Kansas Cannabis Advertising Laws

Kansas has no cannabis advertising framework, because it has no lawful cannabis market. Its CBD standard requires no THC for general sale rather than the federal 0.3 percent threshold. Claire and Lola's Law creates an affirmative defence to possession rather than a programme, and authorises no sales and no licences.

If you are advertising hemp-derived or CBD products here, or targeting Kansas shoppers from a neighboring legal market, our cannabis marketing agency page covers what channels are open.

Marijuana is a Schedule I controlled substance under Chapter 21, Article 57 and may not lawfully be sold in Kansas. Advertising for CBD products containing no THC is governed by the Kansas Consumer Protection Act and federal law rather than by any cannabis-specific framework.

Marijuana is a Schedule I controlled substance in Kansas under Chapter 21, Article 57 of the Kansas Statutes Annotated. There is no adult-use programme, no medical programme, and no licensing framework. Possession is a criminal offence, a Class B misdemeanour on a first conviction with escalation thereafter.

Two provisions exist and neither creates a market.

Zero-THC CBD. Kansas removed CBD from the controlled substances definition in 2018, but only where the product contains no THC. A product at or below the federal 0.3 percent threshold remains a controlled substance in Kansas if any THC is present.

Claire and Lola's Law. Enacted in 2019 by Senate Bill 28 (SB 28), this creates an affirmative defence to prosecution for possession of CBD oil containing up to 5 percent THC where the person has a debilitating medical condition and appropriate documentation. It creates no registry, no licences and no lawful in-state supply.

There is no cannabis advertising rule set, because there is no cannabis regulator and no licensed industry.

This page is part of our state-by-state cannabis advertising laws library, covering all 50 states and the District of Columbia.

There is no cannabis advertising rule

Kansas has no cannabis regulator, no licensing authority and no advertising regulations. This is an absence in state law rather than an omission from this page.

Product classification

For general sale in Kansas a CBD product must contain no THC. Kansas's standard is stricter than the federal 0.3 percent threshold, so a certificate of analysis showing compliance with the federal threshold does not establish compliance with Kansas law. The certificate must show no detectable THC.

Claire and Lola's Law

The affirmative defence applies to a qualifying patient's possession. Senate Bill 28 authorises no business to sell or distribute higher-THC CBD oil in Kansas, and establishes no supply channel within the state.

Business name and licence number

Not required. There is no cannabis licensing framework.

The required warning statements

None. Kansas mandates no warning language in advertising, because there is no cannabis advertising framework.

How the warnings have to appear

Not applicable, as none are required.

When the warnings are not required

Not applicable. There is no disclosure requirement to disapply.

Hotline number

No. Kansas requires no helpline, hotline or poison control number.

Prohibited content

No cannabis-specific content rule exists. What applies instead:

• The Kansas Consumer Protection Act, K.S.A. Chapter 50, Article 6, which prohibits deceptive and unconscionable acts in consumer transactions
• Federal restrictions on disease, treatment and cure claims
• General advertising law

Discounts, coupons, and price promotion

No cannabis-specific restriction exists. General advertising law applies.

Pre-approval

Not applicable. There is no agency with authority to approve cannabis advertising.

What the Law Requires

Kansas states no cannabis advertising age standard, because there is no framework. Kansas has not established a statewide minimum age for CBD purchases.

Audience Percentage Thresholds

Kansas sets no audience composition percentage. This is an absence in state law rather than an omission from this page. Other states do set one: Connecticut requires reliable evidence that at least 90 percent of the audience is 21 or older, and Delaware requires at least 85 percent. Kansas states no equivalent figure for any medium.

Event sponsorship

Kansas sets no audience threshold specific to event sponsorship.

Where the burden sits

Kansas imposes no audience composition evidence or recordkeeping duty for cannabis or hemp advertising. For a regional campaign, the applicable thresholds are those of the other states in the delivery footprint.

