Codependency and Addiction: Understanding the Connection
Codependency and addiction rarely exist in isolation. In clinical practice, they appear together so consistently that understanding one almost always requires understanding the other. Yet they tend to be treated separately — the person with addiction goes to treatment, while the family member or partner who has organised their entire life around that addiction goes largely unaddressed. This is a clinical oversight with significant consequences.
Where the connection comes from
The word codependency itself originated in the addiction treatment field — specifically at centres like Hazelden in the United States, which were among the first to recognise that addiction is not an individual problem but a relational one. The family system around addiction reorganises itself to accommodate the addicted person’s behaviour. Rules change. Communication becomes indirect. Certain things are never said. The family learns to function in a way that inadvertently sustains the addiction while appearing to manage it.
The person who typically carries the label of codependent is the one who is most actively trying to control or fix the situation — the partner who covers for the addicted person at work, the parent who pays the debts, the friend who always shows up in a crisis. Their behaviour looks like care and often feels like care. What it does functionally, however, is remove the consequences that might create the conditions for change.
What codependency and addiction share
Both codependency and addiction are, at their core, responses to something that has never been adequately addressed — usually early experiences of insecurity, emotional unavailability, or trauma. The person who develops addiction finds in their substance or behaviour a highly effective (if ultimately destructive) solution to emotional pain. The person who develops codependency finds in caretaking and control a way of managing anxiety, maintaining connection, and establishing a sense of worth.
Both patterns are maintained by the relief they provide. Both are resistant to change through willpower alone. And both require a kind of psychological work that goes beyond behaviour management — work that asks what these patterns have been doing, what they developed in response to, and what a different way of being in the world might look like.
Treating codependency alongside addiction
Effective addiction treatment increasingly recognises that treating the addicted person in isolation, while leaving the relational system unchanged, is rarely sufficient. The family system will tend to pull things back toward familiar patterns. The partner or parent who has been functioning codependently for years does not simply stop when the addicted person enters recovery — they often experience a crisis of identity, because caretaking has been their primary way of relating.
Individual psychotherapy for codependency runs alongside or following addiction treatment addresses this directly. It is not simply about learning to “detach with love” or set better boundaries — though those things matter. It is about understanding the deeper structure of the pattern: where it came from, what it has been protecting, and what needs to change at a psychological level rather than simply a behavioural one.
Philippe Jacquet trained at the Hazelden Foundation — one of the institutions where the concept of codependency was developed — and brings that specialism to individual work with people who are navigating the relational consequences of addiction, whether their own or someone close to them.
