I ran across this MSDS a few days ago and didn't realize my toothpaste and my drinking water has this stuff in it. When we handled fluoride in the industry we had to wear respirators and hazmat suits, yet it is perfectly safe to be used in the water supply? The other thing they make with this is rat poison by the way. They say it is in incredibly low doses, then again so was lead and mercury back in the 70s.
