The Montana Legislature has passed a bill that would overhaul marijuana product labeling and education requirements, with a final vote of concurrence in the House expected later today.
Montana State Capitol Building.
Once the House approves the amended version, the legislation will head to Governor Greg Gianforte for consideration.
House Bill 792, introduced by Representative Mike Cunningham (R) and co-sponsored by a bipartisan group of lawmakers, passed the Senate 46 to 3 after clearing the House in a 94 to 5 vote earlier this month. Given it was amended in the Senate, it went back to the House for a concurrence vote. Yesterday, the House approved the Senate changes through a second reading, with a third reading (scheduled for today) required before it can be sent to the governor.
If signed into law, HB 792 would mandate that all marijuana retail locations display consumer education posters featuring required warnings and the universal marijuana warning symbol. These posters must include graphic depictions and specific health warnings, such as risks of anxiety, psychosis, cannabinoid hyperemesis syndrome, and impacts on fetal development and infant cognitive function. Driving under the influence of marijuana must also be clearly denoted as a crime.
In addition to the signage, every marijuana product would need to include warning labels printed in a legible font next to a yellow triangle with an exclamation mark, identifying the product as containing marijuana. Products with over 10% THC would require an extra warning in bold red print noting their high potency.
The bill gives the Montana Department of Revenue expanded rulemaking authority to enforce these new requirements. This includes determining packaging and label standards, ensuring they are not attractive to children, and requiring resealable, child-resistant containers. It also mandates that packaging and point-of-sale displays include quick reference codes or links to addiction support resources.
If enacted, the legislation will take effect July 1, 2026, giving state agencies and marijuana businesses ample time to comply with the new regulations.
