Here's something that may surprise many Western Australians. Not that long ago, drivers who had recently used cocaine could not be detected through roadside drug testing in WA. While police could detect other common illegal drugs, cocaine was not included in roadside screening.
However, that has now changed. WA Police have introduced new laws and roadside drug screening devices capable of detecting cocaine.
How cocaine testing has changed roadside drug screening in WA
For many years, roadside drug testing in Western Australia focused on detecting THC, methylamphetamine and MDMA. While these substances could be identified during roadside screening, cocaine was notably absent from the testing regime.
The recent rollout of new multi-drug testing devices has changed that. WA Police can now detect cocaine during roadside drug testing, giving officers another tool to identify drivers who may be affected by illicit substances and strengthening enforcement efforts across the State.
According to the WA Government, the expanded testing program is intended to improve road safety by broadening the range of drugs that can be identified through roadside screening. The addition of cocaine detection represents one of the most significant updates to WA's roadside testing program in recent years and reflects ongoing efforts to address drug-impaired driving.
See the WA Police cocaine roadside testing announcement for further details.
WA joins other Australian jurisdictions
The introduction of cocaine roadside drug testing in WA represents another step towards a more consistent approach to roadside drug enforcement across Australia. Most other Australian jurisdictions now include cocaine in roadside drug testing programs.
Victoria is the most notable exception. In Victoria, THC, methylamphetamine and MDMA are detected in roadside drug screening, but cocaine isn’t. The exclusion is a frequent point of public debate, with the reasons often cited as historical precedent, data priorities, and even the cost of testing.
A stronger approach to drug-impaired driving
The introduction of cocaine roadside drug testing in WA represents another step towards a more comprehensive approach to roadside drug enforcement.
Road safety authorities have long identified drug-impaired driving as a major contributor to road trauma. By expanding screening capabilities, police can now identify a broader range of drivers who may be affected by illicit substances and pose a risk to themselves and others on the road.
The change also reinforces an important message: if you choose to use illicit drugs, getting behind the wheel is never worth the risk.
What the change means for drivers
For people who use cocaine, the change in roadside drug testing is a significant wake-up call.
While cocaine was previously not included in WA's roadside screening program, drivers who choose to drive after using the drug are now at a much greater risk of being detected.
For other road users, the change is likely to be welcomed. Road safety authorities continue to highlight the risks associated with drug-impaired driving, which can affect judgement, concentration and reaction times. Expanding roadside screening to include cocaine gives police another tool to identify potentially impaired drivers and improve safety on WA roads.

What does this mean for workplaces?
While the announcement is primarily focused on road safety, it also has important implications for workplaces across Western Australia.
The biggest impact is likely to be felt by businesses where employees regularly drive on public roads as part of their role. This includes industries such as transport, logistics, field services, construction, mining support services, utilities, healthcare and community services.
Employees who drive for work should be aware that cocaine can now be detected during roadside drug testing in WA. This creates an additional compliance and safety consideration for organisations that manage vehicle fleets or rely on workers travelling between sites.
For many workplaces, however, the change may have little impact on their existing drug testing programs.
Unlike WA's previous roadside testing regime, cocaine has long been included in most workplace drug testing across Australia. Many organisations already screen for cocaine alongside cannabis, amphetamines, methamphetamines, MDMA and opioids as part of broader fitness-for-work programs.
In fact, all workplace drug testing conducted by Integrity Sampling includes the ability to detect cocaine. As a result, many employers already have measures in place to identify the drug in workplace settings, regardless of recent changes to roadside testing laws.
The announcement does, however, serve as a useful reminder for employers to review their drug and alcohol policies, employee education programs and testing procedures regularly to ensure they continue to support a safe workplace.
