Short answer: a California medical marijuana card takes two separate steps. First, a physician licensed in California examines you and documents a recommendation for medical cannabis. Second, you apply in person to your county health department for the state Medical Marijuana Identification Card (MMIC), which is voluntary and carries a county fee capped at $100. The physician cannot issue the card, and neither can an evaluation center.
HealthDataConsortium.org is a publisher, not a clinic and not a government office. The steps below follow the California Department of Public Health (CDPH) card pages. For how card programs differ from state to state, see our how state card programs differ overview.
Recommendation or card: which one do you need?
The two documents are often both called a “medical card,” but they do different jobs.
| Question | Physician’s recommendation | Medical Marijuana Identification Card (MMIC) |
|---|---|---|
| Who issues it | A physician licensed in California, who examines you | Your county health department, under the state program run by CDPH |
| What it lets you buy | Medicinal cannabis from a licensed retailer, if you are 18 or older (Department of Cannabis Control) | Shows your identity and status; with a government ID, it removes sales and use tax on medicinal cannabis |
| Is it required? | Yes, for medicinal purchases | No. Participation in the program is voluntary (CDPH) |
Adults 21 and older can buy adult-use cannabis from a licensed retailer without any card. Your physician gives you the recommendation, and the county gives you the card.
How do you get a medical marijuana card in California?
You apply in person in the county where you live. CDPH’s card FAQ gives the documents and steps in this order:
- Fill out the Application/Renewal Form, CDPH 9042, which you can download from the CDPH forms page.
- Bring a copy of your medical recommendation.
- Bring proof of identity: a valid California DMV driver license or ID card, or another valid government-issued photo ID card.
- Bring proof of residency, such as a rental or mortgage agreement, a utility bill, or a California DMV motor vehicle registration.
- Contact the health department in your county of residence to make an appointment.
- Pay the fee your county program requires, which may not exceed $100.
- Have your photo taken at the county office, or provide an electronic photo if the Health Department allows it. The photo appears on your MMIC.
CDPH says the photo and certain verifications must be completed in person. Your county may also ask for documents beyond this list, and you must authorize your physician to release medical information to the county program, which cannot process your application without that authorization.
What your physician must do, and what to tell them
CDPH’s roles and responsibilities page says the physician must hold a license in good standing from the Medical Board of California, the Osteopathic Medical Board of California or the California Board of Podiatric Medicine. The physician must examine you, document in your medical record that you have a serious medical condition and that the medical use of marijuana is appropriate, and give you copies of that record.
When you talk to your doctor, describe the symptoms and condition you have, and ask whether medical cannabis is appropriate for you. That decision is your physician’s to make after an exam. Ask whether they will use the Written Documentation of Patient’s Medical Records form (CDPH 9044). The CDPH card FAQ says this form can stand in for copies of your medical records, with the original going to the county with your application.
The state does not refer physicians. The CDPH card FAQ says the program does not maintain lists of physicians and is not a referral service, so finding a physician is up to you.
Which conditions qualify?
CDPH lists these serious medical conditions for the card:
- AIDS
- anorexia
- arthritis
- cachexia (wasting syndrome)
- cancer
- chronic pain
- glaucoma
- migraine
- persistent muscle spasms (such as spasms associated with multiple sclerosis)
- seizures (such as epileptic seizures)
- severe nausea
The list ends with a catch-all: any other chronic or persistent medical symptom that substantially limits a person’s ability to conduct one or more major life activities as defined in the federal Americans with Disabilities Act of 1990, or if not alleviated, may cause serious harm to the person’s safety, physical, or mental health.
Can you get a medical card for anxiety?
The CDPH card FAQ’s list does not name anxiety. Whether your anxiety fits the catch-all is for your physician to decide after an exam, and the decision is documented in your records.
For context, a 2011 study of nine California clinics sampled 1,746 patients at medical marijuana evaluation clinics and found that pain, insomnia and anxiety were the most common conditions for which evaluating physicians recommended medical marijuana. That study describes who was recommended for what. It does not measure whether cannabis helps them.
A qualifying condition gives you legal access to the card. It is not proof that cannabis helps.
Can I get a medical card at 18?
At 18 you are an adult under the state’s rules, so you apply the way any adult patient does. The minor rules in the CDPH card FAQ cover people under 18. The Department of Cannabis Control says you can buy cannabis if you are 18 or older with a physician’s recommendation (medicinal use), from a licensed retailer.
Minors under 18
A minor under 18 can apply as a patient or caregiver under certain conditions. A minor who is lawfully emancipated or has declared self-sufficiency can apply for themselves. If the minor has not done either, the county program contacts the minor’s parent, legal guardian or person with legal authority to make medical decisions for the minor. A minor can use a government-issued photo ID, such as a California driver license or California ID, and a certified copy of a birth certificate can be sufficient proof of identity. An emancipated or self-sufficient minor may need additional documents, so ask the county.
Who can be a primary caregiver, and how do they apply?
A primary caregiver is a person who is consistently responsible for the housing, health or safety of a qualified patient. A caregiver must be at least 18, unless they are an emancipated minor or the parent of a minor who is a qualified patient.
