A pattern of excessive alcohol use that leads to clinically significant impairment or distress. Diagnostic criteria include a strong desire to drink alcohol, difficulties in controlling its use, risky use, e.g., driving or operating machinery while under the influence, persisting in its use despite harmful personal, social and occupational consequences, pathological organ changes, increased tolerance and physical withdrawal symptoms.

An occurrence sometimes seen in individuals recovering successfully from an alcohol or other drug use disorder who unexpectedly relapse and later trace the relapse back to a seemingly innocuous prescription issued by their physician for something unrelated such as sleep, pain, anxiety or an attention deficit disorder. Taking an addictive drug of another class may lead to a new addiction, but more than likely will lead back to the original substance of choice. Individuals with a cross addiction may also use seemingly innocent substances, such as over-the-counter sleep aids or prescription sedatives. Some even develop non-substance addictions to activities such as excessive shopping, gambling or sex.

Disorders related to recurrent use of drugs other than alcohol that cause clinically and functionally significant impairment such as health problems, disability, and failure to meet major responsibilities at work, school or home. Diagnostic criteria include intense cravings; impaired control of the amount and frequency taken; persisting in use despite harmful personal, social and occupational consequences; risky use, e.g., driving or operating machinery while under the influence; increased tolerance and physical withdrawal symptoms.
