DES MOINES, Iowa (AP) – Medical marijuana supporters are hopeful the Iowa Legislature could expand the state’s limited cannabis oil law. The Des Moines Register  reports that Republican Rep. Clel Baudler plans to propose a bill that would allow the production and distribution of medical cannabis oil in Iowa.

The Legislature passed a law in 2014 that allows Iowa residents to possess cannabis oil for the treatment of epilepsy. That law is set to expire in July. A separate law currently makes it illegal to manufacture or distribute that oil in the state, while federal law prohibits its transportation across state lines.

Threase Harms, who lobbies on behalf of the Epilepsy Foundation and the upper Midwest chapter of the National Multiple Sclerosis Society, says the organizations will continue to try and educate lawmakers about the issue to build broader support.
