DES MOINES, Iowa (AP) — A renewed effort to legalize the use of marijuana to treat chronic epilepsy has won the support of a legislative panel. A three-member subcommittee unanimously approved a measure Wednesday that would allow the use of oil derived from marijuana medically as a last-resort treatment for chronic epilepsy. It now goes to the Ways and Means Committee.

The form of marijuana that would be legalized cannot be smoked and doesn’t create a high, and it would have to be obtained in another state that produces the oil.

Efforts by women who have children with epilepsy changed some lawmakers’ views on the issue and sparked a revival of a bill previously believed to be dead. New policy measures cannot be brought up late in the session unless legislative leaders sponsor them.
