California, USA hemp laws: quick overview

California defines “industrial hemp” as Cannabis sativa L. with total THC (Δ9 + THCA) ≤ 0.3% on a dry‑weight basis, per Health and Safety Code §11018.5(a)(2), effective January 1 2026; total THC is calculated as Δ9 + THCA ± measurement uncertainty ([leginfo.legislature.ca.gov](https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=202520260AB8&utm_source=openai)). AB‑8 (Chapter 248, Statutes of 2025), signed October 2 2025, effective January 1 2026 (with some provisions effective January 1 2028), prohibits industrial hemp raw extract in foods, beverages, dietary supplements unless purity > 99% and contains no THC or synthetic cannabinoids; and bans inhalable hemp products, hemp flower, and prerolls ([leginfo.legislature.ca.gov](https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=202520260AB8&utm_source=openai)). CDPH emergency regulations (DPH‑24‑005), adopted September 24 2024 and readopted March 24 2025, prohibit sale of industrial hemp products intended for human use that contain any detectable total THC or other intoxicating cannabinoids ([abc.ca.gov](https://www.abc.ca.gov/enforcement/illegal-hemp-enforcement/?utm_source=openai)).

Shipping guidance

Inbound shipments of industrial hemp (meeting ≤ 0.3% total THC) are allowed if not entering the licensed cannabis market; shipments through California without sale are permitted. Retail of intoxicating hemp products must occur only through licensed cannabis dispensaries under AB‑8. Age verification (21+) applies under cannabis framework. No separate hemp retailer license; manufacturers need IHEOA from CDPH ([leginfo.legislature.ca.gov](https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=202520260AB8&utm_source=openai)).

Testing & COA guidance

Testing by licensed cannabis testing laboratories is required upon entry into the licensed market to confirm industrial hemp meets definition (HSC §26100(b), effective Jan 1 2026). COA must include quantitative analysis showing CBD or CBN > 99% of total chromatographic peaks for hemp extracts used in foods/beverages (AB‑8 FAQ). ISO/IEC 17025 accreditation not explicitly stated; follow licensed lab standards ([leginfo.legislature.ca.gov](https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=202520260AB8&utm_source=openai)).

What to buy

Non‑intoxicating hemp products: CBD or CBN isolates (> 99% purity) without THC or synthetic cannabinoids, for use in foods, beverages, dietary supplements, cosmetics (post‑Jan 1 2026). Industrial hemp seeds, fiber, oil from seeds, and non‑cannabinoid preparations remain legal.

What to avoid

Avoid any hemp products containing Δ8, Δ9, Δ10, THCA, or synthetic cannabinoids—even if derived from hemp—as these are banned in hemp products and must be sold only via licensed cannabis. Hemp flower and prerolls are prohibited. Intoxicating hemp edibles are banned under CDPH emergency regs.
