NSW Health Issues Public Warning on High-Dose MDMA and Ketamine Analogues
27 Nov 2025
The substances were identified through the NSW Government’s drug checking trial at the Strawberry Fields festival in Tocumwal, southern NSW. Multiple MDMA tablets and capsules contained higher doses than typically seen, while ketamine analogues were found in white powders and crystalline forms.
No festival attendees required hospitalisation, though one public warning was issued on-site regarding the MDMA tablets. NSW Health cautions that these substances are still in circulation. Drug checking services will also be available at the upcoming Hypersonic music event at Sydney Showground.
Risks of High-Dose MDMA
Dr Hester Wilson, Chief Addiction Medicine Specialist at NSW Health, highlighted the dangers of high MDMA intake, particularly in hot environments:
-
Severe agitation and overheating
-
Seizures or fits
-
Irregular heart rhythm
-
Potentially fatal outcomes
Risks are heightened if MDMA is combined with stimulants like amphetamines or cocaine, or if multiple tablets are consumed in a short period. Variability in MDMA content, even within the same batch, increases unpredictability. Festival-goers are advised to take breaks, seek shade, and stay hydrated.
Ketamine Analogues
Ketamine-like substances mimic ketamine’s chemical structure but can produce stronger dissociation or hallucinations. They may also cause seizures and irregular heart rhythm, with greater risks if combined with depressants (alcohol, GHB, benzodiazepines, opioids) or stimulants.
Safety Advice
NSW Health urges anyone who feels unwell after taking drugs to seek immediate medical help. Calling Triple Zero (000) is encouraged and will not result in legal repercussions.
At festivals, trained medical staff and peer volunteers from programs like DanceWize NSW are available to provide support.
