Rehab is a vital step for anyone struggling with addiction, but one of the most common questions is: how long does it take? The answer isn’t the same for everyone. Rehab length needs to be measured by critical metrics to keep recovery safe and give you the best footing for a sober future.
We’re laying out guidelines of how long rehab should be and the factors that influence duration, so you can set realistic expectations for your own recovery journey.
How long are typical rehab programmes?
Generally speaking, the dates and schedule of rehab programmes are not set in stone. A measured and considerate approach is paramount for the highest chances of successful recovery.
Detoxification is usually the starting point of rehab, helping the person manage the difficult and sometimes painful symptoms of withdrawal. Medical detox can last anywhere from a few days to a couple of weeks, with the average length being around 7 days (depending on the substance in question). However, detox on its own is rarely adequate for sustained recovery. It usually acts as the first step in a treatment plan that includes therapy, relapse prevention and aftercare.
Rehab length varies from centre to centre, and factors like the addiction severity, healthcare needs and outside commitments all have an influence. Some of the average lengths used in treatment are:
- Short-term detox or stabilisation programmes (around 7 days)
- 30-day rehab programmes
- 60-day rehab programmes
- 90-day rehab programmes
- Extended treatment options, such as 6-month, 1-year, or even 2-year programmes
- Transitional or extended-stay options like sober living residences
The best programme length is carefully tailored for safe withdrawal and to put you in the best stead for complete recovery.
What factors affect the duration of rehab treatment?
Two people’s journeys in rehab will never be identical, which is why the duration of treatment is tailored rather than fixed. Several key factors are at play when a specialist determines the rehab length, as well as whether inpatient or outpatient treatment is optimal. These factors include:
Addiction severity and history
The longer and more severe the substance use, the greater the need for extended support. Someone with years of entrenched patterns may benefit from a longer programme compared with someone seeking early intervention. A person’s relapse history also plays a role, as repeated attempts at recovery may mean a longer addiction recovery timeline is needed.
Co-occurring mental health conditions
Many people struggling with addiction sadly also suffer from mental health conditions like depression, anxiety, PTSD and other psychological ailments. Extensive research shows that around half of all people who have a substance use disorder will also experience a mental illness during their lives. This can force someone into needing dual-diagnosis care, in which both problems are addressed at the same time. Treating only one can be like trying to extinguish only half of a burning fire, increasing risks in treatment and the likelihood of relapse.
Your commitments in the outside world
We must also be realistic when considering the length of a person’s rehab treatment. Very few of us can completely break away from any and all commitments to the outside world. For most people, some external commitment needs to be factored in, like family, financial responsibilities or work holidays. Programmes are designed with flexibility in mind, balancing the clinical need for treatment with the reality of life outside rehab.
What are the benefits of longer rehab?
Healthcare professionals understand that shorter rehab programmes can be vital for stabilisation and taking the first steps into sobriety. However, the likelihood of relapse is often greater when only part of a problem is addressed. Longer stays bring deeper healing and a stronger foundation for coping mechanisms when urges develop, especially after long-standing addictions.
Each stage of extended treatment offers its own advantages, which include:
What happens to me after rehab?
Rehab is not the end of addiction recovery. It does not represent the back cover of a book, rather, it stands as a pivotal chapter in your lifelong story. You are now stepping into writing your own future, with your dark past set behind you.
Coming to terms with the end of rehab treatment and returning to your life sober will have its challenges. In fact, many addiction experts pay great attention to the importance of “People, places and things” in the early periods after rehab has ended. The phrase appears simple on the surface, yet it captures the reality that relapse risks are often tied to a spectrum of triggers, or external stimuli.
The mind has an incredible skill of connecting or linking these stimuli to drug or alcohol use. Triggers can range from the smell of a room you used to take drugs in, to the tinkling of two glasses chiming together.
Making a clean break and sustaining your sobriety doesn’t mean cutting every connection, but it does mean rethinking your surroundings with care. Following the principles of “people, places and things,” it may be beneficial to limit contact with people you used to take a substance with, or pay special attention to certain times of the day you used to spend taking drugs.
The weeks and months after rehab are as much about developing your new life as they are about leaving the old one behind. With small, proactive steps and the support of aftercare, you can fill the void left behind and step into your new, sober life.
Where can I find support for my addiction?
If you’re wondering about rehab length or what an addiction recovery timeline might look like for you, remember there’s no “one-size-fits-all.” The right programme is the one that meets your needs and gives you the time and space to heal.
