Question 3

What is the age limit for hemp products in Montana?

Accepted Answer

Question 4

Will hemp products be legal in Montana after November 2026?

Accepted Answer

Montana already prohibits converted hemp cannabinoids under HB 948 (2023) and caps compliant products at 0.5 mg per serving under HB 49 (2025) — limits stricter than the federal standard. Section 781 of H.R. 5371 (Continuing Appropriations and Extensions Act, 2026, Pub. L. 119-37), effective November 12, 2026, sets a 0.4 mg total-THC-per-container cap nationally, so its impact on Montana is low because the state is already more restrictive.
