Is Weed Legal in Connecticut?

Connecticut marijuana laws have a complex history, dating back to the production of industrial hemp. Following World War II, hemp production in Connecticut fell drastically. Anti-drug campaigns and the eventual passage of Republican President Richard Nixon’s Controlled Substances Act made cannabis illegal in Connecticut and the rest of the US. Over the decades, public and legislative opinions on cannabis shifted.


Democratic Gov. Dannel Malloy signed a General Assembly-drafted measure in June 2011 to decriminalize the possession of up to 0.5 ounce (14.2 grams) of cannabis. Offenders pay increasing fines for subsequent offenses.


In May 2012, the Connecticut General Assembly of Representatives passed HB 5389, which legalized medical marijuana in Connecticut. This bill added Chapter 420f, “An Act Concerning the Palliative Use of Marijuana,” to the Connecticut General Statutes.


HB 5389 revised the Regulations of Connecticut State Agencies to make the Connecticut Department of Consumer Protection (DCP) responsible for the regulation and governance of medical cannabis use.


In Connecticut, recreational weed has seen an uphill battle and the state has yet to legalize marijuana for the general population. However, Connecticut decriminalized weed in 2011 under Governor Dannel Molloy. Because of the marijuana laws in Connecticut, recreational dispensaries are still outlawed. 

Where is it safe to purchase & consume?

Registered patients and primary caregivers may purchase medical cannabis from licensed pharmacists employed by licensed dispensary facilities under Connecticut marijuana laws. Individuals may not purchase an amount of cannabis that would cause them to exceed possession limits of 2.5 ounces (56.7 grams) per month. Patients designate a licensed dispensary at the time of their application.


Licensed dispensary facilities are located throughout Connecticut. Registered patients may purchase flower, edibles, concentrates, topicals, and tinctures, as well as consumption accessories from dispensary facilities. Patients are responsible for state and local sales taxes at the time of purchase.


At this time, medical marijuana delivery services are not available in Connecticut.


Registered patients in Connecticut may ingest their cannabis medicine only in private spaces.


Registered patients may consume flower, edibles, concentrates, topicals, and tinctures, as well as possess and use consumption accessories. State law prohibits the manufacturing of edibles.


Connecticut law prohibits medical cannabis use on public transportation, in the workplace, on school or university campuses, in public places, or in the presence of anyone younger than 18. The law also prohibits the use of medical marijuana that would endanger the health or well-being of another person.

Possessing Cannabis

Patients may possess up to 2.5 ounces (56.7 grams) per month unless their physician indicates a lesser amount is appropriate. State law prohibits the gifting or exchange of medical cannabis between any entities except between a patient and primary caregiver.


Landlords cannot refuse to rent to or take action against an individual based solely on his or her status as a registered patient. Schools, likewise, cannot refuse enrollment based solely on a person’s status as a registered patient. Employers cannot refuse to hire or choose to fire registered patients, though they may prohibit the use of cannabis during work hours.


Home Cultivation

Home cultivation is prohibited in Connecticut. Registered patients and primary caregivers may obtain medical cannabis only from licensed dispensaries.

Patient Qualifications

A patient may only register for medical marijuana if he or she is a Connecticut resident being treated by a licensed physician for a qualifying medical condition.


Minor patients must meet with two physicians: one, the patient’s primary doctor and the other, a board-certified specialist in the field of treatment for the patient’s qualifying condition. One of these physicians will submit a certification to the DCP, while the other must provide the parent or guardian caregiver with a letter confirming medical cannabis use being in the patient’s best interest.


State law does not require government or private insurance companies to cover medical marijuana use.

Medical Marijuana Registry Process

  1. Receive a written certification from a licensed physician that states the patient suffers from a qualifying debilitating condition. This certification is submitted to the DCP by the patient’s physician.
  2. Create an account with the Connecticut Department of Administrative Services (DAS) Business Network to access the online certification system and follow all prompts.
  3. Select the “I am a Patient” option, fill in all identification information, and upload proof of identity, proof of residency, and a color photograph.
  4. Pay a $100 application fee. The registration expires one year after the physician’s certification date.

Caregiver qualifications

If a patient’s doctor certifies the need for a primary caregiver, the patient may appoint and register one person to assist in accessing and administering medical cannabis.


The caregiver must be at least 18 years old and cannot be the patient’s physician, or be convicted of a controlled substance violation. Caregivers can only be responsible for one patient at a time unless there is a parent, guardian, or sibling relationship with each patient.


Parents or legal guardians are required to serve as the primary caregivers for patients younger than 18.

Caregiver Registration Process

Patients must include their caregiver’s information when applying for Connecticut’s Medical Marijuana Program.

  1. Receive written certification from aphysician that indicates the need for a primary caregiver.
  2. Receive an email sign-up link from the registered patient’s application process to complete the caregiver portion of the application.
  3. Create an account with the DAS Business Network to access the online certification system and follow all prompts.
  4. Select the “I am a Caregiver” option, fill in identification information, and upload proof of identity, proof of residency, and a color photo.
  5. Pay a $25 application fee. The registration expires one year after the physician’s certification date.

Information for Providers

Physicians and nurse practitioners licensed to practice medicine in Connecticut may provide qualifying individuals with a written certification to use medical cannabis. Physicians must register with the Connecticut Prescription Monitoring and Reporting System (CPMRS) to gain a complete overview of a patient’s controlled substance use.


To certify patients for medical cannabis use, physicians must state on the DCP’s online form that a patient has been diagnosed with a disease that qualifies them for medical marijuana and that, based on reasonable medical assessment, the potential benefits of cannabis use outweigh the risks.


Physicians must create an account with the DAS Business Network to access the DCP’s online certification process.


Connecticut state law only allows qualified patients who are residents of Connecticut to possess and purchase cannabis at licensed dispensaries. No reciprocity is offered to out-of-state residents.


Lab Testing

Licensed producers must have laboratory employees on staff to randomly test cannabis product batches for quality assurance. Laboratories must test samples for:

  • Heavy metals
  • Microbiological contaminants
  • Mycotoxins
  • Pesticides

Producers must have lab results for each medical marijuana batch purchased by a dispensary facility and provide them onrequest to qualified patients, caregivers, and physicians with certified patients.


Licensing for Growers, Manufacturers, Processors, and Retailers

Only licensed pharmacists may apply for and obtain a cannabis dispensary license from the DCP. Entities seeking to become licensed marijuana dispensary facilities must prepare all necessary documents, responses, and appendices as required by the DCP. The application package and nonrefundable $1,000 application fee is due no later than the date referenced in each application period.


Following the application submission, the DCP will evaluate and rank all applications,  then award licenses to those with the highest scores. If selected, licensed dispensaries must pay a $5,000 registration fee. Licenses expire annually and require a renewal application and $5,000 fee.


Each application period, called Request for Application (RFA), the DCP reserves the right to approve a limited number of licenses within Connecticut. For example, the DCP opened the RFA for three and 10 licenses for dispensaries in 2018. It awarded nine.


Connecticut law allows for only three to 10 licensed producers at a time. Only producers licensed by the DCP are authorized to cultivate marijuana for medical use. Entities seeking to apply as licensed producers must provide evidence of their financial capacity to build and operate a secure indoor growing facility. The application fee for medical cannabis producers is $25,000. If approved, the licensed producer must pay a $75,000 registration fee. Licenses expire annually and require a renewal application and a $75,000 fee.
