Paraquat lung

Paraquat (dipyridylium) is a highly toxic weed killer (herbicide). In the past, the United States encouraged Mexico to use it to destroy marijuana plants. Later, research showed this herbicide was dangerous to workers who applied it to the plants.

This article discusses the health problems that can occur from swallowing or breathing in paraquat.
