Understanding Cannabis Law in California

California's cannabis legal landscape is one of the most complex regulatory frameworks in the country. Since voters approved Proposition 64 in 2016, adults 21 and older have been permitted to use, possess, and cultivate limited amounts of marijuana for personal use. But the commercial cannabis industry operates under a dense web of state and local regulations that govern every aspect of the business — from licensing and cultivation to testing, distribution, and retail sales. At the same time, cannabis remains a Schedule I controlled substance under federal law, creating a persistent tension that affects banking, taxation, and interstate commerce.

Whether you are an entrepreneur seeking a cannabis license, an existing operator navigating compliance, or an individual facing cannabis-related criminal charges in San Jose, San Francisco, Oakland, Santa Cruz, or anywhere in Alameda County or San Francisco County, the attorneys at RV Litigation Group PC can help. We handle licensing, regulatory compliance, criminal defense, tax disputes, and business formation matters across the cannabis industry.

What the Law Says

Health & Safety Code 11362.1 — Adult Use

"Subject to the provisions of this section and in accordance with the provisions of law, it shall be lawful under state and local law for persons 21 years of age or older to... possess, process, transport, purchase, obtain, or give away to persons 21 years of age or older without any compensation whatsoever, not more than 28.5 grams of cannabis not in the form of concentrated cannabis... [and] possess, plant, cultivate, harvest, dry, or process not more than six living cannabis plants." — California Health & Safety Code Section 11362.1

Proposition 64, codified in the Adult Use of Marijuana Act (AUMA), established the baseline for personal cannabis use in California. Adults 21 and older may possess up to 28.5 grams of flower or 8 grams of concentrate, cultivate up to six plants per residence, and consume cannabis in private residences (though landlords may prohibit use on their property). Public consumption remains illegal, and driving under the influence of cannabis is prosecuted under Vehicle Code 23152(f). While Prop 64 decriminalized personal use, it also created the regulatory framework for commercial operations that would later be refined through MAUCRSA.

Business & Professions Code 26000+ — MAUCRSA

"The Medicinal and Adult-Use Cannabis Regulation and Safety Act establishes a comprehensive system to control and regulate the cultivation, distribution, transport, storage, manufacturing, processing, and sale of both medicinal and adult-use cannabis and cannabis products." — California Business & Professions Code Section 26000 (MAUCRSA)

MAUCRSA — the Medicinal and Adult-Use Cannabis Regulation and Safety Act — unified California's previously separate medical and adult-use cannabis regulatory frameworks into a single system administered by the Department of Cannabis Control (DCC). The law establishes license types for every segment of the supply chain: cultivation, manufacturing, distribution, testing, retail, microbusiness, and delivery. Each license type has specific requirements regarding premises, security, record-keeping, track-and-trace compliance (METRC), and employee training. Critically, MAUCRSA operates on a dual-licensing model — operators must obtain both a local permit and a state license before they can legally conduct commercial cannabis activity.

Revenue & Tax Code — Cannabis Taxation

California imposes multiple layers of taxation on cannabis businesses. The state levies a cannabis excise tax of 15% on the retail price of cannabis and cannabis products. Local jurisdictions may impose additional taxes — some cities charge between 5% and 15% on gross receipts. Cannabis businesses are also subject to standard state income taxes. At the federal level, IRC Section 280E prohibits cannabis businesses from deducting ordinary business expenses from their federal taxable income, resulting in an effective tax rate that can exceed 70%. This tax burden is one of the most significant challenges facing the legal cannabis industry and makes careful tax planning essential for survival.

Real-World Examples

These scenarios illustrate the types of cannabis law matters we handle throughout the Bay Area:

Example 1 — Dispensary Licensing in San Jose

An entrepreneur in San Jose applies for a retail cannabis license but is denied at the local level due to zoning restrictions that place the proposed location within 1,000 feet of a school. RV Litigation Group PC reviews the zoning ordinance, identifies an alternative compliant location, and guides the applicant through the city permitting process and DCC state license application. The dispensary opens within 14 months of initial engagement.

Example 2 — Unlicensed Distribution in San Francisco

A cannabis delivery service in San Francisco is cited by the DCC for operating without a valid state distribution license. The operator had a local permit but failed to complete the state licensing process. We negotiate with the DCC to resolve the citation, bring the operator into full MAUCRSA compliance, and implement standard operating procedures to prevent future violations. The business avoids license revocation.

Example 3 — Excess Cultivation in Oakland

A home grower in Oakland is cited by local code enforcement for cultivating twelve cannabis plants — double the legal limit of six per residence under HS 11362.2. The excess cultivation results in a misdemeanor charge. We negotiate a plea that avoids jail time and helps the client understand compliance requirements going forward, including the option of applying for a small cultivation license.

Example 4 — Tax Dispute in Santa Cruz

A licensed cultivator in Santa Cruz receives a deficiency notice from the California Department of Tax and Fee Administration (CDTFA) asserting unpaid cannabis excise taxes. The cultivator believed their product was exempt from certain taxes as a medical cannabis product. We review the tax records, negotiate with the CDTFA, and reach a settlement that reduces the assessed liability by 40% while bringing the client into full tax compliance.

What's at Stake

Cannabis law violations — whether criminal, regulatory, or tax-related — carry serious consequences. The penalties depend on whether the conduct involves personal use, commercial activity, or federal law violations.

