Dear colleagues,
The Belgian Early Warning System Drugs (BEWSD) at the Scientific Institute of Public Health (WIV-ISP) was informed of the analysis of two ecstasy tablets containing a high amount of MDMA.
These tablets were analysed in the framework of the Modus Fiesta drug testing service in Brussels.
The tablet characteristics can be found in the table below, together with pictures of the tablets.

The BEWSD would like to draw your attention to these tablets, and would like 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.
Please inform your networks, and don’t hesitate to contact us if you receive signals about similar tablets.
Kind regards,
Dr. Apr. Peter Blanckaert
