At the end of September 2025, we tested a number of substances of particular health concern during inpatient drug checking. One sample submitted as CBD cannabis contained CBD and the synthetic cannabinoid MDMB-PINACA. Several tablets sold as ecstasy were found to contain very high doses of MDMA detected. Instead of the expected 2-MMC, one sample contained the active substance 4-BMC and in a sample submitted as 3-MMC only the active substance Ketamine found.
