Author Description

Drug use is at least as longstanding as recorded history. Many centuries ago humans, as well as some animal species, discovered medicinal and intoxicant properties of a variety of plants. Nowadays drug users' options have been vastly expanded by new discoveries of plant materials and by new compounds developed in both legal and illegal laboratories.

If analysis of the specimen reveals the presence of a drug or drugs, that finding can become critical evidence in legal proceedings. The admissibility or weight of the evidence then frequently is argued. Was the analysis of a specimen conducted properly? Were the instruments and procedures reliable and appropriate?

Such highly technical questions are beyond common knowledge, and we are fortunate here to be instructed about these issues by the authors of Chapters 2-5. These wide-ranging examinations of the medico-legal aspects of drugs have been written by a group of uniquely knowledgeable individuals. Their willingness to
