Does Maine accept out-of-state medical cards?
Yes. Visiting patients from 28 approved jurisdictions can buy with their home-state card or other state-issued patient documentation, up to 2.5 oz every 15 days.
Traveling from Maine
Your Maine card is issued under Maine law, so other states decide for themselves whether to honor it. Never carry cannabis across state lines — that's a federal offense, including on flights.
