The 2011-2021 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 2011-2021 report and the information paper on drug-related deaths. This report presents statistics on Northern Ireland (NI) drug-related mortality in 2021. Figures are based on deaths registered in NI that are known to be drug-related or a direct consequence of drug misuse. For data tables, please see the NISRA website.
