Lilian Greenwood, the UK’s minister for the future of roads, has expressed interest in exploring new technologies to accelerate the prosecution process for drug driving offences.

Speaking in response to a parliamentary question from Andrew Snowden MP, Ms Greenwood highlighted the potential of a saliva-based testing system already used in countries like Australia and France.

Reviewing the evidence

The system involves collecting evidential saliva samples at the roadside from drivers who fail an initial DrugWipe test.

These samples are then processed in laboratories within days, enabling prosecutions to be completed in weeks rather than months.

D.tec International, the supplier of DrugWipe kits to UK police forces, has welcomed the minister’s interest.

It describes the current system, which relies on blood samples for laboratory confirmation, as “slow and ineffective.”

According to D.tec, delays in the existing process mean that drug drivers often remain on the roads for up to six months before facing prosecution.

During this time, some offenders re-offend multiple times, posing significant risks to public safety.

Repeating results

Recent data reveals the extent of repeat offences:

  • 33,020 drivers were convicted of drug driving more than once in the 11 years up to July 2024.
  • 3,431 individuals were prosecuted four or more times.
  • 54 drivers were caught and convicted at least ten times.

 

Industry and Political Support for Change

Ean Lewin, managing director of D.tec International, emphasised the urgent need for reform:

“We remain committed to sharing our three decades of expertise in combating drug driving and working collaboratively with policymakers to implement this proven solution,” Lewin said.

He praised Andrew Snowden MP for his dedication to road safety and his efforts to raise the issue in parliament.

“The need for reform has never been clearer,” Lewin added.

“By taking decisive action, we can create safer roads, save lives, and ensure justice is delivered swiftly and effectively. We stand ready to play our part in making this vision a reality.”

Next Steps

As interest in faster, saliva-based testing grows, the government may consider piloting or adopting the technology in the UK.

Advocates argue that implementing such measures could reduce delays in prosecuting offenders and deter repeat drug driving, contributing to safer roads nationwide.

Ms Greenwood has pledged to continue discussing and reviewing the potential benefits of this system as part of broader efforts to more effectively tackle drug driving.
