A drug regulated by the Federal Controlled Substance Act.
A drug which is not freely available, which is restricted by law and classified as A, B, or C and of which possession may be an offence.
In the United Kingdom, controlled drugs are those preparations referred to under the Misuse of Drugs Act 1971. The Act prohibits activities related to the manufacture, supply and possession of these drugs, and they are classified into three groups which determine the penalties for offences involving their misuse. For example, class A includes cocaine, diamorphine, morphine, LSD and pethidine. Class B includes amphetamines, barbiturates, cannabis and codeine. Class C includes drugs related to amphetamines such as diethylpropion and chlorphentermine, meprobamate and most benzodiazepines.
Controlled drugs are a category of medications that are subject to restricted usage due to their high potential for abuse. Among the controlled drugs are opiates like cocaine and morphine, amphetamine drugs, and barbiturate drugs. These substances are carefully regulated and monitored to prevent misuse and ensure patient safety. The restrictions placed on their use help to mitigate the risks associated with their addictive properties.
