The Colorado state Senate passed a bill on Wednesday to create the nation’s first state-run marijuana financial cooperative, with the ultimate aim of opening newly legalized cannabis retail outlets to key banking services through the Federal Reserve.

The 24-11 vote approving the so-called “cannabis credit co-ops” came days after the state House of Representatives cleared its own version of the bill, which seeks to address problems marijuana retailers face in having to operate on a cash-only basis.

House-Senate negotiators must now reconcile differences between the two versions in hopes of sending a compromise bill back for final floor votes in both chambers before the Democratic-controlled General Assembly session ends at midnight.

If they meet the deadline, the legislation will then head to Governor John Hickenlooper, a Democrat, who is expected to sign the bill into law.
