ONE in five Griffith drivers tested positive for illicit drugs according to frightening new figures from last weekend's Highway Patrol crackdown.
The operation conducted across the region found 22 of 102 tested produced positive results for cannabis or amphetamines.
Between 1pm Friday and 11pm Saturday, Highway Patrol Officers also conducted 184 random breath tests.
The tests resulted in eight traffic charges issued, including five for drink driving offences, two for driving while suspended and one for driving with a cancelled licence.
Police also issued 21 infringement notices and two defect notices for vehicles.
