Does cancer qualify for a medical card in California?

Yes. The Medical Marijuana Identification Card Program (MMICP) lists Cancer as a qualifying condition. A California-licensed provider still has to evaluate you and agree that cannabis is appropriate.

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 California 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 California

  1. See a licensed California physician who examines you (telehealth is allowed if it meets the standard of care) and documents a serious medical condition.
  2. Get a copy of the physician's recommendation; the state's Written Documentation form can be used.
  3. Complete the CDPH Application/Renewal Form.
  4. Gather a government photo ID and proof of residency in your county.
  5. Make an appointment with your county's MMIC program office and apply in person.
  6. Pay the county fee (up to $100, reduced for Medi-Cal) and have your photo taken.
  7. Pick up your card once the county verifies the application, usually within 35 days.

California allows the evaluation by telehealth, so you can see a California-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 California provider will tell you if more is needed.

How long does certification take in California?

The provider visit takes about 15 minutes. County has 30 days to verify and 5 more days to issue the card; up to 35 days total for a complete application.

Can I renew online in California?

In most cases, yes. Renewal follows the same in-person county process as a new application and produces a new card number. Your existing medical documentation can be used if it is still valid.
