On September 16, 2020, the National Toxicology Program released a draft monograph on the Systematic Review of Fluoride Exposure and Neurodevelopmental and Cognitive Health Effects.
The report reconfirms that fluoride is "presumed to be a cognitive
neurodevelopmental hazard to humans" while claiming that the evidence is stronger and more consistent for studies in which subjects were consuming water fluoride at or above 1.5 ppm.
In this video, FAN's research director Chris Neurath and executive director Paul Connett drill down into the new report and discuss why the NTP's conclusions should effectively end water fluoridation as a public health policy.

![Debunked: Study Finding Huge Increase In IQ From Fluoride Exposure Is Biologically Impossible
During the Fluoride Lawsuit, EPA tried to use a single study from the Basque region of Spain that found a huge increase in IQ as a centerpiece of its argument that there was too much uncertainty to conclude fluoridated water was neurotoxic. Extensive testimony was obtained from both sides about this study, including almost two hours of deposition from the lead author of the Basque study, Jesus Ibarluzea. Tellingly, despite originally intended by EPA to be a star witness, Ibarluzea withdrew from the case before the trial, which may have further reduced the credibility of his study in the court’s eyes.
The court ruling addressed the Ibarluzea study in depth and agreed it had many of the problems that had been pointed out during trial testimony. The court’s ruling said:
“The reliability of Ibarluzea (2021) is questionable in several respects: ... [followed by 2 pages of detailed reasons why the court considered the Ibarluzea study of questionable reliability; Court ruling, pp. 27-29]
… as also explained previously, particular characteristics of these studies finding null outcomes render them less probative here.... Ibarluzea (2021) found an unrealistic 15-point IQ benefit, included unexplained and implausible results regarding creatinine adjustments, and failed to control for seafood [Court ruling, p. 39]
