The Food and Drug Administration has approved Florida’s request to import certain drugs from Canada, marking the first time a state has been authorized to buy lower-cost medications in bulk from abroad.

The historic move is the latest salvo in the long-running battle to lower drug prices, one of Americans’ biggest health care headaches and a major element of President Joe Biden’s reelection campaign. Florida Gov. Ron DeSantis, who is seeking the Republican presidential nomination, is also highlighting his importation proposal as he seeks to curtail drug costs.

While US law allows drug importation, it never gained traction because of federal health officials’ concerns over safety and actual savings as well as fierce opposition from American drug manufacturers and Republican lawmakers.
