Competing agendas have stifled the effectiveness of the burgeoning industry on Capitol Hill.

Marijuana advocates are stuck in the weeds.

Cannabis policy has never had a rosier outlook on Capitol Hill: Democrats control both Congress and the White House, seven new states just legalized recreational marijuana, and the cannabis industry has gained powerful new allies in companies like Amazon and conservative groups like Americans for Prosperity that are backing federal reform. The industry has even lured powerful advocates like former GOP House Speaker John Boehner and former Democratic Senate Majority Leader Tom Daschle to help push its agenda.

But nearly one year into this Congress, not one piece of cannabis legislation has been sent to the president’s desk. There is growing fear among advocates that the window to act is closing.

Industry lobbyists and legalization advocates say the movement has been stymied by a lack of consensus on the legislative strategy. Liberal advocacy groups are pushing for a comprehensive overhaul of federal cannabis policies with the aim of helping people harmed by criminal enforcement, while industry groups are seeking any piecemeal policy victory that could provide momentum toward more sweeping changes.
