"The Afghan president acknowledged this morning that it would take ten to 15 years to eradicate poppy-growing in Afghanistan, not the one year that he had originally hoped."

"Afghan poppies supply 87 per cent of the world's heroin and make up more than half of the country's GDP. More than 2 million people, 8.7 per cent of the population, work in the country's poppy fields."

""Three years ago I thought we were going to destroy poppies this year and that’s it," Mr Karzai said. "But no, it is a real economy, there are people depending on it. It will take time to develop alternatives.""

...if ever.
