QUICK ANSWER
How long is rehab?
Most residential rehab programs last 30, 60 or 90 days, usually starting with 3 to 10 days of medical detox. Your clinical team sets the plan for each person and will walk you through it at admission. Treatment usually continues after residential care with outpatient programs, because the National Institute on Drug Abuse notes that less than 90 days of total treatment has limited effectiveness for most people.

Why longer usually works better
Addiction changes the brain over months or years, and recovery takes time too. The National Institute on Drug Abuse reports that residential or outpatient treatment lasting less than 90 days has limited effectiveness for most people. That doesn’t mean 90 days in a residential home; it means 90 days or more of care across detox, residential and outpatient together.
What decides the length?
The substance, how long and how heavily it was used, withdrawal risk, co-occurring mental health conditions, past treatment, insurance authorization, and how the person responds week by week. The clinical team reviews progress regularly and recommends a length based on that review, not a fixed number.
What Happens in Rehab, Stage by Stage
Every program is different, and your clinical team sets the plan for each person. Here is a general picture of what treatment often looks like from the family’s side. For a detailed clinical day-by-day guide, see What to Expect in Alcohol Rehab.
When
What your loved one is doing
What it means for you
Early treatment
Medical assessment and, when needed, the start of detox while the body adjusts.
Expect little or no contact at first. This is normal and protects their safety.
Settling in
Detox finishes for many people. A therapist is assigned and the treatment plan is set.
The team may reach out (with consent) to gather family history.
Building the work
Individual therapy, group therapy and the other care set out in the treatment plan.
Communication usually opens up, based on the treatment plan.
Going deeper
Deeper work on trauma and co-occurring mental health. Family therapy begins when appropriate.
You may be invited to family sessions.
Later in treatment
Relapse prevention, life skills and aftercare planning. Family education sessions may be offered.
You help plan the transition home.
What a Day in Residential Treatment May Include
- Morning routine and breakfast
- Group therapy
- Individual therapy
- Meals and community time
- Skills groups, holistic activities or family sessions
- Free time for exercise, journaling and rest
- Evening reflection and time to rest
Schedules vary by phase of treatment and individual clinical needs. Your clinical team sets the plan for each person and will walk you through it at admission.
Can You Have Your Phone in Rehab?
It depends on the program and the stage of treatment. Your clinical team sets the plan for each person and will walk you through it at admission.
DETOX
Early treatment
Outside contact is often limited so the brain and body can stabilize.
RESIDENTIAL
Set for each person
The clinical team sets communication boundaries for each person.
PROFESSIONALS
Schedule-aware contact
Executives and professionals may be able to arrange limited, scheduled contact for work responsibilities when it is clinically appropriate. Ask the admissions team.
If you’re worried about not hearing from your loved one in the first days, that’s normal. Our team can tell you how your loved one’s plan handles communication.
Ask our admissions team about phone and visiting policies: 818-869-2112
Can You Visit Someone in Rehab?
Yes, in most cases, once your loved one is past detox and the clinical team agrees. Visits and family sessions are planned as part of the treatment plan rather than drop-ins.
Before a visit
- Ask the team what time, length and topics are appropriate
- Keep the visit calm. Treatment is hard work, and visits are not the time to settle old arguments
- Bring nothing containing alcohol, and no medications unless the team has approved them
What not to say to someone in rehab
- “When are you coming home?” (pressure to leave early)
- “Do you really think you need to be there this long?”
- Updates about bills, family conflict or problems they can’t solve right now
- Anything that sounds like blame for the past
What helps instead
- “I’m proud of you for doing this.”
- “Take the time you need. We’ve got things handled here.”
- “I’m working on my part too.”
What to Bring to Rehab
Confirm the final list with admissions before arrival.
Bring
- Photo ID and insurance card
- Current medications in their original pharmacy bottles, plus a list of doctors
- 7–10 days of comfortable clothing and layers (laundry is available)
- Comfortable shoes and workout clothes
- Alcohol-free toiletries
- A notebook, a book or two, and photos of family
- Phone numbers of key contacts written on paper
Leave at home
- Alcohol, drugs or anything containing alcohol (some mouthwashes, hand sanitizers, colognes)
- Weapons
- Expensive jewelry and large amounts of cash
- Over-the-counter supplements not approved by the medical team
What to send someone in rehab
A handwritten letter, photos, a book. Check with the team before sending packages.
A letter to your loved one can be one of the most meaningful things they receive. Keep it short and loving: one good memory, one thing you’re proud of, and that you’ll be there when they come home.

