Length of stay is one of the first things people want to understand before starting inpatient treatment. The answer is not the same for everyone. It depends on the substance involved, how severe the dependence is, whether mental health concerns are present, and how the person responds once treatment begins.
At a trusted rehab in Newfane, each person should be assessed before a timeline is set. Some clients may need a shorter detox period before moving into rehab, while others may need more time and support throughout care. The goal is to build the treatment plan around the person’s actual needs, not force everyone into the same schedule.
How Long Detox Typically Takes
Detox duration varies by substance. The timeline is driven by how the body processes each type of drug and how severe the dependence has become.
For opioid detox, acute withdrawal from short-acting opioids like heroin typically peaks within 48 to 72 hours and begins to resolve within 5 to 7 days. Longer-acting opioids can extend that timeline. With medication-assisted treatment using Suboxone or Buprenorphine, withdrawal symptoms are significantly reduced, which allows the process to proceed within that general timeframe more comfortably.
For alcohol detox, the acute withdrawal phase typically lasts 5 to 10 days, though it can extend in cases of severe dependence. The first 48 to 72 hours carry the highest risk for complications, including seizures and delirium tremens, which is why continuous medical supervision during this period is clinically necessary.
For benzodiazepine detox, the timeline is generally longer. Because stopping benzodiazepines abruptly carries serious medical risks, detox is managed through a gradual tapering protocol supervised by a physician. The tapering schedule is adjusted based on the specific benzodiazepine involved and the individual's clinical response throughout the process.
How Long Does the Residential Rehabilitation Program Last
The primary residential rehabilitation program at our facility is 28 days. This is a short-term residential program that provides structured daily treatment: individual counseling, group therapy, evidence-based therapeutic programming, medication management where applicable, and structured discharge planning.
The 28-day format reflects the clinical standard that a minimum of several weeks of structured residential treatment is needed to address the behavioral and psychological dimensions of addiction in a meaningful way. It allows enough time for the brain to begin stabilizing, for therapeutic work to gain real traction, and for discharge planning to be thoughtful rather than rushed.
Length of stay is individualized. Some clients complete treatment within the standard timeframe. Others stay longer based on clinical need and progress. The timeline is reviewed throughout the program and adjusted when the clinical picture calls for it.
What Factors Affect How Long Treatment Takes
Several clinical factors influence the overall length of an inpatient stay. Understanding them helps set realistic expectations before admission.
The type and severity of dependence are one of the primary drivers. A person with a long history of heavy alcohol use and prior withdrawal complications will have a different medical timeline than someone entering treatment at an earlier stage. The clinical team accounts for this from the first assessment.
Co-occurring mental health conditions also affect treatment length. When depression, PTSD, anxiety, or bipolar disorder is identified at the psychiatric evaluation conducted within the first 24 hours of admission, both the addiction and the mental health condition are addressed as part of the same treatment plan. Managing both conditions simultaneously is the right clinical approach, and it may require additional time to do so thoroughly.
Prior treatment history matters as well. Clients who have been through treatment before and relapsed may need additional time to identify and work through the specific patterns and triggers that contributed to that relapse. Individual counseling sessions are where that specific work happens and where progress is assessed throughout the program.
Detox and Rehab Are Not the Same Clock
One common point of confusion is worth addressing directly. Detox and rehabilitation are separate stages with separate timelines. When people ask how long inpatient treatment lasts, they are sometimes asking about detox alone, sometimes about rehab alone, and sometimes about the full continuum. The answer is different for each.
Detox is the medical process of clearing substances from the body. For most substances, the acute phase takes between 5 and 10 days with clinical supervision. Rehabilitation is a structured treatment program that follows detox. At our facility, it is a 28-day residential program.
A client who enters for both detox and residential rehab can expect a total stay that combines those two timelines. Because we are licensed to provide both services, a client moves from detox directly into the residential program without a transfer, a gap, or a change in clinical team.

What Happens After the 28-Day Program
Completing the residential program is a significant milestone, but it is not the end of the process. Discharge planning begins well before the final day of treatment and is built around each client's specific situation and ongoing needs.
Aftercare may include referrals to outpatient counseling or intensive outpatient programs, continued MAT prescriptions and management with a local physician, peer support group connections, and a written relapse prevention plan. The goal is a transition that is supported and structured, not a sudden shift from intensive daily care to no support at all.

Frequently Asked Questions
Is 28 days long enough to treat addiction? A 28-day program addresses the immediate clinical needs of withdrawal stabilization, behavioral and psychological treatment, and structured discharge planning. For many people, it is the necessary and effective first phase of a longer recovery process. Aftercare referrals and relapse prevention planning before discharge are specifically designed to continue the work that begins during the residential stay.
Can I leave inpatient rehab before the program is finished? Clients are adults who make their own decisions about their treatment. However, leaving before the program is complete significantly reduces the clinical benefit of admission.
The clinical team is available at any point during the stay to discuss concerns and adjust the treatment plan if specific circumstances make continuing difficult.
Does insurance cover the full length of treatment? Most Medicaid plans in New York cover inpatient substance use disorder treatment at OASAS-licensed facilities. Coverage for the full length of stay depends on the specific plan and ongoing clinical necessity. A dedicated staff member at our facility handles insurance verification and approval so clients and families do not manage that process alone. Visit our admissions page for details on the insurance verification process.
What is the difference between short-term and long-term residential rehab? Short-term residential programs, like our 28-day program, address the acute phase of addiction treatment. Long-term residential programs, which typically run 90 days or longer, are designed for clients who need extended support, have not succeeded in shorter programs, or have clinical needs that require a longer treatment period. The team at admission assesses which level of care is most appropriate for each person.
Do I have to complete detox before starting the rehab program? Not necessarily. Clients who have already completed detox at another facility can enter our residential program directly. For clients who need detox first, both stages are available at our facility with the same clinical team, so there is no transfer or handoff required.
