How Does Maine's Medical Cannabis Program Work?

Once certified, patients can legally obtain medical cannabis from licensed medical dispensaries or registered caregivers operating under Maine law.
Why Is Medical Marijuana Still Important in Maine?
Even though recreational cannabis is legal in Maine, many people continue to participate in the state's medical cannabis program.

The specific consequences depend on the nature of the violation and the circumstances involved.
