Isaac

Colloquial terminology in New Zealander used as pseudonym for N-methyl-1-phenylpropan-2-amine otherwise known as "crystal meth".

The term "Isaac" is thought to translate from a Kiwi phrase "Ice Crack Pee" wherein "Pee" is intended to mean "pure" and the words "Ice" as well as "Crack" both are commonly used in describing the physical appearance of this illicit substance.

It is not uncommon for an English language first name to be used in substitution for a word describing an illicit drug. In the UK, cocaine powder is frequently called "Charlie" and in America "Molly" refers to the rave drug MDMA.

"Isaac" the "Ice Crack" is occasionally heard of in Australian drug culture community, Queensland's Gold Coast region in particular. It is also used in United Kingdom (however only vary rarely).
