The Trump administration said Thursday it will enforce federal laws barring the use of marijuana, reversing an Obama administration policy that gave wide latitude to states to determine their own pot laws. White House Press Secretary Sean Spicer said the Trump administration would prioritize enforcement in states that have passed laws allowing for the recreational—rather than medical—use of the drug.

Press Secretary Sean Spicer: “But I think the Department of Justice has the lead on that. It is something that you should follow up with them. But I believe that they are—they are going to continue to enforce the laws on the books with respect to recreational marijuana.”
