Kansas hemp laws: quick overview

Kansas law defines “industrial hemp” as Cannabis sativa L. containing no more than 0.3% delta‑9 THC on a dry‑weight basis (K.S.A. 2‑3901(7), effective July 1, 2024) ([ksrevisor.gov](https://ksrevisor.gov/statutes/chapters/ch02/002_039_0001.html?utm_source=openai)). “Hemp products” may contain up to 0.3% THC; extracts above that threshold may only be marketed by licensed hemp producers or processors (K.S.A. 2‑3908(b)(1)(D), effective April 29, 2021) ([ksrevisor.gov](https://ksrevisor.gov/statutes/chapters/ch02/002_039_0008.html?utm_source=openai)). Kansas prohibits certain hemp products regardless of THC content, including cigarettes, cigars, chew, teas, and vaporizing liquids (K.S.A. 2‑3908(a)(1)(A)–(E), effective April 29, 2021) ([ksrevisor.gov](https://ksrevisor.gov/statutes/chapters/ch02/002_039_0008.html?utm_source=openai)). Delta‑8 THC is classified as a Schedule I controlled substance unless derived from industrial hemp containing no more than 0.3% total THC and included in a lawful hemp product; even then, many product forms remain unlawful (Attorney General Opinion 2021‑4, December 2, 2021) ([sos.ks.gov](https://sos.ks.gov/publications/Register/Volume-41/PDF/Vol-41-No-09-March-3-2022.pdf?utm_source=openai)). Producers must submit pre‑harvest samples no more than 30 days before harvest; hemp cannot be harvested until testing confirms delta‑9 THC <0.3% (K.A.R. 4‑34‑24, effective January 8, 2021, amended December 17, 2021) ([law.cornell.edu](https://www.law.cornell.edu/regulations/kansas/K-A-R-4-34-24?utm_source=openai)). Hemp testing failures (>0.3%) trigger remediation or disposal protocols; remediation allowed up to 2.0% THC under approved plan; >2.0% must be disposed (K.A.R. 4‑34‑25) ([law.cornell.edu](https://www.law.cornell.edu/regulations/kansas/K-A-R-4-34-25?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products are allowed only if they comply with Kansas hemp definitions and THC limits. Transport between licensed producers and processors is permitted without additional registration (K.S.A. 2‑3908(b)(2)). No specific age‑verification rules are defined in state law.

Testing & COA guidance

Kansas requires pre‑harvest sampling by the Department of Agriculture; private lab tests are not official (K.A.R. 4‑34‑24). Testing must use post‑decarboxylation or similarly reliable methods. Certificates of analysis are required for compliance; remediation testing and COA retention implied by regulation. ISO 17025 accreditation is not specified.

What to buy

Allowed products include hemp-derived goods with ≤0.3% delta‑9 THC, such as fiber, seed oil, non‑ingestible extracts, and other non‑prohibited forms produced by licensed hemp producers/processors.

What to avoid

Avoid smokable hemp (buds, floral, leaf material), hemp cigarettes, cigars, teas, vape liquids, and any ingestible hemp products prohibited under the Food, Drug & Cosmetic Act or Commercial Feeding Stuffs Act. Delta‑8 THC products are illegal unless derived from hemp ≤0.3% THC and in lawful form.

How to shop compliant, tested hemp

• Delta‑9 THC in hemp must not exceed 0.3% dry weight (K.S.A. 2‑3901)
• Extracts >0.3% Δ9‑THC may only be sold by licensed producers/processors (K.S.A. 2‑3908)
• Certain hemp products (e.g., smokables, teas, vape liquids) are prohibited (K.S.A. 2‑3908)
• Delta‑8 THC is Schedule I unless derived from hemp ≤0.3% total THC (AG Opinion 2021‑4)
• Pre‑harvest sampling and testing required; cannot harvest until <0.3% Δ9‑THC confirmed (K.A.R. 4‑34‑24)
• Remediation/disposal required for hemp >0.3% Δ9‑THC (K.A.R. 4‑34‑25)
