LOUISVILLE, Ky. (WDRB) -- Earlier this year, the General Assembly passed a bill allowing the limited medical use of cannabis oil.

Doctors at U of L and UK can use the marijuana extract to begin treating patients suffering from epileptic seizures -- but there's a problem. The federal government still considers CBD oil to be a controlled substance, and researchers have not been able get supplies of the oil to begin clinical trials.

"I think that the legislators and the patients' families thought that, okay, once this bill is signed by the governor, then we're going to be able to have this available," said Dr. Karen Skjei. "But you can't just go to the pharmacy and give them your doctor's prescription for CBD and have them fill it. It's a lot more complicated than a lot of people thought about."

Coming up at 4, we'll tell you how Kentucky's fledgling hemp industry could help solve the problem -- and we'll hear from a Louisville woman who has started a grassroots campaign to legalize cannabis oil.
