There are so many bizarre levels in this whole issue, but one of them is the Food and Drug Administration that regulates medicine in this country. It has never regulated fluoride, either as a prescription medication, like vitamin tablets with fluoride in them, or for fluoride in the drinking world. They just wash their hands of this. And what this has meant, because the FDA has never regulated this, they've never required a randomized clinical trial to demonstrate effectiveness or safety. And after over 60 years, there has not been a single randomized clinical trial, the gold standard for testing drugs has never been applied to fluoride, either for effectiveness or safety. And it turns out, when you pursue this, that whilst there are agencies that promote this, like the Oral Health Division of the Center for Disease Control, they support and promote fluoridation all over the country. They give prizes and awards to individuals that are successful getting mandatory fluoridation or put the fluoride in the water, blah, blah, blah. They don't accept any responsibility for it. The EPA regulates contaminants in the water, but does not regulate additives. So the FDA doesn't regulate fluoridation, the EPA does not regulate fluoridation, the CDC promotes it, but doesn't accept responsibility for it. And when you're looking for, well, who is in charge, it turns out to be a private entity called the National Sanitation Foundation. Thank you.
