A recent report by the European Drug Agency (EUDA) reveals a significant surge in cocaine levels in the wastewater of Barcelona, which tripled in 2025 compared to the previous year. The report indicates that while cocaine surged in Barcelona, it also saw a doubling in Lleida and a 65% increase in Santiago de Compostela, marking alarming trends in drug consumption across these Spanish cities. Conversely, Castellón witnessed a 12% decrease in cocaine levels, highlighting a varied landscape of substance use throughout the country.

The findings come from a comprehensive study that analyzed wastewater samples from 115 cities across 25 countries, including 23 in the European Union, Norway, and Turkey. This international collaboration aims to monitor drug consumption patterns through wastewater analysis, providing critical insight into public health and substance abuse issues. The report also noted an increase in ketamine presence, contrasting with a 12% drop in MDMA levels, indicating shifting preferences among drug users.

These findings underscore the rising challenges posed by substance abuse in urban areas, necessitating a coordinated response from local authorities to address the growing trend of cocaine usage. The data could inform public health interventions, promote awareness about drug use, and facilitate a more comprehensive understanding of the drug landscape in Spain and beyond, particularly as policymakers grapple with the implications for community health and safety.
