OMAHA, Neb. (AP) — The next Omaha Science Cafe will focus on the use of a marijuana plant extract to treat epilepsy.

Cannabidiol is extracted from the Cannabis sativa plant and is different from the extract that provides the high from smoking marijuana.

Dr. Deepak Madhavan is involved in the oversight of a clinical study investigating the use of cannabidiol in patients with drug-resistant epilepsy. At Tuesday’s Science Cafe he’ll discuss the substance and its potential clinical use.

The event is scheduled to begin at 7 p.m. at the Slowdown, 729 N. 14th St.
