Benzo
A benzo was a type of medication used for treating anxiety, panic disorders, seizures, and insomnia. It could be administered for delayed release.
In 2399, benzos were among a number of substances administered by Raffi Musiker to Cristóbal Rios so the Beta Annari Mr. Vup would not smell it when he lied. (PIC: "Stardust City Rag")
