Common Questions

Medicinal Marijuana Laws

California led the nation in legalizing medicinal marijuana. Under California law, patients who meet certain requirements can obtain and use marijuana legally with a doctor’s recommendation. Recreational use has also recently been legalized in California (see our article on recreational marijuana rules), but all marijuana use remains illegal under federal law.  If you’re thinking about using medicinal marijuana, here’s what you need to know.

California, local, and federal laws on medical marijuana


Medical use of marijuana/cannabis has been legal since Proposition 215, the “Compassionate Use Act,” passed in 1996 (Cal. Health & Safety (H&S) § 11362.5). After Proposition 64 legalized recreational marijuana, the legislature passed the passed the “Medical and Adult-Use Cannabis Regulation and Safety Act” (“MAUCRSA”), creating a combined regulatory system for both medical and recreational marijuana.  (Read NORML’s summary here:

These rules permit and regulate for-profit cultivation, distribution, manufacturing, testing, dispensary, and transportation, with permits required from both local and state agencies.  Temporary state licenses became available starting January 1, 2018.

For the most part, these rules do not affect individual patients, as long as they cultivate solely for personal medical use and limit their growing area to 100 square feet. Primary caregivers can cultivate up to 500 square feet for the personal medical use of up to five patients without falling under the new rules.

City and County Laws

Many cities and counties prohibit or regulate dispensaries and the cultivation of marijuana. Any county or city may have its own unique ordinances. Most are available on the internet.

Due to the rapid changes in the law and the ongoing debates over marijuana, many local governments are currently revising their ordinances and placing tax and other measures before their voters. To review current ordinances, visit the California NORML web page on “Local Medical Marijuana Cultivation & Possession Guidelines in California” ( or check the most recent ordinances in your area by contacting your city or county.

Federal Law

Marijuana use, possession, and distribution is illegal under federal law. 21 U.S.C. § 801 et seq. There is no exception or special treatment for medical use, and California law cannot override federal law.

In January, 2018, the Trump administration reversed the Obama Department of Justice’s hands-off policy. Individual U.S. attorneys are free to pursue marijuana violations as they see fit. This change means the future of the medicinal (and recreational) marijuana industry in California is uncertain.

Common questions about medical marijuana

Do I still need a medical recommendation?  

Patients with a doctor’s recommendation can grow or possess larger quantities of marijuana than recreational users. In addition, if you are under 21, you must have a doctor’s recommendation to purchase marijuana. (Note: some dispensaries have discontinued sales to patients under 21, even with recommendation, to fit within recreational dispensary rules.) Finally, a county-issued medical marijuana ID card exempts you from tax on marijuana purchases.

How do patients get medical marijuana recommendations?

Doctors do not “prescribe” marijuana. Federal law specifically prohibits prescription of Schedule I drugs, including marijuana. Instead, doctors can “recommend” marijuana for appropriate conditions. Patients who are living with “cancer, anorexia, AIDS, chronic pain, spasticity, glaucoma, arthritis, migraine, or any other illness for which marijuana provides relief” are mentioned in Prop. 215. Physicians have recommended marijuana for numerous other conditions, including insomnia, depression, anxiety, PTSD, and many more.

Most medicinal marijuana recommendations are made by doctors who specialize in evaluating patients for recommendation, rather than the patients’ usual physician. The recommending doctor should review patients’ existing medical records before making a recommendation, including reviewing any other medications the patients are already using.

How do patients acquire marijuana, and how much can they possess? 

Senate Bill 420 (2003) authorizes individual patients (and their caregivers) to possess up to six mature or 12 immature plants and eight ounces of dried cannabis. Patients can grow their own marijuana, or purchase it from licensed dispensaries. It is not legal to sell without a license.

Cities and counties may raise the limits on quantity if they choose (although more than 100 square feet would subject the individual to the new licensing requirements.) They can also impose zoning restrictions preventing dispensaries or prohibiting outdoor cultivation, so check local codes.

What is a Medical Marijuana ID card, and how do patients get one?

A Medical Marijuana ID card is optional—patients do not need to get one to use medical marijuana legally, just a doctor’s recommendation. However, it can be very useful. It exempts the patient from paying taxes on marijuana purchases. In addition, the ID card prevents law enforcement from arresting a patient with permissible amounts of marijuana (which may exceed the legal recreational limits).

Cards are issued by county Departments of Public Health. There is a charge for the card; currently the fee is $100 annually ($50 with proof of Medi-Cal benefits) in Sacramento County (“Medical Marijuana Identification Card – Frequently Asked Questions,” Sacramento County Department of Health and Human Services).

Return of marijuana seized during a police stop or arrest

Law enforcement officers sometimes confiscate (seize) marijuana during investigations, whether or not they arrest the patient. The patient is entitled to the return of the property, but in some cases, it is not as easy as just requesting it back.

If the police department will not return the marijuana upon request, the patient can file a motion for return of property. Information and samples for doing this are available at the Law Library or on the website of Americans for Safe Access (ASA). This website also has information on patients’ legal rights when dealing with law enforcement as well as practical tips on growing and using medicinal marijuana.
