The Food and Drug Administration is giving the University of Alabama at Birmingham the green light to study the use of a marijuana derivative to treat seizures.    Parents of children with seizure disorders persuaded the Alabama Legislature last year to pass a bill authorizing UAB's Department of Neurology to do a study of the marijuana derivative cannabidiol as a seizure treatment.    A UAB spokesman said Tuesday that the FDA has approved the study, but has requested modifications. A university review board will discuss the changes next month.
