Poput Turske, i Srbija se smatra važnom tranzitnom zemljom za narkotike i ostale droge na ruti koja se koristi za prijenos heroina, kokaina, marihuane i sintetičkih droga u centralnu i istočnu Evropu.
Like Turkey, Serbia is seen as a major transit country for narcotics and other drugs on the route used for moving heroin, cocaine, marijuana, and synthetic drugs to Central and Western Europe.
