I still think the Navajo Flu in the Four Corners area was the result of paraquat-laced pot rather than the highly improbable, and yet to be repeated, isolated outbreak of a rodent borne virus - Hanta, which had theretofore never been known to have crossed the Mississippi river.
I even had one CDC researcher in the early stages tell me that that was one agent under investigation until they all were given the party line to espouse.
The Feds had laced the sh*t to try and discourage the use while tracking the stuff at the same time some months (years?) before that event.
Oh my. I had not heard that one. Figures.
Hanta's all over the west now. Hundreds of cases have been reported to CDC since 2007.
