Cannabis classification in the United Kingdom

Cannabis classification in the United Kingdom refers to the class of drugs, as determined by the Misuse of Drugs Act 1971, that cannabis is placed in. Between 1928 and 2004 and since 2009, it has been classified as a class B drug. From 2004 to 2009, it was a class C drug. At present, it is a class B, with very limited exceptions.

Drug policy (including Cannabis classification) has been a contentious subject in UK politics. A number of senior Scientific advisors have objected the transfer back to class B, notably Professor David Nutt and John Beddington considered the move politically motivated rather than scientifically justified.^[1]
