Dublin is among the top 20 cities in Europe for the presence of cocaine, ketamine and MDMA in its wastewater.
Sewage samples from 26 countries were analysed over a one week period as part of the largest European project monitoring illegal drug use through wastewater.
The study by the EU drugs agency found an increase in detections of MDMA, cocaine and amphetamine across Europe last year compared to 2023, while there was a drop in cannabis levels.
The data from the samples taken at Ringsend treatment plant showed Dublin was 15th among cities analysed for levels of ketamine and 19th when it came to daily averages of cocaine and MDMA or ecstasy.
The levels of cocaine detected in the capital increased during the weekend and peaked on Monday.
