How Long Does Drug Rehab Take?

One of the first questions people ask when considering treatment for drug use is, “How long will rehab actually take?” It’s a fair thing to wonder, especially when life outside doesn’t just pause because you’ve decided to get help.

The truth is, there’s no single answer. Rehab isn’t a one-size-fits-all programme. The time someone spends in treatment depends on a few key things: what substances they’ve been using, how long they’ve been struggling, their mental and physical health, and how ready they feel to make changes that stick.

Short-Term Rehab (7 to 28 Days)

Some people start with short-term rehab. This is usually between one and four weeks and often focuses on detox and initial recovery. It’s most useful for those who need help getting through the first intense phase of stopping drugs; especially when withdrawal symptoms are dangerous or distressing.

For example, someone who’s been using ketamine daily for a long period might find the physical effects quite severe at first: including bladder issues, confusion, or deep emotional numbness. Short-term rehab offers a safer environment to manage that stage, especially with medical support available.

But it’s important to know that short stays are just the beginning for many. Detox might clear the drugs from your system, but it doesn’t fix the reasons they were there in the first place.

Medium-Term Rehab (30 to 60 Days)

This is where the real work tends to happen. Once withdrawal is under control, the focus shifts to the mental and emotional side of recovery. That means therapy – one-to-one and group – and starting to understand what led to the drug use in the first place.

A stay of around one or two months gives time to:

  • Get physically stronger and sleep more normally
  • Start building coping skills that don’t involve substances
  • Open up about difficult experiences that might be connected to using
  • Try new ways of managing stress or painful emotions

There’s usually a routine involved, which can feel strange at first, especially if your life has been chaotic. But for many, this structure becomes something to hold onto when everything else feels shaky.

Long-Term Rehab (90 Days or More)

Longer rehab programmes are often recommended for people with deep-rooted addictions, mental health struggles, or repeated relapses. It’s not about being “worse” than anyone else. It’s simply about giving recovery the time it needs to stick.

When someone’s been using for years, or has turned to substances like heroin, crack, or heavy ketamine use to cope with long-term trauma, a few weeks often isn’t enough. It can take months just to feel emotions properly again, let alone figure out how to live without drugs as the main way of coping.

In long-term rehab, there’s more time to work on:

  • Building trust in yourself and others
  • Repairing damaged relationships if that’s something you want
  • Thinking clearly and making better decisions
  • Finding small moments of joy in everyday things again

Recovery isn’t quick. But it’s possible with time, space, and support.

Does Longer Mean Better?

Not always. The goal isn’t to “do your time” and walk out perfectly healed. Some people find big changes in a few weeks, others need more time. What matters more is what you actually need, not what the calendar says.

Some people use short-term rehab as a stepping stone, then continue recovery through outpatient therapy, support groups, or sober housing. Others find that staying longer gives them a better shot at avoiding relapse, because they’ve had more time to build confidence and stability.

Recovery Doesn’t End at the Door

Whether you’ve been in rehab for a week or six months, the end of your stay is really just the start of life in recovery. That means making choices every day to stay on track and having people or routines that help you stick with it.

Some people line up aftercare like:

  • Weekly counselling
  • Local support groups (like NA or SMART Recovery)
  • Check-ins with their rehab centre or sponsor
  • Living in a sober house to ease the shift back to daily life

Time in rehab matters. But what happens after is just as important.

So, How Long Will You Need?

That depends on your situation, your goals, and how things feel once you’re inside. If you’re not sure, you don’t need to have all the answers straight away. Talking to a professional can help you figure out what makes the most sense, without pressure.

And remember: asking the question at all is a good sign. It means you’re thinking about something different for yourself; something healthier, safer, and more honest. Recovery doesn’t work on a timer, it works when you give it a real chance.
