Its cheap and nasty resin. Usually has lumps of plastic embedded into it, when you smoke it it smells a bit like sausages, it has a harsh almost petrolly taste. It does give you a very "heavy" high which makes you lethargic. All in all only to be used in an emergency, its also known as "rocky" up north.

This reminds me, how come this is the only hash I've ever come across in 10yrs of smoking?
