"This hard cover book presents an assessment of the state of the art in hair testing procedures and issues. …the book content is divided between analytical and interpretive issues and presents an excellent review in both these areas. Copious references are included with each chapter. Many of the authors of this book are well known in the field of forensic toxicology and represent an almost even split between European and American contributors. I would highly recommend this book to anyone interested in the field of hair analysis in particular, or the detection of drugs of abuse in general…"- Brian Perrigo, CR.
