Rhode Island has quite an interesting relationship with marijuana. The state banned the sale of pot as early as 1918 and up to 2012 it had some of the strictest mandatory minimums for large-scale cannabis possession in the US. There were also numerous attempts to introduce bills to legalize recreational weed in the Ocean State since 2011, but not one came to fruition. But since 2006, medical marijuana has been legal in the state and a cannabis dispensary system was even introduced two years after, making it the second in the US just after California. In addition to this, there’s also a religious sect called the Healing Church in Rhode Island that uses cannabis in its rituals. Because of this, the church has had a number of run in’s with the law over the years. 

Today, adult-use marijuana is legal in Rhode Island after Gov. Dan McKee signed the Rhode Island Cannabis Act in May 25, 2022. The bill, which was sponsored by by Rep. Scott Slater and Sen. Josh Miller, legalized possession of up to an ounce and home cultivation of up to 3 mature plants and 3 immature ones. It also established a recreational marijuana market and a process to expunge prior weed possession misdemeanors or felonies by July 1, 2024.

Overview of Cannabis Growing Laws in Rhode Island

Rhode Island marijuana laws are fairly generous when it comes to home cultivation of medical marijuana.

  • Registered medical marijuana patients and their designated caregivers are allowed to cultivate up to 12 mature plants and 12 immature ones.
  • Caregivers may have up to 5 patients under them. However, they can only grow a total of 24 mature plants and 24 immature ones at a single location.
  • The plants must bear valid tag certificates purchased from the DBR.
  • Patients and caregivers may participate in cooperative cultivation where they can grow in a residential or non-residential location. Up to 24 mature and 24 immature plants can be grown in a residential location and twice that number in a non-residential location.
  • Marijuana plants should be cultivated in a locked indoor space away from public view.

Meanwhile, those who want to grow marijuana for recreational purposes may raise a total of 6 plants, with only 3 mature ones at a given time.

Punishments for Violating Rhode Island’s Home Grow Laws

The state used to have one of the highest marijuana use rates of any non-recreational states and even some recreational states. Here are some factors that may have contributed to this:

  • The qualifying conditions for medical marijuana are vague and can be easily abused
  • It’s difficult for authorities to know who is growing illegally 
  • The marijuana black market in the state is difficult to regulate
  • Possession of less than an ounce of recreational marijuana is only a civil violation punishable by a fine of $150.

Even though adult-use marijuana is now legal in Rhode Island, it is still not a good idea to take the law lightly since heavy penalties are in store for those who violate them.

  • Patients and caregivers who go over the cultivation limit automatically lose legal protection and may be subject to arrest and prosecution under the Rhode Island controlled substances act.
  • While possession of more than an ounce to 1 kg is only a misdemeanor punishable by a $500 fine, getting caught selling more than 1 ounce to 1kg is already a felony punishable by a maximum sentence of 30 years in prison and maximum fine of $100,000. Prison time and fines get much steeper as the amount that you illegally possess, sell/distribute, or cultivate increases.

History of marijuana in Rhode Island

Rhode Island has historically been tough on recreational marijuana but a bit more accepting of its medical use. The state prohibited cannabis sales without a prescription in 1918, just 4 years after New York issued the first instance of marijuana regulation. Like most other states, it took Rhode Island almost a century before acknowledging the medical benefits of cannabis for patients with debilitation conditions. In 2006, the Ocean State finally legalized medical marijuana by approving The Edward O. Hawkins and Thomas C. Slater Medical Marijuana Act. 3 years after, Rhode Island also became the second state in the US to introduce a dispensary system right after California.   

Even with just the legalization of medical marijuana, Rhode Island already has one of the highest rates of marijuana use in the US. It is very likely that the state will just have to accept that reefer use is here to stay and it is best to just regulate recreational marijuana and profit in the process rather than suppressing it altogether. Given that the incumbent governor has already drawn up plans to legalize recreational marijuana in 2018, approval of a bill may happen within the next two years.

Growing Medical Marijuana in Rhode Island

To grow medical marijuana under Rhode Island marijuana laws, you have to be a resident 21 years and older and registered as a patient or caregiver in the state’s medical marijuana program. Patients must have a qualifying condition and while minors can be registered as patients, they can only consume but not grow. Meanwhile, caregivers have to be designated by their patients in their application. A caregiver may grow for up to 5 patients.   

To register, patients need to submit a completed copy of the New Patient Application Form along with the following documents:

  • Proof of residency (can be any of the following):
    • copy of a RI Driver’s License, RI State ID
    • vehicle registration
    • voters registration
    • correspondence from another state agency with the current date
    • a current car insurance bill.
  • Valid ID: either an RI Driver’s License or RI State ID. 
  • A completed Practicioner Written Certification form filled out by an MD, DO, PA, or APRN who is licensed to practice in Rhode Island.
  • Minors patients must also fill out the Minor form included in the New Patient Application form. 
  • In addition to the proof of residency, caregivers must also submit a copy of a National Criminal Information Center (NCIC) background check from a local police department, the Office of the Attorney General, or by appointment with the Rhode Island State Police (401-222-1110)

A patient’s application fee costs $50. This fee can be waived if you can submit a written statement from your doctor that you qualify for hospice. Meanwhile, a caregiver’s application fee costs $100. However, applications fees for both patient and caregiver can be reduced to $25 upon the submission of any of the following:

  • Medicaid
  • Supplemental Security Income (SSI)
  • Social Security Disability Income (SSDI)
  • Veterans disability
  • Federal railroad disability 

The application fees to Rhode Island’s medical marijuana program may be inexpensive but growers also have to pay for plant tags that are required by the DBR. A set that comes with a tag for one mature plant and one seedling costs $25.
