Nuristanica broad leaf drug origin?

@roms I think these recent genomics papers would be of interest, they analyzed fossil pollens and seed/achene samples found in archaeological sites with some good data inferences about cultivated vs wild using crop pollens etc. Very interesting and pointing to Yunnan as the source of the hops/cannabis divergence but perhaps this area of Nuristan and its neighbors as the source of cannabis sativa:
