The use of illicit addictive drugs, especially methamphetamine, is a major social problem in Thailand. In 2005, there were more than 50,000 cases of seizure of methamphetamine drug in Thailand involving over 13.5 million pills. This study classifies the tablets according to their physical properties and main chemical composition. Random samples from 100 lots of seized methamphetamine pills that had been sent to Office of Forensic Science, Royal Thai Police, in 2010-11 for chemical analysis were… Expand

The impurity characteristics of methamphetamine synthesized by Emde and Nagai method.
TLDR
This study focused on classifying seized methamphetamine samples according to the groups sorted by the types and quantities of impurities present in illicit methamphetamine samples, which are Nagai type, Emde Type, Undetermined I type, and Undetermined II type. Expand
Identification of impurities and statistical classification of methamphetamine tablets (Ya-Ba) seized in Thailand.
TLDR
For characterization and comparison of methamphetamine tablet exhibits, intensely and commonly detectable nine peaks are selected as the factor for multivariate analysis and classification of 250 analyzed exhibits into five groups and characterization of classified groups. Expand
Determination of impurities in illicit methamphetamine seized in Korea and Japan.
TLDR
Cluster analysis result showed that part of the MA samples seized in Japan might have the same origin as those seized in Korea, which means that broad-based cooperation is necessary for efficient regulation of MA. Expand
Analysis of the impurities in the methamphetamine synthesized by three different methods from ephedrine and pseudoephedrine.
TLDR
The impurities reflecting the conditions of synthesis by comparing impurity patterns of the methamphetamine samples synthesized by different methods found 10 peaks appearing in the latter part of GC chromatograms are characteristic to synthesis. Expand
Australian Federal Police seizures of illicit crystalline methamphetamine ('ice') 1998-2002: impurity analysis.
TLDR
Analysis of crystalline methamphetamine seizures captured by the Australian Federal Police at the Australian border between 1998 and 2002 identified >30 compounds associated with methamphetamine and/or its synthetic route, suggestive of ephedrine/pseudoephedrine as the main precursor of the 'ice' samples seized.

A study of impurities found in methamphetamine synthesized from ephedrine
Abstract The synthesis of methamphetamine from ephedrine via reduction with hydriodic acid is discussed. Impurities which arise from this method are identified and rationalized. The in situ formation… Expand
