Marijuana laws in Connecticut
Connecticut legalized adult-use cannabis in June Special Session Public Act 21-1, signed in 2021. Possession became legal on July 1, 2021, and licensed retail sales later followed. Medical marijuana has been legal since Public Act 12-55 in 2012. The adult-use law has been amended, including by Public Act 22-103 and Public Act 23-79.
Adults 21 and older may possess up to 1.5 ounces of cannabis plant material, plus up to 5 ounces in a locked container at home or in a locked glove box or trunk. Home-grown cannabis from a legal grow does not count against that personal possession limit. Adults may grow up to three mature and three immature plants at their primary residence, with no more than 12 plants per household, starting July 1, 2023. Medical patients could grow under the same plant counts beginning October 1, 2021.
Licensed retailers sell to adults 21 and older. Public consumption is not allowed. Employers may keep workplace policies. Marijuana remains illegal under federal law, apart from state-licensed medical marijuana, which moved to Schedule III in April 2026.

What the law says
Legal
- Any person twenty-one years of age or older may possess, use and otherwise consume cannabis, provided the amount of all such cannabis does not exceed such person's possession limit of (1) one and one-half ounces of cannabis plant material and five ounces of cannabis plant material in a locked container at such person's residence or a locked glove box or trunk of such person's motor vehicle
Quoted from Connecticut General Statutes §21a-279a.
How old do you have to be to use marijuana in Connecticut?
You have to be 21 to buy weed in Connecticut. Licensed adult-use retailers sell only to customers who show they are 21 or older. People 18 to 20 who have less than five ounces face fines, and people under 18 are steered to youth services or delinquency processes rather than a regular criminal arrest for those smaller amounts. Medical patients can access the medical program with a physician certification.
How much marijuana can you have in Connecticut?
Adults 21 and older in Connecticut can have up to 1.5 ounces of cannabis plant material on them, and up to 5 ounces in a locked container at home or in a locked glove box or trunk. At home, cannabis from your own legal plants does not count against that possession limit. In a car, amounts above 1.5 ounces need to be locked in the glove box or trunk. One and a half ounces of plant material is treated as equal to 7.5 grams of concentrate or other products with up to 750 milligrams of THC.
Where can you buy marijuana in Connecticut?
You can buy weed in Connecticut at licensed retailers, hybrid retailers and other licensed cannabis establishments, including some delivery services. Buyers must be 21 or older and show a valid ID. Medical patients buy through the medical program rather than as ordinary adult-use customers. Unlicensed sellers are not a legal source.
Can you grow marijuana at home in Connecticut?
Yes. Adults 21 and older in Connecticut can grow up to three mature and three immature cannabis plants at their primary residence, with a household cap of 12 plants. Those adult home-grow rights started July 1, 2023. Medical patients could grow under the same plant counts starting October 1, 2021. Plants have to be secured from other people. Selling homegrown cannabis without a license is illegal.
Where can you use marijuana in Connecticut?

How do you get a medical marijuana card in Connecticut?
To get a medical marijuana card in Connecticut, you need a certification from a licensed provider that you have a qualifying condition, and then you register with the state's medical marijuana program. Medical patients have been able to grow at home since October 1, 2021, under the same 3 mature / 3 immature plant rules, and they can buy at medical dispensaries.
Can visitors buy or use marijuana in Connecticut?
Yes. Out-of-state visitors can buy marijuana in Connecticut if they are 21 or older. The adult-use possession law does not require Connecticut residency to possess or purchase within the limits. Visitors follow the same 1.5-ounce and locked 5-ounce rules and the same ban on public use. Taking cannabis out of Connecticut isn't protected by state law and remains illegal under federal law.
What are the rules on driving and marijuana in Connecticut?
No, you can't drive high in Connecticut. The adult-use law does not allow driving while impaired by cannabis, and opened or unlocked cannabis in a car has to follow the locked glove-box or trunk rules if you are over the 1.5-ounce on-person limit.
Can an employer in Connecticut fire you for using marijuana?
Yes, you can get fired for using marijuana in Connecticut, even legally off the job. The legalization law does not require employers to accommodate cannabis use, and employers may keep drug-free workplace policies, including testing and discipline for a positive result or for impairment at work.
What are the penalties for breaking marijuana laws in Connecticut?
In Connecticut, adults 21 and older who go over the possession limit but stay under five ounces of plant material, or eight ounces locked at home, face a $100 fine the first time and $250 after that. At or above five ounces, or eight ounces locked at home, the first offense is a $500 fine and a later offense is a class C misdemeanor. People 18 to 20 face separate civil fines for smaller amounts. Selling without a license remains a crime.
Are CBD, hemp and delta-8 products legal in Connecticut?
CBD from hemp can be sold in Connecticut, but intoxicating hemp-derived THC products are regulated separately from ordinary hemp. High-THC hemp products, including many delta-8 and THCA items, are not treated as unregulated convenience-store products; the state's cannabis market is the licensed path for intoxicating cannabis. Separately, a stricter federal hemp definition, with a total-THC standard that counts THCA and a 0.4 mg-per-container cap, takes effect December 11, 2026.
Does federal law still apply in Connecticut?
Yes. Federal law still applies in Connecticut. Marijuana remains a Schedule I controlled substance under federal law, with one exception: since April 28, 2026, marijuana covered by a state medical marijuana license and FDA-approved marijuana products are in Schedule III. A broader federal rescheduling proceeding was stayed on September 29, 2026, and has no decision date. State law does not change federal rules on federal land, on carrying marijuana across state lines, or on federally required drug testing, such as for DOT-regulated jobs.
Has the law in Connecticut changed recently, or is it about to?
Connecticut's adult-use framework is still built on Public Act 21-1 (2021), with later amendments in Public Act 22-103 and Public Act 23-79. Adult home grow for non-patients began July 1, 2023. No broad 2026 rewrite of the possession limits was identified. At the federal level, state-licensed medical marijuana moved to Schedule III on April 28, 2026. New federal hemp limits begin November 12 and December 11, 2026.
