A second death has been linked to vaping in the US - this time in the state of Oregon.
A statement from the Oregon Health Authority (OHA) said reports were received that the individual, who died in July, had recently used a vape containing cannabis.
The statement said the individual's symptoms were consistent with those of more than 200 similar cases of nationwide respiratory illness.
Late last month, global media reported the death of a person in Illinois, which was said to be directly linked to their use of a vape.
Meanwhile, there was a major break on Thursday night (local time) on the US vaping crisis.
Public health officials say some of the marijuana products across the country contained the same chemical.

It's a type of oil made from Vitamin E - harmless when used as a supplement or for skin ointment - but apparently not safe for vaping.
"We don't yet know the exact cause of these illnesses - whether they're caused by contaminants, ingredients in the liquid or something else, such as the device itself," OHA public health physician Ann Thomas said in a statement.
CBS News on Thursday (local time) spoke with a young man who nearly died from vaping.
"I'm getting better now that I'm off oxygen, when I first got here it was like a baby bear was on my chest," 18-year-old Adam Hergenreder said.
When he got to the medical centre in Illinois on Saturday (local time), he was feverish, vomiting, and gasping for breath.
From what doctors know of his case, vaping nearly killed him.
Hergenreder told CBS he'd been vaping for two years.
The US Centers for Disease Control and Prevention has identified more than 200 cases like this nationwide, and the number is growing.
