Guidance Memo | GM-2025-07

Background
Minnesota law requires that all advertisements for cannabis and lower-potency hemp edible (LPHE) products contain a warning developed by the Office of Cannabis Management (OCM). In consultation with industry and public health professionals, OCM has developed required warnings that accompany any published advertisement for a cannabis business, a hemp business or any cannabis product or lower potency-hemp edible product (including hemp beverages).  
Required warnings
Minnesota Statutes, section 342.64, subdivision 1(7), states that "Cannabis businesses, hemp businesses, and other persons shall not publish or cause to be published an advertisement for a cannabis business, a hemp business, cannabis flower, a cannabis product, a lower-potency hemp edible, or a hemp-derived consumer product in a manner that does not contain a warning as specified by the office regarding impairment and health risks.”

This means that any advertisement (whether in print, radio, television, online, or through social media) for either a cannabis or hemp business, cannabis flower, a cannabis product, a lower-potency hemp edible, or a hemp-derived consumer product must contain the following warning language:

Cannabis businesses, cannabis flower and cannabinoid products

Warning: Cannabis products are not for use by anyone under the age of 21. Cannabis use may cause drowsiness, affect focus, reaction time, and decision-making. These products are not evaluated or approved by the FDA. Pregnant people should avoid cannabis due to the risk of low birth weight, premature birth, stillbirth, and harm to fetal brain development.

Hemp businesses, lower-potency hemp edibles, and hemp-derived consumer products

Warning: Hemp products containing THC are not for use by anyone under the age of 21. Using hemp products containing THC may cause drowsiness, affect focus, reaction time, and decision-making. These products are not evaluated or approved by the FDA. Pregnant people should avoid hemp products containing THC due to the risk of low birth weight, premature birth, stillbirth, and harm to fetal brain development.

An advertisement is defined in Minnesota Statutes, section 342.01, subdivision 5, as “any written or oral statement, illustration, or depiction that is intended to promote sales of cannabis flower, cannabis products, lower-potency hemp edibles, hemp-derived consumer products, or sales at a specific cannabis business or hemp business and includes any newspaper, radio, Internet and electronic media, or television promotion; the distribution of fliers and circulars; and the display of window and interior signs in a cannabis business.” Importantly, an advertisement does not include a fixed outdoor sign on the exterior of a cannabis or hemp business’s building that meets the requirements in Minnesota Statutes, section 342.64, subdivision 2(b).

Failure to include the required warnings may result in enforcement action against the license holder or business, up to and including penalties or license suspension/revocation. Complaints about business or license holder activities, including advertisements, may be submitted to the OCM through the Enforcement Complaint Reporting form.
