A drug that users may mistakenly think is MDMA (ecstasy) powder resulted in a number of people being admitted to hospital in June.
NSW Health has warned that the drug — known as 25C-NBOMe (N-Bomb) — is a potent hallucinogenic and in Sydney had been misrepresented as MDMA. A stimulant, 4-fluoroamphetamine, has also been detected with the NBOMe.
The NBOMe drugs, which are synthetic hallucinogens used in biochemistry research, can cause vivid hallucinations, violence, fever, fear, agitation, detachment from reality and depersonalisation. The combined effects can lead to accidents and harm to self and others.
NSW Health said the drugs were potent and could be life-threatening.
The current cluster in NSW appears to be a light brown powder. NBOMe drugs are usually found in the form of blotting paper, liquid and tablets. They can also be misrepresented as LSD.
