The 2010-2020 edition of Drug-related and drug-misuse deaths contains a revised version of drug-misuse deaths which makes data for NI comparable with England and Wales. More information is available from the 2010-2020 report and the information paper on drug-related deaths.
Revision notice 30 June 2022: Drug-related deaths and drug-misuse deaths in 2020 have been revised to reflect the findings of the review of suicide statistics and additional quality assurance of archived data. Revisions to already published data are minimal with the exception of ASMRs for drug-misuse deaths by deprivation quintile where a coding error was detected and corrected. The revised tables also include additional information on drug-related and drug-misuse deaths by ICD 10 code.
