NSW - Public drug warning: High dose MDMA (ecstasy) tablets recently found in NSW - also containing a synthetic cathinone

Published on March 6, 2025

Skull shaped tablets with MYBRAND marking have been found containing high dose MDMA and a synthetic cathinone, dipentylone (also known as N,N-dimethylpentylone).

The risk of harm is increased when MDMA is taken with other stimulants including synthetic cathinones, amphetamines or cocaine.

Pink-orange: 182-185mg MDMA + dipentylone

Blue: 162mg MDMA + dipentylone

Yellow: 151 mg MDMA​

Other recently tested skull shaped tablets with MYBRAND marking have contained MDMA with ketamine or 2'-fluoro-2-oxo-PCE (a ketamine analogue, also known as 2F-NENDCK, or 2-fluoro-N-ethylnordeschloroketamine).

Tablet appearance is not a reliable indicator of drug contents.

Know the risks

  • Synthetic cathinones are stimulants that may have similar effects to MDMA and other amphetamines. There is limited information on the specific effects of dipentylone.
  • MDMA tablets are often pooly manufactured and the amount of MDMA and other substances in a tablet can vary a lot, even within the same batch.
  • You are at increased risk of harm if you:
    • Take multiple MDMA (ecstasy) tablets or capsules
    • Take a higher-dose MDMA tablet or capsule
    • Take MDMA in a hot environment like a music festival or indoor dance party
  • The time from taking the drug to feeling any effect can vary between people and tablets.  If it's not working, don't re-dose.
  • High dose MDMA use has been linked to death and other serious harms.

Effects to look out for

  • Feeling really hot and sweaty
  • Racing heart/pulse or light-headedness
  • Rigid muscles (e.g. difficulty walking), uncontrolled repetitive movements, seizures
  • Confusion or agitation, feeling aggressive, difficult to rouse or unconscious
  • Vomiting

If you or others experience these symptoms after taking MDMA, get help immediately.

Getting help

If you or your friends see the warning signs of overdose:

  • Seek help immediately from your nearest emergency department or call Triple Zero (000). You won't get into trouble for seeking medical care.
  • Start CPR if someone is not responsive.
