Maine Cannabis Regulations: License Applications, Forms, Links, and Other Resources

This document is intended to provide an overview of Maine cannabis regulations as they apply to growers, processors, labs, and dispensaries. It includes some basic information on how to get a marijuana business license in Maine as well as a comprehensive list of links to forms and applications and additional resources. This information was last updated on 1/3/2019.

Maine's medical cannabis law was first passed in 1999. However, the measure allowed patients to grow their own plants and the regulations related only to medical marijuana. Although marijuana was decriminalized in Maine it was not legalized for adult use until 2016.

In November 2016, Maine voters approved a measure calling for the legalization, taxation, and regulation of marijuana in a manner similar to alcohol. Subsequently, marijuana legalization bills went through numerous rewrites only to get vetoed on the first round. Then in 2018, Maine lawmakers overrode the governor’s veto and enacted legal code LD 1719, An Act to Implement a Regulatory Structure for Adult Use Marijuana. The move made Maine the 8th state to legalize recreational marijuana. Information about the bill can be found here

P.L. 2017, ch. 409 took effect on in May of 2018 enacting Title 28-B of the Maine Revised Statutes and repealed 7 M.R.S.A. Chapter 417. As stated in the preamble of P.L. 2017, ch. 409, the measure was intended to "to facilitate the timely implementation of a retail marketplace in the State for adult-use marijuana and adult-use marijuana products, the agencies charged by law with the implementation, administration, and enforcement of the Marijuana Legalization Act must adopt rules in accordance with that Act and the Legislature must review those rules in accordance with the Maine Administrative Procedure Act as soon as is practicable." 

On June 27, 2019, Governor Mills signed into law 129th LD 719, which became P.L. 2019, ch. 491. Among other changes to Maine's adult-use marijuana laws, P.L. 2019, ch. 491 requires several changes to the provisionally adopted rules

The final rules are not expected to be finalized until early 2020. 

Maine’s combined medical and recreational cannabis market is projected to top $252 million in its second year of recreational cannabis sales.
