(1)  Some of the quantities differ slightly from HM Revenue and Customs' own figures because of  differences in the treatment of information, mainly revisions to weights, which became available after publication.
(2)  Seizures from joint operations involving HM Revenue and Customs and the police are generally recorded against HM Revenue and Customs.
(3)  As a seizure can involve more than one drug, figures for individual drugs cannot be added together to produce totals.
(4) Drugs are seized in a variety of forms and where possible, for the purpose of this table, amounts have been converted to weigts (kg). Seizures of unspecified quantities are not included.
(5) GHB became a controlled drug in 2003.
