Adult-Use Cannabis in Maine
Recreational cannabis is legal in Maine for adults 21 years of age and older. On November 8, 2016, voters narrowly approved Question 1 with 50.26% of the vote — a margin of just 3,995 votes, the closest cannabis legalization vote in American history. The first licensed recreational sale did not occur until October 9, 2020, nearly four years later, due to repeated vetoes by Governor Paul LePage.
Maine's recreational cannabis law is codified as Title 28-B of the Maine Revised Statutes. The program is administered by the Office of Cannabis Policy (OCP) within the Department of Administrative and Financial Services (DAFS).
Title 28-B governs the adult use of cannabis in the State of Maine, including the cultivation, manufacture, distribution, testing, and sale of adult use cannabis and adult use cannabis products.

Who Can Buy Recreational Cannabis
To legally purchase recreational cannabis in Maine, you must:
- Be at least 21 years old
- Present a valid, government-issued photo ID (driver's license, passport, military ID, or state ID)
- Purchase only from an OCP-licensed retail store
There is no residency requirement. Out-of-state visitors can buy and consume cannabis under the same rules as Maine residents. For visitor-specific tips, see our Out-of-State Visitors guide.
Purchase & Possession Limits
Maine's possession limits were updated in 2023 by P.L. 2023, c. 220 and c. 396:
| Category | Recreational (21+) | Medical (certified patient) |
|---|---|---|
| Flower possession | 2.5 ounces total | 8 pounds at home |
| Concentrates | 10 grams (within 2.5 oz total) | Included in 8 lb limit |
| Home plants (per person) | 6 mature, 12 immature, unlimited seedlings | 6 mature, 12 immature, unlimited seedlings |
| Purchase per transaction | 2.5 ounces | No daily/monthly caps |
Recreational limits updated by P.L. 2023, c. 220 and c. 396. Medical patients enjoy significantly higher limits.
The concentrate limit increased from 5 grams to 10 grams in 2023 — many online sources still cite the outdated 5g figure. For a full comparison of recreational vs. medical limits, see Possession Limits.
Many websites and even some dispensary staff still cite the old 5-gram concentrate limit. The correct limit as of 2023 is 10 grams of concentrate within the 2.5-ounce total.
Statewide Delivery: A Game-Changer
One of Maine's most consumer-friendly features is statewide legal delivery. Licensed retailers can deliver cannabis to any address in Maine, even in municipalities that have opted out of retail stores. This means that even if your town does not have a dispensary, you can still legally receive cannabis at your door.
The Opt-In Reality: Only 15% Allow Retail
Maine uses an opt-in system for cannabis businesses. Municipalities must actively vote to allow retail cannabis operations. The result is stark:
- Only about 75 municipalities (~15%) allow retail dispensaries
- Approximately 128 municipalities (~26%) allow some type of cannabis license
- 85% of Maine's ~500 municipalities do not allow retail cannabis
- As of early 2026, there are approximately 237 retail storefronts statewide
Municipal fees vary dramatically, from $100 to $40,000. Portland caps its licenses at 20 with a $10,000 fee.
However, local opt-outs only affect businesses. Personal possession, home cultivation, and use remain legal statewide regardless of where you live.
Where You Can Consume
| Location | Status |
|---|---|
| Private residence/property with owner permission | Legal |
| Public places (streets, sidewalks, parks) | $100 fine |
| Cannabis lounges / social consumption | Not legal (LD 1365 pending) |
| Inside a vehicle | Illegal |
| Federal land (Acadia National Park) | Illegal — federal law applies |
| Schools and workplaces | Illegal |
Cannabis consumption lounges were part of the original voter initiative but were stripped out during legislative implementation. LD 1365 is a pending bill that would restore social consumption venues. For details, see Where You Can Consume.
Home Cultivation
Maine allows generous home growing under Title 28-B:
- 6 mature plants, 12 immature plants, and unlimited seedlings per person
- Plants must be tagged with your name and ID number
- Plants must not be visible from a public way
- Municipalities cannot ban home cultivation — a minimum of 6 plants per resident is guaranteed by state law
- Renters need written landlord permission
For complete cultivation rules, see Home Cultivation.
Taxes
| Tax Type | Adult-Use (Jan 2026+) | Medical |
|---|---|---|
| Sales tax on retail | 14% (was 10%) | 5.5% (standard rate) |
| Excise tax on flower (cultivator) | $223/lb (was $335) | None |
| Excise tax on trim (cultivator) | $63/lb (was $94) | None |
Tax restructure effective January 1, 2026. Medical cannabis pays only the standard 5.5% sales tax — no excise tax. Cumulative tax revenue exceeds $150 million since inception.
Employment Protections
Unlike most legal states, Maine provides among the strongest employment protections in the nation for cannabis users. Under 28-B M.R.S. §1501, employers cannot refuse to hire someone solely for off-duty cannabis use. A positive drug test alone is insufficient grounds for adverse action.
