The state of play
A mature adult-use market with strong support for small and caregiver-scale growers.
Because Maine allows adult use, the practical questions are about quantity and place rather than permission. Public consumption is generally still restricted, driving in possession of an open product can create problems, and federal land inside the state stays off-limits regardless of state law.
Two things trip people up most: assuming a legal purchase elsewhere transfers across state lines (it doesn't — once you cross a border you're under a different rulebook, and possibly federal law), and forgetting that employers, landlords, and federal programs can still set their own rules even where the state says yes.
