Growing in popularity more than any other illegal drug, methamphetamine has been shown to produce a paranoid psychotic state, which may recur months or years after use. The first to cover virtually every aspect of amphetamine/methamphetamine use and abuse, this book reviews the history, pharmacology, pathology, and physiology of methamphetamine as well as its use in criminal forensic cases. It addresses Daubert considerations as well as victim/witness credibility, competency to confess and to stand trial, criminal responsibility, extreme emotion as mitigation to murder, and dangerousness. It also details statutes and case law to represent perspectives of both the prosecution and the defense.
