50-State Comparison: Marijuana Legalization, Decriminalization, Expungement, and Clemency

Updated:  March 2020

Adapted with permission from Alana Rosen, High Time for Criminal Justice Reform (Feb. 1, 2019), with updates to reflect legislative changes.

As used here, legalization means certain acts are lawful; decriminalization means certain acts are punishable by fines but not incarceration (i.e. as infractions, petty offenses, minor misdemeanors, civil offenses, etc). In all states, certain acts remain punishable by incarceration: see NORML’s digest of marijuana penalties. Medical marijuana laws are not covered here.

*Does not include general record relief or pardon authorities that may cover marijuana among other offenses.

Alaska Stat. §§ 17.38.20-17.38.70.
CALegalization and decriminalization.
Cal. Health & Safety Code §§ 11357-11362.9.
Prob. 64 (2016) legalized marijuana and authorized individuals who had completed a sentence for a wide range of marijuana offenses to petition the court to either have the conviction dismissed and sealed, resentenced, and/or redesignated, depending on the offense. Cal. Health & Safety Code § 11361.8(e). Relief is mandatory, and no hearing is required. § 11361.8(f), (g).

AB 1793 (2018) replaced the requirement of individualized filings with an authority for systematic relief. Cal. Health & Safety Code § 11361.9. By July 1, 2019, the Department of Justice was to identify eligible cases for possible resentencing, redesignation, or dismissal and sealing, and notify the prosecution of all eligible cases in its jurisdiction. By July 1, 2020, the prosecution must determine and notify the court and public defender whether it will challenge any case on the basis of eligibility or that the person presents “an unreasonable risk to public safety.” The public defender must make “a reasonable effort” to notify the person whose potential relief is being challenged. If the prosecution does not challenge a case, the court automatically provides relief.

A 1976 statute provides that records of arrest and conviction for possession or transportation of small amounts of marijuana, adult or juvenile, “shall not be kept beyond two years from the date of the conviction or from the date of the arrest if there was no conviction . .. “ Cal. Health & Safety Code §11361.5. If the offense occurs on school property by a person under the age of 18, “the records shall be retained until the offender attains the age of 18 years at which time the records shall be destroyed.” Prop. 64 broadened this authority to apply to most marijuana offenses by individuals under age 18, and clarified that records must be “purged from the statewide criminal databases.” Id.
COLegalization and decriminalization.
CO Const. Art. 18, § 16(3)-(4); Colo. Rev. Stat. § 18-18-406.
Courts must, upon petition, seal the records of misdemeanor marijuana possession or use offenses that would not have been crimes if committed on or after December 10, 2012. Colo. Rev. Stat. § 24-72-710. Anyone convicted or charged with underage possession or consumption of marijuana may apply for sealing. § 18-13-122(13).
Conn. Gen. Stat. § 21a-279a.
Courts must, upon petition, order destruction of convictions and other criminal records in cases where the charges resulting in conviction have been decriminalized. Conn. Gen. Stat. § 54-142d; See also State v. Spielberg, 323 Conn. 756, 762–63, 150 A.3d 1118, 1121 (2016) (holding that, unlike the general rules of erasure set forth in § 54-142a, § 54–142d authorizes complete erasure in cases where the conviction was for conduct that has been decriminalized, even if charges dismissed in the case involved conduct that remains criminal, since § 54-142d contains no exception analogous to § 54-142a(g)).
11 Del. C. 16 § 4764(c).
"(i) Any person who was convicted of a single criminal offense under subsection (c) of this section, as it is in effect on or before July 31, 2019, and who was under the age of 21 at the time of the offense may, upon reaching the age of 21, apply for an expungement of the record of the conviction and any indicia of arrest to the court in which the person was convicted. For violations of a criminal offense under subsection (c) of this section, as it is in effect on or before July 31, 2019, an order granting such expungement shall issue upon proof that the person has reached the age of 21, unless the person has failed to comply with the sentencing order or the person has another charge under this section which remains outstanding . . . . (j) Notwithstanding any provision of law to the contrary, any person who prior to December 18, 2015, was convicted of a single offense arising from an original charge under this section or any predecessor statute, law or ordinance prohibiting the possession, use or consumption of marijuana or any controlled substance or counterfeit controlled substance classified in § 4714(d)(19) of this title shall be eligible for mandatory expungement of the records of the conviction and all indicia of arrest pursuant to the provisions of § 4373 of Title 11, provided the applicant is otherwise eligible for mandatory expungement as specified therein . . . ." 11 Del. C. § 4764(i),(j).
DCLegalization (Congress has blocked aspects, including sales) and decriminalization.
D.C. Law §§ 48–904.01, 48–1201; see, e.g., Pub. L. 113-235 (federal rider).
Persons with conviction and non-conviction records for decriminalized and legalized offenses may file motions to seal the records. D.C. Law § 16-803.02 ("(a) A person arrested for, charged with, or convicted of a criminal offense pursuant to the [D.C.] Code or...Municipal Regulations that was decriminalized or legalized after the date of the arrest, charge, or conviction may file a motion to seal the record of the arrest, charge, conviction, and related Superior Court proceedings at any time. (1)(A) The Superior Court shall grant a motion to seal if: (i) The arrest was not made in connection with or did not result in any other [D.C.] Code or...Municipal Regulations charges or convictions against the person; and (ii) The arrest was not made in connection with or did not result in any other federal charges or convictions....In cases that do not meet the requirements of paragraph (1) of this subsection, the Superior Court may grant a motion to seal if it is in the interest of justice to do so....").
Haw. Rev. Stat. § 712-1249.
A court must grant expungement, upon motion, of a conviction for possession of three grams or less of marijuana (decriminalized offense), if no other charges were brought. Haw. Rev. Stat. § 706-622.5(5).
ILLegalization and decriminalization.
410 Ill. Comp. Stat. Ann. 705/10-5.7, 20 Ill. Comp. Stat. Ann. 550/4.
In 2019, Illinois authorized the automatic expungement of arrests and convictions for “minor cannabis offenses,” defined as involving not more than 30 grams, no enhancements and no violence. Ill. Comp. Stat. Ann. 2630/5.2(i), (a)(1)(G-5). It also authorized expungement for misdemeanors and Level 4 felonies involving a greater amount of marijuana, upon petition by the individual affected or by the State’s Attorney.

