Still not online here in Nairobi, but listening to the BBC World Service on the radio, I was struck by two (sort of linked) stories. One said that marijuana is now the biggest cash crop in the USA. The other was about coca in Bolivia and how the new president of that country, Evo Morales, is suggesting that cultivation of the crop should be expanded and new products developed based on the traditional uses of the plant. Then in the Daily Nation this morning there is an article about how miraa (or qat, Catha edulis) farming is taking a hit in northern Kenya after miraa flights to Somalia were banned by the new authorities there. Now livelihoods are threatened and there is apparently an upsurge in crime in miraa growing areas. Anybody out there want to draw some conclusions?
