At the beginning of March 2024, we tested a number of substances of particular health concern. In addition to several high- or very high doses ecstasy tablets, a sample submitted as MDMA also contained the cathinone 2-MMC (2-methylmethcathinone) identified. Two samples submitted for analysis as speed did not contain amphetamine, but 2-MMC or Cocaine. In a sample submitted as THC cannabis, the synthetic cannabinoid MDMB-4en-PINACA identified; in another one unknown substance detected. Two samples submitted as 3-MMC did not contain the expected cathinone, but instead contained 2-MMC resp. Mephedrone (4-MMC). A powder delivered as 5-MeO-MiPT turned out to be 4-FMA (4-fluoromethamphetamine) out. In addition to mephedrone, a sample submitted as mephedrone also contained Ketamine and 2-MMC. In addition to mephedrone, another sample also contained 3-CMC (Clophedrone) proven.
