Substance use disorders are highly treatable chronic health conditions, not moral failings or a lack of willpower. Evidence‑based treatment significantly improves the chances of achieving and maintaining recovery, especially when care is ongoing rather than a one‑time event.(Source)

However, it is difficult to assign a single “success rate” to addiction treatment because:

• There is no standard definition of success. Some programs define success as completing a rehab program, others as a certain period of abstinence, and others as improvements in health, relationships, and functioning.
• Follow‑up periods vary. A program that only tracks people for 30 days or 6 months after discharge will report very different numbers than one that follows people for several years.
• Recovery is a long‑term process. Like other chronic illnesses, substance use disorders often involve periods of remission and recurrence (relapse). A relapse does not mean treatment failed; it often means treatment needs to be adjusted.(Source)

Because of these differences, it is more accurate to talk about recovery outcomes and relapse rates than a single, simple success percentage. What matters most is finding a comprehensive, individualized treatment plan and staying engaged in recovery supports over time.

Substance use continues to be a major public health concern in the United States.

• In recent years, more than 100,000 people in the U.S. have died annually from drug overdoses, driven largely by synthetic opioids such as illicitly manufactured fentanyl.(Source)
• Drug overdose remains a leading cause of injury‑related death in the United States.(Source)
• Alcohol‑related deaths have also risen significantly over the past decade, with tens of thousands of deaths each year directly attributable to alcohol use.(Source)

At the same time, a large treatment gap remains:

• Millions of Americans meet criteria for a substance use disorder each year, yet only a minority receive any specialty addiction treatment.(Source)

This gap is often due to stigma, lack of access, financial barriers, or fear of seeking help. Engaging in a structured addiction treatment program—whether inpatient, residential, or outpatient—substantially improves the odds of reducing or stopping substance use and rebuilding a healthy life.(Source)

Looking at specific substances can help clarify the risks and the need for treatment. The statistics below reflect recent research and national data available through 2025.

Alcohol Use Disorder

• Each year in the U.S., tens of thousands of deaths are directly attributable to alcohol, including from liver disease, alcohol‑related injuries, and poisoning.(Source)
• Millions of adults meet criteria for an alcohol use disorder (AUD), yet only a fraction receive specialized treatment in a given year.(Source)
• Globally, alcohol is responsible for a significant percentage of all deaths and contributes to hundreds of disease and injury conditions.(Source)

Because alcohol is socially accepted and easily accessible, many people underestimate its risks. Evidence‑based treatment—including medical care, counseling, and medications for AUD—can greatly improve outcomes and reduce the risk of serious health complications.(Source)

Opioid Use Disorder

• The U.S. continues to experience an opioid overdose crisis, with tens of thousands of opioid‑involved deaths each year.(Source)
• Millions of people worldwide are estimated to have an opioid use disorder at some point in their lives.(Source)

Medications for opioid use disorder (MOUD)—such as buprenorphine, methadone, and extended‑release naltrexone—combined with counseling and recovery support, are considered the gold standard of care and significantly reduce overdose risk and improve retention in treatment.(Source)

Heroin and Illicit Fentanyl

• A substantial proportion of people who use heroin develop an opioid use disorder, reflecting the drug’s strong reinforcing effects on the brain’s reward system.(Source)
• In recent years, many fatal overdoses previously attributed to heroin now involve fentanyl or fentanyl‑contaminated heroin, which is far more potent and increases overdose risk.(Source)

Because of these risks, professional treatment and access to MOUD and overdose‑reversal medications (such as naloxone) are critical.

