"The United Kingdom (UK) consists of England, Wales, Scotland and Northern Ireland. England accounts for 84% of the UK population. A number of powers have been devolved from the United Kingdom Parliament to Wales, Scotland, and Northern Ireland, but each has different levels of devolved responsibilities.
"The Misuse of Drugs Act 1971 is the principal legislation in the United Kingdom for the control and supply of drugs that are considered dangerous or otherwise harmful when misused. This Act divides such drugs into three Classes (A, B and C) to broadly reflect their relative harms and sets maximum criminal penalties for possession, supply and production in relation to each class.
"Drugs in Class A include cocaine, ecstasy, LSD, magic mushrooms, heroin, methadone, methylamphetamine and injectable amphetamines. Class B drugs include amphetamine, cannabis and synthetic cannabinoids, synthetic cathinone derivatives including mephedrone, as well as, since 2012, pipradrol related compounds including desoxypipradrol (2-DPMP) and diphenylprolinol (D2PM) and, since 2013, methoxetamine and related compounds. Class C drugs include anabolic steroids, tranquillisers, ketamine, benzodiazepines and piperazines (such as BZP).
"Most drugs controlled under the Act are place in one of five schedules to the Misuse of Drugs Regulations 2001 based on an assessment of their medicinal or therapeutic usefulness and the need for legitimate access and their potential harms when misused.1
"The Drugs Act 2005 amended sections of The Misuse of Drugs Act 1971 and The Police and Criminal Evidence Act 1984, strengthening police powers in relation to the supply of drugs. The Police Reform and Social Responsibility Act 2011 added provisions for 12-month temporary class drug orders (TCDOs) enabling law enforcement activity against those trafficking and supplying temporary class drugs. Methoxetamine became the first drug subject to a TCDO in the UK in 2012 and, in June 2013, two groups of substances, known as 'NBOMe' and 'Benzofury' compounds (14 in total), were also placed under a TCDO."
