Is smack heroine or oxy?

Question by Alex: Is smack heroine or oxy?
Or something else? Can it refer to both? Is it oxycodone that you’d shoot up, or what is usually used intravenously other than heroin?

Not planning on using it at all, just curious. Friend of mine had an addiction and trying to figure out what it was to.
