In this study, handheld Raman spectroscopy and the use of two Available online 4 February 2017 excitation wavelengths, 785 and 1064 nm, were evaluated for the identiﬁcation of 60 NPS products. The products contained a range of NPS from classes including the aminoindanes, arylalkylamines, Keywords: benzodiazepines, and piperidines & pyrrolidines. Identiﬁcation was initially assessed using the New psychoactive substances
