Connecticut legalized medical cannabis in 2012 under Public Act 12-55 and adult-use cannabis in 2021 through Senate Bill 1201 (An Act Concerning Responsible and Equitable Regulation of Adult-Use Cannabis), signed by Governor Lamont on June 22, 2021. Adult-use retail sales began January 10, 2023. The Department of Consumer Protection regulates all cannabis licensing, inspection, and enforcement through a dedicated cannabis division. The market has approached $500 million in annual revenue as of 2026, though growth has been tempered by price compression. No additional standalone dispensary facility licenses are being issued; existing dispensaries may convert to hybrid retail licenses serving both medical and adult-use consumers. The state's four original medical producers have maintained significant market dominance. Connecticut imposes a 6.35% sales tax plus a 3% municipal surcharge and THC-based excise taxes.
