Rhode Island Marijuana Laws (2026): Possession, Limits and Where to Buy

By James Buddsey · Updated October 30, 2026

Yes. Under Rhode Island marijuana laws, adults 21 and older can legally possess up to 1 ounce of cannabis in public, keep up to 10 ounces at home and grow up to 3 mature plants per household, and buy from state-licensed retailers. Adult-use sales began on December 1, 2022, and as of October 2026 they still run through a small number of former medical dispensaries while the state works through a delayed round of new store licenses.

Rhode Island legalized adult-use cannabis with the Rhode Island Cannabis Act, which took effect May 25, 2022, and created a new regulator, the Cannabis Control Commission, to run the market. This guide is for residents and visitors who want the actual rules: how much you can carry, where you can use it, what it costs in tax, and what changed in 2025 and 2026. Each rule links to the statute behind it. It is general information, not legal advice.

Rhode Island Cannabis Laws at a Glance

Is Marijuana Legal in Rhode Island?

Yes, for adults 21 and over. The Rhode Island Cannabis Act, effective May 25, 2022, added chapter 21-28.11 to the state’s general laws. It defines adult-use cannabis as cannabis that “may be legally possessed and consumed for non-medical purposes” by a person at least 21 years old (§ 21-28.11-3).

The law let the state’s existing medical compassion centers apply to become “hybrid” retailers that sell to both patients and adults, and it barred any hybrid retailer from starting adult-use sales before December 1, 2022 (§ 21-28.11-10.1). Rhode Island’s medical program is older and continues under chapter 21-28.6.

Adult-use cannabis is still illegal under federal law, which matters at airports, on federal property and at state lines. See our federal marijuana law guide.

How Much Cannabis Can You Possess in Rhode Island

Under § 21-28.11-22, an adult 21 or older may:

• Possess, use and buy 1 ounce or less of cannabis, or the equivalent amount of cannabis concentrate, anywhere in the state.
• Keep up to 10 ounces per resident at a primary residence, in addition to lawfully grown live plants, as long as the cannabis is stored to meet the commission’s security requirements.
• Give away up to 1 ounce to another adult 21 or older, as long as nothing is paid and the transfer is not advertised or promoted to the public.

The statute sets no separate purchase cap; buying is protected within the 1-ounce possession limit.

Penalties for possessing more

Possession outside the Cannabis Act’s protections is handled under the state’s Uniform Controlled Substances Act (§ 21-28.11-27). Under § 21-28-4.01(c)(2):

• Possessing more than 1 ounce of marijuana is a misdemeanor punishable by up to 1 year in jail, a fine of $200 to $500, or both.
• For a person 18 or older who is not protected by the adult-use law, such as someone aged 18 to 20, possession of 1 ounce or less is a civil offense with a $150 civil penalty and forfeiture of the marijuana for a first or second violation within 18 months. A third offense within 18 months is a misdemeanor.

Where You Can and Cannot Use Cannabis in Rhode Island

The Cannabis Act bans smoking or vaporizing cannabis in any public place where tobacco smoking or vaping is banned, and in any place where cannabis use is banned, including by local ordinance (§ 21-28.11-22(e)). Section 21-28.11-29 adds specific places:

Not allowed

• School buses and school grounds
• Correctional facilities and licensed drug treatment facilities
• Public places where tobacco smoking is prohibited
• Any vehicle, aircraft or motorboat you are operating or controlling while under the influence
• Federal land, which follows federal law

Allowed, with limits

• Private homes, with the owner’s permission. Property owners are not required to allow cannabis use on their premises (§ 21-28.11-29(g)).
• Rentals: a residential landlord may ban smoking or vaping but may not ban non-smoked, non-vaped use, such as edibles, by a tenant who follows the law (§ 21-28.11-29(h)).

Buying Cannabis in Rhode Island

Adult-use sales started December 1, 2022, at hybrid retailers, which are compassion centers approved to sell to adults as well as patients (§ 21-28.11-10.1). Bring a valid government photo ID showing you are 21 or older. Visitors from other states can buy under the same 1-ounce limit as residents.

The Cannabis Act allows 24 new retail licenses spread across six geographic zones, with no more than four per zone. Six are reserved for social equity applicants and six for worker-owned cooperatives (§ 21-28.11-10.2). As of October 2026, none of those new stores has opened; the section on recent changes below explains why.

Cities and towns may regulate the time, place and manner of cannabis businesses, and may ban or restrict smoking and vaping cannabis in public places such as parks and beaches. They may not ban carrying cannabis through town (§ 21-28.11-16).

