Conditions & symptoms

Substance Use Disorders

Substance use disorders involve patterns of alcohol or drug use that become difficult to control and begin causing harm, risk, or functional impairment.

Common signs & symptoms

Possible signs include escalating use, craving, loss of control, tolerance, withdrawal, continued use despite harm, secrecy, impaired responsibilities, risky behavior, or repeated unsuccessful attempts to cut down.

How it can affect daily life

Substance use may affect physical health, mood, sleep, relationships, finances, employment, legal risk, and safety. It may also coexist with trauma, depression, anxiety, or other mental-health conditions.

When to seek help

Professional assessment is appropriate when substance use is causing harm, feels difficult to control, creates withdrawal risk, or is being used to manage emotional pain or trauma symptoms.
