Large-scale evaluation of ion mobility spectrometry for the rapid detection of synthetic cannabinoid receptor agonists in infused papers in prisons.

Synthetic cannabinoid receptor agonists (SCRAs), colloquially known as "spice," are commonly used in prisons and enter establishments via the mail in the form of infused papers. Many prisons use benchtop ion mobility spectroscopy (IMS) instruments to screen mail and seized materials for the presence of SCRAs and other controlled substances. The selectivity and sensitivity of Rapiscan Itemiser 3E and Itemiser 4DN Ion Trap Mobility Spectroscopy™ (ITMS™) systems were evaluated using 21 SCRA reference standards.

Detection and quantitation of synthetic cannabinoid receptor agonists in infused papers from prisons in a constantly evolving illicit market.

Drug misuse in prisons contributes to increased disruption and violence and negatively impacts prisoner safety, rehabilitation, and recovery. Synthetic cannabinoid receptor agonists (SCRAs), colloquially known as "spice", are infused into papers and are of particular concern in a prison setting where they are commonly vaped. Methods for the qualitative and quantitative analysis of SCRA infused papers, including impurity profiling, were developed using gas chromatography-mass spectrometry (GC-MS) with qualitative confirmation by ultra high pressure liquid chromatography with photodiode array and quadrupole time of flight mass spectrometry detection (UPLC-PDA-QToF-MS) and applied to 354 individual seized paper samples originating from 168 seizures from three Scottish prisons.
