I know of a feral cannabis population in Moravia, Check Republic, not all that far from Slovenia. The Moravian plants are descendents of Scythian drug cultivars planted by the Romans many centuries ago,
Hemp was cultivated in central Europe during prehistoric times, way before the Romans reached there !
I have some doubts about the supposed Turkish origin of southern Europe strains. First because hemp was used in Europe long before Turkish invasion. Second, in most gardens located in countries which have been under Turkish rule, it is not hemp which you find growing, but POPPIES ! This plant originates from Turkey and as matter of fact, Turkish armies spread it all around ! but for hemp ? hmmm, really not sure...
Irie !