Non-conviction records: The State Police and other law enforcement agencies are directed to “automatically expunge” the record of arrests one year after the date of the arrest, if no charges were filed or were filed and subsequently vacated, or if the person was acquitted. If the police are unable to determine disposition, they must expunge the arrest. See Timeline established for automatic expungement: post 2013 arrests to be expunged by 1/1/2021, those between 2000 and 2013 by 1/1/23, and those prior to 2000 by 1/1/2025. See Ill. Comp. Stat. Ann. 2630/5.2(i)(1).

Minor conviction records: A tiered procedure is established whereby “minor cannabis offenses” are subject to an automatic expungement (through a pardon authorizing expungement) administered through the Prisoner Review Board, while those convicted of more serious marijuana offenses (misdemeanor and Class 4 felony) must file a petition seeking expungement from the court.

For convictions in the first category, the State Police must notify the Prisoner Review Board of convictions not associated with violence, the PRB in turn notifies the relevant State’s Attorney who may object on eligibility grounds only, and the PRB makes a confidential recommendation to the governor. When the governor has granted a pardon authorizing expungement, the PRB files with the court asking for expungement of the record. The court is responsible for notifying the individual at his or her last known address. See Ill. Comp. Stat. Ann. 2630/5.2(i)(2).

For marijuana offenses in the second category (misdemeanor and Class 4 felony), individuals must file a petition with the court, and expungement may be granted after a hearing where the court applies a balancing test. An individual may file “after completion of any non-financial sentence or non-financial condition imposed by the conviction.” State’s Attorneys are also authorized to file petitions to vacate and expunge the record of conviction. Civil legal aid organizations may file petitions including more than one name. In considering motions to vacate and expunge a conviction the court shall consider the reasons to retain the records, the person’s age, the person’s age at the time of conviction, and the specific adverse consequences if denied. Ill. Comp. Stat. Ann. 2630/5.2(i)(3)-(5).
As discussed in the previous column, Illinois authorized automatic expungement of “minor cannabis offenses” which includes sending eligible convictions to the governor through the Prisoner Review Board for a pardon authorizing expungement. In December 2019, Governor Pritzker issued pardons to 11,017 people with eligible convictions.
