We've come a long way from Nixon/Ford spraying paraquat on Mexican pot.
Paraquat Pot: The True Story Of How The US Government Tried To Kill Weed Smokers With A Toxic Chemical In The 1980s
Jerome London
Updated August 19, 2018 When people talk about “killer weed,†that’s typically understood to mean really good weed. But due to US government policies that started in the 1970s and extended through most of the 1980s, marijuana fields were being sprayed with a chemical that can actually kill you.
The chemical, known as “paraquat,†is an herbicide sprayed over marijuana fields in Mexico in the 1970s—with the aid of US money and US-provided helicopters—and over marijuana fields in Georgia in the 1980s under the direction of the Reagan Administration.
But normally, anything poisonous enough to kill plants is also toxic enough to kill humans, and that is the case with paraquat.
