Abstract
Facing the problem of backlogs in the forensic laboratories, the field of illicit drugs analyses has recently seen the development of different types of portable devices. Their main purpose is to be used directly by the police in order to reduce the number of specimens that are sent to the laboratories. Several portable devices have shown promising results. To avoid misuses, the added value of these devices should be explored, in order to establish "good practices" and keep the communication channels open between the police and the laboratories. Adapting sampling procedures around the use of portable devices allows for real-time qualitative and quantitative data. Forensic scientists can therefore rapidly assess whether every specimen in a seizure contain illicit drugs and if the seizure is composed of specimens showing different composition. Based on these information, forensic scientists can proceed to an intelligence-led sampling and prioritise specimens that would require further analyses. Additionally, the availability of more analysis data can strengthen the confidence in the reporting of the sampling process and the analyses results. Various scenarios have been tested in an operational context at the Geneva Cantonal Police Force using an ultraportable NIR device. The focus was oriented on sampling issues and the intelligence produced. Results indicate a great potential to detect the different classes within a seizure and therefore to ensure a representative sampling for further analyses.
