Is Marijuana Legal in Rhode Island?
Yes. Marijuana is legal in Rhode Island for adults 21 and older.
Rhode Island legalized recreational marijuana in May 2022 when Gov. Dan McKee signed the Rhode Island Cannabis Act. Legal recreational sales began on December 1, 2022.
Adults 21 and older may legally possess marijuana, purchase it from licensed retailers and grow a limited number of plants at home.
How Much Marijuana Can You Possess in Rhode Island?
Adults 21 and older may possess up to 1 ounce of marijuana outside their primary residence.
At a person’s primary residence, Rhode Island law allows possession of up to 10 ounces of marijuana per resident, in addition to marijuana produced by plants that are legally grown at the residence.
This means Rhode Island has a substantially higher possession limit for marijuana stored at home than for marijuana carried in public.
Can You Buy Marijuana Legally in Rhode Island?
Yes. Adults 21 and older may purchase marijuana from licensed retailers.
Adult-use customers may purchase up to 1 ounce of marijuana flower or its equivalent per day.
Rhode Island initially launched recreational sales through existing medical marijuana compassion centers authorized to operate as hybrid retailers. The state is also expanding the market with additional adult-use retail licenses under the Rhode Island Cannabis Act.
How Much Is Marijuana Taxed in Rhode Island?
Recreational marijuana purchases are subject to a combined 20% tax.
That consists of:
- 7% Rhode Island sales tax
- 10% state marijuana excise tax
- 3% local marijuana excise tax
Medical marijuana sales are exempt from both the 10% state marijuana excise tax and the 3% local marijuana excise tax, giving registered medical patients a significant tax advantage over recreational customers. Medical sales remain subject to the state’s general sales tax.
Can You Grow Marijuana at Home in Rhode Island?
Yes. Adults 21 and older may grow marijuana at home for personal use.
Rhode Island allows up to three mature marijuana plants and three immature marijuana plants per dwelling unit.
The limit applies to the entire dwelling rather than to each adult who lives there. A residence with multiple adults is therefore still limited to three mature and three immature recreational marijuana plants.
Plants must be grown indoors in a secure area with measures designed to prevent access by people under 21. Growers must also make reasonable efforts to prevent plants from being visible from streets or other public areas and to prevent marijuana odors from significantly affecting the surrounding area.
Unlike medical home growers, recreational home growers do not need to register their grow with the Rhode Island Cannabis Control Commission.
Can You Give Marijuana to Another Adult in Rhode Island?
Yes. An adult 21 or older may give up to 1 ounce of marijuana, or the equivalent amount of marijuana concentrate, to another adult 21 or older.
The transfer must be made without payment or other compensation and cannot be advertised or promoted to the public.
Selling marijuana without the appropriate state license remains illegal.
Is Marijuana Delivery Legal in Rhode Island?
Yes. Rhode Island regulations allow licensed marijuana retailers to provide home delivery after receiving approval from the Cannabis Control Commission.
Deliveries may be made to recreational customers who are at least 21 and to qualifying medical marijuana patients or caregivers. Marijuana must be delivered to a Rhode Island address, and the customer’s age or medical registration must be verified.
Home deliveries are generally limited to between 8 a.m. and 8 p.m., and cash payments cannot be accepted at the time of delivery.
Can You Use Marijuana in Public in Rhode Island?
Rhode Island law does not allow the smoking or vaporizing of marijuana in public places where tobacco smoking or vaping is prohibited.
Smoking or vaping marijuana is also specifically prohibited on school grounds, on public transportation, in correctional facilities and in certain other locations.
Property owners generally retain the authority to prohibit marijuana consumption on their property. However, landlords generally cannot prohibit tenants from consuming marijuana by nonsmoked and nonvaporized methods solely because the substance is marijuana, provided the tenant is otherwise complying with state law.
Is Medical Marijuana Legal in Rhode Island?
Yes. Rhode Island has allowed medical marijuana since 2006.
Registered patients with qualifying medical conditions may purchase marijuana through the state’s medical marijuana system and receive protections that go beyond those available to recreational consumers.
