Disorders due to substance use
Definition
Disorders due to substance use include disorders that result from a single occasion or repeated use of substances that have psychoactive properties, including certain medications. Disorders related to fourteen classes or groups of psychoactive substances are included. Typically, initial use of these substances produces pleasant or appealing psychoactive effects that are rewarding and reinforcing with repeated use. With continued use, many of the included substances have the capacity to produce dependence. They also have the potential to cause numerous forms of harm, both to mental and physical health. Disorders due to harmful non-medical use of non-psychoactive substances are also included in this grouping.
