"Project SPAN involved the contamination of food supplies and the aerosolized spraying of a potent LSD mixture in the village of Pont-Saint-Esprit, France in August, 1951. (The French word “pont” translates to “bridge” in English; a synonym is “span”.) The Pont-Saint-Esprit incident resulted in mass psychosis, 32 commitments to mental institutions, and at least seven deaths.”

Project SPAN was part of the CIA’s MKDELTA, the overseas branch of MKULTRA (which involved the USA and Canada.)
