title: Drugs WorkBook (DWB): a tool for the analysis of illicit drugs in seized materials.
abstract: Accurate and reliable analytical measurements are essential when data are to be used to assist the Court in deciding whether or not a drug offence has been committed and therefore about either the innocence or guilt of the accused. The Italian law on drugs demands that compliance with specification limits be assessed on the basis of the actual content of controlled substance contained in seized materials. As a consequence, the role of measurement uncertainty, significant figures and rounding errors becomes critical. In order to assist analysts of forensic toxicology laboratories with illicit drug-related cases, a software tool named Drugs WorkBook (DWB) has been developed. The tool is useful for the quantification of illicit drugs in seized materials along with their measurement uncertainties, the assessment of compliance to specification limits, the printing of comprehensive laboratory reports and the organization of case archives. Other quality control topics, such as control charts, are included. The tool's databases can be edited by the user and maintained up to date. The tool is made freely available to the scientific community.
