What to watch for

Notice changes, then start a conversation.

Substance misuse can be difficult to recognize, especially when someone is working hard to hide it. Look for clusters of changes over time rather than relying on a single sign.

A supportive group conversation

Possible behavioral changes

Concern may be warranted when several changes appear together or intensify.

  • Sudden secrecy, isolation, or new social circles
  • Missed work, school, family, or financial responsibilities
  • Unexplained money problems or missing valuables
  • Risky driving, legal trouble, or repeated accidents
  • Loss of interest in activities that once mattered

Possible physical or emotional changes

Different substances can affect people differently, and many symptoms can have other medical causes. A qualified healthcare professional should make the assessment.

  • Major changes in sleep, appetite, energy, or appearance
  • Unusual agitation, anxiety, depression, or mood swings
  • Slurred speech, poor coordination, tremors, or confusion
  • Signs of withdrawal when use stops
  • Increasing tolerance or needing more for the same effect

What to do next

Choose a safe, calm time to share what you have observed. Offer a specific next step — a call to a professional, a treatment assessment, or an RU meeting — and set appropriate boundaries. Do not attempt to manage severe withdrawal at home without medical advice.
