The Short Answer: Yes, Cannabis Is Fully Legal

Cannabis is legal in Maine for adults 21 and older. On November 8, 2016, Maine voters approved Question 1 with 50.26% of the vote — a margin of just 3,995 votes, the narrowest cannabis legalization victory in U.S. history. The law is codified under Title 28-B of the Maine Revised Statutes.

Maine's cannabis history runs deep. The state decriminalized cannabis in 1976, making it only the third state in the nation to do so. Medical cannabis followed in 1999, making Maine the fifth state with a medical program. Today, Maine operates one of the most unusual dual-market systems in the country, with a massive caregiver-driven medical market that actually outsells the licensed recreational market.

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.

A Brief History of Cannabis in Maine

  • 1976: Maine decriminalized cannabis possession, becoming only the third state in the nation to do so.
  • 1999: Voters approved medical cannabis, making Maine the fifth state with a medical program.
  • 2009: Major expansion of the medical program established the caregiver system that would grow into a parallel market.
  • 2018: Qualifying conditions for medical cannabis eliminated entirely — any patient with a physician's recommendation qualifies.
  • November 8, 2016: Question 1 passed with 50.26% — just 3,995 votes. Governor LePage opposed the measure and used vetoes and delays to stall implementation.
  • October 9, 2020: First licensed recreational sales finally began, nearly four years after voters approved legalization.

Vote Margin — Narrowest Cannabis Legalization in U.S. History

Why Did It Take Four Years for Retail to Open?

Maine holds the record for the longest gap between voter approval and first recreational sale. Governor Paul LePage, who opposed Question 1, vetoed implementation bills multiple times. The regulatory framework was not finalized until after LePage left office in January 2019, and the Office of Cannabis Policy did not begin accepting applications until late 2019. The first retail store opened on October 9, 2020.

Who Regulates Cannabis in Maine?

Maine's cannabis industry is regulated by the Office of Cannabis Policy (OCP), which operates within the Department of Administrative and Financial Services (DAFS). The OCP oversees both the adult-use (Title 28-B) and medical (Title 22 Chapter 558-C) programs.

The Opt-In Challenge

Unlike most legal states where municipalities opt out, Maine uses an opt-in system for retail cannabis. Only about 75 municipalities (roughly 15%) allow retail dispensaries, while approximately 128 (26%) allow some type of cannabis license. That means 85% of Maine's ~500 municipalities do not allow retail cannabis stores.

However, delivery is legal statewide — even into towns that have opted out of retail. Personal possession, use, and home cultivation are also legal everywhere.
