Group Therapy in Addiction Treatment: How It Works and What to Expect

Group therapy is a structured, clinician-led approach used in addiction and mental health treatment, where each person has space to participate at their own pace. It’s also one of the most widely used elements of addiction treatment, with more than 90% of substance use treatment facilities in the U.S. offering it.¹

If you're considering rehab, you may wonder what group sessions are actually like, whether you'll have to talk right away, and how being with other people can help. In a rehab program with group therapy, you can learn practical recovery skills while reconnecting with others.

This guide explains how group therapy works, what to expect, and how to tell whether it fits your needs.

What Is Group Therapy?

Group therapy is a structured form of treatment in which typically six to 12 patients meet regularly with one or more therapists.² In addiction treatment, these sessions give you a place to talk through challenges, practice recovery skills, and learn from others who understand what you're going through. That peer element matters: addiction often thrives in isolation, and treatment in a group can help you rebuild connection.²

In rehab, you might attend group therapy several times a week for as long as you're in treatment, whether that's a 28-day stay or longer. Many programs pair groups with one-on-one therapy. Therapists often use evidence-based approaches like cognitive behavioral therapy (CBT), dialectical behavioral therapy (DBT), and motivational interviewing, a counseling approach that helps you explore your reasons for change.^2,3

Types of Group Therapy

Group therapy sessions often focus on a specific goal or topic. In one group, you might learn anger management skills; in another, you might explore family dynamics or relationship patterns. Some groups are also designed for people with shared identities or experiences, such as teens, women, and veterans.

Most rehab programs use a combination of group therapy approaches rather than relying on a single model.² Groups are typically based on several core models commonly used in addiction treatment:²

• Psychoeducational groups, where you learn about addiction, triggers, and patterns of behavior
• Skills development groups, where you practice coping tools like emotional regulation, communication, and stress management
• Cognitive-behavioral groups, which focus on changing thoughts and behaviors that support substance use
• Support groups, where members share experiences and offer encouragement throughout recovery
• Interpersonal process groups, where therapists use real-time group dynamics to help you understand and change relationship patterns

Some programs also offer relapse prevention groups, which focus on identifying warning signs and preparing for high-risk situations. Your specific group may be open or closed. In open groups, people can join or leave as they enter or exit treatment. Closed groups keep the same members throughout a set period. Both formats can be effective, and many programs offer a mix of both.²

Group Therapy for Addiction

During rehab, you and your group may learn practical skills to support addiction recovery, including coping with cravings, identifying triggers, relapse prevention strategies, and stress management.² A therapist might guide you through role-playing exercises, such as responding to high-risk situations or managing conflict, so you can practice healthier responses before those moments happen in real life.

Group therapy can also help if you have co-occurring mental health conditions, meaning you experience both a mental health condition and a substance use disorder at the same time.⁴

Depending on the group, you might talk about anxiety, depression, trauma, or how your mental health and substance use affect each other. Treatment for co-occurring disorders often focuses on building coping and interpersonal skills to support recovery.⁵ In a group setting, sharing your experiences with others who understand what you’re going through may help reduce isolation and keep you engaged in recovery.²

What Happens in Group Therapy?

In many group therapy sessions, you’ll meet with your peers and a therapist in a structured setting. Many groups follow a consistent format. Sessions often begin with a brief check-in, where you might share how you’re feeling, what’s been challenging, or any progress you’ve made since the last meeting.

The therapist then guides the main activity, which could include a lesson, worksheet, role-play, or group discussion focused on building recovery skills. These sessions often emphasize reflection and practical strategies you can use between meetings.³

Groups typically end with a short reflection, takeaway, or plan for the time ahead. During your first session, you’ll likely make introductions and learn the group’s expectations and guidelines. While topics may change, the overall structure often stays familiar.

In many rehab settings, sessions last about 60 to 90 minutes and may happen multiple times per week.² In many programs, you'll attend these meetings in addition to 1:1 therapy and complementary treatments, like art or music therapy.

A Safe Space to Make Mistakes

Group therapy gives you a place to try out new ways of relating to people while you're still in treatment. That matters in addiction recovery, because many of the hardest moments happen in relationships: setting boundaries, asking for help, responding to conflict, or tolerating uncomfortable emotions without using substances. In group, those challenges can show up in real time, and your therapist can help you work through them instead of only talking about them later.

Programs like All Points North Lodge, for example, encourage patients to practice these skills in a supportive environment with clinician guidance. That feedback can help you notice old patterns, make small changes, and build confidence before you bring those skills into daily life.

