you manage to quash the cultivation of one illegal crop (opium poppies), and the farmers just switch to another (cannabis):
Late on an October afternoon, Muhammad Ayud, 30, a kindly sharecropper, was finishing a day of work at the three-acre parcel he farms here in this poor village just outside the town of Balkh. His plot was covered by a forest of cannabis plants, some more than nine feet tall.
“This is nothing,” he said, gesturing toward the towering plants. “If you give it real fertilizer, you’d see how tall it grows!”
man, I want to be a kindly sharecropper with cannabis plants so gargantuan you have to use a cherrypicker to get at the topmost parts, or a chainsaw to cut them down.
