I had read up about this happening awhile ago and had looked into it out of curiousity. I basically read the story of a French town where everyone went mad one day, and they linked it back to ergot, a form of mold that has similar properties to Lysergic acid diethylamide, better known as LSD.
I thought it was such an interesting story that this bread the town ate was infected with this mold, people went mad and danced in the streets. I used to experiment a lot in my younger days so I always find this kind of thing interesting. (Hey, I'm good now
Funnily enough, I came along this article today, about the same town and incident I had read about awhile ago, with new developments. The CIA is alledgedly behind the whole incident. French bread spiked with LSD in CIA experiment - Telegraph
I put this in the sensitive area due to drugs and CIA conspiracies.
What do you guys think? It seemed like such a neater story until I found out it's been linked back to CIA LSD experiments, though those are interesting as well. The idea of Ergot Madness affecting a whole town just always got me.
