Multiple opioid overdoses following use of cocaine
Source: NSW Health
Drug sold as: Cocaine
Reason for concern: Opioid overdose resulting in hospitalizations
Six people recently presented to hospitals in Sydney and Western NSW with opioid overdoses after using what they thought was cocaine.
Know the risks
- Opioids such as heroin may be sold as or found in cocaine, methamphetamine and MDMA.
- Small amounts of opioids can cause life-threatening overdose.
- This risk is higher in people who have never or rarely used opioids.
- You cannot always tell the difference between heroin, cocaine and methamphetamine by appearance.
- The risks of overdose are increased if you:
- use a high dose, or re-dose when you are not getting the desired effect.
- use with other drugs (for example alcohol, benzodiazepines, ketamine, GHB or opioids).
- use drugs alone.
- use a new batch.
- Fentanyl and nitazene test strips do not detect heroin or many other opioids.
Effects to look out for
- Unexpected drowsiness
- Pinpoint pupils
- Loss of consciousness
- Slow breathing/snoring
- Skin turning blue/grey
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.
- Use naloxone if you have it. Call ‘000’ even if naloxone has been given.
Take Home Naloxone program
- Naloxone is a life-saving medicine that can temporarily reverse an opioid overdose. Naloxone is available in a very easy to use nasal spray, and as a pre-filled injection.
- You should carry naloxone if:
- you are using drugs in the form of a pill, powder, crystal or liquid
- you are going somewhere where drugs will be present
- If you are at risk of experiencing or witnessing an opioid overdose you can get naloxone for free without a prescription in NSW from some community pharmacies, needle and syringe programs, opioid treatment services and NUAA.
- Visit Your Room – Naloxone for participating sites and more information on take-home naloxone.
- NUAA can mail you naloxone in a discreet package. Order via their online shop or call (02) 9171 6650.
