I can buy some of that. Burn pits in active war zones are a known source of cancer, half being in a constant vicinity of something burning and the other half being the properties of the aerosols produced by the thing being burned.

When a family member was diagnosed with cancer I was warned heavily about the difference between cooked meat and charred meat. Charring is linked to cancer where cooked meat is a bit more up in the air.
