Short answer
Rules for patients under 18 in California are set by the California Department of Public Health and are stricter than the rules for adults. Where a minor can qualify, a parent or legal guardian is typically required to give consent and act as caregiver.
Key takeaways
- Check the California Department of Public Health’s current rules for minors before you book; requirements differ by state.
- A parent or legal guardian books and attends the evaluation with the minor.
- Some states require extra steps for minors, such as a second physician or a specialist.
- Ask the physician how California’s rules apply to your child’s condition.
California was the first U.S. state to legalize medical marijuana, back in 1996. But age rules still apply. The minimum age to get a medical marijuana card in California is 18 years old for patients applying independently. Patients under 18 can still participate — but an approved caregiver who is at least 21 must apply on their behalf. Here is the complete breakdown.
Age Requirements in California’s Medical Program
Under the Compassionate Use Act and the Medical and Adult-Use Cannabis Regulation and Safety Act (MAUCRSA), California sets these age rules:
- 18 and older: Can apply for a medical marijuana recommendation and obtain a Medical Marijuana Identification Card (MMIC) without parental consent
- Under 18: Can access medical cannabis with an approved caregiver who is at least 21 years old
There is no lower age limit for minor patients. A child of any age may qualify if they have a serious medical condition and all legal requirements are met.
Qualifying Conditions in California
California has one of the broadest qualifying condition lists in the country. Physicians can recommend cannabis for any condition they believe a patient would benefit from, including:
- Cancer, anorexia, HIV/AIDS, glaucoma, arthritis, migraines
- Seizures including epilepsy, muscle spasms including from multiple sclerosis
- Chronic pain, cachexia or wasting syndrome, severe nausea
- Any other serious medical condition where cannabis may provide relief
This open language makes California’s program one of the most accessible in the country for a wide range of patients.
Caregiver Rules for Minor Patients
When a patient is under 18, their caregiver must:
- Be at least 21 years old
- Be approved as an official caregiver through the California Department of Public Health (CDPH)
- Be responsible for purchasing, transporting, and administering the cannabis
- Accompany the minor during any dispensary visit
California also passed Jojo’s Act in 2019, which allows K–12 schools to permit the possession and use of non-inhalable medical cannabis products on school grounds under parental supervision.
How to Get a Medical Marijuana Card in California
Step 1See a licensed California physician
You need a written recommendation confirming your qualifying condition. Telehealth evaluations are widely available across the state.
Step 2Decide on the MMIC (optional)
The Medical Marijuana Identification Card is not mandatory in California. A doctor’s recommendation alone is legally sufficient. However, an MMIC provides additional legal protections and sales tax exemptions.
Step 3Submit required documents
These include proof of California residency, your physician recommendation, and a current passport-style photo.
Step 4Pay the applicable fees. MMIC fees vary by county
Medi-Cal patients may qualify for fee waivers.
Step 5Shop at any licensed California dispensary
With your recommendation, you can legally purchase cannabis products statewide.

Benefits of a Medical Card Over Recreational
California legalized recreational cannabis in 2016 (Proposition 64) for adults 21 and older. Even in a state with legal recreational use, a medical card offers clear advantages:
- Lower taxes — medical patients are exempt from the state excise sales tax on cannabis
- Higher possession and purchase limits
- Access to higher-potency products
- Broader product selection at dispensaries
Pricing Information
- Doctor’s recommendation: $40–$100 (many telehealth options available)
- MMIC county application fee: Around $100 (reduced for Medi-Cal patients)
- Medi-Cal patients: May receive full fee waivers through their county health department
