosol that is inhaled. ![]()
