Marijuana-related legislation was on a fast track to nowhere until 2014. That was the year Republicans and Democrats alike approved a measure that kept federal authorities from interfering in states that allowed marijuana use for medical purposes.

Since then, both houses of Congress have seen a flood of similar proposals.

Lobbyists, policy experts and lawmakers who spoke to Roll Call said the trajectory is clear: Congress is leaning toward decriminalizing marijuana at the federal level — and it’s going to happen soon.

That could happen as early as the next Congress, to some time within the next 10 years.

To be sure, there are still many skeptics and stalwart opponents to the idea.
