Synthetic cannabinoids (SC) are extremely prevalent within the prison system and cause problems for prisoners, law enforcement and health services. SC are often soaked into paper then posted into prisons therefore one of the aims of this research is to collaborate with Rapiscan Systems Ltd. and local prisons in England to measure the effectiveness of trace detection methods for the indication of SC in prison post using the Itemiser 3E®. To ensure compounds did not go undetected, samples with Ion Trap Mobility Spectrometry™ peaks indicative of synthetic cannabinoids on the Itemiser 3E® were analysed using Gas Chromatography-Mass Spectrometry, Liquid Chromatography-Quadrupole Time-of-Flight Mass Spectrometry and Nuclear Magnetic Resonance Spectroscopy to identify chemical characteristics which allowed comparison to reference spectra. Sample data spanning three years from one prison's Itemiser 3E® were collated to identify trends in drug prevalence and the influence of library updates. To date, the method has identified four compounds: 5F-MDMB-PICA, MMB-4en-PICA, 4F-MDMB-BUTINACA and MDMB-4en-PINACA on prison post which were not already included on, or needed confirmatory analysis to update, the Itemiser 3E® library. As a result, the libraries on prison Itemiser 3E®s have been updated to ensure future detection of such compounds. Trends and influences from the processed Itemiser 3E® data were also reported back to the West Midlands Prison Group. This research directly benefitted both the West Midlands Prison Group and Rapiscan Systems Ltd. and it is anticipated that the continuation of this research could be expanded to a national scale.
合成大麻素(SC)在监狱系统中极为普遍,给囚犯、执法部门和卫生服务带来问题。SC 通常被浸泡在纸张中,然后邮寄到监狱,因此这项研究的目的之一是与 Rapiscan Systems Ltd. 和英格兰当地监狱合作,使用 Itemiser 3E® 测量痕量检测方法在监狱邮件中检测 SC 的有效性。为了确保不会遗漏化合物,使用离子阱迁移谱仪(Ion Trap Mobility Spectrometry™)在 Itemiser 3E® 上对具有指示性的合成大麻素峰的样品进行分析®,使用气相色谱-质谱联用仪、液相色谱-四极杆飞行时间质谱和核磁共振光谱法,以确定允许与参考光谱进行比较的化学特征。从一所监狱的 Itemiser 3E® 收集了三年的样本数据,以确定毒品流行趋势和库更新的影响。迄今为止,该方法已在监狱邮件中鉴定出四种化合物:5F-MDMB-PICA、MMB-4en-PICA、4F-MDMB-BUTINACA 和 MDMB-4en-PINACA,这些化合物尚未包含在 Itemiser 3E® 库中,或者需要确证分析来更新该库。因此,监狱的 Itemiser 3E® 库已更新,以确保将来能检测到这些化合物。还向西米德兰兹监狱组报告了经过处理的 Itemiser 3E® 数据的趋势和影响。这项研究直接使西米德兰兹监狱组和 Rapiscan Systems Ltd. 受益,预计这项研究的延续可以扩展到全国范围。
