Rhode Island RIGL §21-28.11 (Cannabis Act, 2022) allows adults 21+ to grow up to 6 plants at home (3 mature). Providence County municipalities follow state limits. Plants must be in secure, enclosed space not visible from public view.
Under the Rhode Island Cannabis Act (RIGL §21-28.11-10), adults 21 and over may cultivate up to 6 cannabis plants at their primary residence, of which no more than 3 may be mature (flowering). A household with multiple adults is still capped at 12 plants maximum (6 mature). Plants must be grown in an indoor space or enclosed outdoor area not visible from any public place or from another private property without the use of binoculars or aircraft. The cultivation area must be secured with a lock. Medical marijuana patients registered with the RI Department of Business Regulation Office of Cannabis Regulation retain separate limits (up to 12 plants per patient). Providence, Cranston, Pawtucket, and Woonsocket have not added stricter plant caps. Landlords may prohibit cultivation in leased premises under RIGL §21-28.11-27. Smoking in public remains prohibited and punishable by $150 civil fine. Cultivation for sale without a retail license is a criminal offense.
Exceeding 6/3 plant limit: civil penalty up to $150 per excess plant for first offense under RIGL §21-28.11-29. Visible or unsecured cultivation: same civil range. Cultivation for unlicensed sale: criminal charges under RIGL §21-28.4. Selling to minors: felony.
