Recognizing physical dependence
Safety & Harm Reduction — Guide 17 of 25

Physical dependence means the body has adapted to a substance. Reducing or stopping it may cause withdrawal. This can happen with prescribed medicine too.

Possible clues
- Feeling unwell when a dose is late or use decreases.
- Taking a substance to relieve withdrawal symptoms.
- Needing more to get an effect that used to occur with less.

Physical dependence does not establish a substance use disorder
Physical dependence alone does not establish a substance use disorder. A substance use disorder involves a broader pattern of problems, such as impaired control and continued use despite harm. A clinician can help work out what is happening.

Make changes with support
Do not change prescribed medicines without speaking to the prescriber. If you think you are dependent on alcohol or sedating medicines, seek medical advice before stopping suddenly. Write down what you use, how often, and what happens when you miss it. Bring that information to an appointment.

If you are helping someone
Encourage medical advice; do not tell someone who may be dependent to stop suddenly.

WARN (OTHERS): After immediate care is covered, share dated advisories or observed concerns. Say what is confirmed and what is uncertain. Protect people’s privacy. Emergency care comes first. Never share someone’s name, identifying photo or private health details.

Your next step
Ask a clinician: “Could these symptoms be withdrawal, and how can I make a safe change?”
