Minnesota’s adult-use market is barely a year old, and its advertising law is one of the tightest in the country. A window poster can count as an illegal outdoor ad here.
Minnesota cannabis advertising laws ban most outdoor advertising, require a state warning on every ad, and restrict location-based targeting. This guide is for dispensary owners, operators, marketing managers, and cannabis or hemp brand marketers planning Minnesota campaigns. It explains the rules, who enforces them, and how to grow reach without risking your license.
This page is general information, not legal advice. Rules change often, so confirm with your compliance officer and licensed cannabis counsel before launching a campaign. For channel strategy, see our Minnesota cannabis marketing hub.
Yes. The Legislature legalized adult-use cannabis in 2023, creating Minnesota Statutes chapter 342. State-licensed adult-use retail sales began September 16, 2025, according to an Office of Cannabis Management announcement. Tribal nations opened sales on tribal lands earlier.
Minnesota also has a long-running medical cannabis program, now administered within the Office of Cannabis Management. OCM says that starting January 1, 2027, the adult-use and medical supply chains will be streamlined, with the distinction moving to the point of sale.
Federal status also changed. The DEA moved marijuana held under a state medical license to Schedule III, effective April 28, 2026. Adult-use marijuana remains Schedule I while a broader federal proceeding continues. None of this loosens Minnesota’s advertising law.
These are the rules that shape most Minnesota cannabis marketing regulations in practice:
The Office of Cannabis Management (OCM) licenses and regulates cannabis businesses, hemp businesses, and the medical program. The advertising law is Minnesota Statutes section 342.64, enacted in 2023 and amended in 2024. OCM’s permanent rules in chapter 9810 took effect April 14, 2025, but most advertising requirements come straight from the statute.
OCM explains how it reads the statute in Guidance Memo 2025-07, its cannabis and hemp advertising guidance. The memo quotes the statutory definition of an advertisement. It means “any written or oral statement, illustration, or depiction that is intended to promote sales” in any medium. That reaches print, radio, TV, online ads, and social media.
Under 342.64, subdivision 1, ads may not contain false or misleading statements or unverified health claims. They may not promote overconsumption or depict anyone under 21 using the products. Images or characters likely to appeal to people under 21 are prohibited. Ads also cannot show alcohol or people drinking it.
Every ad must include the warning OCM requires. For cannabis businesses and products, the warning opens with an age statement. The first line reads “Warning: Cannabis products are not for use by anyone under the age of 21”. The text continues with statements on drowsiness and impairment, lack of FDA approval, and pregnancy risks. Hemp businesses use a parallel warning for hemp products containing THC.
Copy the full warning from OCM’s current guidance into every template. A missing warning is one of the easiest violations to avoid.
Minnesota dispensary marketing restrictions are strongest offline.
Outdoor ads for cannabis and hemp products are prohibited. OCM’s guidance names hanging banners, tent or feather flags, sandwich boards, neon signs, and outward-facing window wraps or posters. Any window or door sign visible from outside counts as outdoor advertising.
The exception is narrow. A cannabis or hemp business may erect up to two fixed outdoor signs on its building or property. Those signs must still follow the content rules.
Ads may not run in print, radio, television, or other media where 30% or more of the audience is reasonably expected to be under 21. The statute calls for reliable, current audience data. Keep composition reports for every buy.
Big venues need extra care. Signage or sponsorships at U.S. Bank Stadium reach mixed-age crowds and may raise both outdoor and audience questions. Get counsel review before any venue deal.
OCM licenses cannabis event organizers, and chapter 9810 includes a part on events. The first event organizer license was issued in September 2025. Brands should confirm event-specific marketing limits with the organizer and OCM before committing budget.

Digital is where most growth happens, and the statute speaks to it directly.
Minnesota regulates hemp-derived products alongside cannabis, and 342.64 covers both. Businesses that sell lower-potency hemp edibles may advertise other goods or services outdoors. Those outdoor ads cannot relate to or mention the hemp edibles.
The federal picture is shifting too. A November 2025 federal appropriations law narrowed the definition of hemp, and its effective date has been the subject of further congressional action. Hemp brands should plan for tighter federal limits in late 2026.
OCM says failing to include required warnings can lead to enforcement action against the license holder. That action can go up to penalties or license suspension or revocation. Anyone can file an advertising complaint through OCM’s enforcement complaint form.
Medical practitioners face their own rule. A practitioner who violates the advertising limits in subdivision 7 may be barred from certifying patients for the registry.
Most early violations in new markets come from habits, not bad intent. These are the ones to catch before launch:
A simple pre-flight checklist solves most of these. Confirm the warning, the audience data, and the placement type before anything goes live.
Local governments cannot ban licensed cannabis businesses, but Minnesota Statutes 342.13 lets them set reasonable time, place, and manner limits. They may bar cannabis businesses within 1,000 feet of a school. They may also bar them within 500 feet of a day care, residential treatment facility, or park attraction used by minors. Check local sign codes too.
Dense neighborhoods mean many storefront windows. Remember that outward-facing window signs count as outdoor ads. Minneapolis dispensary SEO carries much of the load.
Local search and listings matter for neighborhood shoppers. St. Paul dispensary SEO with strong menu pages drives visits.
Visitors make up a large share of traffic. Cannabis advertising in Rochester, MN should use age-verified digital audiences, not broad placements.
Duluth hosted the first state-licensed sales of tribally grown flower in September 2025. Duluth dispensary SEO should also consider Wisconsin visitors, where cannabis remains illegal.
The Mall of America draws families and teens. Geofencing near it only works with audiences verified as 21 and older.
A compliance-first plan keeps the license safe and still moves the needle on foot traffic. Here is the playbook:

Yes, with strict limits. Licensed cannabis businesses can advertise if every ad carries the OCM warning and avoids prohibited content. Outdoor ads are banned except for two fixed signs on the property. Ads cannot run where 30% or more of the audience is under 21, and pop-up ads are prohibited.
Yes. Adults 21 and older can buy cannabis from state-licensed retailers, which began sales on September 16, 2025. Tribal nations opened sales earlier on tribal lands. The medical program continues under the Office of Cannabis Management, which regulates both markets.
No. Minnesota bans outdoor advertising for cannabis and hemp products, and OCM names billboards as prohibited. The only exception for cannabis businesses is up to two fixed outdoor signs on the business’s own building or property. Window signs visible from outside also count as outdoor ads.
Only with verified adult audiences. The statute prohibits ads directed at location-based devices unless the device owner is 21 or older. Use providers that can verify age, and keep documentation. Avoid geofences around family destinations, schools, and youth venues even with verified audiences.
Every cannabis ad needs OCM’s warning. Its first line reads “Warning: Cannabis products are not for use by anyone under the age of 21”. The full text also covers impairment, lack of FDA approval, and pregnancy risks. Hemp ads use a parallel warning. Copy the current text from OCM guidance.
The same advertising statute covers medical cannabis businesses. Practitioners who certify patients have extra limits. They cannot use slang like “pot” or “weed,” imply OCM endorsement, or show cannabis flower or smoking paraphernalia. Violations can bar a practitioner from certifying patients.
Minnesota cannabis advertising laws leave little room for improvisation. Warnings on every ad, no outdoor promotion beyond two signs, and age-verified digital targeting are the baseline. Operators who build those systems now will own local search while the market matures.
