BOISE, Idaho (AP) — Up to 25 Idaho children with persistent seizures will soon have access to an experimental drug derived from marijuana, but experts say far more children could benefit from the treatment.

An April executive order from Gov. Butch Otter is allowing the very limited use of the non-psychoactive drug. Otter signed the order after vetoing less-restrictive legislation that would have allowed the marijuana extract to be used in children with severe seizure disorders.

The Spokesman-Review reports that Idaho's strict stand against any legal use of marijuana puts it alone among all of its neighbors. Utah and Wyoming recently allowed legalized the supervised use of cannabidiol, or CBD oil, to treat intractable epilepsy or seizure disorders.
