Intelligence was measured in 907 children aged 8-13 years living in areas which differed in the amount of fluoride present in the environment . . . The development of intelligence appeared to be adversely affected by fluoride. A high fluoride intake was associated with lower intelligence. The effect of exposure to a high level of fluoride on intelligence may occur at an early stage of development of the embryo and infant when the differentiation of brain nerve cells is occurring, and development is most rapid.

Fluorides are violent poisons to all living tissue because of their precipitation of calcium.
They cause fall of blood pressure, respiratory failure, and general paralysis. Continuous ingestion of non-fatal doses causes permanent inhibition of growth. It is known as a scientific fact that fluoride is a deadly poison to enzymes, upon which all life depends. The terrifying conclusion of the studies was that fluorine greatly induced a cancer tumour growth. If doctors and the public can be made aware of this catastrophe, fluoridation shall end quickly.
