In Connecticut, cannabis is legal for adults 21+*, but there are limits regarding possession and the growing of marijuana plants. Just like with tobacco and alcohol, it is illegal for anyone under 21 to purchase, use, or possess cannabis. If you choose to use cannabis, purchase it from a licensed dispensary. All products from licensed sellers are tracked in a statewide seed-to-sale system and are tested so consumers can know exactly what they are buying. Illegally purchased marijuana may contain harmful contaminants and toxins.

DUI
Driving under the influence of cannabis is against the law. It is against the law for both drivers and passengers to use cannabis in a vehicle while it is operating.

Minors
It is illegal for adults to provide cannabis to minors. Connecticut’s “social host” law includes cannabis, which means that parents or other adults may commit a crime if they allow minors to use or possess cannabis on their property.
Employment
Some jobs may prohibit an employee from using cannabis, even when they are off the clock.
Smoking/Vaping in Public
In general, you aren’t able to smoke or vape cannabis anywhere you can’t smoke or vape tobacco. Cities and towns may enact their own ordinances about where cannabis can be consumed in public. At home, landlords may prohibit smoking and vaping. Cannabis use is prohibited in state parks, and on state beaches and waters.
Store it Locked!
Like many other substances, cannabis is harmful to children and pets. Make your home a safe environment where children cannot access cannabis products in any form. Safe storage can help lower the risk of accidental ingestion.
Be safe. Remember to:
- Keep cannabis in a secure and locked place. Cannabis products should be out of sight, and out of reach of children and pets to avoid accidental ingestion.
- Store cannabis products in their original containers and keep the label. Labels on cannabis products from licensed cannabis establishments will have important information, including how much THC is in the product.
- Consider using a safe or lockbox with a combination lock or keypad.
Make a list of cannabis products in your home. Knowing exactly what cannabis products you have in your home can help with medical treatment in case of accidental ingestion. - Clean up after using marijuana, including ground flower, crumbs, stems, lighters, and matches.

If a pet ingests cannabis, call Animal Poison Control.
