As 24Sata / Reuters report, the highest levels of drug residues were found in Belgium, Spain, Portugal and the Netherlands.
The study, which was largest to date, was conducted by the Lisbon-based European drug monitoring agency EMCDDA. The study analyzed daily wastewater in the catchment areas of treatment plants serving around 54 million people in 104 European cities.
They analyzed samples collected over a one-week period between March and April last year for traces of cocaine, amphetamines, methamphetamines, MDMA/ecstasy, ketamine and cannabis and found that drug use was higher than in previous studies.
“Today’s findings, from a record 104 cities, paint a picture of a drug problem that is both widespread and complex, with all six substances detected in almost all locations”, said EMCDDA Director Alexis Goosdeel.
The results showed a “continued increase in cocaine detections,” a trend seen since 2016, and more cities reporting traces of methamphetamine.
More than half of the 66 European cities with data for 2021 and 2022 saw an increase in cocaine residues.
Ketamine was included in the analysis for the first time in 2022 due to “signs of increased availability of ketamine in Europe”. The largest amount of residues was found in waste water in the cities of Denmark, Italy, Portugal and Spain.
As for Zagreb, a decrease in cocaine consumption was recorded, and the survey showed that the people of Zagreb most often take cocaine on Fridays.
