Hemp is legal in Montana — under state law — but without administrative rules completed by the Montana Department of Agriculture and a federal waiver or license of some kind, actual industrial hemp cultivation is unlikely.
Montana’s hemp legislation history is as follow:
1999: HR-2 was a house resolution calling upon the federal government to allow hemp. The resolution passed with a vote of 95-4: https://en.wikipedia.org/wiki/Industrial_Hemp_Farming_Act_of_2009
2001: SB-261, an act authorizing the production of industrial hemp: http://legis.wisconsin.gov/assembly/59/kremer/media/1298/17-1117_1.pdf
It was SB-261 that was passed by both houses of the Montana Legislature and became law: https://nifa.usda.gov/industrial-hemp
Lacking administrative rules issued by the Montana Department of Agriculture and a DEA waiver or change in federal law, industrial hemp cultivation in Montana is not currently happening. However, H1009, a Federal law which would allow the industrial hemp industry to begin growing hemp again, was introduced in the US House in February 2007.
If you’re a Montana farmer interested in industrial hemp agriculture, please read our Farmers’ Letter and visit our Agricultural Education project page.
In nearby North Dakota, the state government provides an industrial hemp FAQ, Regulations, and License Application. MHC wants Montana to follow North Dakota’s lead with regards to industrial hemp for both economic and ecological reasons.
