Addiction is treated through a combination of medical care, behavioral therapy, and ongoing recovery support, tailored to the substance involved and the severity of dependence. There is no single treatment that works for everyone, but research consistently shows that staying in treatment for at least 90 days significantly improves outcomes, and longer durations produce even better results. Most effective treatment plans address not just the substance use itself but the psychological patterns and life circumstances that fuel it.
Withdrawal Management: The First Step
For many substances, treatment begins with medically supervised withdrawal, sometimes called detox. This phase manages the physical symptoms that emerge when someone stops using a substance their body has adapted to. Common withdrawal symptoms include nausea, vomiting, anxiety, and insomnia, though the specifics depend on the drug.
Timelines vary considerably. Alcohol withdrawal symptoms typically appear within 6 to 24 hours after the last drink, peak in severity around 36 to 72 hours, and last 2 to 10 days. Heroin and other short-acting opioid withdrawal begins 8 to 24 hours after the last dose and runs 4 to 10 days. Cannabis withdrawal is milder but can persist for one to two weeks. Benzodiazepine withdrawal is among the longest, potentially stretching 2 to 8 weeks for long-acting forms.
Withdrawal management alone rarely leads to lasting recovery. It is best understood as a necessary first step that stabilizes you physically so you can engage in the behavioral and medical treatments that follow.
Medications for Opioid Use Disorder
Three FDA-approved medications treat opioid addiction, and all work by interacting with the same brain receptors that opioids target. They differ in how they activate those receptors, which shapes how they’re used.
Methadone fully activates opioid receptors at a controlled, steady level, reducing cravings and withdrawal without producing the intense high of heroin or fentanyl. It is the most widely used and most studied opioid addiction medication in the world, and the World Health Organization considers it essential. Methadone has traditionally required daily visits to a specialized clinic, but a 2024 federal rule expanded access by allowing up to 7 take-home doses within the first 14 days of treatment, up to 14 doses starting at day 15, and up to 28 doses from day 31 onward. The same rule also permits initial evaluations via telehealth for both methadone (video only) and buprenorphine (video or phone).
Buprenorphine partially activates opioid receptors, meaning its effects plateau at a certain dose. This ceiling effect makes accidental overdose less likely than with methadone, which is one reason it can be prescribed in a regular doctor’s office rather than a specialized clinic. Clinical trials consistently show it reduces illicit opioid use and keeps people engaged in treatment.
Naltrexone takes the opposite approach: it blocks opioid receptors entirely, so using an opioid while on naltrexone produces no pleasurable effect. It’s available as a daily pill or a monthly injection. Because it doesn’t activate opioid receptors at all, there’s no risk of dependence on the medication itself, but you must be fully through withdrawal before starting it.
Medications for Alcohol Use Disorder
Three medications are also FDA-approved for alcohol addiction, each working through a different mechanism.
Naltrexone (the same drug used for opioid addiction) blocks the receptors involved in the pleasurable sensations of drinking. Many people taking it report that alcohol simply feels less rewarding, which reduces cravings over time. It’s available as a daily pill or monthly injection.
Acamprosate helps ease the negative effects of quitting by calming the overexcited brain chemistry that develops after prolonged heavy drinking. The brain becomes hyperactive during early sobriety, which drives anxiety, restlessness, and intense urges to drink. Acamprosate dampens that excitability.
Disulfiram, the oldest of the three (approved in 1949), works as a deterrent. It interferes with how your body breaks down alcohol, causing a buildup of a toxic byproduct that produces nausea and skin flushing if you drink. The anticipation of feeling sick can be enough to help some people avoid alcohol.
During acute alcohol withdrawal, which can be medically dangerous, short-term use of sedating medications helps prevent seizures and other complications by calming the brain’s electrical activity while it readjusts.
Behavioral Therapies
Medication addresses the biological side of addiction. Behavioral therapy addresses the thinking patterns, emotional triggers, and habits that keep someone locked in a cycle of use. Several approaches have strong evidence behind them, and most treatment programs use a combination.
