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...
Ok if you could separate the black hash from the Afghanistan area from the soap bar because none of the two are the same. Color of hash does not mean quality, you have to smoke that stuff to determine that.
Soap bar is a hideous concoction that probably has about as much real hash as it has many other things loaded into it. Stories about soap bar being sold in the UK are just insane. I brought it up because to someone who may know what hash is but still a rookie for sight and smell black hash and soap bar may look similar at a glance.
Now I just had time to write something down quickly but hash changes color because of how it is mixed, different shades in the trichomes and the plant material as well. Some are blonde, some are tan and some reach that deep brown color. It's so relative that the Afghanistan and Morroco areas Kif Mountains and such have such a wide range of colors there.
My point being here is that that hash is harder to find now than it used to be. It's not making its way over here as much as it used to. Lots of crack downs. The borders were not flexible back then but rather didn't really put two and two together until later. Hash was around really good for 70's, mostly made its way from Canada via Middle East then trickled down to US.
Spare me the Mexican hash...that isn't exactly on the radar...
