UK drivers face mobile drug-testing device

The first mobile drug-testing device has been approved by the British government for use on drivers suspected of being under the influence.

The device, known as Drugwipe, is the first portable device that can detect the presence of cannabis and cocaine — two of the most common substances used by drug-drivers — by analysing a small quantity of saliva.

Results are indicated by the appearance of lines on the device— similar to a pregnancy test —within eight minutes.
