Is Marijuana Legal in Connecticut?

Connecticut has legalized the use of marijuana for both medical and recreational purposes. The legalization of medical marijuana came first, with the passage of HB 5389 in 2012. Recreational marijuana was legalized in 2021 following the passage of SB 1201. Medical marijuana patients or their caregivers are allowed to purchase 5 ounces. of marijuana within a 30-day period from licensed dispensaries. Medical marijuana patients are allowed to grow three immature and three mature marijuana plants in their homes, so long as they ensure that the plants are kept away from persons other than the patient and caregiver. Qualifying patients and their caregivers are permitted to grow no more than 12 marijuana plants within the confines of their homes.

Beginning in July 2021, SB 1201 allowed adults in Connecticut to possess no more than 1.5 ounces of marijuana and to keep up to 5 ounces in a secure container such as a glove compartment or vehicle trunk. From July 1, 2023, adult residents of Connecticut can grow up to six cannabis plants, of which no more than three may be mature. Households with more than one adult can grow up to 12 plants.

Connecticut Marijuana Laws in 2024

In May 2022, HB 5329 was signed by Connecticut Governor Ned Lamont. Section 2 of the Bill includes a provision prohibiting Connecticut residents from gifting cannabis unless the recipients are family members or friends. Even when cannabis gifting takes place in a familial or friendly relationship, there must be no money or favors exchanged in return for the cannabis. Cannabis gifting involves shops selling gifts or trivia items to individuals and giving them cannabis as ostensible souvenirs. It may also take the form of supposedly charitable donations or entry fees to events for which cannabis is given in return. This practice typically occurs in jurisdictions where cannabis is legal for medical but not yet for recreational purposes. Violators of this provision will pay a fine of $1,000 for each offense and face an administrative hearing held by the Commissioner of Revenue Services. This provision legally took effect on July 1, 2022.

HB 5329 also contains a provision mandating Connecticut dispensaries intending to obtain hybrid-retail licenses to obtain approval for their workforce development plans from the Social Equity Council. Workforce development plans entail providing training and employment to individuals from areas of Connecticut that have been disproportionately affected by the enforcement of rescinded laws on cannabis. Section 8 of HB 5329 took effect in October 2022. It stipulated the kinds of advertising that cannabis establishments were allowed to use. Section 9 of HB 5329 gave municipalities in Connecticut the authority to pass ordinances prohibiting cannabis establishments within their jurisdictions and regulating the location and operating hours of cannabis establishments.

A 2023 change in Connecticut’s cannabis laws permits home cannabis cultivation for adults aged 21 or older. This change follows from a 2021 legislation that reduced the penalties for those growing cannabis at home for recreational use. Previously, Connecticut only allowed qualified medical patients to grow marijuana at home.

From December 1, 2023 Connecticut also raised the limit of the amount of recreational marijuana that adults can buy in the state’s dispensaries. An eligible adult in Connecticut can now purchase up to half an ounce of raw cannabis flower, or its equivalent, in a single transaction.
