Number Three

A street name for Heroin free-base (often looks like a light-brown powder), the often abused illegal narcotic. It can be smoked.

The number comes from the steps of purification until turning heroin into a salt (Number Four, that is).
Mostly used in Europe.

I mixed my Number Three with citric acid in order to turn it into a water-soluble salt for injecting.
