PHUKET: I’ve been losing sleep lately thinking about all the poison I’ve subjected myself to during 12 years in Thailand – alcohol, sugar, fatty and acidic foods, traffic smog, secondhand smoke and perhaps the biggest culprit of them all: water.

I’m referring to fluoridated water, and the “forced-medication” of the planet’s prime life supply – drinking water.

The practice, which the US Centers for Disease Control once called “one of the 10 greatest achievements of the 20th Century”, is now one of the most heated health debates of our time, called by activist groups such as the Fluoride Action Network an “outdated form of mass-medication; an unnecessary, ineffective and unsafe practice”.