Cognitive behavioral therapy helps you identify the specific thoughts and situations that trigger substance use, then develop practical strategies for handling them differently. It’s one of the most studied and widely used approaches across all types of addiction. Contingency management takes a more direct route: it provides tangible rewards (often vouchers or small financial incentives) for meeting treatment goals like negative drug tests. Research shows this approach is particularly effective for stimulant use disorders, where no FDA-approved medications currently exist.
Motivational interviewing works well for people who feel ambivalent about changing. Rather than confrontation, a therapist helps you explore your own reasons for wanting to change and strengthens your internal motivation. Mindfulness-based treatments teach skills for sitting with cravings and uncomfortable emotions without acting on them. Family and couples therapy addresses the relationship dynamics that often surround addiction, which can either support or undermine recovery depending on how they’re managed.
Levels of Care
Addiction treatment exists on a spectrum of intensity, and matching someone to the right level matters. The standard framework used across the field describes four broad levels.
- Outpatient treatment involves scheduled sessions (individual or group therapy, medication management) while you continue living at home and maintaining daily responsibilities. This works well for people with stable housing, a supportive environment, and mild to moderate severity.
- Intensive outpatient treatment provides more structured programming, often 9 to 20 hours per week, but you still go home at the end of the day. This level suits people who need more support than a weekly appointment but don’t require 24-hour supervision.
- Residential treatment means living at a treatment facility full-time, typically for 30 to 90 days or longer. You receive daily therapy, medical monitoring, and a structured schedule in an environment removed from the triggers of daily life.
- Medically managed inpatient treatment is the most intensive level, provided in a hospital or hospital-like setting with round-the-clock medical and nursing care. This is reserved for severe withdrawal, serious medical complications, or co-occurring conditions that require close monitoring.
People often move between levels as their needs change. Someone might start in residential treatment, step down to intensive outpatient, and eventually transition to standard outpatient care over several months.
Treating Addiction With Co-Occurring Mental Health Conditions
A large portion of people with substance use disorders also have depression, anxiety, PTSD, or other mental health conditions. For years, these were often treated separately: get sober first, then address the mental health issue (or vice versa). That approach consistently produced poor outcomes because the untreated condition would destabilize progress on the other.
Integrated treatment, developed in the late 1980s, addresses both conditions simultaneously with the same treatment team, at the same location. This means your therapist understands how your anxiety fuels your drinking and how your drinking worsens your anxiety, rather than treating each in isolation. Clinical guidelines now widely recommend this integrated approach, though not all treatment facilities have the combined expertise to deliver it.
Recovery Support After Treatment
Formal treatment is the foundation, but long-term recovery typically depends on what happens after a program ends. Several non-clinical support structures help bridge this gap.
Mutual aid groups like Alcoholics Anonymous, Narcotics Anonymous, and similar organizations are the most widely used form of ongoing peer support. They are free, widely available, and research suggests that regular attendance roughly doubles rates of abstinence compared to no participation, with a clear dose-response relationship: more meetings correlate with better outcomes. That said, the spiritual framework of 12-step programs doesn’t resonate with everyone, and secular alternatives like SMART Recovery exist.
Recovery coaches are people with their own lived experience of addiction who have completed formal training. They provide practical guidance, accountability, and emotional support in a way that’s distinct from therapy. Sober living houses offer alcohol- and drug-free group housing where residents support each other’s sobriety while reintegrating into work and community life. These are not treatment facilities. They rely on mutual accountability and peer support rather than clinical programming.
Relapse Is Part of the Pattern
Between 40% and 60% of people treated for substance use disorders experience relapse. That number often surprises people until they learn that relapse rates for hypertension and asthma fall in a similar range. Addiction is a chronic condition, and like other chronic conditions, setbacks don’t mean treatment has failed. They mean the treatment plan needs adjusting, whether that’s increasing the level of care, changing a medication, adding therapy, or intensifying recovery support.
NIDA emphasizes that participation in treatment for less than 90 days is of limited effectiveness for residential and outpatient programs alike. The most successful outcomes come with longer engagement, which often means continuing some form of care (medication, therapy, group support, or a combination) for months or years. Thinking of treatment as a single event rather than an ongoing process is one of the most common and costly misunderstandings about addiction recovery.
