A mood disorder can be classified as substance-induced if its etiology can be traced to the direct physiologic effects of a psychoactive drug or other chemical substance, or if the development of the mood disorder occurred contemporaneously with substance intoxication or withdrawal. Also, an individual may have a mood disorder coexisting with a substance abuse disorder. Substance-induced mood disorders can have features of a manic, hypomanic, mixed, or depressive episode. Most substances can induce a variety of mood disorders. For example, stimulants such as amphetamine, methamphetamine, and cocaine can cause manic, hypomanic, mixed, and depressive episodes.
A substance-related disorder is a condition (such as intoxication, harmful use/abuse, dependence, withdrawal, and psychoses or amnesia associated with the use of the substance) associated with substance abuse, often involving maladaptive behaviors over a long period of time. In order to be diagnosed with substance dependence an individual must display at least three of the following for a 12-month period: "development of tolerance to the substance, withdrawal symptoms, persistent desire/unsuccessful attempts to stop using the substance, ingestion of larger amounts of substance, declined life functioning, and persistent use of substance." Substance abuse has been found to be most common among people 18 to 25 years of age and is also more common in males than females and in urban residents compared to those who live in rural areas. Over 50 percent of individuals with substance abuse issues have been found to have another psychiatric disorder, something that is termed Comorbid Psychiatric Diagnosis. Substance abuse is not the same in every person; it can differ in terms of the substance abused, the pattern of use and also the type of comorbid illness present, if any.
Some people can have strong drug cravings even after they have not used the drug for a long period of time. They call this being "clean". To determine how the brain triggers these cravings, multiple tests have been done on mice.
Substance-related disorders, including both substance dependence and substance abuse, can lead to large societal problems. It is found to be greatest in individuals ages 18–25, with a higher likelihood occurring in men compared to women, and urban residents compared to rural residents. On average, general medical facilities hold 20% of patients with substance-related disorders, possibly leading to psychiatric disorders later on. Over 50% of individuals with substance-related disorders will often have a "dual diagnosis," where they are diagnosed with the substance abuse, as well as a psychiatric diagnosis, the most common being major depression, personality disorder, anxiety disorders, and dysthymia.
