Connecticut currently allows medical marijuana use and has decriminalized first-time small possession offenses. The reform movement began in 2011 when Governor Daniel Malloy passed the decriminalization measure. Medical cannabis use was signed into law the following year by the governor, with dispensaries finally opening in 2014.

Governor’s Bill No. 16 was introduced by state lawmakers in February of 2020. If passed, the bill would establish a legalized adult-use market in Connecticut. Gov. Ned Lamont has called for legalization in the state, and is in full support of creating a regulated system. We will update this space as the bill advances, though cannabis for adult use is currently illegal at this time. Here are the current laws you need to know:


Qualified medical marijuana patients in Connecticut are allowed to possess up to 2.5 ounces per month. Your physician could recommend lower dosages that are subject to the Department of Consumer Protection’s (DCP) approval.

Purchasing Limits

Qualified patients in Connecticut designate one dispensary as their medicinal cannabis provider. The patient is allowed to buy up to 2.5 ounces of cannabis unless a lower dose is assigned to the patient.
