Illinois recently became the 20th state to legalize medical marijuana. And, some in Iowa are pushing for a similar initiative. Today on River to River, host Ben Kieffer sits down with Iowa patients and families who believe cannabis to be an effective medicine for their suffering. He talks with medical professionals about the benefits and the concerns of using the drug as medicine. And, State Senator Joe Bolkcom and Iowa’s drug policy coordinator Steve Lukan give a preview of how this issue will play out in the upcoming Iowa legislative session.
