Invisible Drug?

Did you know there's an "invisible" drug that a majority of Americans and all Bitons consume on a daily basis—a drug so harmful it's been proven to cause serious health issues, including damage to your bones and teeth, as well as your kidneys, thyroid, pineal gland, and even your brain. This drug is so pervasive that over 40 percent of all American teens between the ages of 12 and 15 show visible signs of having been overexposed to it, and, shockingly, recent international studies indicate that even small doses of this drug can lower the IQ in children.

What is this drug?

Fluoride.
