A Cleveland breathalyser company is preparing to trial a world-first all-in-one alcohol and drug testing device.

Alcolizer has partnered with Britain's Oxtox to develop the technology, which has detachable clips to provide both alcohol breath testing and drug testing, The Bayside Bulletin reports.

Current roadside drug testing must be performed by specially trained officers and takes between three and five minutes.

The Alcolizer ADU (Alcohol and Drug Unit) takes a saliva sample and returns a reading within 30 seconds.
