What are the new CT cannabis laws in 2026?
The new CT cannabis laws in 2026 came from Public Act 26-8, effective October 1, 2026. Per DRS the statewide cannabis tax is now a flat 10.75%, and retailer THC drinks may hold up to 10 milligrams per container. Adults 21 or older still buy up to one ounce of cannabis or the equivalent in products a day.
These are the figures an adult 21 or older needs before a first trip to a cannabis store. Each one comes from the state statutes, the Department of Consumer Protection (DCP) or the Department of Revenue Services (DRS).
| Rule | The figure | Source |
|---|---|---|
| Minimum age to buy | 21 or older | CGS chapter 420h |
| Most you can buy in one day | One ounce of cannabis or the equivalent in products | CGS chapter 420h |
| Most you can carry on your person | 1.5 ounces of plant material | CGS chapter 420b |
| Most you can keep locked at home or in a locked glove box or trunk | Five ounces of plant material | CGS chapter 420b |
| Home grow for each adult 21 years of age and older | Three mature and three immature plants | CGS chapter 420b |
| Home grow for each household | Twelve plants at any given time | CGS chapter 420b |
| Statewide cannabis tax | 10.75% of gross receipts | Per DRS |
| State sales and use tax | 6.35% | Per DRS |
| Municipal cannabis tax | 3.0% of gross receipts | Per DRS |
| THC in one retailer infused beverage container | Up to 10 milligrams, starting October 1, 2026 | DCP 2026 legislative updates |
The current rules arrived in stages. According to DCP, possession of up to 1.5 oz by adults 21 and older became fully legal on July 1, 2021, and adult-use sales began on January 10, 2023 at licensed retailers. Public Act 26-8 took effect on October 1, 2026 and keeps the one ounce per day retail limit in place.
The law sets the limits. Which form fits your plans, whether flower, a vape, an edible or a drink, is a separate question. Call either of our stores, Derby or Hartford, at 860-420-BUDS (2837) for a recommendation, and tell us whether you smoke, vape, eat or drink your cannabis.
Proving your age before you buy
State law defines a consumer as an individual who is 21 or older, and the state's cannabis regulators confirm that registration is not required to buy, so you do not register with the state before you buy.
The statute also names the ID that counts. For a person who is 21 or older, a motor vehicle operator's license or an identity card with a full-face photograph is legal proof of age, and each licensee may accept it. DCP adds that any adult 21 or older with a valid government-issued photo ID may buy from licensed adult-use retailers regardless of state of residence.
For a licensee like us, selling to anyone under 21 is a class A misdemeanor, so bring that ID on every trip, even if you were in last week.
If you are visiting, our guide on whether out-of-state residents can buy weed in Connecticut goes further, and our walkthrough of a first visit to a cannabis store covers what happens after the ID check.
One change that took effect on October 1, 2026 concerns the personal data used to check your age. Under Section 66(g) of Public Act 26-8, no retailer may keep personal data obtained from a consumer for age verification for longer than 24 hours without the consumer's express written consent. DCP's notice on the 2026 legislative updates lists this rule with the other changes that started that day.
What you can buy in one day and carry home
A licensed retailer may not knowingly sell a consumer more than one ounce of cannabis, or the equivalent in products, in a single day. That cap counts the day, not the visit. DCP states that a consumer may not buy more than one ounce per day per customer regardless of the number of transactions, so a second trip the same day does not reset it.
Once you leave the store, the possession limits take over, and the law counts each form of cannabis its own way.
| Form | Equal to one ounce of flower | Equal to 1.5 ounces of flower, the carry limit |
|---|---|---|
| Flower | One ounce | 1.5 ounces |
| Concentrate | 5 grams | 7.5 grams |
| Edibles, drinks and other cannabis products | Products with up to 500 milligrams of THC | Products with up to 750 milligrams of THC |
For someone who buys edibles or drinks, that means the carry limit is measured in milligrams of THC, not in the weight of the package.
Locked storage raises the ceiling. A person 21 or older may keep five ounces of plant material in a locked container at their residence or in a locked glove box or trunk of their vehicle.
The possession figures above come from chapter 420b of the General Statutes, and our page on Connecticut cannabis possession limits goes deeper on carry and storage.
Where flower, vapes and edibles may be used
The form you use decides most of the answer. The state's rule is that you generally cannot smoke or vape cannabis anywhere you cannot smoke or vape tobacco, while edibles and drinks are treated differently in a rented home or a hotel.
| Place | Smoking or vaping cannabis | Edibles and drinks |
|---|---|---|
| A rented home | Your landlord may prohibit it | Your landlord generally may not prohibit it |
| A hotel or motel | Must be prohibited in any location | May not be prohibited in nonpublic areas |
| State parks, state beaches and state waters | Prohibited | Prohibited |
| A licensed cannabis store | Not allowed | Not allowed |
Restaurants fall under the state smoking law: smoking is prohibited in any restaurant and in any area of a retail establishment open to the public, and the law defines smoking to include cannabis. Towns can add rules of their own, because cities and towns may enact ordinances on whether and where cannabis can be consumed in public. Check your town's ordinance before you light up outside. CBIA, the state's business association, reported on June 29, 2021 that under the law legalizing marijuana, workplace smokers will no longer be able to smoke within 25 feet of a doorway, operable window, or air intake vent.
