What is a Substance Use Disorder?

Substance use disorders are often referred to as addictions. Misuse of substances such as drugs and alcohol can cause significant problems or distress. It can also lead to legal problems. A substance use disorder will often interfere with relationships and work responsibilities.

Substances that are frequently misused or used illegally include:

  • Alcohol
  • Marijuana
  • Prescription pills, such as pain pills, or anxiety pills
  • Methamphetamine
  • Opioids
  • Cocaine

When a person begins to misuse a substance, such as alcohol, they may not initially be impacted by negative effects. However, over time the harmful consequences of addiction may develop.

When to See a Doctor

If you or a loved one is showing signs of a substance use disorder, then you should consult with a physician as soon as possible.

Causes

A substance use disorder can be caused by multiple factors including the following:

  • Genetics
  • Environmental stressors
  • Social pressures
  • Mental health problems

Diagnosis and Tests

A physician or qualified mental health professional will diagnose a substance use disorder. He or she will ask about the frequency of use, and the length of time since the substance was last used.

Treatments

A person with a substance use disorder will often have times of remission (when it seems to be under control) and relapse (when the addiction begins again). If untreated, it can lead to death.

There are several options for treatment for those with a substance use disorder. What’s best for you depends on your circumstances. You can work with your doctor to decide which solution works best for you.

Your treatment might combine two or more of the following:

  • An addiction treatment program
  • Counseling with an addiction specialist
  • Withdrawal medication
  • Support groups
