What Is an Addiction Psychiatrist?
An Addiction Psychiatrist is a medical consultant who specialises in the diagnosis and pharmacological treatment of substance use disorders and behavioural addictions, often occurring alongside other mental health conditions (Dual Diagnosis).
In the medico-legal arena, these experts are essential for evaluating the relationship between addiction and legal issues. They assess whether a dependency is a primary condition or a symptom of underlying trauma, and provide objective evidence on treatment prospects. Common areas of focus include:

Frequently Asked Questions
In family court, an addiction psychiatrist assesses how a parent’s substance misuse affects their parenting capacity and the risk posed to children. They provide a clinical diagnosis of dependency, evaluate the parent’s level of insight, and recommend treatment pathways (such as detox or rehab) to determine if the parent can safely care for the child within the child’s timescale.
Yes. Dual diagnosis (the co-occurrence of a mental health disorder and a substance use disorder) is a core area of expertise. The psychiatrist evaluates which condition is primary, how they interact (e.g., self-medicating for PTSD), and provides a comprehensive integrated treatment plan for both conditions.
The psychiatrist reviews laboratory results from hair, blood, or urine tests to corroborate the individual’s self-reported substance use. They use this data to identify patterns of use, verify periods of abstinence, and assess the clinical significance of the findings in relation to the legal issues at hand.
Yes. Many of our addiction psychiatrists are trained to assess non-substance related addictions such as gambling or gaming disorders. These are often relevant in financial capacity cases, employment disputes involving theft, or family proceedings where household finances have been severely impacted.
An addiction psychiatrist is a medical doctor who can assess the physical health consequences of addiction, prescribe medication for detox/maintenance, and diagnose complex medical-psychiatric comorbidities. An addiction psychologist focuses on behavioural patterns, cognitive therapy, and psychometric testing. Both are often instructed together for a holistic view.
Yes. This is a critical assessment in criminal cases. The psychiatrist determines if a psychotic episode was temporary and directly caused by substance use (e.g., cannabis or cocaine) or if it indicates an underlying primary psychotic disorder like schizophrenia, which has significant implications for criminal responsibility and sentencing.
