Yes, marijuana is legal in Connecticut for both medical and recreational use. Adults aged 21 and over can legally possess and consume marijuana. The state also operates a medical marijuana program for patients with qualifying conditions, providing them with legal access to cannabis for therapeutic purposes.
In Connecticut, adults 21 and over can legally possess up to 1.5 ounces of marijuana on their person and up to 5 ounces in a locked container in their home or vehicle's trunk or glove compartment. Medical marijuana patients are allowed a 5-ounce supply every 30 days, strictly from state-approved dispensaries.
Adults in Connecticut are permitted to cultivate cannabis at home for personal use. Each adult may grow up to 6 plants — with no more than 3 mature (flowering) and 3 immature plants at a time. In households with multiple adults, the total cultivation limit is 12 plants (e.g., two adults could grow 6 mature and 6 immature plants combined). All plants must be grown indoors at the person’s primary residence, must not be visible from the street, and must be kept where individuals under 21 cannot access them. Adult-use cannabis may be purchased from licensed retailers or hybrid retailers, while registered patients may purchase medical marijuana from dispensary facilities or hybrid retailers.
Penalties for marijuana-related offenses vary by the nature and severity of the violation. Possession of more than the legal amount can lead to fines and imprisonment. Illegal cultivation or intent to sell marijuana can result in even harsher penalties, including longer jail terms and higher fines, especially if done near restricted areas like schools.
In Connecticut, licensed physicians, physician assistants, and advanced practice registered nurses may certify qualifying patients for medical marijuana. Beginning in 2026, eligible dispensary pharmacists may also issue certain temporary 90-day certifications or extensions for adults. Regular certifications may be issued for 6 months, 1 year, 18 months, or 2 years.
Cannabis generally cannot be smoked or vaped anywhere tobacco smoking or vaping is prohibited. Connecticut municipalities may also regulate whether and where cannabis may be consumed in public, and cannabis use is prohibited in state parks, beaches, and waters.
Only individuals who are 21 years or older can visit recreational dispensaries. Medical dispensaries require patients to have a valid medical marijuana card issued by the state.
Possession above Connecticut’s legal cannabis limits is subject to penalties that vary by the amount and prior offenses, but it does not automatically become a felony. Unauthorized manufacture, distribution, sale, or possession with intent to sell is separately subject to criminal penalties.
Penalties depend on the amount, the person’s age, and prior offenses. Possession above the legal limit may result in fines or, for certain subsequent offenses, criminal penalties. Separate offenses and enhanced penalties may apply to unauthorized cannabis sales or distribution involving minors.
Adults 21 and older may legally possess up to 1.5 ounces of cannabis on their person, so possession of less than half an ounce is not subject to a $150 possession fine. Possessing more than the legal limit but less than 5 ounces generally carries a $100 fine for a first offense and $250 for a subsequent offense.
Yes, edibles are legal in Connecticut and can be purchased from licensed dispensaries.
Yes, hemp-derived CBD products may be legally sold in Connecticut when they comply with the state requirements applicable to their THC content and product type. Connecticut regulates moderate- and high-THC hemp products separately, and the 0.3% dry-weight limit is not the sole standard for all finished CBD products.
