New series 1/3. From blighted estates to the professional middle-classes, from child crack-dealers to Ibiza's drugs tourism, these frank and shocking films reveal the scale and cost of Britain's biggest illegal industry. Tonight drug dealers describe in detail the tricks of their trade; their profits, the risks and the reasons why they deal. The film unlocks the secretive world of dealers and explodes the myths of drug taking in London, while the common assumption that drug consumption is primarily the endeavour of a wasted and damaged fringe is shattered.
Continues tomorrow at 9pm.
