Madhouse Cannabis Farms

As of 2026, hemp-derived THCA products are legal in Montana under the federal 2018 Farm Bill framework adopted into state law via HB 701 (2021). Products containing 0.3% Delta-9 THC or less by dry weight are not classified as marijuana, and most retailers ship freely to consumers within the state. Standard retail rules apply: COA verification, 21+ age gating at most reputable brands, and clear labeling. Total-THC point-of-sale testing is generally not required, though brands marketing in Montana typically pass total-THC voluntarily. Local municipalities may add zoning restrictions, but no statewide retail ban exists. Always confirm shipping eligibility with the brand at checkout — laws are evolving and a federal Farm Bill rewrite remains pending.
