When a family first calls Holina, the question of duration usually arrives within the first ten minutes of the conversation. Sometimes it is asked openly. More often it is implied — through a question about cost, about time off work, about whether a 28-day program is what is on offer because that is the figure they have heard. Behind the practical question sits a quieter one: how long does this actually take.

It is a fair question, and it deserves a fair answer. The honest version is that recovery takes longer than a residential admission of any length. But within a residential setting, the length of stay meaningfully affects the depth of work that can be done, the stability of the nervous system at discharge, and the probability of relapse in the months that follow. Choosing between 30, 60, and 90 days is not arbitrary. The right answer is determined by clinical history, not by what is most convenient.

This piece is for families trying to make that decision well.

What Each Length Is Actually Designed To Do

The length-of-stay evidence is unambiguous. The National Institute on Drug Abuse states that “research has shown that most addicted individuals need at least three months in treatment to significantly reduce or stop their drug use, and the best outcomes occur with longer durations of treatment.”

A 28-to-30-day admission is, in clinical terms, the minimum residential window in which a complete arc of stabilisation, initial trauma work, and discharge planning can be accomplished. It is appropriate for clients whose dependence is moderate, who have a supportive home environment to return to, who do not have significant co-occurring conditions, and who have not previously cycled through residential care. For these clients, 30 days can be sufficient — particularly when followed by structured aftercare.

A 60-day admission expands the middle phase of treatment. It is, in our experience at Holina, the most useful length for the majority of clients we see. The first 30 days are largely about stabilisation: clearing withdrawal, regulating sleep, restoring nutritional baseline, and establishing the relational safety in which deeper work becomes possible. The second 30 days are where that deeper work — somatic processing, attachment-focused therapy, the slow examination of the patterns that produced the addiction — actually happens. Cutting treatment at 30 days frequently means cutting it at the moment it was starting to land.

A 90-day admission is the standard recommendation for severe alcohol dependence with multiple prior treatment episodes, opioid dependence with significant medical complications, stimulant use with documented neurological impact, or any presentation involving complex trauma and dual diagnosis. The third 30 days are where new patterns become embodied rather than merely understood, where the returning person consolidates the work into a felt sense of safety rather than an intellectual map. Ninety days is not the longest a serious addiction may benefit from. For some clients, six months is the more honest figure. But ninety days is the window beyond which the data on retention, relapse, and long-term outcome shifts meaningfully in the client’s favour.

What the Clinical History Actually Predicts

The variables that matter most, in roughly decreasing order of weight:

How long the active use has continued. A pattern that has run for less than 18 months responds differently to a residential window than one that has run for ten years. Longer histories require longer admissions, almost without exception.

Whether the client has been in residential treatment before. A first admission can sometimes succeed at 30 days. A third or fourth admission almost never does. The clinical question is no longer whether the person will achieve initial sobriety — they have, before — but whether they will sustain it, and sustaining requires the longer windows in which the underlying drivers can be addressed.

What is being used, and at what dose. Alcohol dependence at a half-bottle of spirits a day is a different admission from alcohol dependence at three bottles a day. Opioid dependence requires longer detox stabilisation than alcohol or stimulant dependence. Polysubstance use — alcohol with cocaine, or benzodiazepines with opioids — requires longer windows on the medical side before the psychological work can begin in earnest.

What else is present. Untreated trauma, undiagnosed ADHD, depressive disorders, anxiety disorders, eating-related patterns, and behavioural addictions such as gambling or compulsive sexual behaviour all extend the appropriate length of admission. Treating only the substance, when other conditions are also operating, is the most common reason short admissions fail.

What the home environment looks like. A returning person walking into a stable, recovery-aware household needs less residential time than one returning to active substance use in the home, an unstable relationship, or significant ongoing financial or legal stress.

The Mistake Families Make Most Often

It is, almost invariably, the same mistake. The family chooses the shorter admission because the cost is lower and the time away is more manageable. The client completes the admission, returns home, does well for two or three months, and then relapses around month four. The family then funds a second admission, often longer, and the total cost in money, time, and emotional bandwidth is significantly higher than if they had simply chosen the appropriate length the first time.

This is not a moral failure on the family’s part. It is a structural feature of how residential treatment is sold and how families instinctively budget for crisis. But it is, in our experience, the single most expensive misjudgement a family can make. A 60-day admission, well-chosen and well-followed-up, frequently saves the cost of the second 30-day admission that would otherwise have been required.

We are not, when we say this, advocating for longer admissions as a default. We are advocating for the clinically appropriate admission, which is sometimes 30 days and sometimes 90 and very rarely the figure a family first arrived with.

How To Have the Conversation Internally

The most useful family conversations about length share a structure. They begin with a clear-eyed account of the history — how long, how much, how often, what else is going on — rather than with a budget. They consult the admitting team about what would be appropriate from a clinical standpoint before deciding what is feasible from a financial one. They make space for the possibility that the right answer is not the cheapest one, and they think about cost in the longer frame of likely outcomes rather than the shorter frame of the line item on this month’s calendar.

Where the financially feasible length is shorter than the clinically appropriate length, the conversation does not end. It moves to aftercare. A 30-day admission with a six-month structured aftercare plan can, for some clients, approximate the outcome of a 60-day admission alone. It is not equivalent, but it is meaningfully closer than 30 days alone.

What Aftercare Adds, and Why It Matters More Than Most Families Expect

The single most underweighted variable in residential treatment outcomes is what happens in the six months after discharge. A 60-day admission followed by nothing has a worse one-year outcome than a 30-day admission followed by structured aftercare. The treatment, in other words, does not end at the gate.

Holina’s aftercare model is intentionally lighter in intensity and longer in duration than the residential program itself — regular clinician contact, structured re-engagement at defined intervals, family check-ins, and where appropriate, returning periods on the campus for short consolidation stays. Families who fund the residential admission only, and treat aftercare as optional, are funding the easier half of the work. Aftercare is where the harder half happens.

A Closing Note on the Number

There is no length of admission that guarantees an outcome. There is no length so short it cannot be a useful start, and no length so long it does the work for you. What length does is determine how much of the work can happen inside the protected setting, and how much of the work has to be carried by the person and their family in the months that follow.

For most clients reaching Holina, sixty days is the figure that produces the right balance — long enough to do the work that matters, short enough to remain financially and logistically realistic for most households. For some, thirty days plus a serious aftercare commitment is the right shape. For others, ninety is the only honest answer.

The conversation, when you are ready to have it, can start with the admissions team. We will not sell you a longer admission than you need. We will, however, tell you honestly what we think the appropriate length is, given the history, and we will leave the decision in your hands once you have that information.
