There are several different classes of psychoactive substances: antidepressants are used for the relief of symptoms of major depression. lithium is the most common agent used to treat manic episodes of bipolar disorder. antipsychotic agents (or major tranquilizers) are used for management of the manifestations of psychotic disorders such as schizophrenia. antianxiety agents (called also minor tranquilizers), such as diazepam (Valium), are used for relief of anxiety disorders. While none of these drugs can effect a cure, they can reduce the severity of symptoms and permit the patient to resume more normal activity.

Also included in the category of psychotropic drugs are many other substances that affect the mind but are not used to treat mental disorders, including stimulants such as caffeine, amphetamines, and cocaine; opiates; and hallucinogens.
substance-related disorders any of the mental disorders associated with excessive use of or exposure to psychoactive substances, including drugs of abuse, medications, and toxins. The group is divided into substance use disorders and substance-induced disorders, each of which is specified on the basis of etiology, such as alcohol use disorders. See also drug abuse and drug dependence.
