Lung injuries connected to the use of electronic cigarettes have topped 2,000 and killed 40 people, according to the Centers for Disease Control and Prevention.
It’s still unclear whether the cases are tied to legally sold products or devices modified by e-cigarette users, but the CDC this week identified a “potential toxin of concern”—Vitamin E acetate, which health officials detected in all 29 lung tissue samples from patients that they tested. The compound is used as an additive in THC-containing vaping products, and THC has been found in most of the samples the FDA has tested in connection to the illnesses.
There may be more than one cause of these illnesses, and the CDC continues its investigation. But this week, former FDA commissioner Scott Gottlieb said products made by market leader Juul should be removed from the market entirely. “It’s very clear that Juul can’t keep their products out of the hands of kids,” he told CNBC. “It could be that this product can’t exist on the market anymore.”
