                         Quick Review
                       ● Forensic toxicologists detect and identify drugs and poisons in body fluids,
                         tissues, and organs in matters that pertain to violations of criminal laws.
                       ● Ethyl alcohol is the most heavily abused drug in Western countries.



                    Toxicology of Alcohol


                    The subject of the analysis of alcohol immediately confronts us with the primary
                    objective of forensic toxicology—detecting and isolating drugs in the body to
                    determine their influence on human behavior. Knowing how the body metabo-
                    lizes alcohol provides the key to understanding its effects on human behavior.
                    In the case of alcohol, however, the problem is further complicated by practical
                    considerations. The predominant role of the automobile in our society has man-
                    dated the imposition of laws to protect the public from the drinking driver. This
                    has meant that toxicologists have had to devise rapid and specific procedures for
                    measuring the degree of alcohol intoxication. The methods used must be suitably
                    designed to test hundreds of thousands of motorists annually without causing
                    them undue physical harm or unreasonable inconvenience, while at the same
                    time providing a reliable diagnosis that can be supported and defended within the
                    framework of the legal system.
