Challenge
A client approached us after a long-term driving licence ban, hoping to have their licence reinstated. The ban had been imposed years earlier due to substance use, but they had since taken significant steps towards recovery. As part of the process, they underwent a urine drug test through the DVLA, which unexpectedly returned a positive result for opiates. This outcome meant their licence remained revoked, despite their progress.
Solution
Confident that the urine test did not reflect their current circumstances, they sought legal support to challenge the decision. Their solicitor contacted us to arrange a hair strand drug test, which would provide a clearer picture of their drug use over the previous months.
Unlike urine tests, which only detect recent drug use within a short window, hair analysis offers a longer-term view. This makes it particularly useful in cases like this, where demonstrating a sustained drug-free period is crucial. DVLA guidelines require proof of ‘controlled use’ of drugs and alcohol before reinstating a licence. A segmented hair test, which breaks hair into sections to analyse drug use over specific time frames, was the ideal approach.
Our laboratory conducted the test, focusing on the months leading up to the client’s request for reinstatement. The results showed no traces of opiates, supporting their claim of abstinence. Once confirmed, we provided a detailed, court-admissible expert report explaining the findings. All documentation, including the report and certificates of analysis, was delivered within three days of receiving the samples.
Result
Following further review by the DVLA, alongside the results we provided, the client’s driving licence was reinstated.
This case highlights the importance of accurate, science-backed drug testing in legal challenges and demonstrates how hair analysis can meet the DVLA’s requirements for assessing long-term drug use.
