This publication contains the number of drug seizures made and quantity of drugs seized.
In Home Office Statistical Bulletin 12/12 the numbers of seizures made are affected by police activity and changes in recording practices and police powers, such as the introduction of cannabis warnings. Therefore, the number of drug seizures made and quantity of drugs seized should not be taken as measures of drug prevalence in England and Wales. This is addressed in the Drug Misuse Declared publications, based on results from the Crime Survey for England and Wales.
There were 216,296 drug seizures by the police and the UK Border Agency (UKBA) in England and Wales in 2011/12, a two per cent increase on 2010/11.
