July 25, 2012 — For years health experts have been unable to agree on whether fluoride in the drinking water may be toxic to the developing human brain. Extremely high levels of fluoride are known to cause neurotoxicity in adults, and negative impacts on memory and learning have been reported in rodent studies, but little is known about the substance’s impact on children’s neurodevelopment. In a meta-analysis, researchers from Harvard School of Public Health (HSPH) and China Medical University in Shenyang for the first time combined 27 studies and found strong indications that fluoride may adversely affect cognitive development in children. Based on the findings, the authors say that this risk should not be ignored, and that more research on fluoride’s impact on the developing brain is warranted. The study was published online in Environmental Health Perspectives on July 20, 2012. * This sentence was updated on September 5, 2012. Read a September 2012 statement by the authors.

Does fluoridated water help prevent tooth decay? Or does it cause illness? - Cleveland Plain Dealer Does fluoridated water help prevent toothdecay? Or does it cause illness? How much is too much? Story by FRAN HENRY Photos by BRYNNE SHAW She speaks softly, in pleasant, confident tones. "You don't want people to think you're nuts;' she says. Over the past two years, Schnall, a Bainbridge Township homemaker and the mother of two, has evolved into an anti-fluoride activist. "I don't think the issue is about tooth decay anymore;" says Schnall. don't believe that fluoride is an essential element to prevent tooth decay, and if it were, I still think there's too much out there, and it's linked to other illnesses." She says thousands of studies in medical journals worldwide document links between long-term fluoride ingestion and myriad illnesses and conditions, including thyroid disorders, cancer, mental retardation, osteoporosis, birth defects, infertility, organ failure, lead poisoning and learning disabilities, and an increased incidence of hip fractures in the elderly.

The U.S. is the world's largest consumer of hemp products, although growing hemp is illegal under federal law. Colorado recently passed a measure that legalizes growing hemp. Tim Sloan/AFP/Getty Images Hemp products for sale in Washington, D.C., in 2010. With recreational marijuana now legal in Colorado, small-scale pot shops will open up soon in places like Denver and Boulder. Why? As plants, marijuana and hemp look related, and they are. That might be news to farmer Michael Bowman's neighbors. Bowman is from Wray, a small town on the eastern Colorado plains. A Wonder Crop? Bowman will plant 100 acres of hemp this spring on his 3,000-acre farm, where the winter wind now whips across barren wheat and corn fields. hide captionDEA Special Agent Paul Roach says federal law does not distinguish between hemp and marijuana.

Top Bodybuilder Warns: Don’t Drink The Tap Water! [VIDEO Six time Mr. Olympia champion bodybuilder Dorian Yates warns against drinking fluoride in tap water. Yates explains how fluoride calcifies the pineal gland in the brain, what Rene Descartes called “the seat of the soul,” and claims that it could even be a conspiracy to block humanity reaching higher levels of spiritual awareness. Comments comments

Pineal Gland In the 1990s, a British scientist, Jennifer Luke, discovered that fluoride accumulates to strikingly high levels in the pineal gland. (Luke 2001). The pineal gland is located between the two hemispheres of the brain and is responsible for the synthesis and secretion of the hormone melatonin. Melatonin maintains the body’s circadian rhythm (sleep-wake cycle), regulates the onset of puberty in females, and helps protect the body from cell damage caused by free radicals. While it is not yet known if fluoride accumulation affects pineal gland function, preliminary animal experiments found that fluoride reduced melatonin levels and shortened the time to puberty. (Luke, 1997). The Pineal Gland Has Highest Levels of Fluoride in Body As a calcifying tissue that is exposed to a high volume of blood flow, the pineal gland is a major target for fluoride accumulation in humans. Fluoride and Earlier Puberty in Girls Farkas G, et al. (1983).

Farmers hope to plow the way for sustainable U.S. hemp A couple months ago, I asked if industrial hemp would make a resurgence thanks to new legalization and cultural acceptance of cannabis. A real hemp industry could be as much as 10 times bigger than legal marijuana, which is already a potentially $1 billion industry in Washington and $200 million in Colorado. But back in November, farmers were a little skittish. “Yes yes, the U.S. is the biggest consumer of hemp which is pretty damn sustainable compared to other fibers and grows relatively easily without a bunch of pesticides, but the federal government is crazy and they’re giving us so much money for all this corn!” Still, some farmers, like Michael Bowman in Colorado, are determined to cultivate the evil plant. Efforts to plant this seed aren’t just relegated to Washington and Colorado, with their newly legal marijuana. In Kentucky, the hemp-growing capital of the post-prohibition era, legislators are backing an initiative that would put cannabis back in the ground.

Does Pot Cause Mental Decline? A new study casts doubt on previous research linking early marijuana use to drops in IQ. WIKIMEDIA, BOGDAN GIUSCAA study claiming that pot use in youth has long-term cognitive effects is being challenged. The original study, published last year in the Proceedings of the National Academy of Sciences (PNAS), found that smoking marijuana as a teenager may be associated with IQ declines by middle age. The new study, published in the same journal on Monday (January 14), said that IQ declines were likely a product of socioeconomic status, Nature reported. “Although it would be too strong to say that the results have been discredited, the methodology is flawed and the causal inference drawn from the results premature,” Ole Røgeberg, the sole author of the new study and an economist at The Ragnar Frisch Centre for Economic Research in Oslo, wrote in the paper. Other research has shown that in the short-term, marijuana use is related to reversible problems with memory and focus.
