To explore a potential connection to pesticides, epidemiologist Beate Ritz of UCLA and her graduate student Sadie Costello, now at the University of California, Berkeley, studied public records of pesticide applications in California's Central Valley from 1974 to 1999. Every application of pesticides to crops must be registered with the state. Working with Myles Cockburn of the University of Southern California, they developed a tool to estimate pesticide exposure in areas immediately adjacent to the fields.

They then identified 368 longtime residents who lived within 500 yards of fields where the chemicals had been sprayed and compared them with 341 carefully matched controls who did not live near the fields.

All so a politician can luck tough.

If anyone forgot paraquat was spread in huge amounts over marijuana fields in the Americas by the DEA.

Good clip
