these drugs are evil and basically are derivitives of lsd25 coming out of research into mind control. fluoride causes disfunction of the thyroid because the thyroid sees all halides the same and stores them and uses them to make hormones. the reason fluoride is used is because ti breaks through the blood/brain barrier, thereby delivering more of the drug to the brain with less dosage. i believe it is the most damaging class of drugs on the market.
