In the 1960s, the Government sponsored a program called "Paraquat Pot" in which they sprayed the very harmful herbicide paraquat on marijuana fields in South America, which were distributed mostly to Americans. It was called Paraquat Pot.

Lung disease caused by the contact herbicide paraquat which selectively accumulates in the lungs and is highly toxic. Once X-rays show changes from paraquat are evident in the lungs, death is virtually certain.

Paraquat lung emerged as a health concern in the 1970s, when the US government sprayed paraquat aerially over some illegal marijuana fields in Mexico. Some of the sprayed plants were harvasted prematurely before they died, causing paraquat lung in purchasers who smoked it.
