Understanding Substance Use Disorder

Recognize the signs and get help.

How Do I Recognize Unhealthy Substance Use?

It can be hard to recognize signs of substance use. After all, you might not think twice about some of the subtle signs that appear to be innocent. Pay attention to your intuition. If you notice some of the signs below, you may be dealing with a loved one who has an unhealthy relationship with substances. Or, perhaps you recognize some of these habits in your own life. Some possible signs include:3

  • Problems at school or work. Frequent absences, a sudden disinterest in school activities or work, or a drop in performance.
  • Physical health issues. Lack of energy and motivation, weight loss or gain, or red eyes.
  • Neglected appearance or overall health. Lack of interest in clothing, grooming or looks, as well as physical wellbeing.
  • Changes in behavior. Drastic changes in behavior or in relationships with family and friends. Things like exaggerated efforts to keep family members out of their room and being secretive about where they go with friends.
  • Money issues. Sudden requests for money without a reasonable explanation, discovering that money may be missing or stolen, or that items may have disappeared from your home that may be sold to support drug use.
  • Substance use patterns. Using more of a substance to get the same effect, using substances more frequently than before, exhibiting  physical symptoms of withdrawal (e.g. excessive hunger, noticeable fatigue, dilated pupils, anxiety), when unable to use a substance or spending more time trying to get the substance.
