A brand name for an analgesic combination drug containing hydrocodone and paracetamol, often used for recreational purposes.
"Despite being prescribed as a legitimate painkiller, some people misuse vicodin to get high because it contains hydrocodone and paracetamol."
The brand name Vicodin combines "Vi," possibly derived from the Roman numeral for six to reflect its potency relative to codeine, with "codein" and the suffix "-in." This construction highlights that the drug's active ingredient is hydrocodone, which is roughly six times as strong as codeine.
