Weed still EU's most-used narcotic
Marijuana continues to be the EU's most commonly used drug, with almost 79 million citizens estimated to have tried it at some point in their lives.
That is almost a quarter of the EU's adult population and compares with 15.6 million who have tried cocaine, the second most popular drug.
The annual European Drug Report said marijuana accounts for 80pc of drug seizures on the continent and 60pc of all reported drug law offences.
Crime groups are becoming more deeply involved in marijuana production and trafficking, making it a drug of increasing importance for law enforcement agencies, the report said.
