Cannabis in Connecticut

Yes: adults 21 and older can legally buy, carry and grow cannabis in Connecticut. Possession became legal on July 1, 2021 under Public Act 21-1, and licensed stores began adult-use sales on January 10, 2023. The Department of Consumer Protection (DCP) licenses retailers, hybrid retailers (former medical dispensaries that also serve adults), micro-cultivators and delivery services, and it publishes a map of every store licensed to sell.

Adults may carry up to 1.5 ounces and keep up to 5 ounces at home or locked in a car's trunk or glove box. Since July 30, 2025, a store may sell one customer up to one ounce of flower, or the product equivalent, per day, no matter how many transactions that takes. Adults can grow three mature and three immature plants indoors at their primary residence, with a cap of 12 plants per household, out of view from the street and out of reach of anyone under 21. Smoking and vaping are banned wherever tobacco smoking is banned, and use is prohibited in state parks, on state beaches and on state waters; towns can add their own rules. Retailers and hybrid retailers may deliver to adult customers themselves or through a licensed delivery service.

Two 2026 laws change the details. Public Act 26-8 (HB 5350), signed by Governor Ned Lamont on May 20, 2026, rewrites cannabis, hemp and THC-beverage rules and opens the medical program to qualifying out-of-state patients. Together with Public Act 26-100, it removes the THC cap on concentrates from October 1, 2026, while flower stays capped at 35% THC. The THC-based tax ends on that same date: the Department of Revenue Services now charges a flat 10.75% cannabis tax, on top of the 6.35% sales tax and the 3% municipal cannabis tax. On a $22 chocolate bar, that adds up to $26.43 at the register.

Before you buy, look the store up in DCP's eLicense search or on its map of licensed retailers. This page is general information, not legal advice.
