Florida Gov. Ron DeSantis signed a bill Thursday to ban fluoride in public water, making it the second state to do so.

Florida Gov. Ron DeSantis on Thursday signed a bill that will stop local governments from putting fluoride in water. The bill DeSantis signed doesn’t specifically mention fluoride. Instead, it bans local governments from putting anything in the water that doesn’t help with improving water quality or reducing contaminants.

With the stroke of a blue Sharpie, Gov. Ron DeSantis signed this year's "Florida Farm Bill," which among other things makes it against the law to fluoridate municipal water supplies.
