Investigation of fatal injured drivers from traffic accidents, drink driving and drug driving cases in Hong Kong revealed that increase usages of methamphetamine, cocaine and zopiclone were observed, and Ketamine was the most frequently detected drug in fatally injured drivers. Expand
Prevalence of drugs of abuse found in testing of illicit drug seizures and urinalysis of selected population in Hong Kong.
Ketamine, methamphetamine and heroin were the three most commonly encountered abused drugs through laboratory testing during the study period, and identification of ketamine was shown to decline continuously in both illicit drug testing and urinalysis while there was substantial increase in detection of MA.

The study reports the detection of a newly emerged drug, deschloro-N-ethyl-ketamine (2-oxo-PCE), an analog of ketamine, through forensic drug and toxicological examinations of exhibits from drug… Expand
Prevalence of drugs of abuse found in forensic testing of illicit drug seizures and urine samples from offenders/probationers in Hong Kong: A 3-year update.
While MA was the most prevalent drug in the period, cases found with cocaine and cannabis increased steadily over the past 3 years and a rising trend was noted for cases identified with new psychoactive substances (NPS) in illicit drug seizures from an average of 87 cases/ year in 2011-2015 to 211 cases/year in 2018 although NPS cases still contributed to less than 5% of overall drug seizures.
