MACY, Neb. (AP) — Leaders of the Omaha Tribe in Nebraska are considering land in western Iowa for growing marijuana. The Sioux City Journal reports tribal members approved three referendums Tuesday giving the Tribal Council the authority to legalize marijuana for medicinal and recreational use and to grow plants for industrial hemp. The tribe is based in northeast Nebraska, but its reservation extends into Iowa’s Monona County.

Tribal Chairman Vernon Miller says a study will examine whether the business would make financial sense. Miller says leaders will watch the performance of the Flandreau Santee Sioux’s marijuana resort on its South Dakota reservation. Miller says it’s unclear whether the Omaha Tribe’s casino, Blackbird Bend, could become a similar resort. Miller says the tribe will ensure its efforts wouldn’t violate federal or state laws.
