"Figure 11: Number of deaths from drug misuse, by registration year and occurrence year, 1993 to 2013","" "England and Wales","" "","" "Notes","1. Cause of death was defined using the International Classification of Diseases, Ninth Revision (ICD-9) for the years 1993 to 2000 and Tenth Revision (ICD-10) from 2001 onwards (see Background notes 4 and 5). 2. Figure 11 only includes deaths that were registered by 31 December 2014. Due to the length of time it takes to complete a coroner’s inquest, it can take months or even years for a drug-related death to be registered, so figures for deaths occurring in 2013 will be an underestimate. 3. Figures for England and Wales include deaths of non-residents.
