Khat overwhelmingly rules life in eastern Ethiopia, where all roads (in fact one only) lead to Somaliland and its port of Berbera. No, not Somalia itself, but a breakaway autonomous region that has existed, unrecognised internationally, since 1991. Thundering along the road past rolling savannah and escarpment are dozens of Isuzu trucks, their open backs piled high with sacks of khat, the favoured drug of the region.
Yemen is a huge consumer, also Somaliland and Djibouti, while exports go as far as Holland, China and, until recent changes in drug classification, the UK and Australia. And sometimes road transport is not a truck but a camel… as above.
