David McDonald Barriers and Facilitators to Translating Research on Drug Driving Thresholds into the Australian context

Basic Priority Rating Model The size of the problem, usually based on incidence or prevalence rates; The seriousness of the problem, usually based on its urgency, severity, economic loss and impact on others; The effectiveness of interventions available to address the problem; and Other environmental factors including propriety, economics, acceptability, legality of solutions and availability of resources.

Drug Driving Thresholds Are non-zero per se drug driving laws that set drug quantity thresholds for the drug driving offence justifiable (based on the science) and practicable in the ACT context? To what extent does it matter to the ACT that the states and the NT have a zero- tolerance per se legislation approach to drug driving? Would non-zero per se thresholds remove the disparity in penalties between drink driving and drug driving? What psychoactive substances would be included in a non-zero tolerance risk threshold based system? Are testing levels high enough to provide meaningful data and to have a sufficiently strong deterrent effect as to improve road safety at the population level?
