 The Melbourne, Australia inner-city suburbs of Richmond and Abbotsford are locations in which the use and dealing of heroin has been concentrated for a protracted time period.Research organisation the Burnet Institute completed the 2013 'North Richmond Public Injecting Impact Study' in collaboration with the Yarra Drug and Health Forum, City of Yarra and North Richmond Community Health Centre and recommended 24-hour access to sterile injecting equipment due to the ongoing "widespread, frequent and highly visible" nature of illicit drug use in the areas.During the period between 2010 and 2012 a four-fold increase in the levels of inappropriately discarded injecting equipment was documented for the two suburbs.
