Know the Signs

Recognizing when someone is struggling with substance use can be difficult. Changes in behavior often happen gradually, and they can look different for everyone. Learning what to look for is the first step in offering compassionate support.


Understanding Substance Use Disorder

Substance Use Disorder (SUD) is a complex, treatable medical condition, not a moral failing or a lack of willpower. It affects a person's brain and behavior, leading to an inability to control the use of a legal or illegal drug or medication.

Often, SUD does not exist in a vacuum. According to the Substance Abuse and Mental Health Services Administration (SAMHSA), many individuals experience co-occurring disorders meaning they have both a substance use disorder and a mental health condition (such as anxiety, depression, or trauma) at the same time. Treating both simultaneously is the standard for effective recovery.

What to Look For

Behavioral Shifts

  • Pulling away from family, friends, or hobbies they used to enjoy.
  • Unexplained absences from work, school, or important obligations.
  • Engaging in secretive behaviors or lying about their whereabouts.
  • Experiencing sudden legal, financial, or relationship problems.

Physical & Health Changes

  • Noticeable changes in sleeping or eating habits (insomnia or extreme lethargy).
  • Unexplained weight loss or gain.
  • Changes in personal grooming, hygiene, or physical appearance.
  • Bloodshot eyes, unusual smells, or poor physical coordination.

Emotional & Psychological Signs

  • Sudden or extreme mood swings, irritability, or angry outbursts.
  • Periods of unusual hyperactivity, agitation, or giddiness.
  • Unexplained paranoia, anxiety, or lack of motivation.
  • Exhibiting signs of depression, hopelessness, or expressing suicidal thoughts.

Not a Diagnosis

These signs are indicators, not a formal medical diagnosis. If you or someone you know is exhibiting these behaviors, professional guidance can help.
