Controlled substance

A controlled substance is generally a drug or chemical whose manufacture, possession, or use is regulated by a government, such as illicitly used drugs or prescription medications that are designated a Controlled Drug. Some states in the U.S. have statutes against health care providers self-prescribing and/or administering substances listed in the Controlled Substance Act schedules. This does not forbid licensed providers from self-prescribing medications not on the schedules.
