Sigh...
I read the link, and it's like the old kiddie game where you start a story at one end of a line of **** and the story that makes it to the other end is NOT the same story that started.
For a long time, hundreds of years, Kief was (and is) the name of the short, specific strain of Cannibus plant grown there in Morrocco.
I had my kief blend made by a cobbler/kief vendor in the old market (Medina) in Rabat. This is a mixture of nasty hard arab tobacco ground to a powder and mixed with the crushed and cleaned Kief plant flowers, or buds. Those 3 section pipes with the little clay bowls are Kief pipes. Morroccons would sit with a mix, dip the pipe in and fill it, then play cards and ***** mint tea while smoking the Kief mix.
Mmmmmm...Morroccons are the only Arabs who smoke bud, not hashish. Hash is made there but only for export or for visiting foreigners. As a rule...
Nowadays Kief is used as a name for anything (pollen raw sold as Kief, for instance, or nasty badly made oil mixed with crumbled oregano and called...Kief) that needs an official get-high name.
But now you know the real story!
I hung around Morrocco in the 70s.
