LOS ANGELES (AP) — It's a widely known vape cartridge in the marijuana economy, but it’s not a licensed brand. And it’s got the kind of market buzz no legitimate company would want.

The vape cartridges that go by the catchy, one-syllable name “Dank” _ a slang word for highly potent cannabis _ are figuring prominently in the federal investigation to determine what has caused a rash of mysterious and sometimes fatal lung illnesses apparently linked to vaping. Most of the cases have involved products that contain the marijuana compound THC, often obtained from illegal sources.
