Public health warning: Opioid overdoses after using drugs people believed to be cocaine or methamphetamine
23 Feb 2024
NSW Health advises in the eight overdoses where samples were available, heroin was the opioid identified.
The warning follows a public health alert in November of 2023 when NSW Health reported three similar instances of overdose in people who used drugs they believed to be cocaine, which resulted in heroin overdoses.
NSW Poisons Information Centre Medical Director, Dr Darren Roberts, said drugs unexpectedly containing opioids can cause severe overdose or death.
“Opioid overdoses can quickly result from a single line or point,” Dr Roberts 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.
