There have been numerous calls for increased transparency and disclosure in forensic science. However, there is a paucity of guidance on how to achieve this transparency in reports, and the impacts it may have on criminal justice proceedings. We desc

Two-dimensional gas chromatography is a mature, yet underutilised, separation technique able to provide the high resolution and peak capacity required for the study of complex samples such as oils. This paper presents the development of a comprehensi

Solid-state 13C and 19F NMR spectroscopy offers a non-destructive, highly selective protocol for the identification of forensically relevant synthetic cannabinoids on herbal substrates. Using this technique, well resolved 13C spectra were obtained th

Measures to control the expanding use of synthetic cannabinoids demand new analytical methodology to identify and determine compounds within this rapidly evolving class. Herein, we identify seven synthetic cannabinoids (AM-2201, UR-144, XLR-11, A796,

Australian clandestine drug laboratories are constantly utilising alternative methods to produce methamphetamine, in part as restrictions are placed by Government on, for example, chemicals such as phenyl-2-propanone (P2P) (in the early 1980s), or on
