  author={Magdalena Taschwer and Manfred G Hofer and Martin G. Schmid},
The illicit drug market of psychoactive substances for human abuse is continuously expanding and developing. Besides already known substance classes like cathinones, amphetamines or synthetic cannabinoids, further derivatives such as benzofurys, thiophenes, and structural analogues of methylphenidate entered the global market recently. As many of these new compounds contain a stereogenic centre it is supposed that their isomers may differ in their pharmacological effects as it is the case with… 

Determination of the chiral status of different novel psychoactive substance classes by capillary electrophoresis and β‐cyclodextrin derivatives
