Substance-related disorder
Substance-related disorder (pronunciation: /ˈsʌbstəns rɪˈleɪtɪd dɪsˈɔːdər/) is a term used to describe a range of conditions that involve an unhealthy use of psychoactive substances, which lead to clinically significant impairment or distress.
Etymology
The term "substance-related disorder" is derived from the English words "substance", "related", and "disorder". "Substance" comes from the Latin word "substantia", meaning "essence, material". "Related" is derived from the Old English word "rǣdan", meaning "to advise, interpret". "Disorder" comes from the Latin word "disordinare", meaning "to throw into disorder".
Definition
Substance-related disorders encompass 10 separate classes of drugs: alcohol; caffeine; cannabis; hallucinogens (with further subcategories for phencyclidine or similarly acting arylcyclohexylamines, and other hallucinogens); inhalants; opioids; sedatives, hypnotics, or anxiolytics; stimulants (amphetamine-type substances, cocaine, and other stimulants); tobacco; and other or unknown substances. These disorders can be categorized into two types: substance use disorders and substance-induced disorders.
Substance Use Disorders
Substance use disorders are characterized by the harmful consequences of repeated use, even if the individual is not currently using the substance. These disorders can cause significant impairment and distress in the individual's life. They are further categorized into substance dependence and substance abuse.
Substance-Induced Disorders
Substance-induced disorders, including intoxication, withdrawal, and other substance/medication-induced mental disorders, are detailed in the diagnostic criteria for each substance.