Violation Potential Penalties Consequences
Unlicensed Sale Up to $30,000/day fines (DCC), misdemeanor/felony charges Business closure, criminal record, asset forfeiture
Excess Cultivation Misdemeanor, up to 6 months jail, $500 fine Criminal record, plant destruction
Tax Evasion Back taxes, penalties, interest; potential criminal prosecution License revocation, business closure
DUI — Cannabis Up to 6 months jail, $1,000 fine, license suspension Criminal record, increased insurance, DUI school
Sale to Minors Felony, up to 7 years state prison License revocation, sex offender registry (if under 14)
Federal Violations Up to 5 years federal prison (first offense, <50 plants) Asset forfeiture, federal criminal record, banking restrictions

Additional consequences: Beyond criminal penalties, cannabis law violations can result in license revocation by the DCC, loss of local permits, tax liens, and civil forfeiture of business assets. For licensed operators, even minor compliance failures — such as track-and-trace reporting errors or labeling violations — can trigger administrative actions that threaten the viability of the business. The federal-state conflict also creates ongoing risks for cannabis businesses regarding banking access, bankruptcy protection, and intellectual property enforcement.

How We Help

Cannabis law requires attorneys who understand both the regulatory framework and the practical realities of operating in this industry. Here is how we serve our clients:

1. License Application Support

Obtaining a cannabis license in California is a multi-step process that requires coordination between local and state agencies. We guide applicants through every phase — from selecting the right license type and identifying compliant locations to preparing the application, financial documents, operating plans, and security protocols required by both the city and the DCC. Our attorneys have experience with license applications in San Jose, San Francisco, Oakland, and other Bay Area jurisdictions, each of which has its own permitting requirements, community engagement processes, and competitive selection criteria.

2. Regulatory Compliance

Once licensed, cannabis operators face ongoing compliance obligations that touch every aspect of their business. We advise on METRC track-and-trace requirements, packaging and labeling regulations, testing protocols, waste disposal, employee background checks, and record-keeping obligations. We conduct compliance audits to identify potential violations before the DCC does, and we represent clients in administrative proceedings when violations are alleged. Staying in compliance is not optional — a single significant violation can result in license suspension or revocation.

3. Local Permitting

Many California cities and counties have their own cannabis ordinances with specific requirements that go beyond state law. Some jurisdictions limit the number of licenses available, require community benefit agreements, impose additional zoning buffers, or mandate equity programs. We navigate these local requirements on behalf of our clients, attend planning commission and city council hearings, respond to community opposition, and ensure that local permits are obtained and maintained. In jurisdictions that have banned commercial cannabis activity, we advise clients on the feasibility of seeking regulatory change.

4. Criminal Defense

Despite legalization, cannabis-related criminal charges remain common in California. Possession of amounts exceeding legal limits, cultivation beyond six plants, unlicensed sales, driving under the influence, and sale to minors all carry criminal penalties. We defend individuals facing these charges in state court, negotiate plea agreements, pursue dismissals where possible, and assist with post-conviction relief for individuals with prior cannabis convictions eligible for resentencing or expungement under Proposition 64. Our criminal defense attorneys understand both the substance of cannabis law and the procedural strategies that produce the best outcomes.

5. Tax Dispute Resolution

Cannabis businesses face a uniquely punishing tax environment. Between state excise taxes, local taxes, standard income taxes, and the federal IRC 280E prohibition on business expense deductions, tax compliance is both complex and costly. We advise cannabis businesses on tax planning strategies, represent clients in disputes with the CDTFA and the IRS, negotiate installment agreements and offers in compromise, and help operators structure their businesses to minimize their overall tax burden within the bounds of the law.

6. Business Formation

Starting a cannabis business requires careful attention to entity structure, ownership, financing, and governance. We help entrepreneurs form LLCs, corporations, and partnerships that comply with DCC ownership disclosure requirements, draft operating agreements that address the unique challenges of the cannabis industry (including cash management and banking limitations), and structure equity arrangements that satisfy both state regulations and investor expectations. We also advise on intellectual property protection, trademark strategies, and commercial lease negotiations for cannabis-specific properties.

Frequently Asked Questions

Under Health & Safety Code 11362.1, adults 21 and older may legally possess up to 28.5 grams (approximately one ounce) of marijuana flower and up to 8 grams of concentrated cannabis. Possession of amounts exceeding these limits without a valid license may result in misdemeanor charges. Medical marijuana patients with a valid recommendation may possess additional amounts as needed for their medical condition.

Yes. Under Health & Safety Code 11362.2, adults 21 and older may cultivate up to six living marijuana plants per residence for personal use. The plants must be grown in a locked space that is not visible from a public place. Local jurisdictions may impose additional restrictions on outdoor cultivation but cannot completely ban indoor growing. Cultivating more than six plants without a license may result in criminal charges.

Opening a dispensary requires both a local permit and a state license. You must first obtain authorization from the city or county where you plan to operate, as many jurisdictions have their own application processes, zoning requirements, and caps on the number of licenses issued. Once you have local approval, you apply to the Department of Cannabis Control (DCC) for a state license under MAUCRSA (B&P Code 26000+). The process involves background checks, facility inspections, and compliance with packaging, testing, and track-and-trace requirements.

Yes. Marijuana remains classified as a Schedule I controlled substance under the federal Controlled Substances Act. While California has legalized marijuana for adult use and medical purposes, federal law still prohibits its cultivation, distribution, and possession. This creates significant legal complications for cannabis businesses, particularly regarding banking, taxation (IRC Section 280E), and interstate commerce. Federal enforcement priorities have varied by administration.

California law (AB 2188, effective January 1, 2024) prohibits most employers from discriminating against employees or applicants based on their off-duty cannabis use. However, employers may still take action based on impairment at work and may maintain drug-free workplace policies. Certain industries — including federal contractors, transportation, and safety-sensitive positions — are exempt. Employers cannot use hair follicle tests that detect non-psychoactive cannabis metabolites as the sole basis for employment decisions.