The store row applies to us too. On-site consumption of cannabis is not allowed at cannabis establishments at this time, so plan to use what you buy from us somewhere else. Our guide to where you can smoke weed in Connecticut covers more places.
Driving after cannabis
State law prohibits operating a motor vehicle while under the influence. The Department of Consumer Protection adds that cannabis should not be consumed before or during operation of a motor vehicle, whether it is smoked, vaped, eaten or sipped.
The state's courts may take judicial notice that ingesting cannabis can impair a person's ability to operate a motor vehicle, which means a court can accept that point in an impaired driving case without separate proof.
Refusing an evaluation carries its own cost. DCP says a driver who does not submit to an influence evaluation by a police officer trained as a DRE (DCP's term) may have their license suspended. Our guide to driving and cannabis in Connecticut goes further on impaired driving rules.
What adults 21 years of age and older may grow at home
Each adult 21 or older may grow three mature and three immature cannabis plants in their primary residence, and no household may have more than twelve plants growing at any given time. DCP adds three conditions: the plants are grown indoors, they are not visible from the street, and individuals under 21 cannot access them. Home grow has been open to adults 21 and older since July 1, 2023.
The details, including how the household cap works when several adults share a home, are in our Connecticut home grow guide.
The October 1, 2026 tax change
Before October 1, 2026, the statewide cannabis tax was based on milligrams of THC, and the rate depended on the form. The statute text still printed in CGS chapter 214c lists a separate cents-per-milligram rate of total THC for plant material, edible products and other cannabis, rates DRS now treats as superseded. Under that system, the same milligram of THC carried more tax in an edible than in flower.
Per DRS, since October 1, 2026 the statewide cannabis tax is a flat 10.75% of gross receipts from adult-use cannabis sales, whatever the form. The 6.35% state sales and use tax also applies to each of those sales, and the municipal cannabis tax is 3.0% of gross receipts.
DRS shows how the three taxes stack in a worked example on its cannabis tax page: a $22.00 sale carries $1.40 in sales tax, $0.66 in municipal tax and $2.37 in statewide cannabis tax, for a $26.43 total. Our explainer on Connecticut cannabis tax breaks the math down further.
Infused drinks and hemp THC products
Two dates decide who may sell a THC drink. Since October 1, 2024, only cannabis retail establishments and package stores with an endorsement to sell infused beverages may sell beverages containing THC. From October 1, 2026, infused beverage manufacturers may also sell infused beverages on-premises for off-site consumption. Starting October 1, 2026, a THC-infused drink sold by a retailer may contain up to 10 milligrams of THC per container.
Edibles carry two caps. Edible cannabis products are limited to 5 milligrams of THC per serving, and under DCP rules edibles can have no more than 100 milligrams of THC total in a multiple-serving package.
Two hemp-derived THC categories matter here. A moderate-THC hemp product has at least 0.5 milligrams and no more than 5 milligrams of THC per container, while high-THC hemp products and products with synthetic cannabinoids are considered cannabis, which brings them under the adult-use rules on this page.

Questions shoppers ask about Connecticut cannabis law
Can I buy cannabis in Connecticut if I live in another state?
Yes, if you are 21 or older with a valid government-issued photo ID, because there is no residency requirement for adult-use purchases. The same 1.5 oz possession limit applies to out-of-state residents as to state residents, and non-residents are charged the same state and local taxes as residents.
Does a delivery driver check my ID?
Yes. A delivery service must verify the identity of the person and the age of the consumer upon delivery, and the consumer must be 21 or older. It must also maintain an online interface that verifies the age of consumers ordering cannabis. Our guide to cannabis delivery in Connecticut explains how ordering works.
Can a town ban cannabis stores?
Yes. A municipality may by zoning or ordinance prohibit cannabis establishments, but no municipality shall prohibit delivery of cannabis to a consumer 21 or older by an authorized licensee. Cities and towns may also enact ordinances on whether and where cannabis can be consumed in public, so check your town's rules.
How much cannabis can an adult 21 or older buy in one day?
A retailer or hybrid retailer shall not knowingly sell a consumer more than one ounce of cannabis or the equivalent in products per day, and a consumer is 21 or older. DCP states the limit is per customer regardless of the number of transactions. Public Act 26-8 keeps the one ounce per day retail limit from October 1, 2026.
What is the Connecticut cannabis tax rate now?
Per DRS, the statewide cannabis tax has been a flat 10.75% of gross receipts from adult-use cannabis sales since October 1, 2026. The 6.35% state sales and use tax also applies to each of those sales, and the municipal cannabis tax is 3.0% of gross receipts. Before October 1, 2026, the statewide tax was based on milligrams of THC. Adult-use sales are for adults 21 and older.
Who can sell THC drinks in Connecticut?
Only cannabis retail establishments and package stores with an endorsement to sell infused beverages may sell beverages containing THC, a rule effective October 1, 2024. Beginning October 1, 2026, infused beverage manufacturers may also sell them on-premises for off-site consumption. A retailer's container may hold up to ten milligrams of THC, and buyers must be 21 or older.
