More evidence supports the theory that vitamin E acetate in vaping products may be causing thousands of lung injuries and dozens of deaths among Americans.

Driving the news: Illegal THC-containing e-cigarette or vape products from 11 out of 12 patients in Minnesota with lung injuries also contained vitamin E acetate, according to a report from the CDC on Tuesday.

  • 20 THC-containing products seized during September 2019 contained vitamin E acetate, the study shows. But 10 products tested in 2018 before the outbreak began did not contain the ingredient.

What's happening: Vitamin E acetate is a viscous oil used as an additive in cannabis vape cartridges, allowing thicker clouds to be exhaled.

  • The oil is often used in foods and cosmetics and is not harmful when ingested. Vaporizing and inhaling vitamin E acetate, however, can cause fat to enter the lungs, leading to a sometimes fatal condition called lipoid pneumonia.

The backdrop: The FDA also tested several vape brands in October, which showed vitamin E acetate concentrations of 31% to 88% and lower-than-expected THC concentrations.

  • Most patients interviewed say they obtained these vaping products from black market retailers or from friends, the CDC says.

The bottom line: Health officials are still not ruling out other ingredients or causes of these cases, but cautioned vitamin E acetate should not be added to vaping products.

Biden adviser Cedric Richmond sees first-term progress on reparations

Illustration: "Axios on HBO"

White House senior adviser Cedric Richmond told "Axios on HBO" that it's "doable" for President Biden to make first-term progress on breaking down barriers for people of color, while Congress studies reparations for slavery.

Why it matters: Biden said on the campaign trail that he supports creation of a commission to study and develop proposals for reparations — direct payments for African-Americans.

Cyber CEO: Next war will hit regular Americans online

Any future real-world conflict between the United States and an adversary like China or Russia will have direct impacts on regular Americans because of the risk of cyber attack, Kevin Mandia, CEO of cybersecurity company FireEye, tells "Axios on HBO."

What they're saying: "The next conflict where the gloves come off in cyber, the American citizen will be dragged into it, whether they want to be or not. Period."

Cedric Richmond: We won't wait on GOP for "insufficient" stimulus

Top Biden adviser Cedric Richmond told "Axios on HBO" the White House believes it has bipartisan support for a stimulus bill outside the Beltway.

  • "If our choice is to wait and go bipartisan with an insufficient package, we are not going to do that."

The big picture: The bill will likely undergo an overhaul in the Senate after House Democrats narrowly passed a stimulus bill this weekend, reports Axios' Kadia Goba.
