How to get a medical card in California
Because adult use is legal, "getting a card" in California really means two separate, optional steps. Do the first if you want medical-patient status; add the second if you want the tax break.
- 1. Get a physician's recommendation. A California-licensed physician evaluates you — this can be done by telehealth — and, if appropriate, issues a written recommendation under Prop 215. That document makes you a qualified patient and is typically valid for one year. Approval is often same-day.
- 2. (Optional) Apply for the state MMIC. Take your recommendation, a government photo ID, and proof of county residency to your county Public Health Department, and pay the fee (up to $100). The card is registered with the California Department of Public Health (CDPH) and arrives by mail. This step is voluntary — its main benefit is the sales-tax exemption described below.
So who should bother? If you're under 21, the recommendation is what gives you legal access at all. If you buy regularly, the MMIC's tax savings usually outweigh its cost within a few months. If you're an occasional adult-use buyer over 21, you may not need either. Our guide on medical vs. recreational breaks down the trade-offs.
Qualifying conditions in California
Under California Health & Safety Code §11362.7, qualifying conditions include:
- Cancer
- HIV/AIDS
- Anorexia and cachexia (wasting syndrome)
- Arthritis
- Chronic pain
- Glaucoma
- Migraine
- Persistent muscle spasms, including those from multiple sclerosis
- Seizures, including those from epilepsy
- Severe nausea
Crucially, California's list ends with a catch-all: any other chronic or persistent medical symptom that substantially limits a major life activity or that, if not relieved, could cause serious harm to your safety or physical or mental health. That open-ended clause is why conditions such as anxiety, PTSD, and insomnia are commonly certified in California even though they aren't named individually. See the qualifying conditions overview for the wider picture.
Cost breakdown
There's no mandatory state fee for the recommendation route. Your costs are:
- Physician's recommendation — typically about $40–$100. Set by the provider, not the state. Many telehealth services issue it the same day, and it lasts a year.
- State MMIC (optional) — up to $100. The fee is set by your county and capped at $100 statewide. Medi-Cal beneficiaries pay half (often $50 or less), and some counties charge less to begin with (San Diego, for example, is $44 / $22 for Medi-Cal). Indigent patients in the County Medical Services Program can have the fee waived.
- Tax savings. With the MMIC you skip sales & use tax — roughly 7.25% to 10%+ depending on locality — on medical cannabis. For regular buyers, that often recovers the MMIC fee within a few months. See our cost of an MMJ card guide.
Note: health insurance does not cover any of these costs, because cannabis remains federally illegal.
Possession & purchase limits
Medical patients get higher limits than adult-use buyers. Under H&S §11362.77, a qualified patient may possess:
- Up to 8 ounces of dried cannabis (versus 1 ounce for adult-use), and
- 6 mature or 12 immature plants.
A physician may recommend amounts greater than these if consistent with your medical needs. Unlike many states, California allows home cultivation — qualified patients follow the §11362.77 plant counts, while adult-use households may grow up to 6 plants. See possession limits by state for how California stacks up.
Renewal rules
Both layers run on a yearly cycle:
- Physician's recommendation — renew annually. Most recommendations are valid for one year, and renewals can again be handled by telehealth. A physician can specify a shorter period.
- State MMIC — valid 12 months. Renewing the MMIC repeats the original county application process, and you'll need a current recommendation on file.
There's no mid-cycle recertification requirement like Florida's — once a year keeps both documents current.

Frequently asked questions
Do I even need a medical card if recreational is legal in California? +
Not to buy, if you're 21 or older. But a physician's recommendation lowers the access age to 18, raises your possession and cultivation limits, and is required for the optional state MMIC — which is the only document that exempts you from sales & use tax. Frequent buyers and patients under 21 benefit most.
Can I get a California medical cannabis recommendation by telehealth? +
Yes. A California-licensed physician can evaluate you over a secure video visit and issue the recommendation the same day. The optional state MMIC, however, is applied for in person at your county Public Health Department.
How much does a California medical card cost? +
The physician's recommendation typically runs about $40–$100. The optional state MMIC costs up to $100 (set by your county, capped statewide), with Medi-Cal patients paying half. Insurance covers none of it.
What conditions qualify in California? +
Named conditions include cancer, HIV/AIDS, anorexia, cachexia, arthritis, chronic pain, glaucoma, migraine, persistent muscle spasms, seizures, and severe nausea. A broad catch-all also covers any other chronic or persistent symptom that substantially limits major life activities — which is how conditions like anxiety and PTSD are commonly certified.
Can I grow my own cannabis in California? +
Yes. Qualified medical patients may cultivate 6 mature or 12 immature plants under H&S §11362.77, and a physician can recommend more if medically justified. Adult-use households may grow up to 6 plants.
Does a medical card exempt me from tax? +
Only the state-issued MMIC exempts you from sales & use tax (about 7.25%–10%+). A doctor's recommendation alone does not. Either way, you still pay California's 15% cannabis excise tax.
