It appears that the original Chamba story is (at least geographically) that it is a region wide term used to describe herb grown throughout the Malawi / Tanzania region of south central Africa.
Most references tie it to Malawi gold which appears to be a sativa strain which is a primary parent for most of the hybrids created for export since the early to mid 90's. It's akin to saying mexican is the parent of most of the herb grown in Mexico, not very specific as to genetics. Most reference to Chamba are as the herb pressed and wrapped in banana leaves grown and processed in the hill country in Tanzania north of the large lake that seperates the two countries (this fits with the tale I was told back in 81).
There is some documentation of various tribes growing and using Cannibis back to 1870 or so. All my research thus far is pretty random. I mention this as a reference to biological isolation of strain causing adaptive evolution very different from our "America's" Sativa varietal.
In any event look for Chamba @ "The Emerald Cup"... Educate, Smoke, Vote
