CHICAGO: The U.S. Centers for Disease Control and Prevention released a series of reports on Friday indicating that the outbreak of vaping-related lung injuries appears to be waning, as evidence mounts that vitamin E acetate, a cutting agent used in marijuana vape cartridges, is playing a role in the illnesses.
Schuchat said THC vaping"largely explains" the big increase in acute cases that spiked over the summer, but the findings do not imply that nicotine vaping is entirely safe. In a second report in the New England Journal, researchers report that additional testing of lung samples from people who had vaping injuries strengthens earlier studies pointing to vitamin E acetate as a likely culprit in the outbreak.The study, which looked at lung samples from patients in 16 states, found vitamin E acetate in 94 percent of lung samples taken from patients who vaped THC.
