Overview: Maine's Penalty Structure
Maine takes a tiered approach to cannabis penalties. Minor violations like public consumption are treated as civil infractions with modest fines, while more serious offenses like unlicensed sale and repeat OUI carry criminal charges. Maine was the third state to decriminalize cannabis in 1976, and that legacy is reflected in the relatively light penalties for personal-use violations.
Cannabis Penalty Table
| Offense | Classification | Penalty |
|---|---|---|
| Public consumption | Civil violation | $100 fine |
| Over limit (2.5–8 oz) | Class E crime | Up to 6 months / $1,000 |
| Open container in vehicle | Civil violation | Fine |
| OUI first offense | Criminal | $500 min fine + 48 hrs jail |
| OUI fourth offense | Class C felony | 6 months min jail |
| Unlicensed sale | Criminal | Varies by quantity |
Public Consumption: $100 Fine
Consuming cannabis in any public place is a civil violation carrying a flat $100 fine. This includes streets, sidewalks, parks, beaches, and outdoor areas of businesses. Key points:
- It is a civil violation, not a criminal offense
- No arrest, no jail, no criminal record
- Law enforcement issues a citation similar to a parking ticket
- Applies to all forms of consumption (smoking, vaping, edibles in public view)
For full details on legal consumption locations, see Where You Can Consume.
Over-Limit Possession: Class E Crime
Possessing more than 2.5 ounces but less than 8 ounces of cannabis (as a recreational user) is a Class E crime:
- Up to 6 months in jail
- Up to $1,000 fine
- This is a criminal offense that results in a criminal record
Amounts above 8 ounces carry increasingly severe charges. Medical patients with valid certification who are within the 8-pound limit are not subject to these penalties.
Open Container in Vehicle
Having an open or previously opened cannabis container accessible to the driver or passengers is a civil violation carrying a fine. To avoid this:
- Keep cannabis in its original sealed packaging
- Store in the trunk or a locked compartment
- Never leave accessible cannabis products in the cabin
OUI (Operating Under the Influence) Penalties
Cannabis OUI penalties under 29-A M.R.S. §2411 escalate sharply with repeat offenses. Maine uses an impairment-based standard with no per se THC blood level.
| Offense | Classification | Minimum Fine | Minimum Jail | License |
|---|---|---|---|---|
| 1st OUI | Criminal | $500 | 48 hours | 150-day suspension |
| 2nd OUI | Criminal | $700 | 7 days | 3-year revocation |
| 3rd OUI | Criminal | $1,100 | 30 days | 6-year revocation |
| 4th+ OUI | Class C felony | — | 6 months | 6-year revocation |
For a detailed explanation of how impairment is determined, see DUI & Driving.
Unlicensed Sale
Selling cannabis without a license or caregiver registration is a criminal offense with penalties varying by quantity. This includes:
- Selling homegrown cannabis
- Operating an unlicensed delivery service
- "Gifting" schemes that involve any form of compensation
Federal Land Penalties
Cannabis possession or use on federal land — including Acadia National Park — is subject to federal penalties, not Maine state penalties. Federal law classifies cannabis as a Schedule I controlled substance, and possession can result in federal misdemeanor charges regardless of the amount.
What Won't Get You in Trouble
It is worth emphasizing what is not a crime in Maine:
- Possessing up to 2.5 ounces (21+ with valid ID) anywhere in the state
- Growing up to 6 mature, 12 immature, and unlimited seedlings per person at home
- Consuming on private property with owner permission
- Purchasing from a licensed retailer or registered caregiver
- Receiving delivery statewide, even in opted-out municipalities
- Being a medical patient — no penalties for patient status under §2430-C
Employment Context
Unlike most states, cannabis-related civil violations in Maine are unlikely to affect your employment. Maine has among the strongest employment protections in the nation for cannabis users. Employers cannot refuse to hire solely for off-duty cannabis use, and a positive drug test alone is insufficient for adverse action.
