Asbestos

Well if you ate asbestos, that is not the issue. It is the inhalation.

Fiberglass is not thought or known to cause mesothelioma, which is the cancer caused by asbestos. The fiberglass particle sizes are too big to do what the extremely fine asbestos particles can do to lung cells. Does not mean that other issues are not happening with fiberglass.... if it gives your skin a rash, it's gonna effect your lungs similarly.

I worked in a dusty crawlspace for several weeks in the 70's that had fiberglass from the 30's in it that was all 'fried' out everywhere. Came out hacking for an hour or so every day for those weeks. Always have wondered if that had any long term effects. But, dang, exposure to gasoline and such around engines has been going on for me for 40+ years.
