Controlled Substance

Category: Legal · Level: Beginner

A controlled substance is a drug or chemical whose manufacture, possession, and use are regulated by law due to potential for abuse or harm.

A controlled substance is any drug or compound regulated by government under a legal framework that controls its manufacture, possession, distribution, and use. In the United States, the Controlled Substances Act (CSA) of 1970 classifies substances into five schedules based on medical use, abuse potential, and safety profile. Cannabis remains Schedule I federally. In the UK, controlled drugs are classified as Class A, B, or C under the Misuse of Drugs Act 1971; cannabis is Class B. The UN Single Convention on Narcotic Drugs (1961) and Convention on Psychotropic Substances (1971) provide the international framework for controlled substance regulation globally.
