The following is an excerpt from the 6-CE SWTP CEUs course, Substance Use in Families: Beyond the Identified Patient.

The intake form says Miguel Torres, age 16, marijuana use. His school social worker made the referral after the third time he showed up high to class. You’re three minutes into the family session when you realize Miguel’s not the only person in the room who’s using.

Rosa, Miguel’s mother, mentions she has wine with dinner “to take the edge off” after work at the hospital. Then she corrects herself—wine with dinner and maybe another glass while she’s making dinner. And okay, sometimes a glass while she’s helping Miguel’s little sister Sofia with homework because twelve-year-olds doing pre-algebra can really test your patience. She laughs when she says this. Miguel rolls his eyes. Carlos, the father, looks at his phone.

You’ve got a choice to make, and you’re making it in real time. Do you stay focused on Miguel’s marijuana use—which is, after all, why everyone’s here—or do you widen the lens?

Most of us were trained to treat the identified patient. The person whose name is on the intake form, whose behavior triggered the referral, whose substance use is the “presenting problem.” We assess that person, develop a treatment plan for that person, and measure success by whether that person stops using or uses less. The rest of the family shows up for collateral information, maybe for a psychoeducation session about addiction, perhaps for a family session or two if we’re being thorough.

But here’s what you already know from your caseload: substance use doesn’t happen in a vacuum. Miguel didn’t start smoking weed because of a chemical imbalance in his brain or because of peer pressure alone. He started smoking in a context—a family system where mom numbs her stress with wine, where dad checks out emotionally, where Sofia has learned to stay quiet and not make waves. The family patterns that existed before Miguel’s marijuana use have shaped his relationship with substances, and his marijuana use has now become part of the family’s way of functioning.

When families come to you with an identified patient, they’re bringing you their working theory of the problem: “Fix Miguel, and everything will be fine.” Your job isn’t to accept that theory uncritically. Your job is to understand the whole system that’s maintaining the problem and to help the family see what they can’t see from inside it.

Research consistently shows that family involvement in substance use treatment improves outcomes across multiple measures. Meta-analyses of family-based interventions demonstrate that people who receive treatment with family participation stay in treatment 50-60% longer than those in individual treatment alone. They’re significantly more likely to achieve initial abstinence or substantial reduction in use, and critically, they maintain those changes at higher rates during follow-up periods extending 12-18 months post-treatment. The effect sizes are particularly strong for adolescent substance use and for alcohol use disorders in adults, though benefits appear across substance types and age groups.

But it’s not just about outcomes. It’s about understanding the problem correctly in the first place. Miguel’s marijuana use is both a symptom of family distress and a contributing factor to it. You can’t untangle one without addressing the other. When you treat Miguel individually while ignoring that Rosa drinks to cope with the stress of managing Miguel’s behavior, you’re missing that they’re caught in a feedback loop where each person’s substance use reinforces the other’s.

This matters across every setting where you practice. If you’re a school social worker, you’re seeing kids like Miguel whose substance use is intertwined with family patterns that show up in academic struggles and behavior problems. The same family dynamics that maintain substance use—parental inconsistency, emotional unavailability, crisis-driven connection—also undermine the structure and support students need to succeed academically. If you’re working in child welfare, you’re making safety assessments where parental substance use is only part of the picture—you need to understand the family system’s protective capacities and risk factors. Does the parent using substances have a partner who can provide supervision and care? Are extended family members available and safe? How do the family’s communication patterns affect whether children disclose problems or hide them?

Hospital social workers discharge patients back into family systems that will either support recovery or undermine it. You can connect someone with the best outpatient treatment program, but if they’re returning to a spouse who undermines their sobriety or to a household where substance use is normalized, relapse risk increases dramatically. Understanding family patterns helps you anticipate barriers and strengthen discharge planning. Outpatient therapists who focus only on the individual miss the family patterns that will sabotage treatment. You teach someone coping skills in session, but when they go home to a family organized around crisis, those skills get overwhelmed by the system’s pull back toward familiar patterns.

You don’t need to be a family therapy specialist to think systemically. You need to be curious about context, willing to ask questions about family patterns, and ready to see substance use as a family issue even when only one person is using. The assessment questions you already ask—”Who lives in your home? How does your family respond when you use substances? What’s your family history with substance use?”—these are systems questions. You’re already gathering information about context. The shift is in how you use that information to inform treatment planning.

The Torres family will show up throughout this course because their story illustrates what you see every day: substance use in families is never just about one person. When you start paying attention to the whole system, treatment planning changes. Goals change. Interventions change. Sometimes even who you’re meeting with changes. The work gets more complex, but it also gets more effective.
