The main source of estimates of self-reported drug use is the British Crime Survey (BCS) but this provides information at the national and regional level only. However, the Home Office has commissioned a research study to provide estimates of the number of problematic opiate and crack cocaine users at local and national level. The results of the first year of this three-year study estimated that there were about 593 problem drug users (probable range 447 to 907) in Bexley Drug Action Team area in 2004-05. There are no comparable estimates available for previous years but this research project will produce estimates for 2005-06 and 2006-07 in the future.
