If marijuana is legalized, will charges be dropped? Not automatically. Whether an old marijuana conviction goes away depends on three things: which government prosecuted you, what the specific offense was, and whether the new law was written to reach backward and apply to conduct that already happened. Some people with federal simple possession convictions have already received relief through presidential pardons. Roughly two dozen states have passed laws letting people clear old marijuana convictions, but most of those states still require you to file something yourself.
Who Prosecuted You Decides What Can Help
The single most important question is whether your case was handled in state court or federal court. The two systems operate independently. A state’s decision to legalize marijuana and offer expungement has no power over a federal conviction. Only federal action, like a presidential pardon or a change in federal statute, can touch a federal case. And a state expungement law only reaches convictions entered under that state’s laws.
This trips people up because most marijuana arrests start with local police. But if a federal prosecutor took the case, perhaps because it involved large quantities or crossed state lines, the conviction is federal and federal rules govern what happens to it. If the case stayed in state court, your state’s legalization and expungement provisions are what matter.
Federal Marijuana Convictions
The main federal relief for past marijuana convictions came through two presidential proclamations. In October 2022 and again in December 2023, President Biden granted full, unconditional pardons to all U.S. citizens and lawful permanent residents who committed or were convicted of simple possession, attempted simple possession, or use of marijuana under federal law. The 2023 proclamation expanded coverage to include possession or use on federal lands and military installations.1The American Presidency Project. Proclamation 10688 – Granting Pardon for the Offense of Simple Possession of Marijuana, Attempted Simple Possession of Marijuana, or Use of Marijuana
Those pardons have hard limits. They don’t cover possession with intent to distribute, driving under the influence of marijuana, or any offense involving other controlled substances. They exclude anyone who wasn’t a U.S. citizen or lawful permanent resident at the time. And a pardon is not an expungement. It forgives the offense and removes civil disabilities like voting and jury-service restrictions, but it does not erase the conviction from your record.1The American Presidency Project. Proclamation 10688 – Granting Pardon for the Offense of Simple Possession of Marijuana, Attempted Simple Possession of Marijuana, or Use of Marijuana
Something to clear up: the federal government has not reclassified marijuana. As of early 2026, it remains a Schedule I controlled substance.2Office of the Law Revision Counsel. 21 USC 812 – Schedules of Controlled Substances The Department of Justice proposed moving it to Schedule III in May 2024, but the DEA administrative hearing was postponed in January 2025 pending an appeal.3Drug Enforcement Administration.

Increasing Medical Marijuana and Cannabidiol Research Even if rescheduling goes through, it would not legalize recreational possession or automatically clear old convictions.
State Convictions and the Retroactivity Question
Laws are normally forward-looking. A new legalization statute applies to conduct after its effective date, not before. For a legalization law to help someone already convicted, the legislature must deliberately include language that makes the law retroactive and authorizes courts to revisit old cases.
Not every state that legalizes marijuana takes that step. Some states legalize possession going forward and leave past convictions alone. Others build in explicit mechanisms for expungement, record sealing, or resentencing. The presence or absence of retroactive provisions is the biggest factor in whether legalization helps people with existing records. If your state legalized marijuana but didn’t include retroactive relief, a conviction for conduct that is now legal can remain on your record indefinitely unless the legislature acts again.
Which Offenses Qualify
States that offer retroactive relief do not apply it to every marijuana-related crime. Relief targets low-level, nonviolent offenses. The most common eligible charge is simple possession of a small amount for personal use, usually matching whatever quantity the new law permits. Some states also cover possession of paraphernalia or home cultivation of a small number of plants. A handful extend eligibility to low-level distribution, such as transferring a small amount, but the thresholds vary significantly by state.
Serious offenses are consistently excluded. You generally should not expect expungement relief for:
- Large-scale trafficking, meaning manufacturing or distributing commercial quantities
- Sales to minors, meaning any distribution involving someone under 18 or 21 depending on the jurisdiction
- Commercial grow operations outside the legal framework
- DUI charges involving marijuana
- Possessing a firearm during a drug offense
Weight thresholds matter more than people realize. If you were convicted of possessing four ounces but your state’s expungement law only covers convictions for one ounce or less, you don’t qualify, even though four ounces might now be legal to possess. The eligibility language in the expungement statute controls, not the quantity allowed by the legalization law.
