Cannabis in California: Laws, Legal Status, Recreational & Medical Use

California was the first U.S. state to legalize medical cannabis in 1996 and later expanded to full adult-use legalization through Proposition 64 in 2016. The law allows adults aged 21 and older to purchase, possess, and cultivate cannabis for personal use while establishing a comprehensive tax and license structure. Today, California’s market is one of the largest and most complex in the world, overseen by the Department of Cannabis Control (DCC). The state continues to refine its framework, recently implementing major changes to hemp regulations and tax collection methods to support the legal industry and consumer safety.

Cannabis Legal Status in California

California permits both recreational and medical cannabis use. While the state has high possession limits and widespread retail access, local jurisdictions may still ban commercial activity, and use is restricted on federal lands within the state.

Recreational Cannabis Laws in California

Legal Age Requirements

Adults must be 21 years or older to purchase, possess, or consume recreational cannabis in California.

Possession Limits

• 28.5 grams (1 ounce) of dry cannabis flower
• 8 grams of concentrated cannabis
• 6 plants for personal home cultivation

Where Cannabis Can Be Purchased

Cannabis must be purchased from state-licensed retailers. These businesses are required to use the California Cannabis Track-and-Trace (Metrc) system to ensure all products are lab-tested and legally sourced.

Public Consumption Laws

State law generally prohibits public smoking or ingestion, with exceptions for authorized premises. Smoking is also prohibited where tobacco smoking is banned. The 1,000-foot school, daycare, and youth-center restriction applies while children are present and includes a limited private-residence exception where smoke is not detectable on those grounds.

Home Cultivation

Adults 21 and older may grow up to six plants per private residence under the state personal-use rules. Local governments may regulate cultivation and prohibit outdoor growing; they cannot completely prohibit compliant indoor cultivation. Plants must be secured and not visible from a public place. Check local rules and property restrictions.

Medical Cannabis in California

Medical Cannabis Program

California’s medical program, established by the Compassionate Use Act, allows patients to use cannabis with a doctor’s recommendation. The state issues voluntary Medical Cannabis Identification Cards (MMIC) that provide additional tax benefits and higher limits.

Qualifying Conditions

Qualifying conditions include cancer, anorexia, AIDS, chronic pain, glaucoma, migraines, persistent muscle spasms, seizures, and any other chronic or persistent medical symptom that limits major life activities.

Patient Registration

Patients obtain a recommendation from a licensed physician. While not required to use medical cannabis, obtaining an MMIC through the county health department grants an exemption from the state sales and use tax.

Medical vs Recreational Differences

• Exemption from applicable sales and use tax on qualifying medicinal purchases with a valid MMIC
• Medical possession rules can allow greater quantities than adult-use rules; follow the applicable patient limits and physician recommendation
• Different medical cultivation protections may apply; a recommendation does not override every local or property restriction

Registered medical patients aged 18 and older may access dispensaries, whereas recreational users must be 21.

Is CBD Legal in California?

CBD is legal in California, but the state has implemented some of the nation’s strictest purity requirements for hemp-derived products sold outside licensed dispensaries.

Hemp-Derived CBD

Under CDPH guidance for AB 8 (2025), hemp extract used in food, beverages, supplements, and processed pet food cannot contain THC or synthetic cannabinoids. Testing must establish greater than 99% CBD or CBN purity in the extract. This is an extract requirement, not a claim that a finished drink or gummy is 99% CBD.

Cannabis-Derived CBD

Cannabis-derived CBD products are sold through the licensed cannabis system. Hemp rules depend on product type: CDPH allows extract used in topically applied cosmetics to contain up to 0.3% total THC by dry weight, subject to the applicable manufacturing requirements. Thus, a blanket statement that every CBD product with detectable THC must be sold in a dispensary is inaccurate.

CBD Food and Beverage Laws

Hemp foods and drinks intended for human consumption must meet the no-detectable-THC requirement; the general 0.3% hemp threshold is not sufficient. In-state sales of inhalable hemp products are prohibited. A product’s availability on a website does not prove compliance with California requirements.

Where to Buy Cannabis in California

Licensed Cannabis Dispensaries

California has hundreds of licensed retail stores. Consumers can buy:

• Cannabis flower and pre-rolls
• Concentrates, resin, and shatter
• Edibles and THC-infused beverages
• Vape cartridges
• Tinctures and topicals

Online Ordering and Pickup

Online ordering for in-store pickup or home delivery is widely available in California. Delivery services are permitted to operate even in jurisdictions that have banned physical retail storefronts.

Cannabis Taxes

The CDTFA cannabis excise tax rate is 15% of retail gross receipts, effective October 1, 2025, following a temporary 19% rate that July–September. AB 564 delays the next rate adjustment until fiscal year 2028–2029. Applicable sales and local taxes vary by location; qualifying medicinal sales with an MMIC are exempt from sales and use tax, but not automatically from the cannabis excise tax.

Cannabis Penalties and Restrictions

• Unauthorized adult possession above 28.5 grams of flower or 8 grams of concentrate can carry up to six months in county jail, a fine up to $500, or both; medical and other lawful exceptions matter.
• Public smoking or ingestion is generally an infraction with a fine up to $100. Smoking where prohibited and certain open-container violations can carry a fine up to $250 under the Health and Safety Code.
• Driving while impaired is illegal, and vehicle-specific rules also apply.
• School-ground restrictions and penalties depend on age, location, and circumstances.

Future Cannabis Legislation in California

SB 378 was enacted in October 2025 and its marketplace provisions became operative July 1, 2026. It requires licensing-policy disclosures and reporting mechanisms; marketplaces that do not verify seller licenses must display a warning. It also addresses unlawful paid advertising and liability. These are current requirements, not merely a future proposal. Some AB 8 hemp-regulation changes are scheduled for January 1, 2028.

Summary of Cannabis Laws in California

California remains the benchmark for cannabis legalization, offering broad access and strong consumer protections. While the state has high taxes and complex local regulations, the availability of legal delivery and home cultivation provides significant freedom for residents. The primary shift involves the integration of the hemp and cannabis markets, ensuring that “intoxicating” products are properly taxed and age-gated. Consumers should always check local ordinances, as rules regarding consumption and retail can vary significantly between cities like Los Angeles, San Francisco, and San Diego.
