chiva
n.— «Known by hundreds of nicknames—chiva, skag, horse, smack and junk, to name a few—heroin is available all over Santa Cruz County, but it’s almost never “China white”—the white powder seen on television.» —“Chiva the Destroyer” by Michael Mechanic MetroActive (Santa Cruz, California) Feb. 22, 1996. (source: Double-Tongued Dictionary)
The term now appears on government glossaries of street drug terms.

Thanks! I usually rather get drug terms out of running text (such as news or feature articles) because the government lists are highly unreliable–they put any old term on the list. Many of the them simply cannot be substantiated.
Chiva, by the way, comes from Spanish and also means she-goat.
