The CDC announced Friday that THC vape products have been linked to a majority of patients with vaping-related lung injuries, citing to data from 1 local and 1 national study.

Why it matters: While the CDC is not shifting its focus away from nicotine, officials said 77% of those with exposure histories reported using products that contain THC, the psychoactive component in marijuana, or both THC-containing products and nicotine-containing products.

What's happening: There are 805 confirmed and probable cases of lung injury and 12 dead associated with e-cigarette use in 46 states and 1 U.S. territory.

  • The national study contained 514 patients, and 36% reported exclusive use of THC-containing products while 16% reported exclusive use of nicotine-containing products.
  • Officials also cited a report from Illinois and Wisconsin which said that a vast majority of 89 people used THC products. The products were packaged, pre-filled cartridges and primarily acquired from "informal sources" like friends and family, illicit dealers or off the street.

Where it stands: The CDC and health officials still cannot identify a definite product or source. Acting FDA Commissioner Ned Sharpless told a congressional committee on Wednesday that investigators are working to identify the toxic products and "follow the supply chain to the source."

  • "To be clear, if we determine that someone is manufacturing or distributing illicit, adulterated vaping products that caused illness and death for personal profit, we would consider that to be a criminal act," he said.

64% of people from around the world say climate change is a global emergency, a United Nations poll published Wednesday finds.

Why it matters: It's biggest global survey on climate change ever conducted, with some 1.2 million participants from 50 countries — including the U.S. where 65% of those surveyed view climate change as an emergency.

Collins helps contractor before pro-Susan PAC gets donation

A PAC backing Sen. Susan Collins in her high-stakes reelection campaign received $150,000 from an entity linked to the wife of a defense contractor whose firm Collins helped land a federal contract, new public records show.

Why it matters: The executive, Martin Kao of Honolulu, leaned heavily on his political connections to boost his business, federal prosecutors say in an ongoing criminal case against him. The donation linked to Kao was veiled until last week.

How cutting GOP corporate cash could backfire

Companies pulling back on political donations, particularly to members of Congress who voted against certifying President Biden's election win, could inadvertently push Republicans to embrace their party's rightward fringe.

Why it matters: Scores of corporate PACs have paused, scaled back or entirely abandoned their political giving programs. While designed to distance those companies from events that coincided with this month's deadly siege on the U.S. Capitol, research suggests the moves could actually empower the far-right.
