Myanmar has declared a war on opium. In a remote valley in Shan State, police armed with weed-whackers move through fields of poppies. They leave behind them a carpet of stems. These fields are the livelihood for many of the residents in the villages. Local farmers are distraught at the sight of their destroyed fields. Myanmar has appealed to foreign donors for half a billion dollars to finance a program to wean the thousands of households off poppy-growing.
