NSW Health has released a warning about overdosing from using a light brown powder they thought was MDMA but was actually the psychedelic 25C-NBOMe & stimulant 4-FA (4-Fluoroamphetamine).
This combo has previously contributed to deaths and hospitalisations in multiple Australian states, including a cluster of deaths in Melbourne in 2016.

Effects to look out for:
Serious adverse effects may include vivid hallucinations, violent behaviour, fear, agitation, fever, derealisation and depersonalisation.

Know the risks:

  • 4-FA is a type of amphetamine, with effects somewhere between amphetamine and MDMA. 25C-NBOMe is a synthetic and potent hallucinogen. In combination, they enhance serious adverse effects, including potential death.
    Risk of harm is increased if you use with other substances that cause hallucinations or stimulants e.g. MDMA, cocaine or meth.
    RISK IS HIGHER IF SNORTED. Swallowing may reduce your risk.
    Don’t use alone, start small and make sure your friends know what you thought you were taking.


Harm Reduction Tips:

  • Don’t use alone and let your friends know what you think you’re taking.
    If you’re using a new batch, start out with a small dose.
    Reagents will not adequately identify this risk. However if using a Marquis reagent test, MDMA crystal should give a strong and immediate colour change to BLACK. In contrast, 4-FA + 25C-NBOMe will give either NO or VERY LITTLE colour change.

Getting Help:

  • If you see the warning signs of overdose seek help immediately from your nearest emergency department or call Triple Zero (000)
  • Start CPR if someone is not breathing.
