Vape lung breakthrough suggests lethal culprit in THC products could be vitamin E acetate

Official word has come down from federal authorities on one potential cause of the mystery illness affecting vape users: Vitamin E acetate, a chemical found in some vaping products that has been demonstrated to linger in the lungs long afterwards. The finding has been called a breakthrough but is far from the last word on the situation.
Sadly, the condition has already claimed the lives of at least 39 people, and more than 2,000 cases have been reported collectively from every state but Alaska. At present the only advice offered has been to stop vaping altogether.
In a media teleconference, the heads of the investigation from the Centers for Disease Control and Prevention explained the basis for pointing the finger at Vitamin E acetate. The substance was cited as a possible problem early on but only recent testing has established it as a bona fide suspect, the team explained.
Samples taken from the lungs of 29 victims of the condition were sent in from 10 different states, and vitamin E acetate was found in all of them. These findings provide direct evidence of vitamin E acetate as the primary site of injury within the lungs, said Anne Schuchat, principal deputy director of the CDC .
Although she agreed that this evidence is a breakthrough, she noted that it is at present merely a correlative finding more research is required to establish causation, namely the mechanism of harm, though other work has been done in that area.
Previous non-CDC research suggests that when vitamin E acetate is inhaled, it may interfere with normal lung function, she said.
Its important to note that these findings do not rule out other possible compounds or ingredients that may be causing these lung injuries, she continued. There may be more than one cause of the outbreak.
