Under 28-B M.R.S. §§ 1501–1502, Maine adults 21+ may cultivate 3 mature and 12 immature plants plus an unlimited number of seedlings, and may transfer without remuneration up to 6 immature plants or seedlings to another adult; licensed cannabis stores lawfully sell — and may even deliver — seeds and seedlings to any adult. Medical caregivers and dispensaries also supply genetics under Title 22. Growing hemp still requires a license from the Department of Agriculture, Conservation and Forestry under 7 M.R.S. ch. 406-A, so viable hemp seed for planting is limited to licensed growers.
