The Montana Legislature has approved House Bill 636, a sweeping measure that imposes new regulations on marijuana products. The Senate passed the bill today in a 37 to 12 vote, following House approval last month by a vote of 84 to 15.
The legislation, sponsored by State Representative Josh Etchart and backed by a group of Republican lawmakers, would restrict the THC content in marijuana products, including placing a 35% THC limit on cannabis flower.
The measure would reduce the maximum THC content in a single serving of an edible from 10 milligrams to 5 milligrams, while maintaining an 800-milligram limit per package for most product types.
Additionally, the bill outlines strict packaging rules, mandating that marijuana products be sold in child-resistant, resealable containers with plain white labels that only include the seller’s name, product name, THC or CBD content, health warnings, and ingredients. The use of images or branding designed to appeal to minors is explicitly banned.
The bill also reinforces prohibitions on sales to minors, disallows dispensaries from offering synthetic cannabinoids or alcohol, and introduces tighter oversight on product labeling and packaging approvals by the state’s Department of Revenue.
With the bill now cleared by both chambers, it heads to Governor Greg Gianforte for consideration. If signed into law, or allowed to become law without a signature, the new regulations would take effect on July 1, 2026. If the governor vetoes the measure, the measure has enough support to override it if they choose to do so (a veto override requires a two-thirds majority).
