Question to the Home Office:

To ask the Secretary of State for the Home Department, whether her Department has made an estimate of the annual profit made organised crime from the illegal drugs market in the UK.

The 2013 Home Office report, the Cost of Drugs, estimates that Organised Crime Groups generated £3.7bn in revenue from the illegal drugs market in the UK.

However, it is not possible to provide accurate figures on the profit made from the UK illegal drugs market. This is due to an absence of official statistics held in relation to its actual value and the differing "operating costs" of criminal networks. In addition, variable factors such as exchange rates and drug purities, influenced by a range of supply and demand factors, regularly affect retail and wholesale costs.
