In Japan, the most common illicit drug is methamphetamine. It is possible to trace the origin of this drug by analyzing its organic and inorganic impurities and/or byproducts using several methods, such as GC, GC/MS, and inductively coupled plasma-mass spectrometry (ICP-MS). As reported here, one other method includes comparison of the striation lines of polymer sheet layers from packaging using a polarized light method. Other alternative methods include analyzing the heat sealer pattern, layer thickness surface characteristics, and/or components of polymer sheet layers using infrared spectroscopy. Several of these alternative methods were used to analyze the origins of 29 packages confiscated from three regions over a 1000 km distance in Japan. Results indicated that packages seized from different regions had some polymer sheet layers which contained striation lines and heat sealer patterns that were similar.
在日本，最常见的非法药物是甲基苯丙胺。通过使用气相色谱（GC）、气相色谱-质谱联用（GC/MS）和电感耦合等离子体质谱（ICP-MS）等多种方法，分析其有机和无机杂质及/或副产物，有可能追踪这种药物的来源。如本文所报道，另一种方法包括使用偏振光法比较包装中聚合物片层的条纹线。其他替代方法包括使用红外光谱分析聚合物片层的热封图案、层厚表面特征及/或成分。这些替代方法中的几种被用于分析从日本相距1000多公里的三个地区查获的29个包装的来源。结果表明，从不同地区查获的包装中有一些聚合物片层包含相似的条纹线和热封图案。
