During the campaign, Donald Trump endorsed medical marijuana and said pot legalization “should be a state issue, state-by-state.” Attorney General Jeff Sessions, on the other hand, is a fierce opponent of marijuana and has opposed measures that would limit the federal government’s ability to interfere with state decriminalization efforts. Last month, Sessions reiterated the federal government’s authority to enforce federal drug laws “regardless of state law,” and some fear he will resist congressional efforts to protect medical marijuana from federal drug laws. Yet Sessions is not the greatest threat to continuing state-level marijuana reform efforts.
