What did the "Frozen Addicts" call the drug?

[Ranchoth]

...I'm sure a few of you have heard of the "Frozen Addicts" from a few years ago, drug users who took a "synthetic heroin" containing the chemical MPTP, and were left in a catatonic, Parkinsonian state by neurological damage.

But my question is...what did the addicts themselves call the drug? It did have a name besides "synthetic heroin," right?

Apparently, the related MPPP was called "super Demerol", but this was manufactured incorrectly, and became the neurotoxin MPTP, from where the "Frozen Addicts", including the manufacturer, came from.
