Trends in reports of driving following illicit drug consumption among regular drug users in Australia, 2007-2013: Has random roadside drug testing had a deterrent effect?

Although there is some evidence that drug-driving among key risk groups of regular drug users is declining in Australia, possibly reflecting a general deterrent effect of RDT, experiencing RDT appears to have no specific deterrent effect on drug-driving. Further intervention, with a particular focus on changing attitudes towards drug-driving, may be needed to further reduce this practice among these groups.
