To use medical cannabis legally in California you need a written recommendation from a licensed California physician. The state Medical Marijuana Identification Card (MMIC) is optional and is issued by your county.
Many people use the phrase medical marijuana card to mean two different things: the physician's written recommendation and the state-issued Medical Marijuana Identification Card. This guide explains who is eligible for each, the documents you need, the steps to apply, what the county MMIC costs, and why some patients choose to get one while others rely on the recommendation alone.
You generally need to meet all of the following:
Adult-use cannabis is limited to people 21 and older. Adults 18 to 20 can buy from licensed medicinal retailers only with a valid physician recommendation.
The recommendation is the core legal document. It is what makes you a qualified patient under the Compassionate Use Act, and licensed medicinal retailers accept it along with your ID. The MMIC is a separate, voluntary photo card issued by your county health department under the state Medical Marijuana Identification Card Program run by the California Department of Public Health (CDPH).
Issued by your physician after an evaluation. Required for medical status. Usually valid for up to 12 months. Lets adults 18 and older shop at medicinal retailers and use medical possession and cultivation limits.
Optional. Issued only by your county health department, never by a physician or evaluation center. Valid for up to one year. Provides a safe harbor from arrest within state limits and exempts purchases from sales and use tax.
For the physician evaluation, have a government-issued photo ID and any relevant medical information, such as a medication list or records from other providers. For the county MMIC, state law (section 11362.715) and CDPH require:
Most patients follow this order:
Each county sets its own MMIC fee, capped by state law at 100 dollars per application or renewal. Medi-Cal beneficiaries receive a 50 percent reduction, and the fee is waived for enrollees in the County Medical Services Program. For the cost of the physician evaluation, see /cost/.
Recommendations and MMICs both expire, typically after 12 months. A caregiver's MMIC expires when the patient's card does. Renewal requires a new evaluation for the recommendation and the same county process for the MMIC, which issues a new card number. See /renew/ for timing tips.
Your county keeps MMIC information confidential under state medical privacy law. The state's online verification system shows only the card number and whether it is valid, not your name or diagnosis.

No. Licensed medicinal retailers accept a valid physician recommendation with government-issued photo ID. The MMIC is optional, but it is required to receive the sales and use tax exemption.
No. CDPH states that an MMIC can be obtained only through your county program, not through a physician or evaluation center. The county application is made in person.
Yes. The physician recommendation is for California residents, and the MMIC must be obtained in the county where you live, with proof of residency.
Adults 18 and older can qualify on their own. Minors need a parent or legal guardian to consent and participate, and the guardian generally serves as primary caregiver.
No. Physicians recommend cannabis rather than prescribe it, and you buy it from state-licensed retailers rather than a pharmacy.
Approval is never guaranteed. The physician must find that you have a qualifying condition and that cannabis is medically appropriate for you.
