The first draft of a long-anticipated Senate bill to federally legalize marijuana has been released—and its sponsors are asking for public input to further improve the legislation before it is formally introduced.

Senate Majority Leader Chuck Schumer (D-NY), Senate Finance Committee Chairman Ron Wyden (D-OR) and Sen. Cory Booker (D-NJ) are unveiling the draft at a press conference on Wednesday. It’s an extensive bill, titled the Cannabis Administration and Opportunity Act, that weighs in at 163 pages.

The main features of the legislation largely align with what advocates and stakeholders expected. It would federally deschedule cannabis, expunge prior convictions, allow people to petition for resentencing, maintain the authority of states to set their own marijuana policies and remove collateral consequences like immigration-related penalties for people who’ve been criminalized over the plant.
