CDC reports 'breakthrough' in vaping lung injury probe

The Centers for Disease Control and Prevention on Friday said a “breakthrough” was made in the investigation of vaping-related lung injuries in the United States which officials say, has topped 2,000 cases this week, and has killed at least 39 people.

That “breakthrough” was the discovery of Vitamin E acetate in all 29 patients sampled in a test by the CDC.

Vitamin E acetate is said to be used as a cutting agent in unauthorized products containing THC - the part of marijuana that gets people high.

The development comes on the same day President Donald Trump told reporters that the U.S. plans to raise the age limit for vaping to 21-years-old.

(SOUNDBITE)(ENGLISH) U.S. PRESIDENT DONALD TRUMP, SAYING:

"We're going to be coming out with a very important position on vaping. We have to take care of our kids most importantly. So we're going to have an age limit of 21 or so. But we'll be coming out with something next week, very important on vaping. You know, it's become a pretty big industry we're going to take care of. Now, there's also, you know, when you mention vaping you're talking about e-cigarettes, you're talking about a lot of different things, but we're coming out with a big paper next week."

Trump did not give any further details about the administration’s regulatory plans.

Nearly 85 percent of lung injury patients in the nationwide outbreak have reported using products containing THC.

This finding reinforces public health officials' recommendation that people avoid using e-cigarettes that contain THC or any products that come from illicit source.
