Since November 2018, the ketamine analog fluorodeschloroketamine (FDCK) has appeared in Hong Kong forensic cases. A retrospective study of drug seizures and driving-under-the-influence cases up to December 2019 found 74 drug seizure cases (151 items) and 6 drug driving cases. Most seized items contained only FDCK (about 67%) or a mixture with ketamine (about 28%), with purity similar to ketamine seizures. In drug driving cases, blood FDCK concentrations ranged from below 0.002 to 1.1 μg/mL, and other psychoactive substances were also present. The two cases with highest FDCK blood levels (1.1 and 0.87 μg/mL) may have contributed to impairment, though other drugs complicate interpretation.
