Heaped in plastic bags in a small room in rural southern Afghanistan, the white crystals glisten. They are "export quality" methamphetamine, and will be trafficked to countries as far away as Australia. Once there, the 100kg (220lb) stored in this room will have a street value of around £2m ($2.6m). Outside, smoke billows from two barrels where new batches of meth are being cooked.
Drugs are big business in Afghanistan, and under the Taliban, trade is booming. The country has long been linked with heroin, but in recent years, it has also emerged as a significant producer of crystal meth - another dangerously addictive drug.
