Fluoride is the main component of psychotropic drugs and poisons for insects. In the United States during World War II it was a major waste from the construction of atomic bombs and aluminium aircraft parts. Large amounts of fluoride were very expensive in utilization so U.S. government decided to distribute this poison in toothpaste and water. Small doses of fluoride makes people more docile and susceptible to manipulation. The Nazis served fluoride to prisoners in the concentration camps. In addition, fluoride is responsible for the development of numerous diseases and cancers.