The Role of a Group Therapist

In a rehab setting, group therapists do more than lead a conversation. They guide the structure and pace of each session, help the group stay focused, and make sure everyone has a chance to participate. If one person dominates the discussion, withdraws, or reacts strongly to others, the therapist can step in to support the group and keep interactions constructive.²

Therapists in addiction treatment also understand the specific challenges of recovery, including cravings, relapse risk, shame, family stress, and co-occurring mental health conditions. They model healthy communication, encourage respectful and honest feedback, and help members learn from one another in a supportive environment. Rather than giving advice or taking over the conversation, they act as guides, maintaining structure while making space for meaningful connection.²

How to Prepare for Group Therapy

Before your first group session, you can expect some basic guidelines, like confidentiality, respectful listening, and taking turns to speak. Most groups ask members to keep what’s shared private, listen without interrupting, avoid talking over each other, and speak from personal experience rather than judging or trying to fix others. While sharing is encouraged, you can choose how much you want to open up.

In your first session, you may introduce yourself, hear the group norms, and spend more time listening than talking. It’s okay to come with questions, like how the group works, what confidentiality means in practice, or what to do if a topic feels too intense. Try to arrive on time and give yourself a few minutes to settle in.

Many people feel nervous at first, and that’s completely normal. It doesn’t mean group therapy isn’t a good fit. For many, that discomfort eases after a few sessions as you get to know the therapist and other members and start to feel more comfortable with the process.

The Benefits of Group Therapy

Individual therapy can help you understand your own thoughts and patterns. Group therapy adds something different: live connection. Because recovery happens in relationships (with family, friends, coworkers, and community), healing with others can teach lessons you may not get on your own. As SAMHSA notes, people are inherently social, and connection in a group setting can support recovery over time.² In this way, the group itself becomes part of the treatment, not just the setting where it happens.

Interpersonal Skills

Group therapy can help you practice the skills that make everyday recovery more sustainable. That may include active listening, expressing emotions clearly, setting boundaries, receiving feedback, and working through conflict. These skills matter in treatment, but they also carry into work, friendships, parenting, and romantic relationships.

Because everyone in the room is working toward recovery, group therapy can also help reduce the sense of stigma many people carry about addiction.² You may begin to see that you’re not the only one dealing with shame, fear, or relationship challenges. That shared understanding can support connection, honesty, and emotional growth.²

Treatment for Co-Occurring Conditions

Addiction often co-occurs with other mental health concerns.^4,5 So if you're healing from more than one diagnosis, you might attend rehab for co-occurring mental health and substance use conditions. For example, some programs treat patients with both addiction and depression, or addiction and post-traumatic stress disorder (PTSD).

In these programs, group therapy may address more than substance use alone. A session might focus on managing anxiety, understanding trauma responses, or noticing how mood symptoms affect cravings. Healing alongside people with similar diagnoses can reduce isolation and help you stay engaged in care.

Positive Peer Pressure

Peer pressure can be helpful in recovery. Positive peer influence can help you keep going when motivation dips. When you spend time with people who are also working toward sobriety, honesty, and healthier coping, their choices can reinforce your own. Group members may also notice warning signs you miss in yourself, like isolation, defensiveness, or thought patterns that can show up before relapse.

That accountability works both ways. You can support other people without judging them, and they can do the same for you. Over time, that mutual investment can strengthen your commitment to change. Connecting with peers in treatment can encourage abstinence from drug use, which is one reason group therapy is a common part of addiction care.²

Support for Teens in Recovery

The social side of group therapy can be especially helpful for teens and young adults. At that stage of life, peer relationships are a major part of confidence, emotional development, and identity. When addiction or mental health symptoms interrupt those connections, teens can feel cut off quickly.

For teens and young adults, group therapy can rebuild connection and make it easier to ask for support.

According to experts at Paradigm Teen & Young Adults Treatment, addiction can distance teens from their peers. Because of this, the willingness, openness, and courage to actively re-engage in their peer community is a crucial aspect of recovery and healing. Group therapy gives teens a structured place to practice vulnerability, build trust, and learn that asking for support is a strength. That lesson can stay useful well beyond adolescence.

Limitations of Group Therapy

Group therapy can work differently for different people. Some people find it helpful right away, while others may feel overwhelmed at first or need more individual support early in treatment.

In some cases, individual therapy may be a better starting point. People who have experienced trauma, for example, may need time to feel safe before sharing in a group. Those with social anxiety might take longer to feel comfortable participating. People experiencing active psychosis, such as delusions or hallucinations, may find it harder to engage in a group setting and may benefit from additional support or individualized care.²

Group dynamics can also be challenging at times. You may relate more to some people than others, and occasionally another member’s story or behavior can feel triggering. Privacy is another important consideration. If confidentiality feels especially important to you, or if you prefer more privacy, individual therapy may feel like a better fit.

Group therapy can still be a valuable part of treatment. The most effective approach depends on your needs, comfort level, and recovery goals.²

Finding the Right Support for Your Recovery

Recovery is personal, and the right treatment plan can look different from one person to the next. Some people do best with a mix of group therapy, individual therapy, and complementary treatments. Others may need more privacy or a slower pace before group feels comfortable.

If group therapy is part of your program, it can offer more than conversation. It can help you practice honesty, build healthier relationships, and feel less alone while you work toward change. And if you're still exploring options, comparing different approaches can help you find the level of support that fits you best.
