All 29 samples of lung fluids tested from vaping device users with severe lung injuries contained the oily additive vitamin E acetate, according to data published by the Centers for Disease Control and Prevention on Friday.
“These new findings are significant,” Anne Schuchat, CDC principal deputy director, told reporters in a press conference. It is the first time that a potentially toxic substance has been found directly at the site of injury in the lungs of vaping device users.
The severe lung injuries have puzzled health officials for months as a nationwide outbreak of the vaping-related illnesses erupted. Health officials now refer to the condition as EVALI, or “e-cigarette, or vaping, product use–associated lung injury.”
