What we know, what we don't, and why the gap costs lives: Reflections on building a science of recovery

There is a moment in every recovery journey, which I have witnessed hundreds of times across years of clinical practice and research, when something shifts.

Not the moment the person stops. Not when they reach out for help. Not the dramatic rock-bottom we so often romanticise in our clinical narratives. But a more subtle moment, when someone looks up, rather than down. When they begin to imagine a life defined not by what they are escaping, but by what they are moving toward.

I have seen this moment in therapy rooms, in residential settings or in peer support groups. There is something particular about this moment. Something shifts that is hard to name, harder still to measure, and yet absolutely real. Like a private reckoning of a person who finally decides that the cost is too high and the horizon might, just might, hold something worth reaching for.

And yet, as William White and John Kelly remind us with eloquent urgency in their newly published agenda for addiction recovery research, we have spent decades studying the wound. We have barely begun studying the healing.

The science we built, and the science we left behind

Our field has produced extraordinary knowledge about addiction. The neurobiology. The epidemiology. The typologies of harm. We know, with considerable precision, how substances reorganise the brain's reward architecture, how early trauma amplifies vulnerability, how poverty and isolation accelerate the trajectory toward crisis. We have catalogued, with rigorous care, the cost of addiction to individuals, families, and societies.

What we have not done, with anything like the same rigour, is study what happens when people get better. And what allows them to stay better.

White and Kelly identify twelve critical dimensions of recovery research that remain underdeveloped. They write with the careful ambition of people who have spent entire careers in this field and still see vast, uncharted territory ahead.

Reading their agenda, I found myself nodding at almost every page. Because this is precisely the territory my own research has been navigating for years, and the questions they articulate are ones I have encountered at every stage of that work.

What does recovery actually look like at five years? At ten? We don't know. Not really. We have glimpses. We have testimonies. We have early-stage prevalence data. But we do not yet have the science.

My PhD research is built on the uncomfortable observation that treatment outcomes for residential addiction programmes are poorly defined and measured inconsistently. The concept of recovery itself is rarely operationalised. Outcomes refer variably to abstinence, reduction in use, psychological symptom relief, social functioning, quality of life, often within the same study, sometimes without clear distinction. When my scoping review mapped 154 unique psychometric instruments across 88 studies published over more than three decades, what emerged was not a coherent evidence base. It was a sprawling, fragmented landscape of measurement tools that often cannot speak to one another, that rarely incorporate lived experience in their design, and that frequently mistake the absence of crisis for the presence of recovery.

White and Kelly articulate the same problem with precision. We need definitions that are not vague and aspirational, but precise, operationalised, and testable. We need measures that serve not just researchers but the people whose lives depend on the answers.

Recovery is not just subtraction

One of the passages in White and Kelly's paper that stayed with me longest is their reframing of recovery as something more than subtraction. The conventional model — reduce harm, stop the behaviour, stabilise — treats recovery as a process of removal. Take away the substance, the compulsion, the chaos. What remains is called recovery.

But anyone who has worked closely with people in long-term recovery knows this is a profound underestimation. Recovery, at its best, is generative. People do not simply return to a pre-addiction baseline. Many of them, given the right conditions and support, exceed it. They develop capacities for empathy, honesty, and community that they might never have built without the crucible of their experience. White and Kelly call this flourishing. They describe processes of addition (enhanced global health and social functioning) and even multiplication, where people become meaningfully engaged citizens in ways that ripple well beyond their own lives.

This is something I saw again and again over the years as well. The peer worker who draws on their own experience to reach someone unreachable by clinical language. The community facilitator who builds connection in spaces where shame used to live. The person three years into recovery who becomes the most insightful advocate in the room when funders gather to discuss what commissioners should prioritise. These are not just stories. They are data points in an evidence base we have not yet built.

The problem of measurement is the problem of care

There is a reason I have spent considerable research energy on psychometric tools and measurement protocols, and it is not abstract academic interest. It is because what we cannot measure, we cannot protect.

When a person leaves addiction treatment after twelve, fourteen, or more weeks of intensive immersive work, the care system needs to know more than whether they are currently abstinent. It needs to understand what they are returning to. What resources they have. What stressors are waiting. Whether the neurobiological and psychosocial gains made in the protected space of residential care will be durable in the unprotected complexity of real life.

