Figure 9: Number of deaths from drug misuse by registration year and occurrence year, 1993 to 2015

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. More details can be found in the Quality and Methodology Information report.
Figures only include deaths that were registered by 31 December 2016. 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 2015 will be an underestimate.
Deaths of persons usually resident in England, based on boundaries as of May 2017.
