Substance use disorder

Substance use disorder (SUD), also known as drug use disorder, is a condition in which the use of one or more substances leads to a clinically significant impairment or distress. Substance use disorders are characterized by an array of mental, physical, and behavioral symptoms that can cause problems related to impaired health, impaired social function, and voluntary control over substance use.

Signs and Symptoms

The symptoms of substance use disorders can vary widely depending on the type of substance being used, the duration of use, the frequency of use, and the individual's overall health status. Common symptoms include:

• Continued use of the substance despite negative consequences
• Difficulty controlling or reducing use of the substance
• Spending a significant amount of time obtaining, using, or recovering from the effects of the substance
• Cravings or strong desire to use the substance
• Failure to fulfill major role obligations at work, school, or home due to substance use
• Continued use of the substance despite persistent or recurrent social or interpersonal problems caused or exacerbated by the effects of the substance

Causes

Substance use disorders can be caused by a variety of factors, including genetic predisposition, environmental influences, and the pharmacological effects of the substance itself.

Treatment

Treatment for substance use disorders typically involves a combination of medication, counseling, and support groups. The specific treatment plan will depend on the individual's needs and the type of substance being used.
