Recognise it early
Risk & warning signs
Not everyone with ADHD will develop a substance use disorder — but several factors raise the odds, and the early signs are recognisable.
Factors that raise risk
Untreated or undiagnosed ADHD
The single largest modifiable risk factor. Diagnosis and treatment lower long-term risk.
Family history of ADHD or addiction
Genetics account for a substantial share of risk in both conditions.
Co-occurring conditions
Depression, anxiety, conduct disorder, and trauma each amplify substance-use risk.
Early substance exposure
First use before age 15 is associated with much higher dependence risk later.
Unstable environment
Chronic stress, low support, and unstructured routines compound ADHD vulnerabilities.

When to seek help
If substance use is affecting your health, relationships, work, or ability to do things you care about — that is enough reason to talk to a professional. You do not have to wait for “rock bottom.”
Start with your GP, primary-care doctor, or a qualified mental health clinician. Ask specifically about an ADHD assessment if you’ve never had one; the two conditions are best treated together.
