There were almost 2,500 casualties in relation to drug-driving in 2021, representing a 260% increase since 2012, analysis of data from the Department for Transport (DfT) suggests.

The issue has also been felt in the courts, says IAM RoadSmart, with the number of drug-driving convictions increasing year-on-year, reaching 12,500 in 2019.

Almost half (44%) of these crimes are perpetrated by repeat offenders, with many of these cases occurring within one year.

IAM RoadSmart’s analysis comes amid worrying reports that, due to testing protocols which requires blood samples to be taken by a healthcare practitioner, some police officers are resorting to bringing drug-driving suspects to A&E departments to take a sample.

A IAM RoadSmart survey of 2,028 motorists found that one-in-10 respondents said that they have driven, or been a passenger in a vehicle, where the driver has been under the influence of illegal drugs.

The survey also discovered that 6% of people would be comfortable driving while under the influence of illegal drugs, and 14% of those surveyed stated that they would not stop a family member or friend who was planning to drive while under the influence of drugs.

IAM RoadSmart’s most recent annual safety culture report showed that motorists consider drink and drug-drivers as one of the biggest risks to their personal safety – more than other issues such as speeding on residential streets, people driving aggressively or not wearing a seat belt.

Neil Greig, director of policy and research at IAM RoadSmart, said: “With cases surging and attitudes as they are, Britain’s drug-drive picture is a bleak one.

“IAM RoadSmart has already proposed a smart package of solutions to help address this issue, including: developing a dedicated drug-drive course, prescription reform and for the Government to finally release the outcome of its own drug-driving consultation.

“If these are actioned, we might finally see progress made on this critical road safety issue before more lives are tragically lost.”

IAM RoadSmart recently called on the Government to reform the approach to drug-driving.
