In March 2023, we tested a number of substances of particular health concern. In addition to some (very) high-dose ecstasy tablets, we analysed a sample submitted for analysis as MDMA for the presence of cathinones 3-CMC and iso-3-CMC was detected. This combination of cathinones was also identified in two samples submitted for analysis as 3-MMC. One sample submitted for analysis as speed contained the new psychoactive substance instead of the expected amphetamine 2-Fluromethamphetamine (2-FMA). A cannabis sample showed the synthetic cannabinoid JWH-210 .