Medical Marijuana in Rhode Island

Rhode Island’s medical program runs under chapter 21-28.6 of the general laws. The Department of Health still issues registry identification cards to patients, while most other program powers moved to the Cannabis Control Commission (§ 21-28.11-10.1).

Under § 21-28.6-4:

• Patients may possess up to 2.5 ounces of dried usable marijuana (or the equivalent) and grow up to 12 mature and 12 immature plants, each with a valid plant tag, in an indoor facility.
• Primary caregivers may hold up to 12 mature plants and 2.5 ounces per connected patient, capped at 24 mature plants and 5 ounces in total, plus up to 24 immature plants.
• No more than 24 mature plants may be grown at one dwelling or commercial unit, regardless of how many cardholders live or work there.
• Out-of-state cards: a medical card from another state, a U.S. territory or Washington, D.C., “shall have the same force and effect” as a Rhode Island registry card.

Growing Cannabis at Home in Rhode Island

Adults 21 and older may grow cannabis at home. The limit in § 21-28.11-22(a)(2) is 3 mature plants and 3 immature plants per dwelling unit, and it applies “no matter how many persons reside at the premises.” Home grows must meet the commission’s security requirements.

Driving and Cannabis in Rhode Island

Driving under the influence of any drug is a crime under § 31-27-2. Unlike Washington, Rhode Island’s DUI statute sets no THC blood number; the test is whether the drug left you incapable of driving safely. Having a legal right to use the drug is not a defense.

The Cannabis Act adds that a person “shall not be considered to be under the influence solely for having cannabis metabolites” in their system (§ 21-28.11-29(a)(3)). A first-offense drug DUI carries a $500 fine and a license suspension of 3 to 18 months under § 31-27-2(d)(1)(iii).

Crossing State Lines, Airports and Federal Land

• Massachusetts and Connecticut: Both neighbors have legal adult-use markets, but carrying cannabis across any state line is illegal under federal law. See our Massachusetts and Connecticut guides.
• Flying: The TSA follows federal law and refers cannabis found at screening to police. Carrying cannabis on any flight is illegal under federal law, even one that lands in a legal state.
• Federal property: Military installations and other federal land follow federal law regardless of state rules.

Rhode Island Cannabis Taxes in 2026

Adult-use purchases carry three taxes under § 21-28.11-13:

• a 10% state cannabis excise tax on each retail sale,
• a 3% local cannabis excise tax on each retail sale, and
• the state sales tax of 7% under § 44-18-18.

That adds up to 20% on top of the shelf price.

Hemp, Delta-8 and THC Products in Rhode Island

Rhode Island regulates hemp under chapter 2-26, with the Cannabis Control Commission licensing hemp retailers. State law defines hemp by a delta-9 THC concentration of no more than 0.3%, and hemp-derived consumable CBD products may be sold only to people 21 or older (§ 2-26-3). Low-THC hemp products have been sold at licensed hemp retailers, including vape shops and liquor stores, since August 2024.

On July 18, 2025, the commission voted to pause new hemp retail and distributor licenses while it studied hemp-derived THC beverages, according to Rhode Island Current reporting. The commission posted its study in March 2026.

Federal law is about to tighten. A federal law signed November 12, 2025, moves hemp to a total-THC standard, caps finished products at 0.4 mg of total THC per container and excludes synthesized cannabinoids such as delta-8 made from CBD. Those rules take effect on November 12, 2026 for cannabinoids the plant cannot naturally produce, such as THC-O, and on December 11, 2026 for everything else, including delta-8. Most intoxicating hemp products now sold in Rhode Island will not meet that standard.

What Changed in Rhode Island Cannabis Law Recently

• New regulator in charge (2025): The Cannabis Control Commission’s final rules took effect May 1, 2025, and the commission replaced the Department of Business Regulation as the main cannabis regulator, as Foley Hoag reported.
• Retail license round halted (2026): Applications for the first 24 new retail licenses closed December 29, 2025. On April 8, 2026, a federal court issued a preliminary injunction that halted the licensing process in lawsuits challenging the requirement that a majority of owners be Rhode Island residents (Foley Hoag).
• Residency rule repealed (June 2026): Gov. Dan McKee signed two bills that removed the residency requirement, revised social equity criteria and voided the earlier application process. On July 24, 2026, the commission said it would refund prior applicants and run new application processes, with no confirmed launch dates at that time.
• Federal rescheduling (2026): State-licensed medical marijuana moved to Schedule III in April 2026. A broader DEA proceeding on all marijuana was stayed on September 29, 2026.
