To ask the Secretary of State for the Environment, Transport and the Regions if his planned roadside drug driving tests detect the presence of (a) Prozac and (b) Benyllin. [30957]

Neither of the devices which are being trialled will detect the presence of Prozac or Benyllin. The purpose of the trials is to assess the robustness and practicability of the devices when used at the roadside—not to test drivers for the presence of drugs.
