Ballot initiatives are a practical way to pass marijuana legalization in states that allow them to change laws.
Eleven of the 19 states that have legalized adult use did it via ballot initiatives. The rest, and most recent, are the result of legislation moving through state chambers and signed by supportive governors. The latest state to succeed in this fashion was Rhode Island. A similar effort in Delaware ended with a veto.
So far three states - Maryland, Missouri and South Dakota - have confirmed cannabis initiaives in November. According to NORML, four more states are hoping to qualify.
ON THE 2022 BALLOT
Maryland
Like in New Jersey, the legislature punted the issue to voters, who will get to weigh in at the ballot in November. If passed, the Maryland Marijuana Legalization Amendment would amend the Maryland constitution.

Missouri
The Marijuana Legalization Initiative (Amendment 3) would amend the Missouri Constitution if it passes. It's being supported by the Legal Missouri 2022 PAC. The Act allows for home grow (6 plant) and would institute a 6% state sales tax.

South Dakota
Meassure 27 (the Marijuana Legalization Amendment) is on the 2022 ballot. In 2020, voters passed Amendment A by a 53% margin, but it was overturned by state courts.

Arkansas
Despite more than enough signatures submitted by Responsible Growth Arkansas, the state's Booard of Elections rejected the Arkansas Marijuana Legalization Initiative on a technicality. The campaign has filed a lawsuit with the state Supreme Court.
