Statistics are provisional and subject to revision. Preliminary drug tests are used as identifiers for further evidentiary testing (secondary tests and then ChemCentre WA analysis tests) which forms the evidentiary basis of preferring a charge for driving with a prescribed illicit drug. Not all positive preliminary tests will result in positive results for secondary tests or ChemCentre WA analysis.
