Kansas has no medical cannabis program and no adult-use program. Recreational cannabis is illegal, and home cultivation is a criminal offense — with penalties that escalate sharply based on plant count. Hemp cultivation is legal in Kansas, but as of January 1, 2025, Kansas stopped issuing its own hemp producer licenses. Kansas growers must now apply directly to the USDA through the federal Hemp eManagement Platform. What any Kansas resident can legally do right now is purchase cannabis seeds, including high-THC varieties, for collecting and to be prepared if and when Kansas legalizes home cultivation. Cannabis seeds are legally classified as hemp under the 2018 Farm Bill — the seed itself contains no meaningful THC regardless of what the plant would eventually produce. This post covers the current USDA licensing process for Kansas hemp growers, existing cannabis law, and where reform efforts stand.

Can You Grow Cannabis at Home in Kansas?
No. Home cultivation of cannabis is a criminal offense in Kansas at any scale. Kansas law distinguishes between small and larger grows:
Growing one to four plants is treated differently from growing five or more. Possessing paraphernalia used to cultivate four or fewer plants is a Class B nonperson misdemeanor, carrying up to six months in jail and a $1,000 fine. For five or more plants, cultivation becomes a Level 5 drug felony — a substantial escalation. Cultivation of five to fewer than 50 plants is a felony carrying 46 to 83 months in prison and fines up to $300,000. Cultivation of 50 to fewer than 100 plants is a felony carrying 92 to 144 months imprisonment and fines up to $500,000. Cultivation of 100 or more plants carries 138 to 204 months imprisonment and fines up to $500,000.
Kansas also has a marijuana tax stamp law. Persons who possess marijuana are legally required to purchase and affix state-issued tax stamps to the cannabis. Failure to do so is a separate criminal violation in addition to any possession or cultivation charge.
There is no medical cannabis program and no decriminalization in Kansas. All cultivation is criminal at any plant count.
Hemp Is Legal to Grow in Kansas With a USDA License
Hemp — cannabis with no more than 0.3% delta-9 THC by dry weight — is legal to cultivate in Kansas, but the licensing process changed significantly on January 1, 2025. Prior to that date, Kansas growers applied for licenses through the Kansas Department of Agriculture (KDA). Kansas chose not to renew its USDA-approved state hemp plan, and as of January 1, 2025, the U.S. Department of Agriculture now directly administers hemp producer licensing for Kansas growers.
This means Kansas growers apply to the federal USDA Domestic Hemp Production Program — the same program used by growers in states that have never had their own approved plan. The KDA retains an advisory role and maintains a public list of licensed Kansas producers, but licensing, compliance sampling, and reporting all run through the federal program.
Hemp cultivation on land belonging to Kansas tribal nations — including the Prairie Band Potawatomi Nation and the Iowa Tribe of Kansas and Nebraska — is regulated by each respective tribal nation’s regulatory authority, not USDA.
How to Get a USDA Hemp Producer License in Kansas
All Kansas hemp producer license applications are submitted through USDA’s Hemp eManagement Platform (HeMP) at hemp.ams.usda.gov.
- Create a Login.gov or USDA eAuthentication (eAuth) account at eauth.usda.gov.
- Log in to the HeMP platform at hemp.ams.usda.gov and create your producer account.
- Submit a USDA Hemp Application through HeMP, providing the address and GPS coordinates of each production site, the acreage or square footage for each lot, and a description of your growing operation.
- Complete the FBI Identity History Summary (criminal background check). The FBI provides instructions through the HeMP application process. This requires fingerprinting.
- Register your growing location with your local USDA Farm Service Agency (FSA) office and report your acreage each growing season.
- Before harvest, select a USDA-certified sampling agent from the official USDA directory to collect compliance samples, and select a DEA-registered testing laboratory to receive those samples.
The USDA does not charge a license fee. You can reach the USDA Domestic Hemp Production Program at farmbill.hemp@usda.gov or (888) 721-4367 with questions. For Kansas-specific information, the KDA industrial hemp page at agriculture.ks.gov/industrialhemp provides updates and information about the transition.
What the License Requires
Under the USDA program, Kansas hemp growers must meet federal compliance requirements:
Pre-harvest sampling. A USDA-certified sampling agent must collect compliance samples from your lot within 30 days of your anticipated harvest date. All results are reported through HeMP. Do not harvest before receiving your results.
Acreage reporting. Annual crop acreage reports must be submitted to your local USDA Farm Service Agency office.
Sampling agent and lab costs. You pay the USDA-certified sampling agent and the DEA-registered testing laboratory directly. These are the primary ongoing compliance costs under the USDA program.
Annual reporting. Production reports covering acreage planted, acreage harvested, and yield are submitted through HeMP annually.
