They also looked at vaping cartridges collected from a dozen patients. Vitamin E acetate was commonly found in those, too. The study was small, but it echoes other work that found the compound in the damaged lungs of 29 patients across the country.
“The findings further support a potential role for vitamin E acetate in causing lung injury associated with vaping products,” said Dr. Ruth Lynfield, a Minnesota health official. Nearly 2,300 Americans who vape have gotten sick since March, many of them teens and young adults, according to a recent tally by the U.S. Centers for Disease Control and Prevention. At least 47 people have died.
Most who got sick said they had vaped liquids that contain THC, the high-inducing part of marijuana. Vitamin E acetate has recently been used as a thickener in illicit vaping products that contain THC, officials say.
