Clinical overview
Quick answer
A good addiction assessment examines what is used, how, why, and with what consequences, alongside withdrawal risk, physical health, mental health, medication, safeguarding, and personal goals.
What this means
Diagnosis is only one part of assessment. Immediate safety, severity, treatment preferences, social needs, and readiness for change determine the care plan.
Key distinctions
- Screening tools do not replace a clinical interview
- collateral information requires consent and care
- reassessment is normal as stability improves.
Signs and patterns clinicians assess
A clinician looks at the pattern over time, its severity, the person’s baseline, and the consequences—not at one isolated behaviour. Relevant features can include:
- loss of control over use or behaviour
- continued use despite physical, psychological, social, legal, or occupational harm
- craving, preoccupation, or repeated unsuccessful efforts to cut down
- reduced participation in valued relationships, work, education, or activities
- tolerance or withdrawal when these are relevant to the substance
These signs are not a self-diagnosis. Intoxication, withdrawal, prescribed use, pain, sleep disorders, and mental-health conditions can overlap, so assessment should establish what is happening and what is immediately unsafe.
Health and safety risks
Risk depends on the substance or medicine, route, dose, frequency, combinations, physical health, mental health, and environment. Important concerns include:
- injury, overdose, poisoning, or dangerous interactions
- worsening physical and mental health
- relationship, financial, housing, educational, or employment disruption
- shame and stigma that delay assessment
- higher risk during relapse after a period of abstinence because tolerance may have changed
Assessment and treatment
Good care starts with consent, dignity, and a clear assessment of immediate risk. Treatment intensity should be matched to clinical need rather than to marketing labels or a fixed programme length.
- a confidential, person-centred assessment of substance use, health, mental health, safety, and goals
- evidence-based psychological treatment matched to the person and substance
- medication when it is indicated for withdrawal management or ongoing treatment
- family or social support with the person’s consent
- continuing care, recovery planning, and rapid re-entry to treatment after setbacks
Recovery plans should state who is responsible for medication, crisis support, physical-health follow-up, family communication, and continuing care. A lapse should trigger prompt reassessment and additional support—not abandonment or shame.
When to seek urgent help
Call local emergency services for unconsciousness, breathing difficulty, seizure, severe confusion, chest pain, suspected overdose, immediate suicide risk, or rapidly worsening agitation. Do not leave the person alone while help is being arranged.
Questions to ask a treatment provider
- Who performs the medical and psychiatric assessment, and what are their current qualifications and registrations?
- How is withdrawal, overdose, suicide risk, medication, and physical illness managed?
- Which treatments are offered for this specific condition, and what evidence supports them?
- What happens if symptoms worsen or hospital care is required?
- How are outcomes, complaints, safeguarding, discharge, and continuing care handled?
Frequently asked questions
Can this condition be treated?
Yes. Treatment should be matched to the substance or behaviour, severity, withdrawal and overdose risk, physical and mental health, previous response, goals, and available support. More than one episode of care may be needed.
Does withdrawal mean someone has an addiction?
Not necessarily. Withdrawal can indicate physical dependence, including during appropriate prescribed treatment. Addiction additionally involves impaired control, prioritisation, and continued use despite harm. A clinician can distinguish these patterns.
What is the safest first step?
Arrange a confidential assessment with a qualified addiction or medical service. Use emergency services immediately for overdose, seizure, breathing difficulty, severe confusion, dangerous psychosis, or immediate suicide risk.