Non-compliant crops. If your crop tests above 0.3% delta-9 THC, it is classified as marijuana under federal and Kansas law and must be destroyed. First negligent violations do not carry criminal penalties; repeated or intentional violations can result in license revocation and federal referral.
What Is Changing: Kansas Cannabis Legislation in 2025 and 2026
Kansas has been introducing cannabis reform bills for years without success, and 2026 continued that pattern — though support is growing.
HB 2678 and SB 294 — Medical cannabis bills (dead, 2026 session). Both bills sought to legalize medical cannabis and create a licensed dispensary program in Kansas. HB 2678, introduced in February 2026, was referred to the House Interstate Cooperation Committee in March 2026 but did not advance. SB 294 has been stuck in the Senate Federal and State Affairs Committee since March 2025. Governor Laura Kelly has expressed support for medical cannabis, but Senate Republican leadership has continued to block floor votes.
HB 2405 — Adult-use legalization (dead, 2026 session). Introduced by House Democrats, this bill would have legalized and regulated cannabis for adults 21 and older. It did not receive a committee hearing.
SB 295 — Decriminalization bill. Submitted in March 2025, SB 295 would remove criminal penalties for possession of under one ounce of cannabis flower, five grams of concentrate, and up to 1,000 milligrams of edibles, replacing them with a $25 civil infraction or community service. The bill has not advanced.
Growing legislative pressure. Kansas is now fully surrounded by states with some form of legal cannabis — Missouri to the east has full adult-use sales, Colorado to the west has full adult-use sales, Nebraska to the north passed medical cannabis by ballot initiative in 2024, and Oklahoma to the south has a medical program. An estimated 1,000 or more Kansans hold out-of-state medical cannabis cards, primarily in Missouri. The economic and political pressure on Kansas lawmakers is increasing each session.
Outdoor Growing in Kansas
Kansas spans USDA hardiness zones 5b through 7a, with the western High Plains in zones 5b and 6a and the eastern third of the state reaching zone 6b to 7a. The outdoor growing season runs from mid-May through October in most of the state, with the warmer southeastern counties offering a somewhat longer window.
Kansas’s flat, fertile cropland and long summers are well-suited to commercial fiber hemp and grain hemp production, which has been expanding in the state. Industrial hemp acreage in Kansas grew 97% in 2024 compared to 2023, reflecting real momentum in the state’s hemp industry.
Photoperiod hemp strains typically reach maturity in late September through early October across most of Kansas. Autoflowering hemp strains — finishing in 70 to 90 days regardless of light cycle — can work well for growers in the western counties who want more control over harvest timing given the variability of fall weather on the High Plains.
If you are a licensed hemp grower looking for genetics suited to Kansas’s climate, our USDA zone map tool can help you identify your zone and planting window. We carry CBD seeds for outdoor production, and if you want to be ready for when Kansas’s laws change, you can browse our full seed catalog — including high-THC feminized varieties. The seeds themselves are legally classified as hemp and are legal to purchase and ship to Kansas today.
Penalties for Growing Without a License
Cultivation of cannabis without a license in Kansas carries criminal penalties that escalate significantly with plant count:
Growing one to four plants: possession of paraphernalia used to cultivate four or fewer plants is a Class B nonperson misdemeanor — up to six months in jail and a $1,000 fine. Growing five or more plants crosses into Level 5 drug felony territory. Five to fewer than 50 plants carries 46 to 83 months in prison and fines up to $300,000. Fifty to fewer than 100 plants carries 92 to 144 months in prison and fines up to $500,000. One hundred or more plants carries 138 to 204 months in prison and fines up to $500,000.
Possessing paraphernalia used to cultivate five or more plants is separately a felony carrying five months probation to 17 months imprisonment and fines up to $100,000.
Kansas also requires that marijuana tax stamps be affixed to any cannabis in possession — failure to comply is an additional criminal offense.
Growing hemp without a USDA producer license is illegal under federal law and exposes growers to federal liability.
Frequently Asked Questions

Are CBD products legal in Kansas?
Kansas law exempts CBD products containing zero percent THC from the state’s criminal definition of marijuana, making them legal to possess and sell in accordance with applicable licensing requirements. Hemp-derived products with any detectable THC occupy a gray area under state law, though the federal 0.3% standard applies to cultivation and interstate commerce.
Can I buy cannabis seeds in Kansas?
Yes. Cannabis seeds — including high-THC feminized varieties — are legal to purchase in Kansas. Cannabis seeds are legally classified as hemp under the 2018 Farm Bill — the seed itself contains no meaningful THC regardless of what the plant would eventually produce. Many Kansas residents purchase seeds now for collecting and to be ready if and when the state legalizes home cultivation.
