Senate Democrats unveiled long-awaited legislation to end the federal prohibition of marijuana, but opposition from Republicans and some Democrats is expected to pose a challenge to passing the measure. Senate Majority Leader Charles Schumer (D-N.Y.) announced the bill, dubbed the Cannabis Administration and Opportunity Act (CAOC), in floor remarks. “I am proud to be the first Majority Leader ever to say that it is time to end the federal prohibition on cannabis, and this bill provides the best framework for updating our cannabis laws and reversing decades of harm inflicted by the war on drugs,” Schumer said. Schumer worked alongside Sens. Cory Booker (D-N.J.) and Ron Wyden (D-Ore.) to craft the legislation.
