​​The Belgian Early Warning System Drugs (BEWSD) at the Scientific Institute of Public Health (WIV-ISP) would like to report the identification and analysis of several highly dosed MDMA tablets. 

These tablets were analysed in the framework of a BEWSD study during several summer festivals between July and end of September. Some tablets were analysed by the National Institute for Criminalistics and Criminology (NICC), and are included as well.

The tablets  shown contain more than 200mg of MDMA base (picture 1). The second picture contains tablets with a MDMA base content of 150 to 200 mg. All further characteristics can also be found in the pictures.

The BEWSD would like to draw your attention specifically to those results. We take this opportunity to remind you that the majority of ecstasy tablets currently circulating are highly dosed, sometimes containing dosages of up to 300 mg MDMA base (the amount of MDMA present in an ecstasy tablet can only be determined using laboratory analysis).

Symptoms of an MDMA overdose are characterised by heavy sweating, tremor, dry mouth, nausea, vomiting, elevated blood pressure and heart rate, paranoia and hyperthermia. In severe cases a serotonin syndrome can occur, resulting in an often fatal hyperthermia.
