ST. PAUL, Minn. (AP) — Officials in Iowa and Minnesota are exploring a system to allow Iowa residents to buy medical marijuana oil from their northern neighbor, lawmakers from both states have told The Associated Press.

Iowa's Legislature has struggled this year to expand a 2014 law that legalized marijuana oils for certain patients suffering seizures but left them nowhere to buy it. Iowa House Speaker Linda Upmeyer said Friday an agreement with Minnesota is one option they're now considering.

Minnesota's program launched last summer. The novel setup could bring more patients to the two companies in Minnesota that are struggling with low enrollment.

But it would also raise some federal concerns. And it could pit Iowa residents with long drives to the closest dispensary in Rochester, Minnesota — three hours northeast of Des Moines.
