Cancer and medical marijuana in Maine: do you qualify?

By MyMMJRx Editorial Team · Updated · 5 min read

Very likely. Maine doesn't limit certification to a fixed list — providers can recommend cannabis for conditions they believe it will help. That includes patients with cancer when the provider agrees it's appropriate.

Yes. Maine has no fixed condition list; providers may certify any patient whose diagnosis they believe may be eased by therapeutic or palliative cannabis use.

About cancer

Cancer and its treatment — chemotherapy, radiation, surgery — can cause pain, nausea, vomiting, appetite loss and trouble sleeping.

Stronger evidence. The National Academies found conclusive evidence that oral cannabinoids prevent and treat chemotherapy-induced nausea and vomiting. There is not enough evidence that cannabis treats or cures cancer.

Symptoms Maine patients most often hope to ease:

  • Nausea and vomiting from chemotherapy
  • Loss of appetite and unwanted weight loss
  • Cancer-related pain
  • Burning or tingling nerve pain from chemotherapy
  • Trouble sleeping
Before you start. CBD can affect liver enzymes that process some chemotherapy and targeted drugs, so your oncology team must know about any cannabis you use. A few small studies have raised questions about whether cannabis use may affect how well immunotherapy works, which is worth discussing with your oncologist.

How to get certified in Maine

  1. Book a visit with a Maine-licensed physician, nurse practitioner or physician assistant who certifies patients for medical cannabis.
  2. Have a full medical-history assessment, either in person or by live video. In-person is required if you don't give your primary care provider's contact details.
  3. Get your written certification on tamper-resistant paper, which the provider may also send as a matching digital image.
  4. Keep the certification with you and show it at medical dispensaries or to a registered caregiver.
  5. If you want someone else to grow for you, sign a caregiver designation form. You may also grow at home within the plant limits.

Maine allows the evaluation by telehealth, so you can see a Maine-licensed provider by video. Our evaluation starts at $79 and is charged only if you're approved.

Frequently asked questions

Do I need medical records for cancer?

Helpful records include: pathology or imaging reports confirming your cancer diagnosis; recent notes from your oncologist describing your stage and current treatment plan; a full list of medicines, including chemotherapy, anti-nausea drugs, pain medicines and blood thinners. Many patients are still evaluated on their history alone, and your Maine provider will tell you if more is needed.

How long does certification take in Maine?

The provider visit takes about 15 minutes. Certification is issued by the provider at the visit; there is no state application to process.

Can I renew online in Maine?

In most cases, yes. Before your certification expires (after one year at most), see a provider again for a new one. Renewals can be done by live telehealth.
