Minnesota Cannabis Advertising Laws

If you’re running a cannabis business in Minnesota, advertising is the constraint that defines what’s possible. The rules are codified in § 342.64 of the Minnesota Statutes, with packaging and labeling specifics in § 342.62, § 342.63, and Rule 9810.1400. They’re enforced by the Office of Cannabis Management (OCM), and they apply to every license type — dispensaries, cultivators, manufacturers, wholesalers, lower-potency hemp edible retailers, medical cannabis combination businesses, and any ancillary business advertising cannabis products to Minnesota consumers.

This guide breaks down exactly what you can and can’t do, separates state law from platform policy, and names the channels that actually work for a compliant Minnesota cannabis marketing agency client in 2026. Whether you’re applying for a license, building a brand pre-launch, or already operating, this is the rulebook in plain language with every citation you’ll need to verify.

The big picture: who, when, and who enforces it

Minnesota legalized adult-use cannabis in August 2023 when Governor Tim Walz signed HF 100 into law. The statute was codified into Chapter 342 of Minnesota Statutes. Non-tribal adult-use retail sales launched in September 2025, after OCM completed its initial licensing process and the administrative rules in Chapter 9810 took effect.

The advertising restrictions live in § 342.64. The formal definition of “appeal to individuals under 21” — which controls a huge amount of what design and copy is permitted — is in § 342.62, Subd. 1a. The label specifications (universal THC symbol, 21+ Poison Control symbol, required statements) live in Rule 9810.1400.

Enforcement is by the Office of Cannabis Management (OCM). OCM has authority to revoke or suspend licenses, impose administrative penalties, and require compliant materials before further advertising or operation.

The rules apply to every business holding a cannabis or lower-potency hemp edible license — cannabis retailers, cultivators, manufacturers, wholesalers, microbusinesses, mezzobusinesses, lower-potency hemp edible retailers and manufacturers, and medical cannabis combination businesses. Ancillary businesses (legal, real estate, packaging vendors) aren’t directly bound, but if you advertise on behalf of a licensed business, you’re effectively bound through them.

What you can’t do under § 342.64

Outdoor advertising is banned — with one narrow exception.§ 342.64, Subd. 2 All outdoor cannabis advertising is prohibited, except for up to two fixed signs on the exterior of the business itself.

Media where 30%+ of the audience is under 21 — banned.§ 342.64, Subd. 3 You can’t run cannabis ads in any medium where 30% or more of the audience is reasonably expected to be under 21, based on reliable, current audience composition data.

Unsolicited pop-up advertisements — banned.§ 342.64, Subd. 4 Pop-up ads on the internet are explicitly prohibited.

Minor-appealing imagery — banned.§ 342.62, Subd. 1a + § 342.64, Subd. 1 No toys, robots, cartoons, animals, characters commonly used to advertise to children, or imitations of candy, cereal, sweet, or chip brand names. Fruits and vegetables are prohibited unless they accurately describe an ingredient in the product.

False or unverified health claims — banned.§ 342.64, Subd. 1 Advertisements cannot make false, misleading, or unverified health or therapeutic claims.

Overconsumption or alcohol imagery — banned.§ 342.64, Subd. 1 No depictions promoting overconsumption, no people under 21 consuming cannabis, no alcohol or alcohol consumption imagery.

What you can do (with conditions)

Organic search and SEO — fully permitted. § 342.64 doesn’t regulate organic search. SEO, content marketing, Google Business Profile management, and AI search visibility are the highest-leverage channels for Minnesota cannabis businesses right now, and the foundation Trip starts every engagement with.

Direct, individualized communication — permitted with age affirmation.§ 342.64, Subd. 5 Email, SMS, and other direct channels are allowed if the recipient is age-affirmed as 21+ before you send. The statute says the affirmation method “may include user confirmation, birth date disclosure, or another similar registration method.” In practice: every signup form must capture and verify a date of birth.

Location-based device targeting — permitted to 21+ device owners.§ 342.64, Subd. 6 Cellular and other location-based device ads are allowed only when the device owner is 21+. Critical for any geofenced or location-based digital campaign.

Up to two fixed exterior signs — permitted.§ 342.64, Subd. 2(b) On the building or property of the cannabis business itself.

Audience-verified paid media — permitted under conditions.§ 342.64, Subd. 3 Print, radio, TV, podcasts, and digital channels are permitted if under-21 audience composition stays below 30%, verified by audience data — not just self-declared targeting.

Required OCM warning on every ad.§ 342.64, Subd. 1(7) Every advertisement must include the warning specified by OCM regarding impairment and health risks. Verify the current exact warning text with OCM before publishing — it can be updated independently of the statute.

Platform reality: state law ≠ platform policy

This is the single most-misunderstood point in Minnesota cannabis advertising.

The working paid channels for Minnesota cannabis businesses in 2026:

• Cannabis-friendly ad networks (Fyllo, Surfside, Kanna, Mantis)
• Programmatic display on age-gated inventory
• Influencer partnerships with 21+ Minnesota-based creators
• 21+ event sponsorships and on-premise activations
• Direct, age-affirmed email and SMS to verified 21+ lists

By channel

SEO and organic search

Not restricted by § 342.64. The dispensaries and brands that build local SEO foundations in Minneapolis, St. Paul, Duluth, Rochester, and across the state today will own organic visibility in 2027 and 2028. AI search visibility (ChatGPT, Perplexity, Google AI Overviews) is increasingly meaningful for category and product queries — build for it now.

