Myanmar has declared a war on opium. In a remote valley in Shan State, police armed with weed-whackers move through fields of poppies, leaving behind them a carpet of stems. However, local farmers whose livelihood depends on the weed are distraught at the government's action. 　　Moe Mohm, a 48-year-old widow with six daughters are one of them."I thought nothing. I just wanted to cry. I can't do anything about this (poppy field eradication). There's no food to eat. The money I borrowed I have already spent on fertilizers. I have no more money to pay back, no more money for food." 　　Myanmar has appealed to foreign donors for half a billion dollars to finance a program to help the thousands of households off poppy-growing. But it's not an easy task. United Nations Office on Drugs and Crime said new crops can't be planted until the rain season starts in June or July. 　　United Nations Office on Drugs and Crime in Myanmar Country Manager, Jason Eligh: "We've got a very narrow window. We've got a period now of about six months until they can plant again. If aid is not arriving, if they don't get the assistance they need in that period, then there is a very real chance that they'll go back to poppy." 　　The UN estimates about 256,000 households are involved in opium poppy cultivation. Myanmar produced an estimated 610 tonnes of opium last year, making it the world's second biggest opium supplier after Afghanistan.
