Kansas Cannabis Laws: What's Legal and What's Not

Quick Answer: Cannabis Legality in Kansas

Kansas maintains highly restrictive cannabis laws:

• Adult-use (recreational) cannabis: Illegal.
• Medical cannabis program: No comprehensive program exists. Kansas lacks dispensaries, patient registries, and licensed cultivators.
• Hemp-derived CBD products: Legal if derived from hemp and containing less than 0.3% Delta-9 THC on a dry-weight basis, consistent with federal and state law.
• High-CBD/low-THC cannabis preparations: A narrow affirmative defense exists under Kansas Senate Bill 28 (2019) for specific high-CBD/low-THC preparations. This is a courtroom defense, not a permit for free possession or purchase.

Cannabis (marijuana) is a Schedule I controlled substance under K.S.A. Chapter 65, Article 41 (Uniform Controlled Substances Act). Possession of any amount outside the SB 28 affirmative defense is a criminal offense.

Current Legal Status of Cannabis Products in Kansas

Hemp-Derived CBD

Kansas law aligns with the 2018 Farm Bill. Hemp is defined as Cannabis sativa L. with a Delta-9 THC concentration of no more than 0.3% on a dry-weight basis. Products meeting this threshold are agricultural commodities, not controlled substances, under Kansas law. Consult the Kansas Department of Agriculture for current hemp program rules. CBD oils, tinctures, and topicals sold in retail stores qualify if they meet the threshold and are properly tested.

High-CBD/Low-THC Cannabis Preparations Under SB 28

Kansas Senate Bill 28 (2019), known as "Clare and Lola's Law," created a specific affirmative defense for a defined category of cannabis preparation. The law defines a "high-CBD/low-THC cannabis preparation" as a preparation with:

• At least 5% cannabidiol (CBD) by volume, and
• No more than 0.3% tetrahydrocannabinol (THC) by volume

This definition mirrors the hemp THC threshold but adds a minimum CBD floor. Products must meet both criteria to qualify (Kansas Senate Bill 28, 2019).

Delta-8, Delta-10, and Synthetic Cannabinoids

Delta-8 THC and Delta-10 THC exist in a national legal gray zone, and Kansas has not enacted explicit carve-outs. If derived from hemp and containing less than 0.3% Delta-9 THC, a product may technically fall under the hemp exemption. However, Kansas law enforcement and prosecutors have treated synthetically converted cannabinoids with skepticism. The Kansas Attorney General's office has not issued a definitive public opinion on these products. Synthetic cannabinoids (e.g., K2/Spice) are explicitly scheduled under K.S.A. §65-4105. Consult a Kansas attorney before selling or purchasing Delta-8 or Delta-10 products in Kansas.

Medical Cannabis: Limited Provisions, No Comprehensive Program

Kansas lacks a comprehensive medical cannabis program. No dispensaries, cultivation licenses, patient ID cards, or physician certification pathways exist for legal access to cannabis products above SB 28 thresholds.

What SB 28 Actually Does

Kansas Senate Bill 28 (2019) provides two narrow protections:

1. Child protection proceedings. State agencies cannot initiate child removal proceedings or child protective actions based solely on a child's or parent's possession of a qualifying high-CBD/low-THC cannabis preparation.
2. Affirmative defense to criminal prosecution. A person with a debilitating medical condition who possesses a high-CBD/low-THC cannabis preparation (meeting the 5% CBD / 0.3% THC thresholds above) may assert an affirmative defense against criminal charges. The law does not specify an exhaustive list of qualifying debilitating conditions. Consult the Kansas Legislature's official text of SB 28 or a Kansas criminal defense attorney for precise language.

What SB 28 Does Not Do

This law does not:

• Create a licensed dispensary system
• Allow physicians to certify patients for cannabis access
• Permit possession of cannabis products above the defined thresholds
• Protect individuals from federal prosecution

An affirmative defense allows a person to raise it after being charged. It does not provide immunity from arrest or prosecution.

Penalties for Cannabis Offenses in Kansas

Kansas criminal penalties for cannabis offenses are outlined in the Kansas Statutes Annotated (K.S.A.), primarily within the criminal code. The Kansas Sentencing Guidelines govern how judges apply these statutes.

Possession of Marijuana

Penalties for possession of marijuana vary based on the amount and offense history. A first offense is typically a misdemeanor, while subsequent offenses or larger quantities can result in felony charges. Consult the Kansas Statutes and the Kansas Sentencing Guidelines for specific classifications and potential sentences.

