Hypo

Hypo was a truth syrum used for extracting information from willed individuals, typically in interrogation situations. The Imperial Empire was known to utilize this drug; Darth Vader, during an interrogation session with Princess Leia Organa on the First Death Star, was accompanied by an interrogation droid who administered the syrum in order to break the Princess' resistance and gain the location of the hidden Rebel base.
