In this Monday, April 23, 2018, photo, Lukas Inman, 19, interacts with his father in Colorado Springs, Colo. Inman suffers from a rare and severe form of epilepsy called Lennox-Gastaut Syndrome. A British pharmaceutical company is getting closer to a decision on whether the U.S government will approve the first prescription drug derived from the marijuana plant, but parents, including Lukas,' who for years have used cannabis to treat severe forms of epilepsy in their children are feeling more cautious than celebratory.
