A 50-year mystery over the 'cursed bread' of Pont-Saint-Esprit, which left residents suffering hallucinations, has been solved after a writer discovered the US had spiked the bread with LSD as part of an experiment. In 1951, a quiet, picturesque village in southern France was suddenly and mysteriously struck down with mass insanity and hallucinations. At least five people died, dozens were interned in asylums and hundreds afflicted. For decades it was assumed that the local bread had been unwittingly poisoned with a psychedelic mould. Now, however, an American investigative journalist has uncovered evidence suggesting the CIA peppered local food with the hallucinogenic drug LSD as part of a mind control experiment at the height of the Cold War. One man tried to drown himself, screaming that his belly was being eaten by snakes. An 11-year-old tried to strangle his grandmother. Another man shouted: I am a plane", before jumping out of a second-floor window, breaking his legs. He then got up and carried on for 50 yards. Many were taken to the local asylum in strait jackets.
