A practical guide
Understanding Substance Use
Substance use exists on a spectrum and can affect physical health, mood, relationships, work, and safety. People may use substances for many reasons, and support should be respectful and free from shame. Mental health and substance-related concerns can occur together and may both need attention.
What this topic can include
- What a substance does for you in the short term and what effects you notice later.
- How mental health, stress, trauma, physical health, and social context may connect with use.
- Treatment, harm-reduction, peer, and recovery supports available in your area.
Optional reflection
Notice the pattern without judgment
- 1If it feels safe, note the situation, feeling, or need that came before use.
- 2Notice what changed afterward, including any unwanted effects.
- 3Write down one person or service you could contact to discuss options.
Do not stop or change regular substance use or medication suddenly without medical advice; some withdrawals can be dangerous.
