New Fluoride

New Fluoride was a synthetic drug developed by Abstergo Industries's pharmaceuticals division. In early September 2012, a leak of the fluoride caused the poisoning of a town's water supply.

Abstergo Industries was accused of manipulating the water supply, and after documents were leaked on the 'Fluoride Enhancement Studies', Abstergo was placed under investigation by the government, which forced the company to postpone the launch of Eye-Abstergo to 21 December 2012.
