Production: The Hash is produced by hand like in Afghanistan and Nepal. From what I heard the Hash production is organized by Europeans.
Color: Black on the outside, greenish-brown inside.
Smell: Reminds somewhat of Weed.
Taste: Reminds somewhat of Weed.
Consistency: Hard to very hard (when older).
Effect: Not as physical and stony as the other black kinds.
Potency: Medium to potent.
Availability: Very rare. When available usually in the form of sticks, unfortunately often quite old.
Various: Pieces of stems and seeds can sometimes be found in the dope. This was tried by ZZ in Amsterdam, and was the most disappointing of the gear we got. High quality varieties are probably available though - watch out for the really old stuff.
