TheCannabis Administration and Opportunity Act (S.4226 in the 118th Congress) is a proposed bill in the United States Congress to recognizelegalization of cannabis by the states. The authors are Senate Majority LeaderChuck Schumer, SenatorCory Booker, and SenatorRon Wyden.
On March 31, 2021, following New York legalization under the 2021Marijuana Regulation and Taxation Act, Senate Majority Leader Chuck Schumer announced he would soon introduce a federal bill to deschedule cannabis, similar to his 2018Marijuana Freedom and Opportunity Act.[1] Sources toldPolitico and other media that a draft of the bill would be introduced on July 14.[2]
On July 14, 2021, Senator Schumer introduced adiscussion draft of the bill.[3][4]
On February 4, 2022, Schumer said the legislation would be introduced in the U.S. Senate in April of that year.[5] Later in February, Schumer circulated a letter asking other senators to "join the process of perfecting" the draft, and for their support.[6] The bill was said to be likely to be introduced by its sponsors on or around the unofficial420 cannabis holiday, i.e. April 20, 2022,[7] but it was later postponed to "before August recess".[8]
The bill was introduced in the United States Senate on July 21, 2022 as S.4591.[9][10] In addition to decriminalizing cannabis at the federal level, the bill would expunge federal cannabis-related criminal records. It would add new funding for law enforcement to go after illegal marijuana operations.[9]

In aDear Colleague letter, Senate Majority Leader Chuck Schumer and others announced plans to reintroduce the Cannabis Administration and Opportunity Act before April 20, 2024.[11] Schumer announced the introduction of the bill on May 1, 2024,[12] and it was enrolled as S.4226 that day.[13]
The bill was called by ABC News in 2021 "the first time in history [senators from a major party] introduced a bill to decriminalize marijuana at the federal level and remove cannabis from the federal list of controlled substances" and end federal prohibition.[14][a]
The New York Times wrote that the bill was unlikely to become law, but was significant because "[t]he suggestion that the Senate's top leader and the chairman of the powerful Finance Committee would sponsor major decriminalization legislation would have been fantastical in the not-too-distant past".[16]
The Associated Press wrote that the support of the Senate Majority Leader for ending prohibition "underscor[es] how a once-fringe idea is increasingly mainstream".[17]
Sen. Chuck Schumer, D-N.Y., held a press conference with other Democratic lawmakers to introduce the Cannabis Administration and Opportunity Act. The legislation will aim to change the federal government's approach to handling marijuana, as the Biden administration plans to reclassify the drug.
