What Does the Law Say About Hair Strand Testing?

Paul Hunter, Founder of FTS, and Sarah Branson, Barrister at Coram Chambers, discuss the role of hair strand testing as expert opinion evidence in legal cases. They highlight that while the science behind hair testing is sound, the interpretation of drug findings requires expert analysis and must not be treated as definitive proof.

The discussion emphasises the importance of considering hair strand test results within the broader evidential context, rather than in isolation. This video also explores legal cases where expert opinions varied and stresses the need for a comprehensive approach, including assessing external factors like contamination or hair treatments. Additionally, it questions the standardised approach imposed on experts and calls for a more flexible, context-driven interpretation.
