Rhode Island Medical Marijuana Program Details

Rhode Island's medical cannabis program has been operational since the law was signed in 2006 (R.I. Gen. Laws § 21-28.6). Approximately 22,494 patients are currently registered, according to the Rhode Island Department of Health.

Qualifying Conditions

The following conditions qualify a patient for the medical program (R.I. Gen. Laws 1956, § 21-28.6-3(9) (2006)):

  • Alzheimer's Disease
  • Autism
  • Cachexia
  • Cancer
  • Chronic pain
  • Crohn's Disease
  • Glaucoma
  • Hepatitis C
  • HIV/AIDS
  • Nausea
  • Persistent muscle spasms
  • Post-Traumatic Stress Disorder (PTSD)
  • Seizures
  • Other conditions subject to approval by the Department of Health

Possession Limits

Registered medical patients may possess up to two and one-half ounces of usable marijuana (R.I. Gen. Laws § 21-28.6-4(k) (2006)).

Caregiver Rules

Caregivers must be 21 years of age or older. A primary caregiver may assist no more than five qualifying patients. Each patient may appoint no more than one caregiver. These requirements are established under R.I. Gen. Laws § 21-28.6.

Reciprocity for Out-of-State Patients

Rhode Island extends reciprocity to out-of-state medical patients. A person holding a valid registry identification card, or its equivalent issued by another state, is authorized to engage in the medical use of marijuana in Rhode Island. A designated assistant for that patient is also authorized to help with medical use. Confirm current reciprocity procedures directly with the Rhode Island Department of Health, as operational details can change.

Home Cultivation Rules for Rhode Island Residents

Rhode Island allows home cultivation for medical cardholders. For adult-use home cultivation limits, consult official state guidance.

Medical Patient Cultivation

Under R.I. Gen. Laws § 21-28.6, a registered medical patient may cultivate:

  • Up to 12 mature marijuana plants
  • Up to 12 seedlings
  • All plants must be grown at a single location
  • The facility must be indoors

State-Licensed Cannabis Dispensaries and Retailers in RI

Medical Compassion Centers

Rhode Island law caps the number of state-licensed medical dispensaries, known as compassion centers, at no more than nine (R.I. Gen. Laws § 21-28.6). Medical dispensaries are operational. For a current list of licensed compassion centers and their locations, consult the Rhode Island Department of Health directly, as operational status can change.

Adult-Use Retailers

For information on state-licensed adult-use retailers, consult official state guidance. For details on the distinctions between medical and adult-use retail, including tax implications, consult official state guidance.

Federal vs. State Cannabis Law: Tax Implications for RI Businesses

State legality does not fix the federal tax problem. Every licensed medical cannabis business in Rhode Island, and any other state-legal cannabis business, faces a significant federal tax burden because cannabis remains a Schedule I controlled substance under federal law.

IRC §280E: The Core Problem

Internal Revenue Code § 280E disallows ordinary and necessary business expense deductions for any trade or business that traffics in Schedule I or II controlled substances. Because cannabis is still federally Schedule I, this applies to every state-legal cannabis business in Rhode Island. That means a dispensary cannot deduct:

  • Rent
  • Payroll (outside of direct production roles)
  • Marketing costs
  • Most operating expenses

The only meaningful deduction available is Cost of Goods Sold (COGS). A retailer can deduct the cost of acquiring or producing the cannabis it sells, but not the overhead that keeps the business running. This creates effective tax rates that can exceed 70% for some operators, compared to a standard business paying the statutory corporate rate.

Practical Impact on RI Operators

For Rhode Island dispensaries and cultivators, § 280E means financial modeling looks nothing like a conventional retail business. Operators need cannabis-specialized accountants who understand how to maximize COGS allocations within IRS guidance. Misclassifying expenses as COGS when they do not qualify is an audit risk.

Federal rescheduling of cannabis, currently the subject of pending DEA rulemaking, could change or eliminate § 280E's application. Until a final federal rule takes effect, assume § 280E applies in full. Do not rely on proposed rulemaking timelines for business planning.

Federal Tax Considerations

Cannabis businesses in Rhode Island face unique federal tax challenges due to the classification of cannabis as a Schedule I controlled substance. Under IRC § 280E, businesses trafficking in these substances cannot deduct ordinary business expenses, limiting deductions primarily to Cost of Goods Sold (COGS).

  • IRC § 280E prohibits cannabis businesses from deducting most ordinary and necessary business expenses, significantly impacting profitability.
  • Only COGS can be deducted, which includes direct costs of producing cannabis, but not general overhead expenses.
  • Businesses may need to use IRS Form 1065 or 1120 to report income and COGS, ensuring accurate tracking of deductible expenses.
  • The federal banking gap persists, as many banks are reluctant to work with cannabis businesses, leading to cash-heavy operations.
  • The SAFE Banking Act aims to facilitate banking access for cannabis businesses but has not yet passed the Senate, complicating financial operations.
  • Consult IRS Notice 2014-21 for guidance on the federal tax treatment of cannabis businesses and the implications of state legalization.
