Maine Cannabis Penalties

From a $100 public consumption fine to Class C felony OUI charges — here's a complete breakdown of what happens when you cross the line under Maine cannabis law.

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)

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

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.