Age Gating and Consent

Websites

Kansas prescribes no website age gate and no age verification requirement for cannabis or hemp advertising.

Direct communication

Kansas states no age affirmation requirement for direct or individualized communication.

Location-based devices

Kansas has no location-based device provision.

Established customers

Not applicable. There is no cannabis advertising definition to which an exception would attach.

People Depicted in Ads

Kansas states no casting restriction, no minimum age for persons appearing in advertising, no prohibition on depicting consumption, and no cartoon, mascot or celebrity provision, because there is no cannabis advertising framework.

The Kansas Consumer Protection Act prohibits deceptive and unconscionable acts in consumer transactions, and federal law restricts disease, treatment and cure claims, including where implied by imagery.

Restricted Locations and Buffer Distances

Kansas states no cannabis advertising buffer. There is no distance requirement around any facility type, no transit prohibition and no public property prohibition, because there is no cannabis advertising framework. This is an absence in state law rather than an omission from this page.

General outdoor advertising law and municipal sign ordinances apply to physical placement.

The State Line

Kansas borders Missouri and Colorado, which operate adult-use programmes, Oklahoma, which operates a medical programme, and Nebraska, which is building one. Marijuana may not lawfully be sold or possessed in Kansas. The Kansas City metropolitan area spans the Kansas and Missouri state line within a single designated market area.

Can You Run a Digital Out of Home Screen in Kansas?

Kansas states no cannabis-specific out of home prohibition. A screen advertising a compliant zero-THC CBD product is subject to general outdoor advertising law and the local sign ordinance. Marijuana may not lawfully be sold in Kansas.

Compliant Use of Geotargeting

• Kansas states no cannabis advertising buffer, so there is no facility exclusion layer required by state law.
• Build explicit Kansas exclusions into Missouri, Colorado and Oklahoma campaigns for THC products, and test them against the Kansas City DMA specifically, since that market spans the state line.
• Classify products against the Kansas zero-THC standard rather than the federal 0.3 percent threshold.
• Claire and Lola's Law is an affirmative defence to possession and creates no lawful in-state supply, so it supports no marketing route.
• For regional campaigns, the applicable audience and content standards are those of the other states in the delivery footprint.

Neither programme exists, so there is no advertising rule set for either.

Recreational. Marijuana is a Schedule I controlled substance. Possession is a Class B misdemeanour on a first conviction, escalating to a Class A misdemeanour on a second and a felony on a third. Kansas has not decriminalised at state level, though some municipalities have reduced local penalties.

Medical. Kansas has no medical cannabis programme. Claire and Lola's Law, enacted in 2019 by Senate Bill 28, creates an affirmative defence to prosecution for possession of CBD oil containing up to 5 percent THC where the person has a debilitating medical condition and appropriate documentation. It is named for two children with severe epilepsy. Because it is a defence rather than an authorisation, it creates no registry, no licences and no lawful in-state supply.

Medical programme legislation has been introduced repeatedly and has passed the House in at least one session without being enacted.

Who regulates hemp here

The Kansas Department of Agriculture administers the commercial industrial hemp programme for cultivation and processing.

Non-intoxicating hemp and CBD

Kansas removed CBD from its controlled substances definition only where the product contains no THC. A full-spectrum product compliant with the federal 0.3 percent threshold contains THC and is a controlled substance in Kansas. Broad-spectrum and isolate products with no detectable THC are lawful for general sale.

Intoxicating hemp-derived cannabinoids

Delta-8, THCA, HHC and similar cannabinoids contain THC and sit outside the zero-THC allowance. The federal definition of hemp narrows in November 2026; the Kansas standard is set by state law and is unaffected by that change.

What it means for advertising

Kansas imposes no cannabis advertising framework, so the state law question is whether the product may lawfully be sold rather than how it may be advertised. A product lawful under the federal threshold may be a controlled substance in Kansas. Classify each product against the zero-THC standard and hold a certificate of analysis showing no detectable THC before building a media plan that delivers into Kansas.
