Marijuana Convictions and Expungement: State-by-State Overview

Marijuana legalization has swept across the United States, but millions of people still carry convictions for conduct that's now legal in their state. In response, states have begun offering targeted expungement programs for cannabis offenses—some automatic, some requiring filing. Here's a practical overview of where things stand.

Why Cannabis Expungement Is Different

Most criminal record expungement requires waiting periods, filing fees, and individual petitions. Cannabis expungement programs are different because:

Legislatures have decided that prosecuting people for marijuana is no longer sound policy
Retroactively applying new standards to old convictions is a matter of fairness
Manual filing processes would overwhelm courts with millions of eligible petitions

For these reasons, many states have created expedited or automatic pathways specifically for cannabis convictions. The criteria, scope, and process vary significantly by state.

States with Automatic or Expedited Cannabis Expungement

California: California has been aggressive on this front. Under Proposition 64 and subsequent legislation, people with eligible marijuana convictions can have them redesignated or dismissed. The state's Department of Justice has run systematic review processes to identify and clear eligible convictions. In many counties, the process is moving toward automation with minimal required action from the person convicted.

Illinois: The Illinois Cannabis Regulation and Tax Act specifically required the governor to issue executive orders expunging low-level marijuana possession convictions. The state has cleared thousands of convictions through this mechanism. Illinois also created a process for people to petition for expungement of larger quantities or more serious offenses.

New Jersey: New Jersey's adult-use cannabis legalization included automatic expungement provisions for prior marijuana offenses. The state's approach involves identifying eligible records and processing them in batches, though implementation has faced delays.

Michigan: Michigan's clean slate law covers marijuana convictions alongside other eligible offenses. Misdemeanor marijuana possession convictions may be automatically sealed under the clean slate process if enough time has passed without new charges.

Colorado: Colorado passed legislation requiring courts to seal records for possession convictions that would not be criminal under current law. The process is largely automatic for people who file the correct forms, though some advocacy groups have pushed for fully automated processing.

States Requiring Individual Filing for Cannabis Expungement

New York: New York's Marijuana Regulation and Taxation Act created a process for sealing marijuana convictions, but the mechanism has been primarily petition-based. People with old marijuana convictions need to file motions to have their records sealed. The state has funded cannabis expungement clinics and legal assistance programs to help navigate the process.

Oregon: Oregon decriminalized marijuana and created a record-expungement process for prior convictions, but it still requires individual petitions. The state's process can be completed without a lawyer, but it requires paperwork and waiting periods.

Washington: Washington state has mechanisms for vacating marijuana convictions, but the process typically requires filing a motion with the court that originally sentenced you. Some counties have created streamlined processes; others require more individual effort.

States Where Cannabis Is Legal But Expungement Is Limited

Perhaps surprisingly, some states that have legalized marijuana haven't created robust expungement mechanisms for old convictions:

Minnesota: Despite legalizing cannabis in 2023, Minnesota has faced criticism for not establishing a clear automatic expungement process. People with old marijuana convictions may still need to file individual petitions, and advocacy groups continue to push for automatic clearance.
Montana: Montana legalized marijuana but expungement processes for prior convictions remain largely petition-based and not automatically applied.
New Mexico: Cannabis is legal but the expungement pathway requires individual filing in most cases.

Federal Marijuana Pardons

The Biden administration issued pardons for federal marijuana possession offenses in 2022 and 2024, covering conduct that remains illegal under federal law. These pardons are significant for people with federal convictions, but they don't affect state records. If your marijuana conviction was prosecuted at the state level, you'll need to work through your state's expungement process. Federal pardons also don't automatically clear records—people often need documentation to prove the pardon applies to them.

What to Do If You Have a Marijuana Conviction

Check your state's specific law. Use our state guides to understand whether your state has automatic expungement, petition-based expungement, or limited options for cannabis offenses.
Determine whether the conviction qualifies. Most programs cover simple possession, but some cover distribution or cultivation. The specifics matter.
Check if you're in a jurisdiction with automatic processing. Some counties and courts have been more proactive than others.
File if necessary. Even in states with automatic processes, if your record hasn't been cleared, it may be worth filing your own petition to ensure the record is addressed.
Get documentation. Keep copies of any expungement orders, pardons, or sealing orders. You'll need these in the future to demonstrate your record status.

The Bottom Line

Most states with legal marijuana have created at least some pathway to expunge or seal prior cannabis convictions, but the mechanisms vary widely. Some automatically clear eligible records; others require individual filing. If you have an old marijuana conviction, it's worth investigating your specific state's process—the law has changed rapidly, and your record may be eligible for clearance even if you've been told otherwise in the past.
