Connecticut Marijuana Compliance
Connecticut marijuana laws legalized both medical and recreational marijuana. Connecticut marijuana compliance guidelines must be followed to remain legal. For example, marijuana is legal for adults 21 and older in Connecticut, including visitors from other states, but there are limits on how much marijuana people can have and where they can use it. Medical marijuana patients have their own rules and need to be certified by an approved healthcare provider.
Connecticut employers can ban marijuana use and being impaired at work. In most cases, an employer can't take action against someone just for a positive marijuana test unless an exception applies. One example is a written marijuana policy that was shared with employees. Some employers and jobs are exempt from these rules, and registered medical marijuana patients have their own protections.
State and federal marijuana laws differ. Connecticut permits medical marijuana and adult recreational use under state law. Federally, recreational marijuana remains a Schedule I controlled substance. An April 2026 federal rule moved certain medical marijuana products, including those covered by qualifying state medical licenses, to Schedule III, but federal requirements still apply. Connecticut residents and employers should understand both sets of rules.

Connecticut allows adult-use cannabis within legal limits. Certain past cannabis convictions qualify for automatic erasure or erasure by petition, depending on the offense and conviction date.

They may also grow up to three mature and three immature plants, with a maximum of 12 plants per household.
