Cannabis was revealed to be the most-consumed drug in the city overall, although the suburban district of the EU-7 region on the study's map was the biggest consumer of the herb.
Meanwhile, the districts of EU1, EU6 and EU9 were reported as the largest users of heroin.
Heroin was the second most-used substance in the city, and an overwhelming 60 percent of patients seeking help for addiction recovery struggled with heroin addiction, the study reported.
Istanbul was revealed to host the largest population of in-house addiction recovery patients with 22.5 percent of the national sum residing in the metropolitan city.
Istanbul was also reported to be the second-largest consumer of heroin after New York, while the city ranked second below Barcelona for the total amount of substances consumed.
Meanwhile, an analysis of police data showed that Istanbul has become a hub of drug trafficking, with almost nine million tabs of MDMA being recovered in the city in 2019 alone, a number that tops the total for Europe as a whole.
