Drugs are everywhere in Germany.
A study in 2012 showed a significant increase in drug-related problems in the city of Cologne.
This year the same study found an increase in problems among people in the German state of North Rhine-Westphalia, which borders France.
There, the number of drug-using people increased from 4,924 in 2014 to 9,971 in 2015, according to the report.
There are also problems in Germany’s biggest city, Hamburg.
In 2017, the Federal Criminal Police Office said the city had the most drug-affected people, with 3,891 drug users.
In a recent survey, Hamburgers were more likely to be drug addicts than people from other states, and they were more than twice as likely to use heroin.
The city also has the highest rate of heroin-related homicides in Germany, according the Federal Office for Drugs and Criminal Justice.
One of the worst cases was in 2017, when a 21-year-old man died after being injected with heroin.
In 2016, there were 9,000 drug-positive arrests in Hamburg, which is about two times as many as the city in 2015.
