Introduction
An important element of the UNODC International Quality Assurance Programme (IQAP) is the implementation of the International Collaborative Exercises (ICE). The exercises allow laboratories, from both developing and developed countries to continuously monitor their performance in drug testing on a truly global scale. This report provides information on analytical results of laboratories participating in the Seized Materials (SM) group. In order to maintain confidentiality, the participating laboratories have been assigned random “Web Codes”, which change every round. The analytical results returned by laboratories participating in ICE are evaluated by UNODC and a confidential report is provided to each laboratory on its own performance. The overall analytical results are reviewed by the UNODC’s International Panel of Forensic Experts which oversees the implementation of these exercises, and offers guidance and support in addressing relevant quality issues. The exercises provide an overview of the performance and capacity of participating laboratories and enable UNODC to tailor technical support in the laboratory sector for greatest impact. The ICE programme is a UNODC mandated activity and is implemented through regular budget funds and through the UNODC Global Scientific and Forensic Programme – Support Project (GLOU54), which operationalizes the forensic aspects of the UNODC Thematic Programme on Research, Trend Analysis and Forensics"
Comments from the International Panel of Forensic Experts
Participation of Laboratories In the 2018/2 round of the ICE programme, results were submitted within both the Seized Materials (SM) and Biological Specimens (BS) test groups by 231 laboratories in 77 countries. Within the BS test group, results were submitted by 82 laboratories from 46 countries and within the SM test group, there were 194 participating laboratories from 69 countries.
Qualitative Analysis The analytical technique most commonly used for screening of test samples in the BS test group were immunoassays (67% of participants), while GC-MS (78%) was the most commonly used technique for identification/confirmation of the components in the test samples. The results for the qualitative identification of the sample components in the BS test group, the number of false positive/negative results and the analyses not performed are shown in table 1.

In general, the number of false positives reported for the four test samples has increased slightly from previous round. 6 laboratories found reported amfetamine for BS-2 (MDA). The number of false negative results and analyses not performed for buprenorphine and mephedrone in BS-1 and BS-3 respectively are concerning. Laboratories reporting false positive or false negative results should investigate the reasons for this and corrective actions should be taken as soon as possible in order to continuously improve performance. ICE participants are reminded that test samples can contain any of the substances in the ICE menu and as such if methods are available, all substances should be considered. Quantitative Analysis The test samples in the BS group for the 2018/2 round of ICE contained a total of five components and 38 (46%) of participating laboratories performed quantification. Of these laboratories, it is encouraging to note that 78% of laboratories quantified at least two components and 52% performed quantification of at least three test sample. LC/MS(/MS), used by 57% of participants, was the most commonly used technique for quantitation, followed by, GC-MS which was used by 55% of participants. z-scores obtained by participants in quantification are shown in the table below (percentage + no. of labs indicated).

13% (3) 0% (0) 6.5% (2) 15% (3) 8% (3)
Table 2. Quantitative performance of participants in the 2018/2 round of ICE.
According to the recommendations in ISO 13528:2005, an unsatisfactory z-score is considered to give an action signal and a questionable z-score is considered to give a warning signal. A single action signal or warning signals in two successive rounds shall be taken that an anomaly has occurred that requires investigation. Participants with z-scores outside acceptable limits should review their quantification procedures as soon as possible. Of the 4 laboratories that obtained a single action or warning signal in ICE rounds 2017/2 and 2018/1, all 4 participated in 2018/2 and 2 of these improved their performance in quantitation. The laboratories IN9RUR and YCH0DH also obtained action or warning signals in 2018/2. The following laboratories obtained a single action signal or warning signal in the two successive rounds of 2018/1 and 2018/2 and shall take this as anomaly, which requires further investigation: A0OXAA, IN9RUR and YCH0DH. Laboratories that need to perform quantitation routinely are encouraged to participate regularly in external proficiency testing or collaborative exercises such as the ICE programme. This will enable laboratories to assess the quality of their quantitative methods through the z-score values obtained. Laboratories reporting false positive or false negative results should investigate the root causes and corrective actions taken promptly in order to continuously improve performance. Participation in the ICE programme also helps in monitoring the effect of corrective actions. UNODC would like to acknowledge the valuable contribution of the Chemical Metrology Laboratory of the Health Sciences Authority, Singapore, for the provision of specific software used for the quantitative statistical calculations in the ICE programme.

New Psychoactive Substances (NPS) reported by laboratories participating in the 2018/2 round of the ICE programme During the 2018/2 round of ICE, participating laboratories provided information on NPS that had been identified in their laboratories. In total there were 175 reports of 116 substances. The most commonly reported substances were synthetic cannabinoids (35%) followed by synthetic cathinones as shown in figure 1.
Figure 1. NPS reported by ICE laboratories during the 2018/2 round of ICE
In terms of the mode of action of the NPS reported by ICE participants, the predominant substances reported were synthetic cannabinoid receptor agonists (SCRA) (35%), while 34% were stimulants as shown in figure 2.

Z-Score Report per Sample per Substance: Round: 2018/2 Substance: BS-1; Buprenorphine
Z-scores can be interpreted by participants in line with ISO 13528:2005, section 7.4.2 and ISO/IEC guide43-1:1997(E) as follows:
IzI < 2 = satisfactory
2 ≤ IzI ≤ 3 = questionable
IzI > 3 = unsatisfactory
According to the recommendations in ISO 13528:2005, an unsatisfactory z-score is considered to give an action signal and a questionable z-score is
considered to give a warning signal. A single action signal or warning signal in two successive rounds shall be taken that an anomaly has occurred
that requires investigation.

Z-Score Report per Sample per Substance: Round: 2018/2 Substance: BS-1; Norbuprenorphine
Z-scores can be interpreted by participants in line with ISO 13528:2005, section 7.4.2 and ISO/IEC guide43-1:1997(E) as follows:
IzI < 2 = satisfactory
2 ≤ IzI ≤ 3 = questionable

Z-Score Report per Sample per Substance: Round: 2018/2 Substance: BS-3; Mephedrone
Z-scores can be interpreted by participants in line with ISO 13528:2005, section 7.4.2 and ISO/IEC guide43-1:1997(E) as follows:
IzI < 2 = satisfactory
2 ≤ IzI ≤ 3 = questionable
IzI > 3 = unsatisfactory
According to the recommendations in ISO 13528:2005, an unsatisfactory z-score is considered to give an action signal and a questionable z-score is
considered to give a warning signal. A single action signal or warning signal in two successive rounds shall be taken that an anomaly has occurred
that requires investigation.

Z-scores can be interpreted by participants in line with ISO 13528:2005, section 7.4.2 and ISO/IEC guide43-1:1997(E) as follows:
IzI < 2 = satisfactory
2 ≤ IzI ≤ 3 = questionable
IzI > 3 = unsatisfactory
According to the recommendations in ISO 13528:2005, an unsatisfactory z-score is considered to give an action signal and a questionable z-score is
considered to give a warning signal. A single action signal or warning signal in two successive rounds shall be taken that an anomaly has occurred
that requires investigation.
