Background
In 2022, the HSE, in partnership with Merchants Quay Ireland, collected 165 used syringes from the Dublin and Midlands regions during September and October. Residual drugs were extracted from these syringes and the data obtained were used to compare drug trends from the two regions.
The Syringe Analysis Programme is the first of its kind in Ireland and enables the HSE to identify temporal and geographical trends annually as part of its emerging drug trend monitoring. Analysis of 235 drugs and metabolites was performed using liquid chromatography–mass spectrometry.
These analyses spanned a wide range of substances, such as opiates (including new synthetic opioids), benzodiazepines, amphetamines, cocaine, new psychoactive substances (NPS), Z-drugs, gabapentinoids, ketamine, and various cutting agents. In 2023, the HSE published a report1 detailing the findings from the 2022 analysis programme; it also compared 2022 programme results to findings from a syringe analysis programme conducted in 2021. The main findings are discussed below.
