The world's drug landscape is a grim, high-stakes game of Whac-a-Mole, where as we try to flatten the opium fields of Afghanistan, we're getting knocked sideways by a flood of high-potency cannabis, lab-made fentanyl, and enough cocaine to suggest the global supply chain is far more efficient at delivering misery than actual goods.
