When a loved one is struggling with a substance use problem and is not seeking help, families often feel stuck between doing nothing and doing something that might make things worse. An intervention, in its broadest sense, is simply a deliberate attempt by people who care about someone to encourage them toward treatment and support.
There is no single intervention approach that works for everyone. How well any approach works depends on the person struggling, their relationship with the people involved, the specific substance use situation, and how the intervention is carried out. What matters most is that families take the time to understand the options available to them and choose the approach that feels most appropriate for their loved one and their family dynamic.
The three most recognised approaches are the Johnson Institute Intervention, Community Reinforcement and Family Training (CRAFT), and Motivational Interviewing. Each works differently, involves different levels of professional support, and suits different situations. What follows is an overview of each approach, including how a family would actually put it into practice.
The Johnson Institute Intervention
The Johnson Institute Intervention, developed by Dr. Vernon Johnson in the 1960s, is the approach most people picture when they hear the word “intervention.” It is a structured, planned meeting in which people close to the person, typically family members, friends, and sometimes colleagues, come together to confront them directly about the impact their substance use has had, and to present a clear request that they accept treatment.
The meeting is typically organised with the help of a professional interventionist and kept secret from the person until it takes place. Each participant prepares a statement describing specific ways the substance use has affected them, framed around care rather than blame. The session ends with a treatment option already arranged, so that if the person agrees to seek help, they can act on it immediately.
How it Works in Practice
- A small team of people who have a genuine relationship with the person is assembled, usually with the guidance of a trained interventionist
- The team meets in advance to prepare, learn about addiction, and agree on what each person will say
- Each participant writes a personal statement describing the impact of their loved one’s substance use, focused on specific examples rather than general accusations
- The team agrees in advance on what boundaries or consequences they are prepared to follow through on if the person refuses help
- On the day, the meeting takes place without the person’s prior knowledge
- Treatment options are arranged and ready before the intervention begins
Things to Consider
The Johnson model has a long history and has been shown to be effective at getting people to enter treatment. A peer-reviewed study published in the American Journal of Drug and Alcohol Abuse found that people who underwent the Johnson Intervention were more likely to enter treatment than those referred through four other methods.
That said, this approach is not right for every situation or every family. The CCSA notes that families who attempt the Johnson model often find it difficult to follow through when the moment arrives, and that the confrontational nature of the approach can be a barrier for many. It also places significant emotional weight on the people delivering the intervention. A professional interventionist can help families assess whether this approach is appropriate for their specific situation and guide them through the process if they decide to proceed.
Community Reinforcement and Family Training (CRAFT)
Community Reinforcement and Family Training, known as CRAFT, is a therapeutic approach developed for family members and close friends of people with substance use problems who are unwilling to seek help. Unlike the Johnson model, CRAFT does not involve a confrontational meeting. Instead, it works gradually and indirectly, coaching the concerned family member or friend, referred to in the approach as a Concerned Significant Other or CSO, on how to shift the home environment in ways that make sobriety more rewarding and substance use less so.
CRAFT has three core goals: to improve the quality of life of the concerned family member, to reduce the loved one’s substance use, and to encourage the loved one to engage in treatment. Importantly, even when the loved one does not enter treatment, family members who go through CRAFT typically report improvements in their own wellbeing.
How it Works in Practice
CRAFT is delivered by a trained therapist working with the concerned family member, not with the person struggling with substance use. Sessions focus on building practical skills, including:
- Learning to recognise and reward their loved one’s sober behaviour through positive reinforcement, rather than inadvertently reinforcing substance use
- Developing positive communication skills to replace patterns of nagging, threatening, or pleading
- Allowing natural consequences of substance use to occur, rather than shielding the loved one from them
- Identifying windows of opportunity when the loved one may be more open to the idea of treatment, and knowing how to raise it in those moments
- Building the family member’s own quality of life and self-care, independent of their loved one’s choices
According to the CCSA’s evidence summary on CRAFT, CRAFT has been shown to be effective across a range of substances including alcohol, opioids, cocaine, cannabis, and stimulants, and across different types of relationships including spouses, parents, and siblings.
Things to Consider
According to the PMC review of Community Reinforcement approaches, CRAFT successfully engaged approximately two-thirds of treatment-refusing individuals into treatment, and was 2 to 3 times more successful than the traditional Al-Anon model and the Johnson Intervention at doing so. Family members also reported reductions in their own depression, anger, and anxiety regardless of whether their loved one entered treatment.
CRAFT requires a commitment of several sessions with a trained therapist and works best when the family member is consistent in applying its techniques. It is not a quick fix and it is not something families are expected to navigate on their own. Finding a therapist trained in CRAFT is the recommended starting point.
Motivational Interviewing
Motivational Interviewing, commonly referred to as MI, is a conversational approach originally developed for use by counsellors and health care providers to help people who are ambivalent about changing their behaviour. While it is not a family intervention model in the same structured sense as Johnson or CRAFT, its principles are increasingly used to guide how family members communicate with a loved one about their substance use, and many therapists incorporate MI techniques into family support work.
At its core, MI is built on the idea that pressure and confrontation tend to increase resistance, while empathy, curiosity, and open conversation create the conditions where a person is more likely to explore change on their own terms. According to the CCSA’s evidence summary on Motivational Interviewing, MI was developed in response to conventional treatment approaches that relied on confrontation, and is grounded in the understanding that ambivalence about change is normal, not a sign of failure or denial.