Cocaine and Stimulants

• Cocaine is frequently involved in polysubstance overdoses, especially when combined with opioids.(Source)
• Young adults have historically shown higher rates of cocaine use compared with some other age groups, though patterns can shift over time.(Source)

While there are currently no FDA‑approved medications specifically for cocaine or methamphetamine use disorders, behavioral therapies and comprehensive treatment programs can still be highly effective.(Source)

Addiction treatment is most effective when it is comprehensive, individualized, and long‑term. Research has identified several key factors that improve recovery outcomes:

• Evidence‑based therapies. Approaches such as cognitive behavioral therapy (CBT), contingency management, motivational interviewing, and family‑based therapies have strong evidence for reducing substance use and improving functioning.(Source)
• Medication‑assisted treatment (MAT) / medications for addiction treatment. For opioid and alcohol use disorders, FDA‑approved medications can reduce cravings, prevent withdrawal, and lower the risk of relapse and overdose when combined with counseling and support.(Source)
• Integrated mental health care. Many people with substance use disorders also experience depression, anxiety, trauma‑related conditions, or other mental health concerns. Treating both substance use and mental health together leads to better outcomes than treating either alone.(Source)
• Length and continuity of care. Longer engagement in treatment and step‑down levels of care (for example, residential treatment followed by intensive outpatient and then standard outpatient) are associated with better long‑term outcomes.(Source)
• Recovery support and community. Ongoing support—such as alumni programs, peer recovery groups, 12‑step or alternative mutual‑help groups, and sober social networks—helps people maintain motivation and accountability after formal treatment ends.(Source)

At Cardinal Recovery, treatment plans are designed to address the whole person: substance use, mental health, physical health, relationships, and life skills. This holistic approach supports not just abstinence, but a more stable and fulfilling life in recovery.

Relapse is common in addiction recovery and should be understood in the context of other chronic illnesses.

• Studies suggest that relapse rates for substance use disorders are roughly 40–60%, similar to relapse or recurrence rates for conditions such as hypertension, asthma, and type 2 diabetes.(Source)

This comparison is important:

• A relapse is not a moral failure or proof that treatment “didn’t work.”
• Instead, relapse is often a signal that treatment needs to be adjusted—for example, by changing medications, increasing therapy intensity, adding recovery supports, or addressing new stressors.

Effective treatment is flexible and responsive. As a person’s life circumstances, stressors, and health needs change, their treatment plan should evolve as well. Ongoing care—rather than a single episode of treatment—offers the best chance of sustained recovery.(Source)

Comprehensive treatment programs help people:

• Understand the underlying factors driving substance use
• Build coping skills for cravings and stress
• Repair relationships and rebuild social support
• Address medical, psychiatric, and legal or vocational issues

These changes often continue long after formal treatment ends and are important markers of success, even if occasional slips or relapses occur along the way.

Opioid use disorder (including dependence on prescription pain medications, heroin, and illicit fentanyl) is a chronic condition with a high risk of relapse, particularly without ongoing treatment.

Research shows that:

• People with opioid use disorder who receive medications such as methadone or buprenorphine have significantly lower rates of overdose and higher treatment retention than those who do not receive these medications.(Source)
• Discontinuing these medications too early is associated with increased risk of relapse and overdose, highlighting the importance of long‑term, individualized medication plans.(Source)

While some studies have reported very high relapse rates among people with opioid use disorder—especially when treatment is brief or does not include medication—these numbers improve substantially when evidence‑based medications and ongoing support are used.(Source)

The key points to remember are:

• Opioid addiction is manageable, even if it is not “cured” in the traditional sense.
• Many people with opioid use disorder go on to live stable, substance‑free, and fulfilling lives with the help of medication, therapy, and recovery support.
• A relapse does not mean someone cannot recover; it means their treatment plan may need to be strengthened or adjusted.

Understanding why relapse happens can reduce shame and help you prepare for challenges in recovery.

The Brain’s Reward System

• When a person uses these substances, large surges of dopamine and other neurotransmitters create powerful feelings of pleasure or relief.
• Over time, the brain adapts, leading to tolerance (needing more of the substance to get the same effect) and withdrawal symptoms when use stops.
• Environmental cues—such as people, places, or emotions associated with past use—can trigger intense cravings, even after a period of abstinence.(Source)

These brain changes help explain why relapse can occur even when someone is highly motivated to stay sober.

