Six things to do while they are in treatment.

Addiction is a family illness in a measurable way. In a large health-system study, family members of people diagnosed with alcohol or drug problems ran up hundreds of dollars a year more in medical costs than matched families, and were more often treated for depression and for substance problems of their own. One estimate puts the number of adults worldwide affected by a relative’s addiction at around 100 million. Almost none of them are handed a plan.

Help for the family works whether or not the person in treatment does well. In the best-known trial of family approaches, 130 family members of people who refused treatment were trained in one of three methods. The family members’ own wellbeing improved in all three groups, regardless of what the drinker did. Among Al-Anon attendees, long-standing members were more likely than newcomers to say they were satisfied with their quality of life, 50% against 39%. The pattern across the research is simple: the family that gets its own support is steadier, and a steadier family is a better place to come home to.

Most residential programs offer a family weekend or a few family sessions, and families often treat them as optional. The evidence says otherwise. A 2020 meta-analysis of 16 trials found that involving a significant other in treatment produced a consistent extra reduction in substance use, and the benefit was still measurable 18 months later. In one residential program that tracked 274 patients, those whose family took part in its seven-day family program completed treatment at a rate about 10% higher than those whose family stayed away.

Family sessions are also where the hard conversations get a referee. The money, the car, the phone, who gets a key: these are easier to settle with a counselor in the room than at the kitchen table on the first night.

Cravings respond to cues. In a Yale study, 93 people who had completed a month of inpatient alcohol treatment were tested for how strongly reminders of drinking provoked craving, then followed for 90 days. The stronger the cue-induced craving, the sooner they relapsed, and the effect held after adjusting for everything else measured. The half-finished bottle in the pantry, the glass they always used, the drawer, the spot in the garage: these are cues. They are cheap to remove and expensive to leave.

Do it before arrival, not with them watching. If the person wants to be part of it, do it together on the first day, as something you do with them rather than an inspection.

Behavioral couples therapy, one of the best-studied family treatments for addiction, is built around a written recovery contract: a short daily exchange in which the person states their intention to stay sober that day and the partner expresses support. In a meta-analysis of 12 randomized trials with 754 participants, adding this approach beat individual treatment on substance use and on relationship satisfaction, with the advantage on use showing up at follow-up rather than fading. The lesson travels beyond couples. Agreements that are explicit, daily and mutual hold better than rules nobody wrote down.

The questions families argue about in the first month are predictable: who holds the money, who has the car keys, whether location sharing is on, whether there is testing and who sees the result, which friends can visit. None of them get easier once the person is home. Settle them in the last two weeks of treatment, with a counselor in the room, and put a date on each one for revisiting it.

How the household talks turns out to be one of the better predictors of relapse. In a study of 86 people in alcohol treatment, those whose spouses scored high on criticism and hostility, what researchers call expressed emotion, were more likely to relapse over the following year than those whose spouses scored low. The point is not to walk on eggshells. It is that interrogation, sarcasm and the nightly “are you sure you should” carry a measurable cost.

CRAFT, the family approach with the best engagement record, is in large part a communication course: brief, positive, specific, and about the behavior rather than the person. In the head-to-head trial, family members trained this way got a reluctant drinker into treatment 64% of the time, against 30% for a traditional confrontational intervention and 13% for Al-Anon facilitation. How the family talks changes what happens next.

The month after discharge is the riskiest one, as Issue 01 covered. The plan for it should exist before the drive home: the first appointment date, the meetings, who drives, what the first Saturday looks like. And it should include the outcome nobody wants to talk about. In two randomized trials of scheduled check-ups after treatment, people who got the check-ups returned to treatment when they needed it more often (55% against 37% in the second trial) and about a year sooner.

A slip with a plan behind it is a bad week. A slip without one can become a bad year. Decide now how you will know, who makes the first call, and what does not happen that night: no ultimatums, no big decisions, no new rules until the call has been made.
