Maine Cannabis Laws

Though adult-use marijuana was legalized in 2016, Maine did not establish regulations for commercial sales until 2019, when Gov. Janet Mills signed LD 719 to approve a ruleset.

OMP is currently engaged in licensing adult-use marijuana establishments through the process required by the MLA and program rule. The first active adult use establishment licenses were issued on Tuesday, September 8, 2020. Although the opening of cannabis stores was delayed due to COVID-19, sales finally began as of October 9, 2020. This page is informational only and should not be considered legal advice.

Step Three: Active Licensure Supplemental information required for the issuance of an active license includes evidence of compliance with all electrical and permitting requirements and appropriate tax information and documents. Upon satisfaction that all requirements have been met, OMP will invoice the applicant for the licensing fee. Once payment is received, OMP will issue an active license that is valid for one year.
