Illinois cannabis advertising rules, explained: what Section 55-20 bans and where ads can't go

This article is general information, not legal advice. Laws change and facts differ; for your situation, talk to a lawyer licensed in Illinois.

Illinois limits cannabis advertising in one short section of the Cannabis Regulation and Tax Act, 410 ILCS 705/55-20. The source note on ILGA's page lists only 2019 acts (P.A. 101-27 and 101-593), so we found no amendment since. The section applies to cannabis business establishments and also to "any other person or entity." It has four parts.

Part (a): what no cannabis ad may contain

No advertising may include any statement or illustration that:

1. is false or misleading;
2. promotes overconsumption of cannabis or cannabis products;
3. shows someone actually consuming cannabis;
4. shows a person under 21 consuming cannabis;
5. makes any health, medicinal or therapeutic claim about cannabis or cannabis-infused products;
6. includes an image of a cannabis leaf or bud; or
7. includes any image designed or likely to appeal to minors, including cartoons, toys, animals or children, or any other likeness to images, characters or phrases designed to appeal to, or encourage consumption by, people under 21.

Part (b): where cannabis ads can't go

No one may place or keep a cannabis ad, in any form or medium:

• within 1,000 feet of the perimeter of school grounds, a playground, a recreation center or facility, a child care center, a public park, a public library, or a game arcade that admits people under 21;
• on or in a public transit vehicle or transit shelter; or
• on or in publicly owned or publicly operated property.

Part (b)(4) also bars an ad that contains false or misleading information, promotes excessive consumption, depicts a person under 21 consuming cannabis, includes the image of a cannabis leaf, or includes images designed or likely to appeal to minors, including likenesses popularly used to advertise to children, "any imitation of candy packaging or labeling," or that "promotes consumption of cannabis."

Part (c): the educational exception

The first two parts "do not apply to an educational message." Section 55-20 doesn't define that term itself, and how far the exception reaches is a question for regulators and courts. We don't try to answer it here.

Part (d): promotions

Cannabis businesses and any other person or entity may not encourage sales of cannabis or cannabis products by giving them away, by conducting games or competitions related to consuming them, or by providing promotional materials or activities of a manner or type that would appeal to children.

The same idea in the new hemp rules

The ban on health claims has a parallel in hemp. The Illinois Department of Revenue's bulletin FY 2027-04 on the state's new hemp law says hemp products may not carry any health claim on their labels. That bulletin also says products above 0.4 mg of total THC per container become cannabis in Illinois starting November 12, 2026. This section covers cannabis advertising only; the hemp label rule is a separate law.

How we apply it

The Highline Report follows section 55-20 in its own pages: no health claims, no leaf or bud imagery and nothing aimed at readers under 21. Our editorial policy explains how.