A registered patient may possess up to 2.5 ounces of dried usable marijuana or its equivalent.
Patients authorized to cultivate marijuana may also obtain a medical home-grow certificate allowing up to 12 mature and 12 immature marijuana plants. Rhode Island defines one medical “plant set” as one mature plant and one immature plant.
Medical patients also avoid the 10% state and 3% local recreational marijuana excise taxes imposed on adult-use purchases.
What Conditions Qualify for Medical Marijuana in Rhode Island?
Rhode Island’s qualifying conditions include:
- Cancer or cancer treatment
- Glaucoma or glaucoma treatment
- HIV or treatment for HIV
- AIDS or treatment for AIDS
- Hepatitis C or treatment for hepatitis C
- Autism spectrum disorder
- Post-traumatic stress disorder, for patients 18 and older
- Cachexia or wasting syndrome
- Severe, debilitating chronic pain
- Severe nausea
- Seizures, including those associated with epilepsy
- Severe and persistent muscle spasms, including those associated with multiple sclerosis or Crohn’s disease
- Agitation related to Alzheimer’s disease
A patient generally needs a practitioner to certify that the patient has a qualifying debilitating medical condition and that the potential benefits of medical marijuana are likely to outweigh the risks.
How Much Marijuana Can Medical Patients Grow in Rhode Island?
A qualifying medical marijuana patient who is authorized to cultivate may receive a home-grow certificate covering up to 12 plant sets.
Each plant set consists of one mature marijuana plant and one immature plant. That means an individual patient may be authorized for up to 12 mature and 12 immature plants.
Medical marijuana plants must be maintained at the registered grow location in a secure structure. Growers must also make reasonable efforts to prevent the plants from being visible from public areas and to prevent marijuana odors from significantly affecting the surrounding area.
A maximum of 24 medical plant sets, inclusive of applicable adult-use plants, may generally be located at a single dwelling or commercial unit regardless of how many patients or caregivers are associated with that location.
What Are the Penalties for Illegal Marijuana Possession in Rhode Island?
Although marijuana is legal, possessing more than the permitted amounts can still result in penalties.
For an adult 21 or older, possession of more than 1 ounce but no more than 2 ounces outside the home is generally a civil offense carrying a $150 penalty and forfeiture of the marijuana.
Possessing more than 2 ounces outside a primary residence is generally a misdemeanor punishable by up to one year in jail, a fine of up to $500, or both.
Possessing more than 10 ounces at a primary residence, excluding legally permitted live plants, is also generally a misdemeanor punishable by up to one year in jail and a fine ranging from $200 to $500.
Possessing more marijuana plants than legally authorized but fewer than 25 plants can result in a misdemeanor punishable by up to one year in jail and a fine of $200 to $500.
Possession of 25 or more unauthorized marijuana plants is a felony punishable by up to three years in prison, a fine of up to $5,000, or both.
Can Rhode Island Cities and Towns Regulate Marijuana Businesses?
Yes. Rhode Island cities and towns may impose reasonable local rules governing the time, place and manner in which marijuana businesses operate.
Local governments can address issues such as zoning, operating conditions and public nuisances, although local rules cannot conflict with the Rhode Island Cannabis Act or state regulations.
Local governments do not have authority to eliminate an adult’s statewide right to possess marijuana or cultivate marijuana at home within the limits established by state law.
Is Driving While High Illegal in Rhode Island?
Yes. Driving while impaired by marijuana remains illegal in Rhode Island.
The state’s marijuana legalization law specifically prohibits operating or being in physical control of a motor vehicle, aircraft or motorboat while under the influence of marijuana.
Rhode Island law also specifies that a person is not considered impaired solely because marijuana metabolites are present in their system.
Can You Take Rhode Island Marijuana Across State Lines?
No. Rhode Island’s legalization law does not authorize marijuana to be transported across state lines.
Marijuana remains prohibited under federal law, and transporting it from Rhode Island into another state can create legal consequences even when marijuana is legal in the destination state.
The same general restriction applies to marijuana purchased through Rhode Island’s medical marijuana program.
