Barbiturate Street Names: A Historical Slang Lexicon

Barbiturate slang flourished in the mid-20th century but is now largely historical, as these drugs have been replaced by benzodiazepines and Z-drugs for sedation and hypnosis. The colorful terminology often reflected capsule color or effect.

Modern Context

Barbiturates are now Schedule II–IV controlled substances with narrow therapeutic indices. Current depressant slang has shifted: "benzos," "bars" (alprazolam), "xans," "downers." Understanding historical slang aids interpretation of older medical records, forensic toxicology, and cultural references.
