As of July 1, 2021, adult-use ("recreational") cannabis is legal in Connecticut. SB1201 was signed by Gov. Ned Lamont on June 22, 2021 making Connecticut is the nineteenth state to legalize adult-use cannabis. The state also has a medical marijuana program for qualifying patients.

An equity commission is overseeing commercial licensing, giving priority to communities in poverty, and those harmed by the War on Drugs. Criminal records for possession under 4 oz, and prior to 2016, will be automatically expunged in 2023. Beginning July 1, 2022, larger and more recent offenses may be petitioned for expungement.

Retail sales are expected to begin May 2022, and will carry a base tax of 6.35%, scaling up for higher amounts of THC. The industry will be overseen by The Department of Consumer Protection.


Individuals may possess up to one and a half (1.5) ounces, with an additional five (5) ounces locked in a residence or car. One (1) ounce of cannabis flower is equivalent to five (5g) of concentrate.

Violators aged 18-20 will receive a fine, while minors will be referred to Youth Services. No one under twenty-one (21) may receive jail time for cannabis possession.

Qualified medical marijuana patients in Connecticut are allowed to possess up to three (3) ounces per month. Physicians may recommend lower or higher dosages that are subject to the Department of Consumer Protection’s (DCP) approval.

Purchasing Limits

Purchasing limits have not explicitly been set, but are expected to match possession amounts.

Flower potency is capped at thirty (30) % THC. Concentrates (excluding vape cartridges) may not exceed sixty (60) %. Edibles are capped at five  (5) mg THC per serving. Qualifying patients and caregivers shall be permitted to purchase cannabis of higher potency, varied dosage form, and in a larger per transaction or per day amount than are generally available for retail purchase, as determined by the commissioner.

Previously, qualified patients in Connecticut were required to designate one dispensary as their medicinal cannabis provider. As of October 1, 2021, qualifying patients are no longer required to designate a dispensary facility and may purchase from any licensed medical marijuana retailer.

Medical patients are allowed to buy up to two and a half (2.5) ounces of a patient's cannabis allotment at a time, unless a lower dose is assigned to the patient. Patients may purchase up to three (3) ounces per month, total.Where to Buy

Under Connecticut law, qualified patients can designate a caregiver with their physician’s approval. To qualify as a caregiver, a person must:

CT Caregiver Requirements:

  • Be eighteen (18) years old or older
  • Agree to undertake the responsibility of managing a patient
  • Have no prior controlled substance convictions
  • Not be the qualifying patient’s physician

In the event a qualifying patient lacks legal capacity or is a minor, you must be the patient’s parent, guardian or have other legal custody of the patient. Patients are allowed to have one caregiver at a time and can change their caregiver through the DCP once a year, if needed.

Transporting Marijuana

Patients and designated caregivers can carry their medical marijuana purchased from state-approved dispensaries as long as it does not exceed the monthly allowable limits.


Connecticut does not acknowledge medical marijuana cards from any other state at this time.


Medical patients can grow cannabis for personal use as of October 1, 2021. Patients are limited to three (3) mature plants and three (3) immature plants, with a maximum of twelve (12) per household.

Personal cultivation for recreational use will be legal July 1, 2023 with the same limits.


SB1201 lists delivery under the jurisdiction of the The Department of Consumer Protection, but no further details have yet emerged.
