Federal health officials at the CDC have reported 450 possible cases of severe lung disease associated with electronic-cigarette product use or vaping.
Despite some reports that a compound called vitamin E acetate in some vaporizers may be causing the illnesses, Bharel said Wednesday that health officials haven’t found a single link to all the hundreds of reported cases.
It’s also not clear what’s causing the problem: nicotine, a marijuana compound, or an unrelated additive, Bharel said.
The only consistent feature among all the cases is that the patient reports using an e-cigarette within the last 90 days.
“It’s really concerning,” Bharel said at the press conference. “Any time we have a disease where we don’t understand what’s causing it, it understandably causes a lot of anxiety.”
