A suicide pill was a pill containing a lethal substance that an individual could ingest deliberately in order to quickly commit suicide. Rebel Alliance Intelligence Service operatives carried such pills, nicknamed "lullabies." One such suicide pill was the affide crystal, a neurotoxin which looked like a crystal, which was hidden within some spies as a false tooth and used in the event of capture or torture.
