DETECTION OF MISREPORTED DRUG-USE IN FORENSIC POPULATIONS - AN OVERVIEW OF HAIR ANALYSIS

Criminal and civil forensic evaluations are frequently complicated by misreported (denied or exaggerated) substance abuse. This article prov ides an introduction to the use of radioimmunoassay of hair (RIAH). RI AH with gas chromatography/mass spectrometry confirmation is superior to the more commonly employed urinalysis in its (1) wider window of de tection, (2) ability to provide a chronology of substance abuse, and ( 3) resistance to countermeasures. The potential implications of the RI AH procedure to retrospective and prospective forensic evaluations are discussed.
