On June 22, 2021, Governor Ned Scott signed Senate Bill 1201, An Act Concerning Responsible and Equitable Regulation of Adult-Use Cannabis, to legalize the taxation and regulation of adult-use cannabis in Connecticut. It was the fourth recreational bill to pass via the legislature in 2021. Possession and consumption became legal July 1, 2021, and the recreational sales are expected to begin in 2022.

Connecticut legalized medical marijuana in 2012, under House Bill No. 5389, An Act Concerning the Palliative Use of Marijuana. The act created a patient registry system, and implemented regulations surrounding possession, use and sales. Medical marijuana dispensary storefronts first opened in 2014.