How Charges Get Cleared
Clearing a record happens one of two ways: automatically, or by petition.
Automatic Expungement
A growing number of states have systems that clear eligible marijuana convictions without requiring the individual to act. California, Illinois, New York, Vermont, Connecticut, and several others have directed their courts or executive agencies to identify qualifying records and expunge them. In those states, you may already have a clean record. Timelines vary, and some programs have taken years to work through backlogs, so it’s still worth verifying your record even in an automatic-expungement state.
Petition-Based Expungement
Most states still require you to start the process yourself by filing a petition with the court where you were convicted. You’ll typically need your case number, date of conviction, and the specific offense, plus a showing that your conviction falls within the new law’s eligibility criteria. Court filing fees range from nothing to a few hundred dollars; some jurisdictions waive fees for marijuana-specific petitions. Processing takes anywhere from a couple of months to two years depending on the court’s backlog.
Common conditions beyond the offense type include completing the full sentence (including probation or parole), having no pending criminal charges, and sometimes a waiting period after the sentence ends. Missing any of these can get a petition denied even if the underlying offense qualifies.
Expungement, Sealing, and Vacating Are Not the Same
Expungement is the most thorough option; the conviction is effectively erased and records may be destroyed. Sealing hides the record from most public background checks but keeps it accessible to law enforcement and certain government agencies. Vacating a conviction nullifies the original judgment, as if the guilty verdict never happened, but the arrest record may still exist. Which remedy your state offers determines the practical benefit. An expunged record won’t show up on an employer’s background check. A sealed record might still surface in specific government screenings.
If You Are Not a U.S. Citizen
This is where state relief does the least work. Federal immigration law has its own definition of “conviction,” and it does not care whether a state has expunged, sealed, or vacated your record.5Legal Information Institute. 8 USC 1101(a)(48) – Definition of Conviction For immigration purposes, a conviction exists if a judge or jury found you guilty, or you pleaded guilty, and any punishment was imposed. State expungement doesn’t undo that.
Any non-citizen convicted of, or who admits to, a controlled substance violation is generally inadmissible to the United States.6Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens Because marijuana remains a federally controlled substance, state legalization has no bearing. The State Department’s Foreign Affairs Manual is explicit that whether a controlled substance is legal under state law is irrelevant to its illegality under federal law, and that state expungements generally do not remove a controlled substance conviction for immigration purposes.7U.S. Department of State. Foreign Affairs Manual – Ineligibility Based on Controlled Substance Violations
A narrow exception may apply to first-time simple possession offenders whose cases went through a state rehabilitative statute involving deferred adjudication or probation, but it is limited and fact-specific. If you are a non-citizen with any marijuana history on your record, including admissions made during a visa interview, talk to an immigration attorney before filing an expungement petition or traveling internationally. In some situations, a state expungement can actually draw attention to a conviction immigration authorities might otherwise not have noticed.
Firearm Rights After Expungement
Federal law prohibits certain convicted individuals from possessing firearms. Under federal law, a conviction that has been expunged, set aside, or pardoned is generally not treated as a conviction for firearms purposes, unless the expungement order specifically says you cannot possess firearms.8Office of the Law Revision Counsel. 18 USC 921 – Definitions State misdemeanor convictions punishable by two years or less generally don’t trigger the federal firearms prohibition in the first place. If a marijuana felony was later expunged under a legalization law, confirm with an attorney whether that restores your eligibility under both federal and state firearms rules, which don’t always line up.
What to Check About Your Own Case
Start with three things. Which government prosecuted you, state or federal. What specific offense appears on your record. Whether your state’s legalization law includes retroactive expungement provisions, and if so, whether it works automatically or requires a petition. For federal simple possession, you may already be covered by the 2022 and 2023 presidential pardons, though the conviction itself remains on your record. For state convictions, check whether your state runs an automatic program or expects you to file.
Don’t assume legalization took care of everything. People regularly discover years later that a conviction they thought was cleared is still on their record because the paperwork was never filed or an automatic system missed the case. Run a background check on yourself, check court records, and if you’re a non-citizen, speak to an immigration lawyer before anything else.
