Cannabis
in Rhode Island

Under the Rhode Island Cannabis Act of 2022, adults 21 and older may carry up to one ounce in public and keep up to 10 ounces at home. Having between one and two ounces in public is a civil violation rather than a crime, but more than two ounces in public, or more than 10 ounces at home, is a misdemeanor punishable by up to a year in jail and a fine of up to $500. Medical cardholders may possess 2.5 ounces and buy that amount every 15 days. Much larger quantities, especially with intent to distribute, carry long mandatory sentences, and penalties double within 300 yards of a school, park or playground.

Adult-use possession and purchase in Rhode Island are limited to people 21 and older under the Rhode Island Cannabis Act. The medical program, established by the Edward O. Hawkins and Thomas C. Slater Medical Marijuana Act, allows patients from age 18, and younger patients can enroll too, but a custodial parent or legal guardian must act as their caregiver or authorized purchaser and handle buying and administering the product. Some conditions carry their own age rules: PTSD qualifies only for patients 18 and over. Caregivers must be at least 21 and may assist no more than five patients.

Rhode Island allows home cultivation for both adults and medical patients. Adults 21 and older may grow up to six plants in a private residence, of which no more than three may be mature at any time. Registered medical patients have a much larger allowance of 12 mature plants and 12 seedlings, grown in an indoor facility. The medical program also allows cooperative cultivation, where registered members grow together: up to 24 mature plants and 24 seedlings at a residential site, or 48 of each at a non-residential one. Cooperatives must list every member on their application, be approved by the Department of Business Regulation, and grow only at the licensed premises.

The Rhode Island Cannabis Control Commission, a three-member body created by the 2022 Cannabis Act, handles licensing, enforcement and social equity programs for the cannabis industry, and it works alongside the Rhode Island Cannabis Advisory Board. Before the commission existed, the Office of Cannabis Regulation within the Department of Business Regulation filled that role, and older references to it still circulate. Patient registration is separate: the Rhode Island Department of Health administers the medical program, reviews certifications and issues cards. Municipalities also have a say, since each town decides whether to allow cannabis businesses, and at least 25 of the state's 39 municipalities have opted in.

Rhode Island taxes cannabis in a way comparable to alcohol, and medical patients pay noticeably less than other buyers. A medical cannabis data source reports a combined rate of about 20 percent on adult-use purchases, compared with about 7 percent for registered cardholders. Those figures come from a third-party source rather than the state tax division, and the research for this page does not break them into their component taxes or say whether municipalities add a local share, so buyers should treat them as approximate. The tax gap, together with the larger possession and home-grow allowances, is a large part of why some adults keep a medical card after adult-use sales began.

Rhode Island law, in Chapter 28.11 of Title 21, bars smoking or vaporizing cannabis on school buses, public transportation, school grounds, in correctional facilities, anywhere tobacco smoking is banned, and anywhere exposure would harm children. Where tobacco is allowed, cannabis may generally be smoked, subject to local rules and property owners' wishes, and municipalities may adopt ordinances regulating consumption. Landlords cannot stop tenants from using non-smoked forms such as edibles in their homes. The research for this page does not identify any licensed consumption lounge or permission for use at dispensaries, so on-site consumption at businesses appears to be unaddressed rather than authorized.

A Rhode Island medical card starts with a Practitioner Written Certification Form completed by an eligible provider. That includes MDs, DOs, advanced practice registered nurses and physician assistants licensed in Rhode Island, and, unusually, MDs and DOs licensed in Connecticut or Massachusetts. The patient then creates an account on the Rhode Island Licensing Portal and submits the application with the certification and proof of residency to the Rhode Island Department of Health. Before recommending cannabis, practitioners are expected to consider FDA-approved treatments. A third-party source reports that state processing takes around 35 days, so patients should plan for a wait before they can buy.

Rhode Island keeps a defined list of qualifying conditions, and practitioners may only certify patients for conditions on it. The list covers cancer, glaucoma, HIV and AIDS, hepatitis C, Alzheimer's-related agitation, and chronic or debilitating conditions causing cachexia, severe chronic pain, severe nausea, seizures or persistent muscle spasms. PTSD was added in 2016 and is limited to patients 18 and older. Autism spectrum disorder was added in 2018 after a Department of Health petition ruling; it requires an additional certification form and specific behavioral criteria, and for a minor the practitioner must first consult a pediatric subspecialist. Other conditions can be added through the Department of Health's petition process.

Applicants to the Rhode Island medical program must be state residents. The Department of Health expects proof of residency that shows the applicant's name, current address and a current date. Each application needs a Practitioner Written Certification Form from an eligible provider confirming a condition on the state list, and autism applications need an extra form. Patients under 18 must name a custodial parent or legal guardian as primary caregiver or authorized purchaser. Each patient may appoint only one primary caregiver, who must be at least 21 and may assist no more than five patients. Everything is submitted through the Rhode Island Licensing Portal. The research for this page does not state the current state application fee.

Rhode Island medical cards are valid for one year, so patients renew annually. Renewal follows the same path as a first application: a new Practitioner Written Certification Form from an eligible provider, submitted with current proof of residency through the Rhode Island Licensing Portal to the Department of Health. Because third-party sources report state processing times of around 35 days, starting a renewal well ahead of the expiration date is the practical way to avoid a gap. The research for this page does not identify a grace period after expiration or a specific window for early filing, and it does not give the current renewal fee.

Rhode Island's cannabis statutes and Department of Health materials in the research for this page do not address whether a practitioner may certify a patient by video, so the law appears silent on the question. In practice, at least one certifying clinic offers telehealth appointments for renewals while running in-person evaluations for new patients at a clinic in Cranston, which suggests providers treat first visits and renewals differently. Patients who want a remote certification should confirm with the provider and the Department of Health that it will be accepted, and should remember that certifying practitioners must be licensed in Rhode Island, Connecticut or Massachusetts.

Rhode Island recognizes medical cannabis cards issued by other states for patients with debilitating conditions, according to NORML's summary of the Rhode Island medical marijuana law. The research for this page does not spell out what visiting patients must show at a dispensary, whether they need to pre-register, or which purchase limit applies to them, so those details should be confirmed with the dispensary or the Department of Health. In practice, the question matters less than it once did: since adult-use sales began in December 2022, any adult 21 or older can buy at a licensed retailer without a card, subject to the one-ounce public possession limit and the higher adult-use tax.
