The Dude: You thought that Bunny had been kidnapped and you were fucking glad man. You could use it as an excuse to make some money disappear. All you needed was a sap to in it on, and you'd just met me. You...you...human paraquat!
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.
Urban legend. Smoking marijuana sprayed with paraquat has no ill effects. The myth was propagated by anti-drug activists to deter the smoking of pot in general.
Gullible Moron: Oh shit, I hope I don't have the paraquat lung from this shwagg
Enlightened Skeptic: Don't worry, that's just a myth constructed by the fascists and religiousfundamentalists who want to legislate morality.
