A controlled substance refers to a drug or chemical substance whose distribution, possession, and use are regulated by government authorities. These substances have the potential for abuse and can lead to physical or psychological dependence. The control over their production, distribution, and consumption is enacted to protect public health and to prevent illicit activities associated with their misuse.
Controlled substances are categorized into different schedules that determine the level of regulation and the severity of penalties for their unauthorized production, distribution, and possession. The schedules are arranged based on the substance's potential for abuse, accepted medical use, and safety levels.
These substances can include various drugs, both legal and illegal, such as narcotics, stimulants, depressants, hallucinogens, and certain prescription medications. Examples of controlled substances include heroin, cocaine, marijuana, methamphetamine, morphine, codeine, oxycodone, and amphetamines, among others.
The regulation of controlled substances involves licensing professionals and facilities involved in their production, distribution, and prescription, as well as monitoring their movement to prevent diversion and ensure proper use. The aims of controlling these substances are to minimize harm, reduce drug-related crime, promote public safety, and maintain the integrity of the healthcare system.
The word "controlled substance" has a straightforward etymology. It is a compound of two nouns: "controlled" and "substance".
The term "controlled" derives from the verb "control", which entered Middle English from Old French in the 14th century. It originated from the Latin word "con-" meaning "together" and "trollere" meaning "to move or roll". Thus, "control" originally referred to the act of moving or rolling together, and over time, it developed the meaning of managing or regulating something.
The word "substance" has an even older origin. It comes from the Latin noun "substantia", which is a combination of "sub-" meaning "under" and "stantia" meaning "standing". Hence, "substance" refers to something that stands under or as the foundation of something, a fundamental or essential matter.
