The number of possible cases of severe respiratory illnesses among people who vaped nicotine or cannabis products has jumped by nearly 50% to 530 in 38 states and 1 territory, the Centers for Disease Control and Prevention announced Thursday.

Why it matters: There have been 8 confirmed deaths related to e-cigarette use, but no single product or substance has been definitively tied to the illnesses, the CDC said in its media briefing. This includes products purchased from unauthorized retailers. The CDC still advises that people should avoid using e-cigarettes.

“I wish we had more answers ... I know this is very frustrating for the public. This is very frustrating for us. This is a complex investigation."
— Anne Schuchat, principal deputy director at CDC

The CDC, Food and Drug Administration and individual states are having difficulty given the inconsistency of the cases. Some people are unable to talk about their illness given their symptoms, and in other cases, people are hesitant to disclose using illicit products.

  • The CDC says nearly three-quarters of patients are male, and two-thirds are 18–34 years old.
  • On Sept. 12, there were 380 cases in 36 states and 1 territory.
  • Most patients have reported a history of using e-cigarette products containing THC. Many patients have reported using marijuana and nicotine, while some reported the use of e-cigarette products containing only nicotine.
  • The FDA said Thursday that the agency's Office of Criminal Investigations has been pursuing a parallel investigation since the illnesses were first reported.

Background: Many states and the White House are pushing major anti-vaping efforts. Individual states are testing everything from banning flavored cartridges to public service announcements aimed at teens.

  • New data released Wednesday by the National Institute on Drug Abuse confirmed that the number of 8th-, 10th- and 12th-graders using e-cigarettes has doubled in the past 2 years.

What to watch: The agencies expect the number of deaths to rise.

In her three decades in science, Jennifer Doudna said she has seen a gradual erosion of trust in the profession, but the recent Nobel Prize winner told "Axios on HBO" that the institution itself has been under assault from the current administration.

  • "I think science is on the ballot," Doudna said in the interview.

Why it matters: That has manifested itself in everything from how the federal government approaches climate change to the pandemic.

Ted Cruz doesn't think the Hunter Biden attacks are working

Republican Sen. Ted Cruz told "Axios on HBO" he doesn't think the Trump campaign's focus on the Biden family's business dealings are having any sway with voters.

The big picture: After watching the Trump-Biden debate with "Axios on HBO" on Thursday night, Cruz said he thought Trump had done very well. But when asked whether he thought voters were moved by the release of the Hunter Biden emails, Cruz replied, "I don't think it moves a single voter."

Ilhan Omar: The Squad expects liberal turn from Biden after election

Rep. Ilhan Omar told "Axios on HBO" that given the way progressives have shaped Joe Biden's policy platform, she and other members of "The Squad" expect a liberal turn from him if he's elected.

Why it matters: Progressives have largely refrained from publicly criticizing Biden in the lead-up to the election, even though he hasn't signed on to their most far-reaching policies. Instead, they're focusing solely on beating Trump.
