What??
The bkack putty hash from afghanistan that i know is world famous. It used to top the list in amsterdam coffee shops along with the morrocan hash, of which both were #1 sifts or close. Now its all about the bubble hash in amsterdam, but you can still get both and it is just as potent.
Both the afghan putty and the morrocan was/is sold by the tonne and shipped all over the world and techniques they use to make it have now changed much in hundreds of years... Therefore it would be stored for months at a time and yet still be moist/pliable...
I dont know where you get your info from...but it is incorrect. Or maybe incomplete...
North america never used to get that #1 sift until the 80s, when the mujahadeen traded it (and heroin) to the CIA for stinger missles to fight the russians with when at war with afghaniststan... which are facts well known around the world...
The soap bar hash that you refer to is something that i heard of but never had the displeasure to smoke... dunno where that came from...dunno why anyone would buy it...
