One of the tasks of the European project entitled "Collaborative Harmonisation of Methods for Profiling of Amphetamine Type Stimulants" (CHAMP) funded by the sixth framework programme of the European Commission was to develop a harmonised methodology for MDMA profiling and the creation of a common database in a drug intelligence perspective. Part I was dedicated to the analysis of organic impurities formed during synthesis in order to investigate traffic tendencies and highlight potential links between samples, whereas this part focuses on physical characteristics of the MDMA tablets. Diameter, thickness, weight and score were demonstrated to be reliable and relevant features in this drug intelligence perspective. Distributions of samples coming from the same post-tabletting batch (post-TB) and samples coming from different post-TB were very well discriminated by using the squared Euclidean or the Manhattan distance on standardised data. Our findings demonstrated the possibility to discriminate between MDMA samples issued from different post-TB and to find out links between samples coming from a same post-TB. Furthermore, the hypothesis that most of the MDMA samples found on the international market come from the same countries was supported.
由欧盟委员会第六框架计划资助的名为“苯丙胺类兴奋剂特征分析方法的协同统一”（CHAMP）的欧洲项目的任务之一，是从毒品情报角度开发一种统一的摇头丸特征分析方法并创建一个通用数据库。第一部分致力于分析合成过程中形成的有机杂质，以调查交易趋势并突出样本之间的潜在联系，而本部分则侧重于摇头丸片剂的物理特征。从毒品情报角度来看，直径、厚度、重量和刻痕被证明是可靠且相关的特征。通过对标准化数据使用平方欧几里得距离或曼哈顿距离，来自同一压片后批次（post-TB）的样本和来自不同压片后批次的样本的分布得到了很好的区分。我们的研究结果表明，有可能区分来自不同压片后批次的摇头丸样本，并找出来自同一压片后批次的样本之间的联系。此外，国际市场上发现的大多数摇头丸样本来自相同国家这一假设得到了支持。
