No. Marijuana is illegal in Kansas for both recreational and medical use, and a first possession conviction is a Class B misdemeanor carrying up to 6 months in jail and a $1,000 fine. Kansas allows CBD and offers only a narrow legal defense for patients using CBD oil with limited THC, and the 2026 medical cannabis bill died without a vote.

Kansas sits between Colorado and Missouri, where adults can buy cannabis in licensed stores, and Oklahoma, which runs a large medical program. None of that changes Kansas law. This guide explains the rules as of October 2026, with links to the Kansas statutes behind each one. It is general information, not legal advice.

Is Marijuana Legal in Kansas?

No. Marijuana is listed as a Schedule I hallucinogenic substance in K.S.A. 65-4105, and Kansas has no medical marijuana program, no adult-use law and no statewide decriminalization. Any change would have to come through the Legislature. Medical bills have been filed there for years, including Sen. David Haley’s SB 9 in 2015, and every one has failed.

Cannabis is also illegal under federal law for adult use. Since April 2026, federal Schedule III status applies only to marijuana held under a state medical marijuana license and to FDA-approved products. Kansas issues no such licenses. See our guide to federal marijuana law in 2026.

Possession Penalties in Kansas

Under K.S.A. 21-5706(c)(3), possessing any amount of marijuana or THC is a crime, and the penalty rises with prior convictions:

  • First conviction: Class B nonperson misdemeanor, up to 6 months in county jail and a fine of up to $1,000.
  • Second conviction: Class A nonperson misdemeanor, up to 1 year in county jail and a fine of up to $2,500.
  • Third or later conviction: drug severity level 5 felony, with a fine of up to $100,000.

The jail limits come from K.S.A. 21-6602 and the fines from K.S.A. 21-6611. There is no minimum amount.

Paraphernalia is charged separately. Under K.S.A. 21-5709, possessing paraphernalia to smoke or ingest a controlled substance is a Class B nonperson misdemeanor.

Growing and Selling Marijuana in Kansas

Kansas has no legal home grow. Using equipment to grow fewer than five plants is a Class B misdemeanor under K.S.A. 21-5709. Larger grows are felonies under K.S.A. 21-5705:

  • 5 to 49 plants: drug severity level 3 felony
  • 50 to 99 plants: drug severity level 2 felony
  • 100 or more plants: drug severity level 1 felony

Distribution, or possession with intent to distribute, is a felony at any amount. Less than 25 grams is a drug severity level 4 felony, and the level rises at 25 grams, 450 grams and 30 kilograms.

Medical Marijuana and CBD in Kansas

Kansas has no medical marijuana program, and medical cards from other states have no legal effect there. Two narrower rules matter:

  • CBD is not marijuana. The definition of marijuana in K.S.A. 21-5701 excludes cannabidiol and industrial hemp, so hemp-derived CBD products can be sold and possessed.
  • A defense for CBD oil with some THC. Under K.S.A. 21-5706(d), a person has an affirmative defense to possession if they have a debilitating medical condition and are using a “cannabidiol treatment preparation” to treat it. Under K.S.A. 65-6235, that is an oil with a THC concentration of no more than 5% relative to its CBD, verified by an independent lab. The person must carry a letter on the physician’s letterhead, signed by a Kansas-licensed physician and dated within the past 15 months, that names the patient and condition, and show it to police on request. Parents and guardians of minor patients are covered too.

An affirmative defense is not legalization. It is raised in court after an arrest or charge, and it does not create stores, cards or a supply chain.

Delta-8, THCA and Hemp Products

Kansas excludes industrial hemp and hemp products from its THC listing in K.S.A. 65-4105(h), but it also bans several hemp product forms outright. Under K.S.A. 2-3908, it is unlawful to make, sell or distribute hemp cigarettes, hemp cigars, chew or dip containing hemp, hemp teas, and hemp liquids or solids for vaping. Hemp buds and ground flower may be sold only to registered or licensed processors. A first violation is a Class A nonperson misdemeanor.

Federal law tightens the rules further:

  • November 12, 2026: The federal hemp redefinition in H.R. 5371 removes products with cannabinoids the plant cannot naturally produce, such as THC-O, from the definition of hemp. HHC may also be affected.
  • December 11, 2026: The exclusion of converted cannabinoids such as delta-8 made from CBD, a total-THC standard and a cap of 0.4 mg total THC per container take effect for products with naturally occurring cannabinoids, after H.R. 6500 delayed them. THCA counts toward total THC.

Driving and Cannabis in Kansas

Kansas DUI law under K.S.A. 8-1567 covers driving under the influence of any drug to a degree that makes a person incapable of safely driving. There is no numeric THC limit in the statute, so charges rest on evidence of impairment. Being legally entitled to use a drug is not a defense.

Crossing State Lines and Federal Land

Cannabis bought legally in Colorado or Missouri becomes illegal possession once it enters Kansas, and crossing a state line with it violates federal law. An Oklahoma medical card does not protect a patient in Kansas. TSA refers cannabis found at airport screening to police, and cannabis is illegal on federal land and military installations such as Fort Riley and Fort Leavenworth regardless of state law.

What Changed in Kansas Cannabis Law Recently

  • Medical cannabis (2026): HB 2678, the Kansas medical cannabis act, was introduced in the 2026 session and died without leaving the introduction stage.
  • Rescheduling bill (2026): SB 484, which would have moved marijuana from Schedule I to Schedule III under state law, did not become law.
  • Federal rescheduling (2026): The April 2026 federal order covers only state-licensed medical marijuana and FDA-approved products, so it does not change anything for Kansans.

From the editor, James Buddsey: The most common Kansas mistake is the drive home from Colorado or Missouri with a legal purchase in the trunk. A receipt from a licensed store means nothing on I-70 once you cross the line. A third possession conviction in Kansas is a felony, so even small amounts add up over time.
