Kansas has no medical marijuana program. Kansas medical marijuana laws do not exist in any functional sense: the state has no patient registry, no dispensaries, no physician authorization process, and no recognition of medical cards issued elsewhere. Marijuana remains a Schedule I controlled substance under Kansas law, and possessing it for medical reasons carries the same criminal penalties as possessing it for any other reason.1Kansas Office of Revisor of Statutes. Kansas Code 65-4105 – Substances Included in Schedule I The only narrow exception involves certain low-THC CBD oil, and even that is an affirmative defense rather than legal permission.
The One Narrow Exception: Claire and Lola’s Law
In 2019, Kansas enacted Claire and Lola’s Law, which created an affirmative defense for possessing CBD oil containing no more than 5% THC relative to its CBD concentration. The product must be verified by independent lab testing. The law also prevents child-welfare agencies from initiating removal proceedings based solely on a parent’s use of qualifying CBD oil.
An affirmative defense is not legalization. It does not stop an arrest and it does not stop a prosecution. It gives the defendant a legal argument to raise at trial that, if the court accepts it, prevents a conviction. Someone carrying qualifying oil can still be stopped, arrested, and taken to court before ever reaching the point of raising the defense. The law also does nothing to authorize the sale or production of qualifying oils inside Kansas, so sourcing a product that actually meets the statutory requirements is itself a hurdle.
Outside that narrow window, the law treats marijuana use the same whether it is for chronic pain, epilepsy, chemotherapy side effects, or anything else.
Penalties for Possession
Kansas penalizes simple marijuana possession based on prior convictions rather than the quantity involved:2Kansas Office of Revisor of Statutes. Kansas Code 21-5706 – Unlawful Possession of Controlled Substances
- First offense: Class B nonperson misdemeanor, up to six months in jail and a fine of up to $1,000.
- Second offense (one prior): Class A nonperson misdemeanor, up to one year in jail and a fine of up to $2,500.
- Third or subsequent offense (two or more priors): drug severity level 5 felony, carrying potential prison time under the Kansas sentencing guidelines.
Even residue inside a pipe or container counts as possession. Paraphernalia such as pipes, rolling papers, or bongs connected to marijuana use is a separate Class B nonperson misdemeanor, so a single stop that turns up a small amount and a pipe can produce two criminal counts rather than one.3Kansas Office of Revisor of Statutes. Kansas Code 21-5709 – Unlawful Acts Involving Drug Paraphernalia
Out-of-State Medical Cards Don’t Help
Kansas sits between Missouri and Colorado, both of which have legal cannabis. Nearly 2,200 Kansas residents hold Missouri medical marijuana cards, and many more make trips to Colorado. None of it carries any legal weight once the state line is crossed.
Kansas does not recognize medical marijuana authorizations from any other state. A Missouri card, a Colorado card, or a recommendation from a physician in a legal state provides zero protection in Kansas. Bringing marijuana back across the border exposes the driver to the same possession penalties as any other Kansas resident, and it also violates federal law, because transporting a Schedule I substance across state lines is a separate federal offense regardless of what either state allows.
Border enforcement is aware of the pattern. Officers may seize a vehicle on suspicion of distribution, and any sign of impairment can produce an additional DUI charge on top of possession. A small amount, or detectable residue, is enough to support a criminal charge.
Doctors Can’t Recommend It
Kansas physicians cannot recommend, authorize, or help patients obtain marijuana without risking their medical licenses and potential criminal liability. There is no legal framework for a doctor-patient conversation that ends in a cannabis authorization.4Kansas Legislative Research Department. Medical Marijuana Update 2025
In practice, many Kansas physicians avoid the subject rather than appear to facilitate illegal conduct. Patients who use marijuana sourced from other states and disclose that use to a Kansas provider may run into complications with their medical records and care planning.
Employers Don’t Have to Accommodate You
Because there is no state medical marijuana law, Kansas employers face no obligation to accommodate marijuana use for any reason. An employer can keep a zero-tolerance drug policy, require drug testing, and fire or discipline any employee who tests positive for THC. There is no exception for off-duty use, for marijuana purchased legally in another state, or for a physician’s recommendation issued elsewhere.
Even the medical cannabis bills that have been proposed in Kansas have included language explicitly preserving employer rights. The drafts have stated that nothing in a future medical cannabis law would require employers to permit use in the workplace, prevent enforcement of drug-free workplace policies, or stop employers from disciplining employees who use cannabis. If and when Kansas legalizes medical marijuana, workplace protections are unlikely to be strong.
Hemp CBD and Delta-8: A Murky Alternative
Federal law legalized industrial hemp containing no more than 0.3% delta-9 THC by dry weight, and Kansas follows the same threshold.1Kansas Office of Revisor of Statutes. Kansas Code 65-4105 – Substances Included in Schedule I Hemp-derived CBD products that stay inside that limit are generally legal to possess and sell in Kansas.
Delta-8 THC is a different story. A 2021 Kansas Attorney General opinion concluded that delta-8 THC is a Schedule I controlled substance unless it is derived from industrial hemp and contains no more than 0.3% total tetrahydrocannabinols. Most commercially available delta-8 products are concentrated well beyond that threshold and therefore fall outside the exception in practice. Some Kansas county prosecutors have pursued distribution charges against retailers selling delta-8 products, while others have focused enforcement elsewhere. The legal risk of buying or selling concentrated delta-8 products in Kansas is real.
Federal lawmakers are also weighing tighter rules on hemp-derived THC products. A proposed federal rule would redefine legal hemp to limit any form of THC, not just delta-9, and cap total THC per container at very low levels. If adopted, it would further narrow what hemp-derived products are available in Kansas.
What’s Pending in the Legislature
Kansas has come closer to medical marijuana legalization than many residents realize. The Kansas House passed a medical cannabis bill for the first time in 2021 and passed another version in 2023. Both times, the Senate failed to advance the legislation out of committee.4Kansas Legislative Research Department. Medical Marijuana Update 2025
Additional bills followed in 2024, including SB 555 and SB 558, both of which died in the Senate Committee on Federal and State Affairs. In the 2025-2026 session, SB 294 was introduced to enact the Kansas Medical Cannabis Act, which would authorize the cultivation, processing, distribution, sale, and use of medical cannabis.5LegiScan. KS SB294 2025-2026 Regular Session As of early 2025, SB 294 had been referred to the same Senate committee where previous bills have stalled. The House has repeatedly shown willingness to move; the Senate has been the consistent bottleneck.
Federal Rescheduling Would Not Change Kansas Law on Its Own
In May 2024, the Department of Justice proposed reclassifying marijuana from Schedule I to Schedule III, which would acknowledge accepted medical uses while keeping it a controlled substance. The proposal drew nearly 43,000 public comments and is awaiting an administrative law hearing. In December 2025, a presidential executive order directed the Attorney General to complete the rescheduling process as expeditiously as possible.6The White House. Increasing Medical Marijuana and Cannabidiol Research
Federal rescheduling would not automatically legalize medical marijuana in Kansas. State law operates independently, and Kansas would still need its own legislation to establish a medical program. Rescheduling could ease banking, research, and tax issues that have affected cannabis businesses in states with legal programs, and it could reduce some of the political arguments Kansas senators have used to delay action. Until Kansas passes its own law, however, the answer for patients inside the state will stay the same: no legal medical marijuana, and criminal penalties for possession.
