New designer drugs, access to databases, and the changing availability of samples for analysis have changed the face of modern forensic toxicology in recent years. From use of pharmaceutical drugs in a clinical setting, through smart and counterfeit drugs, this book documents the wide range in which drugs today are abused. Diverse case examples from industry experts enable readers to understand how drugs impact on each other and how the interpretative outcomes of a case are dependent on many aspects. It is an essential resource for postgraduate students in forensic toxicology, and for researchers in forensic toxicology laboratories who need the latest data and knowledge.
