The Health Service Executive is launching a new wastewater testing programme to track illicit drug consumption across Ireland, with analysis set to begin by March 2026.
The three-year contract, valued at €480,000, will provide health officials with objective, real-time data on drug market trends and consumption patterns. The initiative forms part of an early warning system operated by the HSE’s National Social Inclusion Office.
Unlike traditional methods that rely on garda seizure statistics, user surveys and treatment figures, wastewater analysis offers a more comprehensive picture of actual drug use in communities. Scientists will test samples from wastewater treatment plants to measure levels of illicit substances and their metabolites excreted in urine.
The HSE said this non-invasive approach can identify the true spectrum of drugs being consumed, rather than depending on individuals’ recollections. The data will help inform policy decisions and local responses to drug issues.
“This provides a non-invasive, near-real-time analysis of drug use within the area served by the sewer network,” the HSE stated in tender documents.
The programme, costing up to €160,000 annually, aims to establish regular surveillance updates and potentially develop into a permanent national monitoring system after the initial three-year period.
