    Article Snippet: Correspondence María del Mar Ramírez Fernández, Federal Public Service Justice, National Institute of Criminalistics and Criminology, Brussels, Belgium.. Email: mariadelmar.ramirezfernandez@just. fgov.be Abstract Interpretation results of hair analysis, particularly for cocaine, can be challenging due to the need to differentiate between active use or passive contamination.. Our study aimed to assess the impact of varying degrees of passive cocaine exposure hair analysis results and their interpretation.
