Analysis of Milk Tea as a New Mixed Drug Substance in China

Among the popular mixed drugs in China, the oral solution shenxianshui and the floury drug milk tea have recently emerged. In 2014, 123 bags of milk tea included in 14 cases were tested qualitatively and quantitatively, and the test results provided a basis for drug detection, prosecution, and sentencing. More than two drug components were detected in milk tea, which was characterized as a fragrant beige, yellow, or brown powder. The detection rates of methylamphetamine (MA), 3,4-methylenedioxymethamphetamine (MDMA), and ketamine in milk tea were 36.6%, 50.4%, and 76.4%, respectively, and the concentrations of MA, MDMA, and ketamine were 0.2–5.1, 3.2–30.1, and 0.8–176.3 mg/g, respectively, in quantitative testing.
