What happens in rehab depends on your needs, but care often starts with an assessment, withdrawal care if needed, therapy, and a plan for ongoing support. In a residential treatment program, you live at the treatment center while you get care.
Not knowing what to expect stops many people from seeking treatment. In 2025, only about 1 in 6 people aged 12 or older who needed substance use treatment received it, according to the Substance Abuse and Mental Health Services Administration [1]. Below, we walk through each step, from intake to discharge.
The Rehab Process, Step by Step

Many treatment programs move through four stages: intake, detox, therapy, and aftercare. The order is similar across rehab centers, but the time each stage takes depends on you. For the bigger picture first, our guide explains what is residential treatment and who it fits.
Intake and Assessment
On your first day, a clinician asks about your substance use, physical health, mental health and history. This first talk sets your personalized treatment plan. Some centers call it a customized treatment plan.
The team also checks for co-occurring disorders, which means a mental health condition and a substance use problem at the same time. Spotting co-occurring mental health issues early lets the team address underlying issues, not just the drinking or drug abuse.
Medical Detox
If you may have withdrawal symptoms, a clinician assesses what care you need. Medical detox manages withdrawal, sometimes with medicine and round-the-clock monitoring. Physical dependence does not always require inpatient detox, and ongoing medication treatment can be started for opioid use disorder. At Mile High, detox and medical stabilization take place with partner providers before residential care.
Detox is only the start. The National Institute on Drug Abuse calls it “only the first stage of addiction treatment” [2]. On its own, detox rarely leads to lasting recovery, so the therapeutic process that comes next matters most.
What Is a Typical Day in Inpatient Rehab Like?
A typical day in inpatient rehab is busy and predictable, and that structured environment is part of the point. When every hour has a plan, there is less room for cravings and old habits.
Here is a sample daily schedule. Times vary, but meals, groups and quiet time usually happen at set hours:
| Time | What Happens |
|---|---|
| 7:00 a.m. | Wake up, breakfast, medicine check |
| 8:30 a.m. | Morning group or goal-setting meeting |
| 10:00 a.m. | Group therapy sessions or skills classes |
| 12:00 p.m. | Lunch and a short break |
| 1:00 p.m. | Individual therapy or a medical visit |
| 3:00 p.m. | Activity such as fitness, art or music therapy |
| 5:00 p.m. | Dinner |
| 7:00 p.m. | Support groups such as Alcoholics Anonymous or Narcotics Anonymous |
| 9:00 p.m. | Free time, then lights out |
This schedule is an example rather than Mile High’s exact timetable. Ask our admissions team about current weekday and weekend activities. Families often ask how to help during this time, and our chapter on what to say to someone in rehab gives words that help.
Mornings and Group Therapy
Many programs start the day between 6 and 7 a.m., with breakfast and a morning group. Group therapy takes up a big part of the day in many rehab facilities. In group sessions, people share personal stories, practice new skills, and hold each other to their goals.
Group counseling can feel strange at first, but many people come to value it. Hearing someone describe your own struggle can ease shame and show you are not alone in the recovery process.
Individual Therapy and Behavioral Therapy
Individual therapy frequency and session length vary by program and treatment plan. Sessions can help you explore factors related to your substance use, such as trauma, grief or stress, while building coping skills. Many centers call this individual behavioral therapy.
Cognitive behavioral therapy (CBT) is common. It works on the thoughts behind your actions and helps you spot your triggers. Your therapist may also use other kinds of therapy, such as these:
- Dialectical behavior therapy (DBT), which builds skills for handling strong emotions
- Motivational interviewing, which helps you find your own reasons to change
- Family therapy, which brings loved ones into the treatment process
- Trauma therapy such as EMDR when past events drive the drinking or drug use
Afternoons, Evenings and Free Time
Afternoons often mix skills classes with something active, like exercise, art, yoga, mindfulness or music therapy. These help you rebuild healthy routines and learn new coping mechanisms that do not involve alcohol or drugs.
Evenings usually include 12-step or other peer support groups. Free time is limited, and many centers restrict phones early on. We explain why in our chapter on phone rules in rehab.
How Long Drug and Alcohol Rehab Lasts

Length depends on your progress, not a fixed number of days. The National Institute on Drug Abuse says many people need at least 3 months in treatment to cut down or stop their drug use [2]. That time can include residential care followed by outpatient treatment. We usually recommend at least 30 days in our residential treatment program, and some people stay longer when their care team thinks it will help.
Paying for Residential Treatment in Colorado
Insurance coverage is a common worry. Health First Colorado is the state’s Medicaid program. It has covered residential and inpatient treatment for substance use disorder since January 1, 2021 [3].
Authorization rules depend on the service and health plan, and continued coverage is reviewed for medical necessity. Ask the program and your Medicaid plan how authorization works. Many private plans also cover residential rehab, and a quick benefits check before you attend rehab shows what yours pays for.
Leaving Rehab and Stepping Down
Before you leave, your team builds an aftercare plan with you, so discharge does not come as a surprise. The plan usually covers:
- Outpatient therapy or a day program
- Support groups and sober contacts
- Any medicine you take
- What to do if cravings hit
Outpatient Rehab Programs After Residential Care
Many people step down to outpatient rehab programs instead of going home with no support. Outpatient rehab lets you live at home while you keep going to treatment, as our post on IOP, PHP and residential care explains. Under Medicare rules, partial hospitalization means at least 20 hours of care a week, and intensive outpatient at least 9 [4].
These steps let you practice new coping strategies in daily life with a support network still in place. That makes it easier to maintain long-term sobriety once the recovery journey moves home.
If You Want to Leave Early
Some people feel ready to go before their team does. Rehab is usually voluntary, so the choice is yours, though some stays are court-ordered. Talk with your team first, because there are often choices short of leaving treatment early.
Who Drug or Alcohol Addiction Rehab Is For
A substance abuse treatment program helps people with alcohol addiction or drug addiction. It also treats the mental health disorders that often come with them. Some residential treatment centers run groups for young adults, veterans, or LGBTQ+ adults.
The word rehab can also mean care after an injury or surgery. In that kind of rehab, physical therapy helps you get strong again, and occupational therapy helps with daily tasks like dressing. This article is about addiction rehab at rehabilitation centers that treat substance use disorder.

Frequently Asked Questions
What Happens When You First Go to Rehab?
On the first day, you complete an intake assessment covering your substance use, health, and mental health. Staff check you in, explain the house rules, and show you your room. If you need detox, staff arrange the appropriate withdrawal care before residential admission. At Mile High, partner providers handle detox and medical stabilization, and the residential team then develops your treatment plan.
What Do You Do All Day in Drug Rehab?
Much of the day is spent in therapy. That includes group and individual therapy, skills classes, and activities like exercise or art. Meals happen at set times, and evenings often include support groups. Free time is limited, especially in the first week.
What Is the Hardest Part of Rehab?
For many people, the first week is hardest because of withdrawal symptoms, cravings, and being away from home. Opening up in group therapy can also feel hard at first. Both usually get easier as your body settles and you build trust with staff and peers.
Is Inpatient Treatment the Same as Residential Rehab?
People sometimes use the terms interchangeably, but they can describe different levels of care. Inpatient treatment generally involves hospital-level medical or psychiatric care. Residential rehab is live-in treatment in a nonhospital setting, with support and therapy that vary by program. Ask which services and level of care a center provides.
