This year 3 of Ibiza's main clubs (Amnesia, Bora Bora and DC-10) were closed down in the opening month of the club season in a bid by authorities to force them to tackle drug-dealing and consumption among clubbers. How effective has this been and how important is drug taking to the Ibiza clubbing experience? Will a serious clampdown effect tourism? How difficult is it for the police to deal with the drug situation and are they understaffed to tackle it?
