This series edited by forensic scientists, provides an overview of current knowledge in forensic sciences, by reviewing the progress in this rapidly growing field. Each volume provides an insight into the various aspects of this science. It is the belief of the editors, that every forensic worker should be informed about all branches of his science, even if he may very well be specialised in one or few of them. This research text on forensic science, toxicology, criminalistics is intended for scientists and practitioners in the above-mentioned fields, consultants and expert witnesses.

Methamphetamine is one of the most widely abused stimulants and together with amphetamine has led to serious social problems. Numerous papers in the fields of medicine, toxicology, pharmacology, sociology, etc. have appeared. In Japan for example about 20,000 to 22,000 persons have been arrested in recent years on suspicion of abuse, smuggling or illegal manufacture of drugs. In other countries, stimulant drugs also present social problems and efforts have been directed toward prevention. Although marked development of analytical techniques in the field of forensic sciences has been achieved, there is a need for a continuous review of recent advances. A review of studies on methamphetamine has therefore been made from the standpoint of forensic toxicology and legal medicine. Attention has been directed to biological samples because analyses and interpretation for the purpose of t.oxicological and As a detailed survey on abuse drugs involving clinical practice are important. 1 methamphetamine and amphetamine has been made by Fishbein and covered the time before 1980, we refer only to data and events appearing after 1980.
