On 29th January 2004, cannabis was reclassified from a Class B to a Class C drug across the UK. As a controlled drug, production, supply and possession remains illegal.
The Misuse of Drugs Act 1971 (Modification) (No. 2) Order 2003 (S.I. 2003/3201) reclassifies cannabinol and cannabinol derivatives (previously Class A drugs) and cannabis and cannabis resin (previously Class B drugs) as Class C drugs in Schedule 2 to the Misuse of Drugs Act 1971 with effect from 29 January 2004. In addition, any substance which is an ester or ether (that is, a product) either of cannabinol or of a cannabinol derivative (previously a Class A drug) is reclassified as a Class C drug. (As a result of these changes, it should be noted that cannabis oil is subject to control under the 1971 Act as a Class C drug.) The Order, like the Act it modifies, applies to the United Kingdom.
