Dr. Leo Spira, M.D., Ph.D., M.R.C.S., London, Vienna and New York, is an internationally known and noted authority on fluorine poisonning. Dr. Spira states:
"Fluorine is a highly toxic substance, and its deleterious effect consists of depriving the body of calcium stored in the body as a material indispensable for sustaining the vitality of most of the organic functions, and of substituting sodium for the calcium which has been removed."
Heart and diabetic patients are warned against consuming sodium. Is this the reason for the great increase in death from these diseases in communities receiving fluoridation? (For instance, Grand Rapids, Michigan, U.S. A.). Dr. Spira further stated:
"To put it into a nutshell, fluorine is one of the most potent poisons known, and should be classified in a group together with arsenic, with which it has many characteristics in common. As a medical man, I have no hesitation in stating that the principle of adding a potent poison, such as fluorine into the public water supplies runs counter to every clinical, physiological and pharmacological doctrine, and should be categorically rejected by all means at the disposal of civilized man."