Only the patient can apply. The patient fills in the Application/Renewal Form and checks the primary caregiver box. The caregiver must apply in person at the patient’s county program, with photo ID, and pay the fee. If a caregiver works for more than one qualified patient, they must live in the same county as each of them. A caregiver’s card expires when the patient’s card expires, even if it is less than 12 months.
What does the card add?
A sales tax exemption. Medicinal cannabis sold to qualified patients or their caregivers is exempt from sales and use tax when they furnish both a valid MMIC and a valid government-issued ID, according to the California Department of Tax and Fee Administration’s cannabis retailers page. That exemption does not apply to the cannabis excise tax.
An ID that can be verified. The card carries a nine-digit ID number, and retailers may verify it on CDPH’s website. The CDPH card FAQ says the registry lets law enforcement and the public verify a card’s validity.
Possession amounts. The CDPH card FAQ cites Health and Safety Code section 11362.77 for the rule that a qualified patient or primary caregiver may possess no more than eight ounces of dried marijuana per qualified patient, and no more than six mature or twelve immature marijuana plants. These are possession figures under that statute.
Medicinal rules. The Department of Cannabis Control’s What’s legal page says medicinal users have higher possession limits, can grow more plants at home if their physician recommends it, and can buy more cannabis each day if their physician recommends it. Check that page for the current buying rules.
Is a medical card worth it in California?
It depends on what you need. Adults 21 and older do not need a card to buy adult-use cannabis, so many adults will not need one. The card is worth considering if you want the sales tax exemption, an ID that retailers and police can verify, or the medicinal limits that come with a physician’s recommendation. The excise tax still applies with the card, and the card has its own fee and its own renewal.
How much does a California medical card cost?
Keep three figures separate: the state fee, the physician visit, and the renewal clock.
| Item | What the state says | Who sets it |
|---|---|---|
| County application fee (state fee) | Up to $100 per application or renewal (CDPH card FAQ) | Your county program, within the $100 cap |
| Medi-Cal beneficiaries | 50 percent reduction, not to exceed $50 (CDPH card FAQ) | State rule; the county verifies Medi-Cal participation |
| Indigent patients in the County Medical Services Program | Fee waived (CDPH card FAQ) | State rule |
| Renewal clock | Card valid up to one year; renewal repeats the application (CDPH card FAQ) | Your county program |
Fees vary by county, and the state publishes no single fee. Call your county program for its current amount. If you are a Medi-Cal beneficiary, your primary caregiver’s card is discounted 50 percent too, according to the CDPH roles page.
How long does it take, and how long does the card last?
Once you submit a complete application, the county has 30 days to verify it. After verification, the county program has five days to make the MMIC available. If the application is complete and nothing is denied, it can take up to 35 days. If something is missing, the county will contact you within 30 days of your submission. If you do not have your card within 35 days, contact your county program.
The MMIC may be valid up to one year. Renewing requires the same process as the original application. If your medical documentation is still valid you may use it, but you may need new documentation. Your county program will tell you what it needs.
What if your application is denied?
You can appeal a denial at no cost. Submit a completed Appeals Form, CDPH 9043, to CDPH within 30 calendar days, and mail it with a copy of your denial letter. The CDPH forms page counts the 30 days from the day you receive the denial notice, while the CDPH roles page counts them from the date on the notice. To be safe, count from the earlier date. CDPH’s appeal decisions are final.
Does California accept out-of-state medical cards?
No. The CDPH card FAQ says California does not recognize other states’ cards. If you are visiting and you are 21 or older, the Department of Cannabis Control says adults 21 and older can buy adult-use cannabis without any card.
Is an online medical card service legit?
Be careful with any site that charges you for a “card” or charges to fill in state forms. The CDPH card FAQ says you can obtain an MMIC only at your county program, not through your attending physician or an evaluation center. Any site that sells you a card is not the card program. The application forms are published on CDPH’s forms page, and you can apply directly with your county.
Once you are ready to buy, check that the store is licensed. The Department of Cannabis Control says some stores that look legitimate are not actually licensed, and stores without a license may sell untested products. Licensed retailers display their state license, and you can scan the QR code on the certificate to verify it.
Where do you apply in San Diego, Fresno or Los Angeles?
Each county runs its own card program. CDPH’s county program list includes San Diego, Fresno and Los Angeles counties, among the others. Call the county program where you live to set an appointment and confirm its fee.
What jobs can you not do with a medical card?
For how California law treats workplace drug tests and employment, read our california marijuana drug test employment law guide.
Indica or sativa, edibles or smoking: what should you choose?
The card rules do not decide which strain or form suits you, and they do not settle whether cannabis makes you high. Ask your recommending physician, who knows your condition, which form to consider. At a licensed retailer, check the label. The Department of Cannabis Control says licensed retailers must ensure the amount of THC and CBD on the label is accurate.
Before you apply
- Find your county on the county program list, then call to confirm the current fee, the appointment process and any extra documents.
- Ask your physician’s office what the recommendation visit costs before you book.
- Bring your recommendation copy, photo ID and proof of county residency to your appointment.
- Ask the county which date counts for an appeal if you are denied.
