In pictures: Growing khat

Traders at Murugene market say sales are still nothing special. One trader who used to sell 20kg a day says he now only sells half because exports to Somalia have not yet returned to normal.

And the women who sell banana tree leaves, that are used to wrap the khat, have not been earning much either.

The leaves often dry up after staying for too long at the market.

"When business was good I used to earn about $20 a day, but now I hardly get $10," says Jennifer Kabithi.
