At the end of November / beginning of December 2023, we tested a number of substances of particular health concern. Three ecstasy tablets contained the new psychoactive substance instead of the expected MDMA 3-FEA (3-fluoroethamphetamine). In two samples submitted as cannabis, the synthetic cannabinoid MDMB-4en-PINACA was found, in one of them additionally MDMB-INACA. A sample submitted for analysis as 5-MAPB did not contain the expected entactogen, but the dissociative new psychoactive substance 3-MeO-PCP. In a sample submitted as JWH-210, another cannabinoid was detected in addition to the expected synthetic cannabinoid: EDMB-PINACA.
