Between December 20th and 21st, tests of the water at Örebro's sewage treatment works were sent to Karolinska Institute for analysis, which suggested that about 4,800 people whose waste was processed in the sewage system were using cannabis at the time of the test. That number of people amounts to about 4 percent of the total number who use the system, however SVT notes that the results of the analysis have not been entirely confirmed yet.
Rasmus Persson (Center Party), the municipal commissioner with responsibility for social welfare, and the chair of the crime prevention council in Örebro, told SVT that they decided to run these tests in order to get a better idea of the drug usage going on in Örebro.
The plan is to share the results with authorities and organizations that are involved in trying to prevent crime.
Sören Svensson, who works for the Örebro crime prevention council, said, "The opportunity to analyze the water gives an overview of the situation and gives us a better tool for evaluating and following up on our efforts to reduce drug use." He added that, in theory, they could even measure drug usage in specific neighborhoods.
