cocaine
[U] Uncountable
This term carries a heavy social and legal stigma, evoking images of illicit trade, addiction, and high-risk behavior. It is frequently associated with luxury or excess in pop culture, yet in medical or legal contexts, it is treated as a dangerous controlled substance. While it is chemically distinct from other stimulants, in common parlance, it often serves as a shorthand for a specific type of fast-paced, high-energy lifestyle associated with the 1980s or the underground club scene.
Used as a mass noun because it refers to the chemical substance or powder regardless of the amount.
