You gotta grow it yourself or, get a caregiver to do it for you. Don't look for connections on this forum.

D. Access to Medical Marijuana
Medical marijuana patients cannot go to a pharmacy for medical marijuana. Pharmacies can only dispense medications that are "prescribed." Unfortunately, medical marijuana is classified by the federal government as a Schedule I drug which means that it cannot be "prescribed" by any health care professional.

Under Maine's medical marijuana law, doctors may only "recommend" marijuana, and that allows patients to grow their own medical marijuana for their private use. The state of Maine does not provide information on the acquisition of marijuana. Therefore, the State of Maine will not assist in getting seeds or plants to start growing medical marijuana.
