Dozens of Florida municipalities have decided to stop adding floride to its drinking water over concerns the practice may be affect the cognitive ability of kids. Similar votes will soon be on tap in Clearwater and Manatee County.

Cities such as Melbourne, Port St. Lucie, Stuart, and Tavares have dropped fluoride over the past few months, taking their guidance from a directive issued by Florida Surgeon General Joseph Ladapo in November. Ladapo recommended against community water fluoridation “due to the neuropsychiatric risk associated with fluoride exposure.”
