Rising synthetic opioid crisis

The true scale of fatalities involving synthetic opioids known as nitazenes is likely far greater than current official counts suggest, this is according to research from King’s College London published in Clinical Toxicology. While the National Crime Agency (NCA) recorded 333 fatalities involving nitazenes in 2024, researchers emphasize this figure almost certainly underrepresents reality. Toxicologists have raised concerns that nitazenes degrade rapidly in postmortem blood samples, reducing their detectability during routine forensic analyses. 

Using advanced modelling techniques and data from the UK National Programme on Substance Use Mortality (NPSUM), the research team estimated that in Birmingham alone during 2023 there was a 33 percent excess in drug-related deaths unaccounted for by current nitazene detection methods. This discrepancy strongly suggests that a significant proportion of fatal overdoses are not being linked to nitazenes due to analytical limitation
