NSW Health is warning of the danger of using drugs thought to be cocaine, which have resulted in four recent heroin overdoses including two deaths.

NSW Health Chief Addiction Medicine Specialist, Dr Hester Wilson said two people died after the use of substances they thought to be cocaine, while another two people have required hospitalisation.

“A heroin overdose could quickly result from a single line,” Dr Wilson said.

“It is important that people recognise the signs of an opioid overdose early and know how to respond. Opioids such as heroin can cause pin-point pupils, drowsiness, loss of consciousness, slowed breathing/snoring and skin turning blue/grey and can be life-threatening.

“One of the dangers of illicit drug supply is the strength and contents of the substance you are getting is unknown and can be inconsistent.

“Heroin and other opioids can be sold as or found in cocaine, methamphetamine, and MDMA (ecstasy). You cannot always tell the difference between these drugs by appearance.

“In light of this detection, people who use drugs such as cocaine, methamphetamine, MDMA or opioids should carry naloxone.”

If you witness someone experiencing any unexpected symptoms after using drugs, you should call Triple Zero (000) immediately or seek urgent medical attention. Naloxone should be given immediately if available.

Naloxone is an important life-saving medication that reverses the effects of opioids. It does not require a prescription and is free for anyone at risk of opioid overdose in NSW.

It is available as an easy to use nasal spray or injection from some pharmacies and other health services. For more information on the take-home naloxone program visit Your Room - Naloxone.

NUAA can mail you naloxone in a discreet package. Order via their online shop or call (02) 8354 7343.

You won't get into trouble for seeking medical care. If you feel unwell, or if your friend feels unwell, do something about it.