How it Works in Practice
MI is typically delivered by a trained counsellor, but its core principles can also inform how family members approach conversations with their loved one. These principles include:
- Listening more than talking, and asking open questions that invite the person to reflect rather than defend themselves
- Expressing genuine empathy and curiosity about the person’s experience, without judgment
- Avoiding the urge to argue, correct, or push for change, which tends to produce pushback
- Reflecting back what the person says in a way that helps them hear themselves and explore their own ambivalence
- Recognising and gently drawing attention to the gap between where the person is and where they want to be, without forcing the point
CAMH’s guidance on motivation and change describes how a person’s readiness to change moves through stages, from not yet considering change, to thinking about it, to preparing to act. Understanding where a loved one is in that process can help family members calibrate their approach, meeting the person where they are rather than where the family wants them to be.
Things to Consider
MI is not a one-conversation fix. It is a style of engagement that takes practice and patience. For family members, the most valuable takeaway from MI principles is often the shift away from pressure and ultimatums toward genuine connection and curiosity. Many families find it helpful to work with a counsellor who uses MI both to support their own wellbeing and to learn how to apply these communication principles at home.
Professional Interventionists: When to Consider One and What to Look For
Professional interventionists are practitioners who specialise in working with families to plan and facilitate the process of engaging a loved one in treatment. In Canada, professional interventionists vary in their training, credentials, and approaches. Some are trained in structured family-based models like CRAFT; others work within more traditional frameworks like the Johnson model; others draw on motivational interviewing principles. Understanding which approach a practitioner uses, and whether it feels right for your family, is an important part of choosing who to work with.
When considering working with a professional interventionist, the following questions can help you find someone whose approach and values align with your situation:
- What model do you use, and why? A good interventionist should be able to explain their approach clearly, describe what the process will look like, and talk about how they adapt to different situations and families. Understanding their model helps you assess whether it fits your loved one and your family dynamic.
- What training and credentials do you hold? Registered social workers, addiction counsellors with specific intervention training, and psychologists with addiction specialisation are all credible backgrounds. Ask specifically about training in the approach they use.
- How do you talk about the person with the substance use problem? Language that is respectful, non-shaming, and focused on the person’s capacity for change is a good sign. An interventionist who speaks about your loved one with empathy and nuance is likely to bring that same quality to the intervention itself.
- Can you speak to outcomes you have seen with families you have worked with? An experienced interventionist should be able to speak openly about what success looks like in their work, what realistic expectations are, and how they have supported families through both positive outcomes and more difficult ones. Be cautious of anyone who guarantees results or presents intervention as a straightforward process with a predictable outcome.
- What happens if the person does not agree to treatment? A quality interventionist will have a clear plan for this outcome and will not treat it as a failure. For a significant proportion of interventions, the first conversation is the beginning of a longer process, not a single decisive moment. Ask how they support families through continued engagement after an initial refusal.
Taking Care of Yourself: The Part Families Often Forget
When a loved one is struggling with a substance use problem, the natural instinct is to focus everything on them, on getting them help, on keeping them safe, on finding the right approach. What often gets lost in that focus is the toll this takes on the people around them.
Family members and close friends of people with substance use problems commonly experience significant stress, anxiety, depression, and relationship strain. These are real health consequences, and they deserve attention in their own right, not just as a means to better support the person with the substance use problem.
Taking care of yourself is not a distraction from helping your loved one. In many ways it is part of it. People who are supported, less overwhelmed, and looking after their own wellbeing are better able to sustain the kind of long-term, patient engagement that most recovery journeys require. But more importantly, you matter independently of what your loved one chooses to do.
In Canada, there are several sources of support available specifically for family members. CAMH’s Family Service offers educational resources, coaching, and brief individual counselling for anyone concerned about a loved one’s substance use, and accepts self-referrals. Al-Anon and Nar-Anon are peer support groups for family members and friends affected by someone else’s drinking or drug use, available in communities across Canada. Community mental health programs and addiction counsellors can also provide individual support tailored to your situation.
Reaching out for support for yourself is not giving up on your loved one. It is recognising that this is genuinely hard, and that you deserve care too.
What Works Is More Hopeful Than What’s on Television
The evidence on engaging treatment-resistant loved ones is actually more hopeful than the popular narrative suggests. Two-thirds of treatment-refusing individuals enter treatment when a family member completes CRAFT. That is a meaningful number. And the approach produces documented improvements in the family member’s own wellbeing along the way, regardless of the outcome for the person they are trying to help.
The path forward for families is to build skills, maintain connection, respond strategically to moments of openness, and take care of their own health, not to force crises or wait for rock bottom. It is harder than a one-day confrontation, and far more likely to work.
Finding the Right Path Forward
There is no single intervention approach that works for everyone, and no guarantee that any one conversation, no matter how well planned or well intentioned, will be the moment everything changes. What the research does tell us is that families who stay engaged, who look after their own wellbeing, and who approach their loved one with patience and consistency give that person the best possible conditions to eventually seek help.
Whether the Johnson model, CRAFT, motivational interviewing principles, or a combination of approaches feels right for your situation, the most important step is finding a professional you trust, someone who listens to your specific situation, explains their approach clearly, and supports your whole family through the process, not just the intervention itself.
Recovery rarely happens in a single moment. It is usually the result of consistent support and patience from people who care. If you are considering an intervention for someone you care about, speaking with a physician, counsellor, or qualified professional interventionist is a good place to start.
