(1)  As a seizure can involve more than one drug, figures for individual drug classes cannot be added together to produce totals.
(2)  Seizures from joint operations involving HM Revenue and Customs and the police are generally recorded against HM Revenue and Customs.
(3)  HM Revenue and Customs changed their data base system in 2001. Data before 2000 is not available.
