Drugs controlled by the UK Misuse of Drugs Act

Drugs controlled by the United Kingdom (UK) Misuse of Drugs Act 1971 are listed in this article.

These drugs are known in the UK as controlled drugs, because this is the term by which the act itself refers to them. In more general terms, however, many of these drugs are also controlled by the Medicines Act 1968, there are many other drugs which are controlled by the Medicines Act but not by the Misuse of Drugs Act, and other substances which may be considered drugs (alcohol, for example) are controlled by other laws.

The Misuse of Drugs Act sets out three separate categories, Class A, Class B, and Class C. Class A drugs represent those deemed most dangerous, and so carry the harshest punishments. Class C represents those thought to have the least capacity for harm, and so the Act demands more lenient punishment. In reality the potential harm has little bearing on the class,<ref name='nutt's paper'>Nutt, Prof David J; Leslie A King PhD, Lawrence D Phillips PhD (6 November 2010). "Drug harms in the UK: a multicriteria decision analysis". The Lancet 376 (9752): 1558–1565. doi:10.1016/S0140-6736(10)61462-6. PMID 21036393. Retrieved 2012-02-08. "Alcohol, heroin and crack were found to be most harmful, while LSD, Buprenorphine and psilocybin mushrooms were found to be least harmful."  Cite uses deprecated parameters (help)</ref> which has led to dissatisfaction with drug laws.^[1]

Being found in possession of a drug on this list is dealt with less seriously than would be if it were deemed that there is intent to supply (even without payment) the drug to others. Possession with intent to supply carries a maximum penalty of life imprisonment.

With regard to lawful possession and supply, a different set of categories apply which are set out in the Misuse of Drugs Regulations 2001 (as amended). This sets out five schedules each with their own restrictions. Schedule 1 contains substances which allegedly have no medicinal value such as hallucinogens and their use is limited primarily to research, whereas schedules 2-5 contain the other regulated drugs. This means that although drugs may fall into the category of Class A/B/C, they may also fall into one of the schedules for legitimate medicinal use. For example, morphine is a Class A drug under the Misuse of Drugs Act 1971, but when lawfully supplied falls under the category of a Schedule 2 controlled drug.

Substances may be removed and added to different parts of the schedule by statutory instrument, provided a report of the Advisory Council on the Misuse of Drugs has been commissioned and has reached a conclusion, although the Secretary of State is not bound by the council's findings. This list has in practice been modified a great number of times, sometimes removing substances, but more commonly adding some; for example, many benzodiazepines became Class C drugs in 1985, and many cathinones became Class B drugs in 2010.

Glossary of terminology used in this list anabolic steroids — hormones that build muscle tissue benzodiazepines — a class of sedative/ anxiolytic drugs cannabinoids — drugs that bind to cannabinoid receptors arylcyclohexamines — dissociatives which act on the NMDA receptors opioids — Drugs that bind to opioid receptors phenethylamines — psychedelics based on phenethylamine sedatives — drugs that lower arousal stimulants — drugs that heighten arousal tryptamines — psychedelics based on tryptamine

(f) 1–benzylpiperazine or any compound (not being 1–(3–chlorophenyl)piperazine or 1–(3–chlorophenyl)–4–(3–chloropropyl)piperazine) structurally derived from 1–benzylpiperazine or 1–phenylpiperazine by modification in any of the following ways

(i) by substitution at the second nitrogen atom of the piperazine ring with alkyl, benzyl, haloalkyl or phenyl groups;

(ii) by substitution in the aromatic ring to any extent with alkyl, alkoxy, alkylenedioxy, halide or haloalkyl groups;

2. Any stereoisomeric form of a substance for the time being specified in paragraph 1 of this Part of this Schedule [not being phenylpropanolamine.]

3. Any salt of a substance for the time being specified in paragraph 1 or 2 of this Part of this Schedule.

Derivatives and analogues

The act contains several references to "derivatives" of compounds but the extent of this term is not fully clarified. Where unspecified it is thought to indicate derivatives which can be made from the specified compound in a single synthetic step, although such a definition would indicate that alkyllysergamide analogues would be uncontrolled. Where the derivatives are specified to be "structural derivatives" there is precedent that the statute applies whenever the structure could be converted to the specified derivatives in any number of synthetic steps.^[18]
