About

Based in Portland, Regan A. Sweeney handles cannabis and marijuana law matters in Maine. Admitted 18 years ago, Sweeney studied law at American University. Alongside cannabis matters, Sweeney handles landlord and tenant matters, including leases at licensed premises, license applications, agency hearings and appeals of regulator decisions and business formation and transactional work for operators and their investors.

Maine regulates both adult-use and medical cannabis, so legal work in the state runs from licensing and local approvals through packaging, advertising and seed-to-sale tracking rules, alongside the criminal matters that still arise around unlicensed activity and possession above the legal limit. Regulation runs through the Office of Cannabis Policy.
