The Minnesota Department of Health has linked severe vaping-related injuries to Vitamin E acetate in THC cartridges.
Products from 2019 were found to have the substance, but 2018 products obtained by law enforcement did not.
According to a release, the Center for Disease Control tested 29 samples of lung fluid from patients with vaping-associated lung injury, with five of those coming from Minnesota patients.
Vitamin E acetate was found in all fluid samples.
