Misuse Of Drugs

See also MEDICINES. Government legislation covers the manufacture, sale and prescription of drugs in the UK. As well as stating which drugs may be sold over the counter (OTC) without a doctor’s or dentist’s prescription, and those which can be obtained only with such a prescription, government regulations determine the extent of availability of many substances which are liable to be abused – see Misuse of Drugs Act 1971 (below). The Misuse of Drugs Regulations 1985 de?ne those individuals who in their professional capacity are authorised to supply and possess controlled drugs: see the schedules of drugs listed below under the 1985 regulations.

Misuse of Drugs Act 1971 This legislation forbids activities relating to the manufacture, sale and possession of particular (controlled) drugs. These are classi?ed into three grades according to their dangers if misused. Any o?ences concerning class A drugs, potentially the most damaging when abused, carry the toughest penalties, while classes B and C attract lesser penalties if abused.

Class A includes: cocaine, dextromoramide, diamorphine (heroin), lysergic acid (LSD), methadone, morphine, opium, pethidine, phencyclidine acid and injectable preparations of class B drugs.

Class B includes: oral amphetamines, barbiturates, codeine, glutethimide, marijuana (cannabis), pentazocine and pholcodine.

Class C includes: drugs related to the amphetamines, anabolic and androgenic steroids, many benzodiazepines, buprenorphine, diethyl propion, human chorionic gonadotrophin (HCG), mazindol, meprobamate, pemoline, phenbuterol, and somatropin.

Misuse of Drugs Regulations 1985 These regulations de?ne those people who are authorised in their professional capacity to supply and possess controlled drugs. They also describe the requirements for legally undertaking these activities, such as storage of the drugs and limits on their prescription.

Drugs are divided into ?ve schedules and some examples follow.

I: Almost all are prohibited except in accordance with Home O?ce authority: marijuana (cannabis), LSD.

II: High potential for abuse but have

accepted medical uses: amphetamines, cocaine.

III: Lower potential for abuse: barbiturates, meprobamate, temazepam.

IV: Lower potential for abuse than I to III. Minimal control: benzodiazepines.

V: Low potential for abuse: generally compound preparations containing small amounts of opioids: kaolin and morphine (antidiarrhoeal medicine), codeine linctus (cough suppressant).

Solvent Abuse (misuse)

Also known as volatile-substance abuse, this is the deliberate inhalation of intoxicating fumes given o? by some volatile liquids. Glue-sni?ng was the most common type of solvent abuse, but inhalation of fuel gases such as butane, especially in the form of lighter re?lls, is now a greater problem and has become common among children – particularly teenagers. Solvents or volatile substances are applied to a piece of cloth or put into a plastic bag and inhaled, sometimes until the person loses consciousness. He or she may become acutely intoxicated; chronic abusers may suffer from ulcers and rashes over the face as well as damage to peripheral nerves. Death can occur, probably as a result of an abnormal rhythm of the heart. TOLERANCE to the volatile substances may develop over months, but acute intoxication may lead to aggressive and impulsive behaviour. Treatment of addiction is di?cult and requires professional counselling. Victims with acute symptoms require urgent medical attention. In Britain, most solvent misusers are males under 20 years of age. Around 150 deaths occur every year. (See also DEPENDENCE.)... solvent abuse (misuse)

Misuse Of Drugs Act 1971

(in the UK) an Act of Parliament restricting the use of dangerous drugs. These controlled drugs are divided into three classes: class A drugs (e.g. heroin, morphine and other potent opioid analgesics, cocaine, LSD) cause the most harm when misused; class B drugs include amphetamines, barbiturates, and cannabis, and class C drugs include most benzodiazepines and anabolic steroids. The Act specifies certain requirements for writing prescriptions for these drugs. The Misuse of Drugs (Supply to Addicts) Regulations 1997 and the Misuse of Drugs Regulations 2001 lay down who may supply controlled drugs and the rules governing their supply, prescription, etc.... misuse of drugs act 1971
