An urgent public health warning has been issued after a batch of heroin contaminated with potent synthetic opioids led to one death and multiple overdoses in Southport, Merseyside. The victim died on April 13 after consuming nitazenes, a group of synthetic drugs far stronger than heroin. Eight non-fatal overdoses have also been reported across Sefton borough, with a potentially linked incident in Crosby.
Dr. Rory McGill, Sefton Council's Director of Public Health, expressed deep concern, stating: "These are deeply concerning events and our thoughts are with the families and friends affected. Nitazenes are far stronger than heroin and dramatically increase the risk of overdose, particularly when people do not know the substance is contaminated." He urged drug users to avoid using alone, use smaller amounts, carry naloxone, and call 999 immediately if overdose signs appear.
The Cheshire and Merseyside Local Drug Information System (LDIS) confirmed forensic testing identified etonitazene in the supply. The LDIS warning emphasised that synthetic opiates are extremely high risk, increasing the chance of hospitalisation or death. Users are advised to reduce dosage, wait at least two hours between doses, avoid mixing drugs or alcohol, and ensure naloxone availability.
Testing strips, available through local drug teams, can help identify adulteration, though not 100% accurately. Anyone with concerns should contact 999 or their local drug service. Health authorities, police, and treatment services are collaborating to prevent further harm.
