The illicit use of these materials is a worldwide problem, and for many years, part of the benzodiazepines have been abused as rape drugs. For example, flunitrazepam (Rohypnol) is most commonly linked by media reports to drug\u2010facilitated sexual assaults, more commonly referred to as \u201cdate rape.\u201d Furthermore, there are growing concerns for other misuses of these drugs. Over the last few years, there was an increase in the number, type, and availability of new psychoactive substances (NPS) belonging to the benzodiazepine group, challenging standard forensic labs to fully identify the chemical structure of new, unknown benzodiazepines.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This work demonstrates a new application of the automated tool for the detection and identification of benzodiazepine analogues using high\u2010resolution\u2010accurate\u2010mass LC\u2010MS analysis, followed by \u201cCompound Discoverer\u201d (CD) software data processing, to automatically detect various benzodiazepine analogues by picking peaks and compare them to in silico calculated modifications made on a predefined basic backbone. Subsequently, a complete structural elucidation for the proposed molecular formula is obtained by MS\/MS data analysis of the suspected component.<\/jats:p>\n                  <\/jats:sec>\n