Common Triggers for Relapse

• Stress and unresolved trauma
• Lack of a supportive network or spending time with people who are still using
• Untreated mental health symptoms, such as depression, anxiety, or PTSD
• Major life changes or crises, such as job loss, relationship conflict, bereavement, or financial strain
• Overconfidence (“I can handle just one”) and gradual erosion of recovery routines

Therapy and recovery planning help people identify their personal triggers and develop coping strategies to manage them. Skills such as emotion regulation, stress management, communication, and boundary‑setting are central to preventing relapse.(Source)

While no program can guarantee a specific outcome, there are clear steps you can take to improve your chances of long‑term recovery.

Build a Strong Support Network

• Surround yourself with people who support your recovery—family, friends, peers in recovery, sponsors, and professionals.
• Consider joining mutual‑help groups (12‑step or non‑12‑step) or peer recovery communities to stay connected and accountable.(Source)

Choose Comprehensive, Personalized Treatment

• Medical assessment and, when appropriate, medications for addiction treatment
• Individual, group, and family therapy
• Mental health evaluation and treatment
• Education about addiction, relapse prevention, and life skills
• Aftercare planning and alumni or continuing care services

Comprehensive, individualized care is associated with better outcomes than brief, one‑size‑fits‑all approaches.(Source)

Change Your Environment

• Avoid people, places, and situations strongly associated with past substance use, especially early in recovery.
• Create new routines that support sobriety—healthy sleep, nutrition, exercise, and meaningful daily activities.
• If your home environment is unsafe or unsupportive, consider sober living or other structured housing options during early recovery.(Source)

Understand Your Addiction

• Learn how your substance of choice affects your brain and body.
• Work with a therapist to identify your triggers, patterns, and underlying emotional or situational drivers of use.
• Keep a journal or recovery log to track cravings, moods, and successes. This can help you and your treatment team adjust your plan over time.

If you experience a relapse or slip, it can feel discouraging—but it does not erase the progress you have made. Many people who achieve long‑term recovery have experienced one or more relapses along the way.(Source)

Here are steps that can help you get back on track:

1. Stop Use as Quickly and Safely as Possible

• If you have returned to use, seek help immediately—especially if opioids, alcohol, or multiple substances are involved.
• Be aware that your tolerance may have decreased during abstinence, which can increase overdose risk if you return to previous levels of use.(Source)
• In some cases, medical supervision or detox may be necessary to stop safely.

2. Be Compassionate With Yourself

• Recognize that relapse is a common part of the recovery process for many people.
• Instead of viewing relapse as a failure, try to see it as information about what needs to change in your recovery plan.
• Reflect on what led up to the relapse—stressors, emotions, people, places, or changes in routine—and consider writing about it so you and your treatment team can learn from it.

3. Reach Out for Support

• Contact a trusted person: a sponsor, therapist, counselor, family member, or close friend who supports your recovery.
• If you are in treatment or have completed a program, reach out to your treatment center or alumni program to discuss next steps.
• If you are in immediate danger or at risk of overdose, seek emergency medical help right away.

Relapse can be a turning point that leads to a stronger, more resilient recovery when it is met with honesty, support, and an updated treatment plan.

Shame is common in addiction, but it can also keep people stuck. If you are reading about recovery success rates and exploring treatment options, you have already taken meaningful steps toward change.

You can be proud that:

• You are acknowledging the impact of substance use on your life.
• You are seeking information and support instead of staying silent.
• You are considering or engaging in treatment, even if you feel uncertain or afraid.

Recovery is built one decision at a time. Every step you take—asking questions, making a phone call, attending a group, or completing a day sober—is part of your success story.

Beginning treatment can feel intimidating, but you do not have to do it alone. Many people who are now thriving in recovery once felt the same fear, doubt, and uncertainty you may be feeling right now.

At Cardinal Recovery, we offer:

• Comprehensive addiction treatment programs that address substance use, mental health, and overall well‑being
• Evidence‑based therapies and addiction‑focused counseling in both individual and group settings
