A bipartisan group of U.S. lawmakers has reintroduced legislation that would ensure states have the right to enact their own marijuana coverages.

The Marijuana Business Daily reports the bills brought back into the House and Senate would create an exemption in the Controlled Substances Act to protect states’ capacity to determine their strategies without fear of reprisal that is federal.

Democrat Elizabeth Warren and republican Cory Gardner reintroduced the bill in the Senate.

The measure was brought to the House by Democratic Rep. Earl Blumenauer and Republican Rep. David Joyce — co-chairs of this Congressional Cannabis Caucus.

The bills could offer solutions to problems that have vexed the marijuana industry, like taxation and banking problems.
