Relapse is not failure. It is information.

Relapse in treated substance dependence runs at roughly 40 to 60 percent, the range McLellan and colleagues reported in JAMA in 2000, and the same range at which type 2 diabetes, hypertension and asthma recur when patients drift from their treatment plans. In a 2019 national study by Kelly and colleagues, people who had resolved a serious alcohol or drug problem had made an average of 5.35 recovery attempts, with a median of 2. A relapse is therefore an expected event in a chronic condition, and the week that follows it is the most clinically useful week a family will get. This article sets out the relapse autopsy, the detection of concealed use, the 24-hour disclosure rule, and the readmission criteria.

The relapse autopsy

The relapse is reconstructed on paper as a dated sequence, working backwards from the first use. Five dates are established, in this order: when sleep changed, meaning the waking time drifted or the afternoons emptied of structure; when meetings or counselling stopped, taken as the date of the last session actually attended, not the person's estimate; when the first lie was told, usually about attendance or whereabouts; when cash appeared, meaning unexplained withdrawals, borrowed money or missing items; and when old contacts resumed, the former drinking group or the dealer's number that was never deleted.

The first drink or first use is almost always the last entry on that timeline, weeks after the first. Each entry is a correction point, and one carries direct trial evidence: a 2020 Cochrane review of 27 studies and 10,565 participants found manualised twelve-step facilitation produced higher continuous abstinence at twelve months than other active treatments, 42 percent versus 35 percent. A stopped meeting schedule therefore means a protective factor with that weight of evidence was switched off weeks before the substance appeared.

A worked example. A man eight months abstinent drinks on a Saturday. The written autopsy establishes: waking time drifted from 06:00 to 09:00 when a contract ended in month six; the last meeting attended was five weeks before the drink; the first lie, a claimed Tuesday meeting, came four weeks before; cash withdrawals without receipts began two weeks before; contact with a former drinking partner resumed ten days before. The plan correction is written against each entry: mornings structured around work-seeking, meeting attendance verified rather than reported, finances visible to a second person. A general resolution to do better corrects none of the five entries.

Detecting the concealed relapse

A concealed relapse presents later and clinically worse than a disclosed one, because concealment re-establishes the double life. The signs are behavioural: clothes washed at unusual times, deleted messages, an invented work trip, borrowed money, renewed defensiveness over small questions, and aftercare sessions missed in an escalating pattern, one and then three. Added shame from the family predictably increases concealment rather than disclosure, so questioning after a suspected use follows a medical history format: what exactly was used or drunk, how much, over what period, where the money came from, who else knows, and whether anything remains in the house or the car.

The 24-hour disclosure rule

The rule is agreed before any relapse occurs, in writing where possible: a use is disclosed within 24 hours to a named circle, the counsellor, the sponsor where there is one, the treating doctor if medication is involved, and the centre. The family's obligation is fixed in the same agreement: disclosure inside the window is met with logistics, not argument. A lecture delivered at first disclosure trains the person to hide the next one.

Safety runs ahead of the rule. Alcohol and benzodiazepine withdrawal can be medically dangerous, including seizures, and the risk is highest with heavy daily use, previous complicated withdrawal or concurrent illness; nobody in those categories stops suddenly at home. Where detoxification is needed it is arranged medically, off-site, before readmission. Within the first 48 hours, immediate access is removed as temporary containment: cash, cards, car keys, alcohol in the house, known contacts.

Readmission criteria

Any one of the following indicates readmission rather than home management: the person cannot give an honest account of the extent of use; there is withdrawal risk as defined above; the relapse was discovered rather than disclosed; or the home environment supplied it, meaning the substance or the contacts sit inside the household. Where the use was single, disclosed inside the window, medically safe, and the aftercare structure can be restarted within days, outpatient management with tightened structure and testing is defensible.

The response is the predictor

The event carries less prognostic weight than the week that follows it. The pattern across thirty years is consistent: the people who stabilise disclose early, accept added structure without negotiating, and return to routine within days; the people who do badly disappear, change numbers, and assign the relapse to the centre or the family. The autopsy, the disclosure rule and the readmission criteria are how the next attempt is informed by the last.
