90% dip in Afghan opium production

Afghanistan produces more than 80% of the world’s opium and heroin. Most finds a way into western markets via Iran and Turkey, or through the porous border with Pakistan. Satelite data shows a 90% dip in opium cultivation in Helmand after a Taliban imposed ban last year. All is not what it appears. Opium is a sturdy crop that can be stockpiled without risk.

In the impoverished hinterlands of Afghanistan, opium was, until recently, a currency that could fetch anything. Prices have crashed due to overproduction. During the Taliban's 2000 ban, demand rose and so did prices. Just like any other market manipulator, the Taliban dipped into its stockpiles to meet demand.
