The CDC said Friday that no one e-cigarette or vaping product has led to an outbreak of a severe lung disease that is sickening users across the country.

According to a CDC press release,215 e-cigarette and vape users in 25 states have been sicked by a serious lung disease since August. That number does not include cases still under investigation.

At least three people have died as a result of the disease.

The Washington Post reports that there have been 450 cases of serious lung disease in 33 states, dating back to early summer.

The CDC reported Friday that of all those sickened by the lung disease, many — but not all — reported using vape products containing THC. The agency did note that there were also some reports of patients using both THC and nicotine products, and a smaller group of patients that were only using nicotine products.

The CDC's update came a day after the New York State Department of Health said it believes Vitamin E acetate — a substance found in cannabis e-cig products — was likely the culprit of the disease. While the CDC did say that they believe the cause of the disease is "likely associated with chemical exposure," they said it was "too early to pinpoint a single product or substance common to all cases."
