Marijuana laws in Rhode Island
Rhode Island enacted the Rhode Island Cannabis Act in 2022 (P.L. 2022, chapters 31 and 32), effective May 25, 2022. Medical marijuana has been legal since the Edward O. Hawkins and Thomas C. Slater Medical Marijuana Act. Adult-use retail sales followed under the Cannabis Control Commission.
Adults 21 and older may possess, use, buy from a licensed retailer, or process one ounce or less of cannabis, or the equivalent in concentrate. They may cultivate up to three mature plants and three immature plants per dwelling unit, no matter how many people live there, if security rules are followed. At a primary residence, each resident may possess up to 10 ounces, plus lawful plants. Adults may also give away up to one ounce to another adult 21 or older if nothing is paid and the transfer is not advertised.
Smoking or vaporizing cannabis is not allowed in a public place that bans tobacco smoking or vaporizing, or in any place that separately bans cannabis. Possessing one ounce or less without adult-use authorization can still be a civil offense for some people under older title 21 rules, but adults 21 and older acting within the Cannabis Act are protected.
Marijuana remains illegal under federal law, apart from state-licensed medical marijuana, which moved to Schedule III in April 2026.

How old do you have to be to use marijuana in Rhode Island?
You have to be 21 to buy weed in Rhode Island. The Cannabis Act protects adults 21 and older who buy from a licensed cannabis retailer, possess up to one ounce, or grow within the plant limits. People under 21 are not covered by those adult-use protections. Medical patients can still use the medical program under chapter 21-28.6.
How much marijuana can you have in Rhode Island?
Adults 21 and older in Rhode Island can have up to one ounce of cannabis, or the equivalent in concentrate, on them. At home, each resident may possess up to 10 ounces, plus live plants that are lawfully grown at that dwelling. In a car, stay within the one-ounce on-person limit. You may give up to one ounce to another adult 21 or older if nothing is paid and the gift is not advertised.
Where can you buy marijuana in Rhode Island?
You can buy weed in Rhode Island at licensed cannabis retailers if you are 21 or older and show valid ID. Medical patients can also buy through the medical marijuana program. Buying from an unlicensed seller is not legal. The Cannabis Control Commission licenses adult-use businesses under the Rhode Island Cannabis Act.
Can you grow marijuana at home in Rhode Island?
Yes. Adults 21 and older in Rhode Island can grow up to three mature cannabis plants and three immature plants per dwelling unit for personal use, no matter how many people live there, as long as commission security rules are met. Those plants do not count against the 10-ounce at-home possession cap. Unlicensed growing above those limits is not protected.
Where can you use marijuana in Rhode Island?
You can smoke weed in Rhode Island mainly on private property. The law does not authorize smoking or vaporizing cannabis in any public place, and it is prohibited in any public place that bans tobacco smoking or vaporizing, and in any place that separately bans cannabis by rule, regulation or local ordinance. That includes school buses, school grounds, correctional facilities and licensed drug-treatment facilities.
How do you get a medical marijuana card in Rhode Island?
To get a medical marijuana card in Rhode Island, you apply under the Edward O. Hawkins and Thomas C. Slater Medical Marijuana Act, chapter 21-28.6, through the state medical program. A card is useful for patients who want medical products or who are under 21. Adults 21 and older can also buy at licensed adult-use retailers without a medical card.
Can visitors buy or use marijuana in Rhode Island?
Yes. Out-of-state visitors can buy marijuana in Rhode Island if they are 21 or older. The adult-use statute has no residency requirement for purchasing from a licensed retailer. Visitors follow the same one-ounce, public-use and home-grow rules as residents. Taking cannabis out of Rhode Island across state lines remains illegal under federal law.
What are the rules on driving and marijuana in Rhode Island?
No, you can't drive high in Rhode Island. The Cannabis Act does not allow anyone to operate, navigate or be in actual physical control of a motor vehicle while under the influence of cannabis. A legal purchase or a medical card is not a defense to impaired driving.
Can an employer in Rhode Island fire you for using marijuana?
Yes, you can get fired for smoking weed in Rhode Island, especially if the job is hazardous, dangerous or essential to public welfare and safety. For those jobs, an employer may ban cannabis use within 24 hours before a shift. The adult-use law does not require other employers to allow on-the-job use or impairment, and federally required testing still applies.
What are the penalties for breaking marijuana laws in Rhode Island?
Adults 21 and older acting within the Cannabis Act's ounce, plant and home-storage limits are protected from state arrest and prosecution for those acts. Going over the limits, selling without a license, or giving cannabis to someone under 21 can bring criminal charges. Older title 21 rules still treat some unauthorized possession of one ounce or less as a civil offense with a $150 penalty and forfeiture.
Are CBD, hemp and delta-8 products legal in Rhode Island?
Hemp and hemp-derived CBD that meet the legal hemp definition are regulated separately from licensed cannabis in Rhode Island. Intoxicating products sold as delta-8 or THCA may be treated as cannabis if they fall outside that definition. Licensed adult-use and medical cannabis must come from licensed establishments. Separately, a stricter federal hemp definition, with a total-THC standard that counts THCA and a 0.4 mg-per-container cap, takes effect December 11, 2026.
Does federal law still apply in Rhode Island?
Yes. Federal law still applies in Rhode Island. Marijuana remains a Schedule I controlled substance under federal law, with one exception: since April 28, 2026, marijuana covered by a state medical marijuana license and FDA-approved marijuana products are in Schedule III. A broader federal rescheduling proceeding was stayed on September 29, 2026, and has no decision date. State law does not change federal rules on federal land, on carrying marijuana across state lines, or on federally required drug testing, such as for DOT-regulated jobs.
Has the law in Rhode Island changed recently, or is it about to?
Rhode Island's adult-use law has been in effect since May 25, 2022, when P.L. 2022, chapters 31 and 32, took effect. Possession, purchase and home-grow limits remain those in §21-28.11-22. No repeal of adult use is pending. New federal hemp limits begin November 12 and December 11, 2026.