Email and SMS

Permitted under § 342.64, Subd. 5 with age affirmation. Every signup must capture and verify a date of birth before any cannabis marketing message goes out. Build that into every form, every lead magnet, every newsletter signup — not just the “official” ones.

Social media (organic)

Compliant organic presence is permitted on Instagram, LinkedIn, X, and TikTok, subject to (a) the 30% under-21 audience threshold and (b) each platform’s own content guidelines. Don’t rely on it for direct sales; do rely on it for brand authority, community, and a credibility signal to wholesale buyers and licensing reviewers.

Paid digital

Programmatic display on cannabis-friendly networks (Fyllo, Surfside, Kanna, Mantis) is the working alternative when standard ad platforms reject your placements. These networks serve age-gated, cannabis-compliant inventory at scale and respect § 342.64’s audience composition rules by default.

Influencer

Partnerships with 21+ Minnesota-based cannabis creators are permitted. All creators must be over 21. Disclose properly under FTC guidelines and each platform’s branded-content rules — Instagram’s paid partnership label, TikTok’s branded content toggle.

OOH (Out-of-Home)

Effectively prohibited. Only exception: up to two fixed exterior signs on the cannabis business itself per § 342.64, Subd. 2. No billboards, no transit ads, no mall posters, no stadium signage.

Events

21+ event sponsorships and on-premise activations are permitted, subject to general § 342.64 advertising rules and any host venue or local restrictions. Trade shows, industry conferences, and 21+ consumer events are all in play.

Required warnings and disclosures

On product labels — Rule 9810.1400, Subp. 3 requires three things on every package sold to a Minnesota consumer:

• Universal THC symbol — the IICPS (International Intoxicating Cannabinoid Product Symbol) with “THC” beneath.Subp. 3(A) Minimum 0.5″ × 0.5″, printed legibly and conspicuously.
• 21+ warning symbol with Poison ControlSubp. 3(B) Minimum 0.75″ tall × 0.6″ wide. Yellow background, black text, white-on-red “21+ NOT FOR CHILDREN” octagon, with Poison Control “800-222-1222”.
• Required label statementSubp. 3(C) — verbatim: “Keep this product out of reach of children. This product may be unlawful outside the state of Minnesota.” Minimum 6 pt font.

On advertisements — § 342.64, Subd. 1(7) requires every ad to include “a warning as specified by the office regarding impairment and health risks.” OCM specifies the current exact text separately and can update it without statutory amendment. Verify with OCM before publishing.

Penalties and enforcement

OCM enforces § 342.64 and the associated rules. The office has authority to:

• Impose administrative penalties for violations
• Require immediate correction or pull-down of non-compliant advertising
• Suspend or revoke licenses for repeated or willful violations
• Refer matters for criminal prosecution where statutory violations rise to that level

Specific penalty amounts and procedures are set by OCM and are subject to change. Verify the current penalty schedule with OCM directly at mn.gov/ocm before relying on any specific dollar figure. The practical reality: most enforcement comes through routine inspections and customer or competitor complaints, and OCM gives a chance to correct most non-egregious violations before escalating.

What to do next

If you’re building or operating a Minnesota cannabis business, here’s the practical punch list:

1. Confirm the current OCM-specified advertising warning text before publishing any new creative.
2. Audit your existing signup forms — every cannabis marketing email or SMS recipient must be age-affirmed as 21+ before send.
3. Confirm your packaging and labels meet Rule 9810.1400 — universal THC symbol, 21+ Poison Control symbol, required label statement.
4. Don’t budget for paid social media as a primary channel — those platforms don’t accept cannabis ads regardless of state legality.
5. Invest in SEO, age-affirmed email and SMS, programmatic display on cannabis-friendly networks, and 21+ influencer partnerships.

FAQ

Can a Minnesota cannabis business run Facebook ads targeted to 21+ users in Minnesota?

Minnesota law would permit it under § 342.64, Subd. 3 and Subd. 6 with proper audience verification and age-targeting. Facebook won’t accept the ad regardless — platform policy prohibits cannabis advertising, full stop. Same goes for Google, TikTok, X, and Snap. The working paid alternatives are cannabis-friendly ad networks, programmatic display on age-gated inventory, and influencer partnerships.

What’s the under-21 audience threshold I have to stay below?

30%, under § 342.64, Subd. 3. Audience composition must be verified by reliable current data — not just self-declared targeting. This applies to print, radio, TV, podcasts, and any other medium where audience composition is measurable.

Is email marketing permitted for a Minnesota dispensary?

Yes, under § 342.64, Subd. 5, if every recipient is age-affirmed as 21+ before sending. The statute specifies the affirmation method “may include user confirmation, birth date disclosure, or another similar registration method.” Practically: capture and verify a date of birth on every signup form, and don’t send a single cannabis marketing message to a contact who hasn’t completed it.

Can I run a billboard for my dispensary in Minneapolis?

No. Outdoor advertising is prohibited under § 342.64, Subd. 2, except up to two fixed signs on the cannabis business’s own building or property. Billboards, transit ads, mall posters, and any off-premise outdoor placement are out.

Do I need to include a warning on every ad?

Yes. Under § 342.64, Subd. 1(7), every advertisement must include the OCM-specified warning regarding impairment and health risks. The exact wording is set by OCM and can be updated without statutory amendment — verify with the regulator before publishing.