Get the ChecklistPrivacy: What the Team Can Tell You
Addiction treatment records have some of the strongest privacy protections in U.S. law, under HIPAA and a federal rule called 42 CFR Part 2. This means the clinical team can only share information with you if your loved one signs a written consent (a release of information).
Under federal privacy rules for addiction treatment (42 CFR Part 2), the team can only share information your loved one has authorized in writing. Ask them to sign a release naming you if they want you updated. If they say no, the team can still listen to you and take your information into account, even if they can’t share updates back.
How to Support Someone in Rehab
- Take part in family therapy. It is one of the strongest ways to support long-term recovery. Family Therapy ›
- Don’t ask them to leave early. Work, money and household problems can wait.
- Get your own support. Al-Anon, Nar-Anon or a family therapist. Family Support for Addiction ›
- Prepare the home. Remove alcohol and unused medications before they return.
- Learn about aftercare and be part of planning it.
Family Therapy During Treatment
Addiction affects the whole family, and recovery is stronger when families are part of it. During treatment, families can take part in family sessions arranged by the clinical team. These sessions give everyone a safe place to be heard, and they teach practical communication and boundary-setting skills that help at home after treatment.
Families can also help plan aftercare, so the household is ready for what comes next: how to talk about hard topics, which boundaries stay in place, and where your loved one and the family will get support. Your loved one’s written consent decides what the team can share, so ask them to sign a release if you want to take part. Your clinical team sets the plan for each person and will walk you through it at admission.
The Days After Treatment Matter Most
The first weeks after leaving residential treatment carry real risk. Tolerance drops during treatment, so returning to the same amount of a drug, especially opioids or fentanyl, can cause an overdose. Old people, places and routines are suddenly back.
Vinsent Franke, our founder, knows this as a father. His son, Max, was in treatment and doing well, and he died of an overdose in the week he was due to graduate, after a roommate who had left two days earlier made a plan with him to use. Vinsent shares this so other families take the transition home as seriously as the treatment itself.
At iRely Recovery, aftercare planning starts during residential treatment, not on the last day.
What a strong discharge plan includes
- A step-down level of care (IOP or outpatient) booked before discharge
- A clear plan for the first 72 hours home
- Naloxone (Narcan) in the home if opioids were involved
- Agreed boundaries about contact with people who are still using
- Regular check-ins with the alumni community and a sponsor or recovery group
If Your Loved One Wants to Leave Early
Many people want to leave treatment in the first week or two, often when withdrawal and emotions peak. If your loved one calls asking you to pick them up:
01
Stay calm and listen
Hear them out without arguing.
02
Don’t agree to anything on that call
You can say you love them and will call back.
03
Call the clinical team
They can talk with your loved one and help them through the moment.
04
Remind them why they went
And that you’ll support them through the hard part.
Adults can choose to leave voluntary treatment. Your calm, steady response can make the difference.
Frequently Asked Questions
How long is rehab for drugs and alcohol?
Most residential rehab programs last 30, 60 or 90 days, often starting with 3 to 10 days of medical detox. Your clinical team sets the plan for each person and will walk you through it at admission. Many people continue with outpatient care afterward, since 90 days or more of total treatment tends to work best.
What happens in rehab?
Rehab usually starts with medical assessment and detox, followed by daily individual therapy, group therapy, family sessions, holistic activities and aftercare planning. Your clinical team sets the plan for each person and will walk you through it at admission.
Can you have your phone in rehab?
It depends on the program and stage of treatment. Your clinical team sets the communication plan for each person and will walk you through it at admission.
Can you visit someone in rehab?
Usually yes, once detox is complete and the clinical team agrees. Visits and family sessions are planned as part of the treatment plan. Ask the team about timing and what to bring.
What should I bring to rehab?
Photo ID, insurance card, medications in original bottles, 7 to 10 days of comfortable clothing, alcohol-free toiletries, and contact numbers on paper. Leave alcohol-containing products, weapons and valuables at home. Confirm the final list with admissions.
Will the treatment team update me on my loved one?
Only if your loved one signs a written consent to share information. Federal privacy rules (HIPAA and 42 CFR Part 2) protect addiction treatment records. Without consent, the team can still listen to you.
What if my loved one wants to leave rehab early?
Stay calm, don’t agree to pick them up on the first call, and contact the clinical team so they can talk with your loved one. Wanting to leave is common in the first two weeks and often passes with support.
What happens after rehab?
Most people step down to intensive outpatient or outpatient care and join an alumni or recovery community. The first weeks home carry the highest risk, so a written discharge plan made before leaving is essential.
If It’s an Emergency
If your loved one is unresponsive, having a seizure, struggling to breathe or may have overdosed, call 911 now. If they are talking about suicide, call or text 988. iRely Recovery is not an emergency service.
