California Cannabis Regulatory Compliance Attorney
California operates one of the most demanding cannabis and hemp regulatory regimes in the United States. Operators are subject to overlapping state and local rules administered by the Department of Cannabis Control, the California Department of Food and Agriculture, the California Department of Public Health, and dozens of local licensing authorities. Non-compliance can produce license suspension, civil fines, mandatory recalls, and permanent license revocation — consequences that can erase years of investment. The firm provides proactive, ongoing regulatory compliance counsel to retailers, distributors, cultivators, manufacturers, and testing laboratories across California.

California's Cannabis Regulatory Framework
The state’s consolidated cannabis regulations live in Title 4, Division 19 of the California Code of Regulations, administered by the DCC since the agency’s 2021 consolidation under AB 141. Consolidation simplified the state-level picture; it did not simplify the local one. Each of California’s 482 cities and 58 counties retains independent authority over cannabis activity within its jurisdiction, which means compliance for any multi-location operator is necessarily multi-jurisdictional.
Enforcement has intensified. The DCC’s Unified Cannabis Enforcement Task Force has seized hundreds of millions of dollars of unlicensed cannabis products in recent enforcement cycles. The pace and scale of that activity has produced a secondary effect: licensed operators are facing heightened scrutiny, with enforcement teams increasingly examining licensed premises for secondary violations during operations targeting adjacent unlicensed activity.
Hemp regulation has moved equally fast. CDPH Emergency Regulation DPH-24-005 broadly prohibits intoxicating hemp consumables — including products containing delta-8 THC, delta-10 THC, HHC, and THCA — outside the licensed cannabis system. Hemp retailers must source exclusively from CDPH IHEOA-authorized manufacturers and must produce batch-level certificate of analysis documentation on demand. Failures have produced enforcement actions and padlock orders across the state.
Compliance Across the Supply Chain
Compliance obligations differ materially by license type. Cultivators must satisfy CDFA pre-harvest testing (for hemp) and DCC track-and-trace obligations (for cannabis), plus local agricultural and water-use rules. Manufacturers must comply with DCC packaging, labeling, batch testing, and additive restrictions. Distributors must comply with transport manifests, QA testing, and the restrictions on technology-platform profit-sharing structures. Retailers must comply with age verification, advertising restrictions, and DCC inspection record obligations.
Most compliance failures are not the result of operators ignoring the rules — they are the result of operators not realizing a rule has changed, or not realizing a routine operational decision triggers a regulatory consequence. The firm’s compliance counsel is structured to surface those issues before they become enforcement matters.

What Our Clients Say
Testimonials or endorsements do not constitute a guarantee, warranty, or prediction regarding the outcome of your legal matter. Results depend on the specific facts and legal circumstances of each case.
IRC § 280E
Federal scheduling status: State-licensed medical cannabis is now Schedule III under the federal Controlled Substances Act (21 U.S.C. §§ 801 et seq.), removing qualifying medical operators from IRC § 280E. Adult-use/recreational cannabis remains Schedule I and subject to IRC § 280E. Dual-license operators who want to claim IRC § 280E relief on their medical operations must segregate their medical and adult-use supply chains. A broader DEA rescheduling proceeding, to consider moving all forms of marijuana to Schedule III, has not yet yielded a final ruling.
Section 280E of the Internal Revenue Code historically prohibited cannabis businesses from deducting ordinary business expenses, because § 280E applies only to businesses trafficking in Schedule I or II controlled substances. Because state-licensed medical marijuana is now Schedule III, qualifying state-licensed medical cannabis businesses are outside § 280E’s scope. The IRS has confirmed that qualifying businesses may deduct ordinary and necessary business expenses under IRC § 162 for the full 2026 tax year.
Important: Dual-license operators (medical and recreational) will need to apportion expenses between Schedule III and Schedule I activities; IRS guidance on apportionment is pending. Regulatory compliance strategy must account for this bifurcation, licensing structures, reporting obligations, and compliance documentation all interact with a business’s § 280E exposure.

Ongoing Compliance: Two Regulatory Tracks, Two Sets of Rules
Cannabis and industrial hemp operators in California answer to different regulators and face fundamentally different ongoing compliance obligations. Cannabis licensees are regulated by the Department of Cannabis Control and must maintain compliance with a dense web of state requirements: real-time seed-to-sale tracking through the state’s Metrc system, with 24-hour reporting deadlines for inventory discrepancies and transfer manifests, three-day windows for tagging plants and recording harvests, and mandatory 30-day inventory reconciliations. Cannabis licensees must also renew annually, submitting updated financial disclosures, premises diagrams, and evidence of continued local approval — and late renewals trigger a 50% penalty fee. Each license type (cultivation, manufacturing, distribution, retail, testing, microbusiness) layers on its own operational rules around security, packaging, labeling, and transportation.
Industrial hemp operators face a parallel but distinct compliance regime administered by the California Department of Food and Agriculture and enforced at the county level by local agricultural commissioners. Hemp registrations are also annual and must be renewed at least 30 days before expiration; any lapse in registration renders existing crops non-compliant and potentially subject to destruction. Instead of Metrc, hemp growers must comply with CDFA sampling and testing protocols: pre-harvest THC sampling is conducted by or coordinated through the county agricultural commissioner, and if a crop tests above the 0.3% delta-9 THC threshold it fails as California industrial hemp and cannot be sold. Hemp growers can also face a five-year registration ban after three negligent THC violations within five years. The firm helps cannabis and hemp operators understand which compliance framework applies to their operations — and where clients hold both DCC licenses and CDFA hemp registrations, ensures that compliance in one system does not inadvertently create problems in the other.
