Illicit drugs are big business. They are one of the main profit-generating activities of organised crime and are estimated to represent around one-fifth of global crime proceeds. ‘EU Drug Markets: In-depth analysis’ is the fourth comprehensive overview of illicit drug markets in the EU by the EMCDDA and Europol and takes a broad view of these markets from production and trafficking, to distribution and use. Designed as a series of modules, each focuses on the market for a particular drug.
