Officials from the Centers for Disease Control and Prevention stated that there had been a breakthrough in the study of the outbreak of vapor-induced lung injury, which killed 39 people and left more than 2,000 others ill.
Investigators said Friday they discovered a chemical compound called vitamin E acetate in all lung fluid samples from 29 patients who were hospitalized after vaporizing patients whose lungs were injured, saying THC – the major psychoactive component of marijuana – and in earlier tests, vitamin E was detected in samples of THC vape products.
Deputy Chief Director of the CDC, Dr. Ing. Anne Schuchat, reporters in a press report that "Vitamin E acetate is a well-known additive for diluting liquid in e-cigarettes or vapor products that contain THC."
eak began in March, scientists have been trying to find a common cause for the cases. For example, lung injuries have most commonly been associated with THC-containing products. However, some patients became ill after they claimed to have only evaporated nicotine.
The recent investigation revealed that Schuchat first said, "We have discovered a potential worrying toxin … These results provide a direct indication of vitamin E acetate at the primary site of injury in the lungs." THC was found in 23 of the CDC-tested lung fluid samples from 10 states.
Vitamin E acetate is found in many foods and is used in nutritional supplements and skin creams. It is generally safe to swallow or topically use, but it can be dangerous if inhaled. "If inhaled, vitamin E acetate may interfere with normal lung function," says Schuchat.
The outbreak of lung injury has recorded 49 states since March. According to the CDC, 2,051 people have become ill from the condition known as "e-cigarette or vaping, product use-associated lung injury" or EVALI.

Jim Pirkle, author of the CDC Overseeing labs testing lung lung injury patients, NPR's Richard Harris recently said it was a "Sherlock Holmes Exam."
He described vitamin E acetate as "oily – no ordinary oil but it is an oily substance. And so a large amount of vitamin E acetate would be something we want to make sure we analyze it. "
While the results released on Friday are considered significant, the CDC warns that there may be other factors in the process "Although it appears that vitamin E acetate is associated with EVALI, the evidence is not yet sufficient to rule out the contribution of other chemicals of concern to EVALI," the statement reads.
The CDC has Since the beginning of the outbreak, many warnings have been issued, including the recommendation not to vaporize products that contain THC It is also recommended not to buy steam products from the road or to make any changes to a steam product, unless the manufacturer intends to:
So far, the risk for THC steam products purchased online seems to be much greater, or inf Ormic sources. However, Schuchat also says that it is too early to say whether it is safe to use products from licensed pharmacies: "I think we do not know enough yet to completely disqualify pharmacies."