We know, from the existing evidence, that a point of recovery stability and durability tends to emerge around four to five years of continuous recovery. We know that social connections, peer support, and recovery capital all play significant roles. We know that meaningful improvements in addiction-related indicators and psychological wellbeing are achievable, even for some of the most complex and marginalised individuals seeking treatment. But we also know that the field lacks the standardised, validated tools to track what happens next across time, across pathways, across the full arc of a person's recovery journey.

The measurement gap is not a methodological inconvenience. It is a care gap. When we cannot measure recovery consistently and validly, we cannot know which interventions work for whom, under what conditions, and at what stage of the recovery journey. We cannot make the case to commissioners for sustained investment in addiction treatment, a field that remains undervalued, underfunded, and poorly understood, because we lack the robust outcome data to demonstrate its long-term impact. We cannot design the right aftercare. We cannot identify, early enough, who is at risk of relapse.

What White and Kelly are calling for - an expanded, rigorous, longitudinal science of recovery - is, at its core, an argument for better care.

The stages we have not yet mapped

White and Kelly propose a framework of five potential stages of recovery, from pre-recovery incubation through to intergenerational cycles of resilience,  and observe that nearly everything we know from science is based on studying just one of those stages: recovery initiation. This is the stage most visible to services, most amenable to short-term measurement, and most represented in the published literature.

What comes before, and what comes long after, remains largely in shadow.

This is a challenge I encounter concretely in my own research. Residential treatment typically serves people at a specific, often late-stage moment of crisis and intervention readiness. But the recovery journey that brought them to that door, and the recovery journey that begins when they leave, is far longer, more variable, and more complex than any single episode of care can capture. The individual and environmental characteristics of sustained recovery, which my third study initiative sets out to investigate, are precisely what the field most urgently needs to understand. Who stays in recovery? What predicts durability? What distinguishes someone whose recovery deepens over time from someone who stabilises and then, years later, experiences recurrence after what White and Kelly pointedly call "decades of recovery stability"? These are not questions with easy answers. But they are questions we can no longer afford not to ask.

The How is as important as the What

White and Kelly dedicate significant attention to the ethics and methodology of recovery research, and this is where their argument becomes, for me, most challenging and most important. They call for genuine co-production, not tokenism. They warn against what they term "double agentry" (the appropriation of lived experience language to satisfy inclusion criteria, without genuine power-sharing). They argue that recovery communities are, in a meaningful sense, indigenous cultures, and that extracting knowledge from them without reciprocity is itself a form of harm.

This should make all of us, researchers, clinicians, commissioners, service designers, sit with real discomfort. Our field has not always done this well. We have consulted, then concluded. We have invited people with lived experience to advisory panels, then written the report without them. We have celebrated recovery stories at awareness events and then excluded those same voices from the rooms where funding is allocated and service models are designed.

What does recovery feel like from the inside? What domains matter most to people navigating it? What questions feel relevant, and which ones feel reductive or alien? These are things that cannot be answered from behind a desk.

It is also worth sitting with a wider discomfort here. We have mapped 154 psychometric instruments in this field. And yet most of them were designed without the people who would one day complete them having any meaningful role in shaping what was asked.

A call to build together

We are all, ultimately, working toward the same thing.

The clinician supporting someone through acute stabilisation. The residential programme manager trying to demonstrate outcomes to a sceptical commissioner. The peer support worker sitting with someone in the fragile early weeks after treatment. The researcher designing the next longitudinal study. The policy maker trying to understand what the evidence says before the next funding round opens. The family member who has lived through years of chaos and is finally beginning to believe that something more stable might be possible.

We want the same thing. Fewer people harmed. Fewer lives lost. More people reaching that quiet, defiant moment when they look up instead of down.

The science of recovery that White and Kelly call for is not the work of researchers alone. It requires providers to open their data. It requires commissioners to fund longitudinal follow-up as a matter of course, not an occasional luxury. It requires people with lived experience to be structurally embedded in research design, not consulted at the margins. It requires those of us building evaluation tools and measurement frameworks to hold ourselves to the highest standards of rigour. Precisely because the stakes are not abstract. They are the lives of people who trusted services to help them, and who deserve to know whether those services actually did.

The harm caused by addiction is enormous.

The knowledge needed to reduce it is still, in critical ways, in its infancy. We have built an impressive science of pathology.

Now we need to build, with equal commitment and equal care, a science of recovery.
