In Australia, a study by the New South Wales Bureau of Crime Statistics and Research found "no significant trends in drug dealing or possession since the opening of the injection room five years ago," according to this story in the Sydney Morning Herald. However, the reasons why sound a cautionary note for those advocating such facilities in the United States.

The bureau's director, Don Weatherburn, said police tactics had helped to keep crime down in Kings Cross.

"Police deserve credit for stopping any increase in crime as a result of the way they have used their 'move on' powers, which allow them to order anyone suspected of loitering for the purpose of a drug offence to move on," Dr Weatherburn said.

In other words, this couldn't be replicated in the U.S., because an American police officer doing what the NSW police do will immediately be sued by the ACLU.
