The 40-year history of the open cannabis trade on “Pusher Street” in the heart of the Christiania neighbourhood of Copenhagen could be over as the city’s mayor said she was willing to shut it down over the commune’s fears about rising gang violence. Ever-worsening violence in the “green light” district, as organised criminal gangs have moved in and vied for dominance, has prompted growing concerns over residents’ safety. The mayor of Copenhagen, Sophie Hæstorp Andersen, has now warned in an interview with the Ekstra Bladet newspaper that the violence has to end and offered to close Pusher Street’s drug trade down if the 1,000 people living in the Christiania commune agree.
