When you use a grinder it separates the weed into two parts: The ground up normal weed, and the keef (it seperates them with a fine screen). The keef is normally the very edges of the weed and other small bits of the plant which contain high amounts of thc on/in them. The normally light green powdery substance contains a much larger amount of thc per milligram than the same amount of full buds.
