Afghanistan: Helmand's drug abuse problem

It is more than six months since British troops left Helmand province in southern Afghanistan.

The Taliban now control much of the north of the province, and Helmand continues to be one of the main areas for the illegal production of poppies.

The United Nations forecasts another record harvest of opium poppies in Afghanistan - the raw material for heroin - with Helmand again providing most of the crop.

As David Loyn reports, the social impact on Helmand is disastrous.
