The Taliban's Opium War (New Yorker)
Doug Wankel walked up to an angry-looking farmer who was watching his field being destroyed and asked him, through an interpreter named Nazeem, how much he got for his opium. Twenty-one thousand Pakistani rupees for a four-kilo package, the farmer said, and he harvested three to four kilos per jirib (a local land measurement equivalent to about half an acre). He added, “I get only a thousand rupees per jirib of wheat, so I’m obliged to grow poppies.” That comes to about thirty-three dollars from an acre of wheat, and between five hundred and seven hundred dollars from an acre of poppies.
