This publication provides an overview of drug seizures made by the police (including the British Transport Police) and Border Force in the year ending 31 March 2023 in England and Wales. The data relates to all drugs controlled under the Misuse of Drugs Act 1971 (MDA) and the Psychoactive Substance Act 2016 (PSA).

The number of seizures can be heavily affected by enforcement activity as well as changes in recording practices. Annual totals of the quantity of drugs seized can be greatly influenced by a small number of large seizures. As with the number of drug seizures, any large quantity of drugs seized should not be taken as an indication of drug use prevalence or availability.
