We are sharing an urgent alert issued by the Cheshire and Merseyside Local Drug Information System (LDIS). Please read this carefully and share it with anyone who may need it.

If you use drugs

There is a contaminated batch (or batches) of heroin circulating in and around the Wirral and Southport areas, with similar reports from other parts of Cheshire and Merseyside.

A number of people have overdosed. Some needed hospital treatment. At least two people have died.

Forensic testing has found a synthetic opioid called etonitazene in the supply. Synthetic opioids are extremely dangerous and significantly increase the risk of overdose and death.

Using these drugs could put you in hospital or kill you.

What you can do to stay safer

  • Carry naloxone: Make sure you have naloxone with you and know where it is. This applies even if you do not use heroin or other opioids.
  • Do not mix drugs: Mixing drugs, including alcohol, increases your risk of overdose.
  • Go low and slow: Start with a very small amount. Wait at least two hours before taking any more.
  • Do not use alone: Use where someone else is present who can give naloxone if needed.
  • Use drug-checking strips: These are not 100% accurate, but strips available from your local drug team can help identify whether your drugs may contain a more harmful substance.
  • Call 999: If you or someone else needs urgent help, call 999 immediately.
  • Contact Wirral Ways: If you have any concerns, get in touch with us. We are here to help, not to judge.

If you support someone who uses drugs

If someone you care about uses heroin or other opioids, this alert is relevant to you too.

What you can do

  • Get naloxone: Naloxone reverses an opioid overdose and can save a life. You can get it free from Wirral Ways. Ask us how to use it if you are not sure.
  • Know the signs of overdose: Look for: not responding, slow or stopped breathing, blue or grey lips, pinpoint pupils, gurgling or snoring sounds.
  • Call 999 immediately: If you think someone has overdosed, call 999 straight away. Give naloxone if you have it and put the person in the recovery position while you wait for help.
  • Share this post: Pass this information on to anyone who might need it.
  • Talk to us: If you are worried about someone, or want advice on how to support them, contact Wirral Ways. Our team can help.
