This guide provides educational, state‑specific information on Kansas hemp and hemp‑derived cannabinoid laws as of September 1, 2026. It is for educational purposes only and not legal advice.

Kansas hemp laws: quick overview

Kansas law defines “industrial hemp” as Cannabis sativa L. containing a delta‑9 THC concentration of not more than 0.3% on a dry weight basis (K.S.A. 2‑3901, effective July 1, 2024) ([ksrevisor.gov](https://ksrevisor.gov/statutes/chapters/ch02/002_039_0001.html?utm_source=openai)). “Final hemp products” may contain tetrahydrocannabinol (all isomers) up to 0.3% by weight ([ksrevisor.gov](https://ksrevisor.gov/statutes/chapters/ch02/002_039_0001.html?utm_source=openai)). Delta‑8 THC is considered a Schedule I controlled substance in Kansas unless derived from industrial hemp and contained in a lawful hemp product with ≤ 0.3% total THC; prohibited forms include cigarettes, cigars, teas, and vaping products (Attorney General Opinion 2021‑4, December 2, 2021) ([firemarshal.ks.gov](https://www.firemarshal.ks.gov/DocumentCenter/View/1069/AGO-2021-4--Regarding-Agriculture---Industrial-Hemp---Commercial-Industrial-Hemp-Act-PDF?utm_source=openai)). Producers must be licensed under USDA’s Domestic Hemp Production Program and processors must register with the State Fire Marshal (KDA guidance, 2026) ([agriculture.ks.gov](https://www.agriculture.ks.gov/licenses/plant-and-seed-licensing-information/industrial-hemp?utm_source=openai)). Testing must use post‑decarboxylation or similarly reliable methods to measure delta‑9 THC (K.S.A. 2‑3906, effective July 1, 2024) ([ksrevisor.gov](https://ksrevisor.gov/statutes/chapters/ch02/002_039_0006.html?utm_source=openai)). Hemp exceeding 0.3% THC must be remediated or disposed of under K.A.R. 4‑34‑25 (regulations) ([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 if the sender is a licensed producer or registered processor. Transport between producers and processors is permitted without additional license, subject to State Fire Marshal rules (K.S.A. 2‑3908) ([ksrevisor.gov](https://ksrevisor.gov/statutes/chapters/ch02/002_039_0008.html?utm_source=openai)). No specific age verification rules are codified yet; SB 292 (2025) proposes prohibiting transfer to persons under 21, but not yet law ([kslegislature.gov](https://kslegislature.gov/b2025_26/documents/view-leg/?apn=b2025_26%2Fyear2%2Fready_for_publication%2Fsb_292%2Fsb292_00_0000.pdf&utm_source=openai)). Retailer registration is required only for processors; no separate retailer license is specified.

Testing & COA guidance

Testing must use post‑decarboxylation or similarly reliable methods to determine delta‑9 THC concentration (K.S.A. 2‑3906) ([ksrevisor.gov](https://ksrevisor.gov/statutes/chapters/ch02/002_039_0006.html?utm_source=openai)). Labs must be certified by USDA or recognized under USDA’s program (per KDA guidance) ([agriculture.ks.gov](https://www.agriculture.ks.gov/licenses/plant-and-seed-licensing-information/industrial-hemp?utm_source=openai)). COA retention requirements are not explicitly stated in statute; null.

What to buy

State‑legal products include hemp‑derived cannabinoid products (e.g. CBD, delta‑8, delta‑9) so long as total THC ≤ 0.3% by dry weight and not in prohibited forms; non‑intoxicating forms like oils, edibles, topicals are acceptable.

What to avoid

Avoid cigarettes, cigars, teas, and vaping products containing hemp (K.S.A. 2‑3908) ([ksrevisor.gov](https://ksrevisor.gov/statutes/chapters/ch02/002_039_0008.html?utm_source=openai)). Any product exceeding 0.3% total THC is unlawful. Delta‑8 from non‑hemp sources is banned.
