It seems the message is finally getting through. In parts of Helmand Afghan farmers are this year sowing wheat instead of poppy - not because they have suddenly been converted to the argument that producing heroin is not in the national interest.
Market forces have been the deciding factor - with wheat prices doubling in the past year, and the street price of heroin falling, it is now more cost effective to grow wheat.
At last there are signs of progress being made amidst Afghanistan’s battle-scarred landscape.
