Is weed legal in Maine?
Yes. Both medical and adult-use, or recreational, cannabis is legal in Maine for adults 21 and older.
On Nov. 2, 1999, Maine Medical Marijuana for Specific Illnesses, or Ballot Question 2, passed with 61% of voters in favor. It legalized medical cannabis for patients suffering from serious health conditions.
In 2009 voters passed the Maine Medical Marijuana Act , which expanded the state’s existing program and decriminalized cannabis possession of up to 2.5 ounces (71 grams). It officially established the Maine Medical Use of Marijuana Program (MMMP). The act created a system of nonprofit dispensaries and cultivators, giving patients and caregivers better access to treatments.
On Nov. 8, 2016, Maine voters passed An Act to Legalize Marijuana , allowing adults 21 and older to possess, consume, and cultivate marijuana for personal use. Since voters approved the original legislation in November 2016, the legislature made a number of changes and compromises and had to overcome vetoes to pass an amended law, LD 1719 . Among the changes was reducing the number of marijuana plants a recreational consumer can grow at home from six to three. The Legislature also postponed consideration of cannabis social clubs until 2023, leaving private property as the only place where recreational cannabis can be consumed.
The revised law established rules for sales of recreational weed and gave Mainers priority for commercial licenses. The provision giving priority to in-state businesses was struck down in 2020 after an out-of-state business brought a lawsuit. That was just one of the wrinkles that kept the state from awarding any recreational retail licenses until September 2020.

Only medical patients can buy medical marijuana in Maine. Individuals who have received a patient certification from a medical professional may legally access medical marijuana from a caregiver or dispensary. Cards are available to Maine residents only.
Patients visiting Maine from another state may be able to purchase medical marijuana from a registered caregiver or dispensary if they have valid patient identification credentials (like a registry or patient identification card) and their state of residence allows them to use their state-issued credential to purchase medical marijuana in Maine.
How many dispensaries does Maine currently have in operation?
Maine has eight dispensaries. A list is available online here: https://www.maine.gov/dafs/omp/medical-use/dispensaries
Please note: dispensaries are not to be confused with caregivers. A caregiver may operate one retail store to sell their products.

Until recently, dispensaries were required to by nonprofit entities and there was only one per Maine Department of Health and Human Services Public Health District. At present, the most notable difference is that dispensaries can grow an unlimited number of marijuana plants.
How much does it cost to obtain a patient certification?
The cost for a patient certification depends on the medical provider conducting the examination and issuing the certification.
The Maine Medical Use of Marijuana Program provides patient cards to registered providers. In order to ensure patient access to the program, the State of Maine has never charged medical providers for the cards they provide to qualifying patients.
If an individual is interested in obtaining a medical card, they may wish to have those discussions with their primary care physician or other trusted medical provider. They may find in doing so that they are able to obtain a card at little to no cost to them.
Are temporary/digital/electronic patient certifications valid?
No. Temporary and/or digital medical marijuana patient cards or certifications are not an acceptable form of identification for the purposes of obtaining marijuana for medical use in Maine.
To be a qualifying patient in Maine’s program, among other things, an individual must possess “a valid written certification. ” A written certification is only valid if it is “a document on tamper-resistant paper signed by a medical provider. “. These requirements are written into law and aim to preserve the integrity of the medical marijuana program by reducing the possibility of altering and tampering with valid medical certifications.
The Office of Marijuana Policy provides medical providers with tamper-resistant patient certification paper at no cost.
Where can I find statistical information on the medical program?
You may be interested in reviewing the annual reports or open data of the Maine Medical Use of Marijuana Program.
What do I need to apply for or renew a registry identification card (caregiver, caregiver assistant, dispensary employee, etc.)?
Download, complete, and submit the appropriate medical use application. Among other things, you will need to provide a copy of your Maine-issued driver’s license or identification card as proof of residency.
Please review all materials for completeness prior to submission to ensure their timely consideration and processing.
In accordance with Governor Mills’ civil emergency declaration and corresponding executive order, the Office of Marijuana Policy will accept Maine driver’s licenses or identification cards that expired on or after March 15, 2020 as valid for the purposes of registry identification card applications and renewals. The executive order issued by Governor Mills deems these forms of identification extended until 30 days after the termination of the ongoing civil emergency.
How long does it take to get my caregiver card?

The average time frame to approve an application is currently one month.