Cultivation

Cultivation of marijuana plants is generally treated as manufacturing. Penalties vary significantly based on quantity and criminal history. Consult the Kansas Statutes and the Kansas Sentencing Guidelines for specific classifications and potential sentences.

Distribution or Possession with Intent to Distribute

Distribution or possession with intent to distribute marijuana carries felony penalties, which escalate with quantity and criminal history. Consult the Kansas Statutes and the Kansas Sentencing Guidelines for specific classifications and potential sentences.

Drug Paraphernalia

Possession of drug paraphernalia is a misdemeanor offense. Consult the Kansas Statutes for specific penalties.

Driver's License Consequences

A cannabis conviction can trigger a driver's license suspension. Consult the Kansas Department of Revenue for current suspension schedules and rules.

Recent Legislative Activity and Future Outlook for Cannabis in Kansas

Governor Kelly's Position

Governor Laura Kelly has publicly supported a tightly regulated medical cannabis program, stating: "I do believe that medical marijuana needs to be legalized. It does have medical uses, and I think it would do a lot for our families … and I also think that it would help with the opioid crisis." On adult-use legalization, she has taken a neutral stance, noting: "[Adult-use legalization] is something where what the people want is probably more what I will want on something like that. I don’t have a personal ideology regarding it. If the folks want it and the legislature passes it, would I sign it? Probably." (NORML Kansas summary).

Legislative Landscape

The Republican-controlled Kansas Legislature has historically blocked cannabis reform bills. Medical cannabis bills have been introduced in recent sessions but have stalled in committee. For current bill status, check the Kansas Legislature's official bill tracking system at kslegislature.org.

Federal Rescheduling

The DEA is evaluating moving cannabis from Schedule I to Schedule III under the federal Controlled Substances Act, following a recommendation from the Department of Health and Human Services. If rescheduling occurs, it would not automatically legalize cannabis in Kansas, but it could reduce political friction around state-level reform and eliminate the IRC §280E tax burden on cannabis businesses (discussed below), making a future Kansas medical market more financially viable.

Federal vs. State Cannabis Law: Understanding the Conflict in Kansas

Cannabis Remains Schedule I Federally

Under the federal Controlled Substances Act (21 U.S.C. §812), cannabis is a Schedule I controlled substance. The federal government considers it to have no accepted medical use and a high potential for abuse. Federal employees and contractors can be terminated for cannabis use. Federally licensed firearms dealers cannot sell to known cannabis users (per ATF Form 4473). Cannabis businesses cannot access FDIC-insured banking services without risk to the financial institution.

IRC §280E and Future Kansas Cannabis Businesses

If Kansas establishes a licensed cannabis market, businesses will face a federal tax burden under Internal Revenue Code §280E. This provision disallows ordinary and necessary business expense deductions for any trade or business trafficking in Schedule I or II controlled substances. Cannabis businesses cannot deduct most operating expenses on federal returns; only cost of goods sold (COGS) remains deductible. This results in effective tax rates far above comparable retail businesses. Until federal rescheduling removes cannabis from Schedule I or II, §280E applies regardless of state law.

DEA Rescheduling Review

The DEA's ongoing review of cannabis scheduling could result in cannabis moving to Schedule III. Schedule III substances are not subject to §280E, which would dramatically change the economics of state-legal cannabis businesses. Kansas legislators and business interests should monitor DEA Federal Register notices for rulemaking updates.

Federal Tax Considerations

Cannabis businesses face unique federal tax implications due to their classification as Schedule I controlled substances under the Controlled Substances Act. As a result, they are subject to IRC § 280E, which limits the deductions available to these businesses.

• IRC § 280E prohibits cannabis businesses from deducting ordinary and necessary business expenses, allowing only the deduction of Cost of Goods Sold (COGS).
• Businesses must carefully calculate COGS to maximize allowable deductions, as all other expenses remain non-deductible under federal law.
• Forms such as IRS Form 1065 (for partnerships) and Form 1120 (for corporations) must be filed, ensuring accurate reporting of income and COGS.
• The federal banking gap remains an issue, as banks are often reluctant to work with cannabis businesses, leading many to operate on a cash-only basis.
• The SAFE Banking Act, which aims to provide access to banking services for cannabis-related businesses, has stalled in the Senate, maintaining the cash-heavy environment.
• Kansas may not conform to all federal tax provisions; consult with a state CPA to understand any state-specific implications.
