Compounds classified as Designer Drugs have been synthesized for several decades. This is not a precise scientific term and should only be applied to those drugs that are synthesized from common chemicals and skillfully marketed under attractive, often exotic names. Because of many designer drugs are novel or designed to evade detection, they can be overlooked or difficult to detect or characterize. The last decade has seen a proliferation of such substances, such that keeping abreast of this huge number of new drugs is a difficult task for forensic chemists and toxicologists. Compiled by a team originating from the Regional Departments of Criminal Investigation in Kiel, Hamburg, and Wiesbaden, Germany, Mass Spectra of Designer Drugs has been developed to help forensics and toxicology labs combat this epidemic. Mass Spectra of Designer Drugs 2013 covers the entire range of designer drugs up to December 2012. Approximately 70% of the compounds covered in the Designer Drugs do not appear in either NIST 2011 or the Wiley Registry of Mass Spectral Data, 9th Edition.

Steroids are of considerable therapeutic importance and play a substantial role in endocrinology, a medicine branch dealing with disorder of the endocrine system, an integrated system of small organs that involve the release of extracellular signaling molecules known as hormones. On the other hand, steroids are increasingly being abused for performance enhancement by professional athletes, Olympians and even amateurs. The identification of small amounts of steroids in body fluids is an analytical challenge. GC/MS is one of the key analytical techniques applied in these areas. For the fast and reliable identification of steroids, mass spectral reference data are essential.

The print edition contains a comprehensive listing of all compounds in order of molecular mass, showing a reference mass spectrum as well as structural formula, exact masse, GC retention times and numerous other experimental data that are relevant to the analytical toxicologist. To aid in compound identification, all substances are classified according to their toxicological categories.
