CDC Identifies Vitamin E Oil Additive as a “Very Strong Culprit of Concern” in Vaping-Related Lung Injuries

VaporizerA representative at the US Centers for Disease Control for the first time today identified vitamin E acetate as a “very strong culprit of concern” in EVALI (e-cigarette or vaping product use-associated lung injury). Their announcement comes after health officials found the oil in the lungs of 29 patients sickened following their use of portable e-liquid vaporizers.

Writing in the agency’s journal Morbidity and Mortality Weekly Report, investigators concluded, “Based on these data from 29 patients, it appears that vitamin E acetate is associated with EVALI.”

“These findings provide direct evidence of vitamin E acetate at the primary site of injury within the lungs,” added Anne Schuchat, principal deputy director at the Centers for Disease Control and Prevention.

In early September, health officials in New York State publicly acknowledged finding high levels of Vitamin E oil in products suspected of being linked to the lung illness, which has been associated with over 2,000 cases nationwide and 39 fatalities.

The online publication has issued several extensive reports regarding the popularity of Vitamin E among illicit market vendors of e-liquid products. Their reporting indicates that beginning in late 2018, some vendors began to use the oil as an additive in an effort to thicken the consistency of their e-liquids and to mask dilution. Leafly’s latest reporting on the issue appears online here.

Other analyses have suggested that at least some lung-related injuries may be the result of the presence of a specific metal-binding agent in certain types of portable cartridges. Today’s CDC advisory does not rule out the possibility that other possible agents may also be playing a role in the illness, but affirms, “This is the first time that we have detected a potential chemical of concern in biologic samples from patients with these lung injuries.” The agency further adds, “The latest national and state findings suggest products containing THC, particularly from informal sources like friends, or family, or in-person or online dealers, are linked to most of the cases and play a major role in the outbreak.”
