California, USA hemp laws: quick overview

California defines “industrial hemp” as Cannabis sativa L. with total THC (Δ9 + THCA) no more than 0.3% on a dry‑weight basis, per Health & Safety Code § 11018.5, amended by AB 8 (Stats. 2025, Ch. 248), effective January 1 2026 ([law.justia.com](https://law.justia.com/codes/california/code-hsc/division-10/chapter-1/section-11018-5/?utm_source=openai)). Total THC includes Δ9‑THC and THCA, calculated per CDFA rules ([law.justia.com](https://law.justia.com/codes/california/code-hsc/division-10/chapter-1/section-11018-5/?utm_source=openai)). The sale or delivery of hemp flower and hemp prerolls is explicitly prohibited under § 11018.5(c) ([law.justia.com](https://law.justia.com/codes/california/code-hsc/division-10/chapter-1/section-11018-5/?utm_source=openai)). Assembly Bill 45 (2021) amended the Sherman Food, Drug, and Cosmetic Law to allow hemp‑derived cannabinoids (e.g., CBD) in foods, beverages, dietary supplements, cosmetics, and pet food, provided total THC ≤ 0.3% and products meet testing and labeling requirements ([legalclarity.org](https://legalclarity.org/ab-45-californias-law-on-hemp-and-cbd-products/?utm_source=openai)). AB 8 (2025) further restricts intoxicating hemp‑derived cannabinoids (Δ8, Δ10, etc.), limiting their sale to licensed cannabis dispensaries ([allowedhere.com](https://allowedhere.com/legality/delta-8-thc/california/?utm_source=openai)). Emergency regulations adopted by CDPH require that industrial hemp final‑form food products have no detectable THC per serving, be sold only to persons 21+, and contain no more than five servings per package ([cdph.ca.gov](https://www.cdph.ca.gov/Programs/OLS/Pages/DPH-24-005E-Emergency-Regulations-for-Industrial-Hemp.aspx?utm_source=openai)).

Shipping guidance

Inbound shipments of compliant hemp (≤ 0.3% total THC) are allowed. Hemp flower and prerolls cannot be sold or delivered. Intoxicating hemp‑derived cannabinoids (Δ8, Δ10, etc.) may only be shipped to licensed cannabis dispensaries; unlicensed retail shipments are prohibited.

Testing & COA guidance

Testing is required pre‑harvest by CDFA‑approved labs, measuring total THC (Δ9 + THCA) with uncertainty applied per 3 CCR § 4890 and § 4944; USDA‑certified samplers must collect samples per 3 CCR § 4941 ([cdfa.ca.gov](https://www.cdfa.ca.gov/plant/industrialhemp/faq.html?utm_source=openai)). Finished hemp‑derived consumables must include COA and meet “no detectable THC per serving” standard ([cdph.ca.gov](https://www.cdph.ca.gov/Programs/OLS/Pages/DPH-24-005E-Emergency-Regulations-for-Industrial-Hemp.aspx?utm_source=openai)).

What to buy

Non‑intoxicating hemp‑derived products (e.g., CBD in food, beverages, supplements, cosmetics, pet food) with total THC ≤ 0.3%, sold with COA and compliant labeling, to persons 21+.

What to avoid

Hemp flower and prerolls (banned); intoxicating hemp‑derived cannabinoids (Δ8, Δ10, THCA‑rich products) sold outside licensed cannabis dispensaries; any hemp consumable with detectable THC per serving.
