The need for ketamine addiction treatment has been growing rapidly in recent years. Ketamine is now one of the most used drugs in Britain, and there are even NHS clinics opening specifically for the damage ketamine causes.
Ketamine dependency can develop surprisingly quickly. By the time challenges around cutting down its use start to show, stopping without help can feel impossible.
Castle Craig is registered as a private psychiatric hospital in Scotland. We provide residential ketamine addiction treatment and operate at the highest level of medically managed inpatient care.
Our approach to ketamine addiction rehab recognises that every aspect of dependency needs to be addressed together. We provide ketamine detox and therapy as two parts of the same programme with continuing care extending after residential treatment ends.

Ketamine addiction — understanding your treatment options
-
What is ketamine addiction?
Ketamine addiction is the compulsive use of ketamine despite the harm it’s causing. In the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), it’s classified as ketamine use disorder.
Addiction to ketamine begins with the way the drug affects the brain’s reward system. With regular use, tolerance builds and you need more to feel the same effect. As that process continues, the body and mind can become dependent on the drug.
According to the Transform Drug Policy Foundation, ketamine has moved into mainstream UK drug culture over the past two decades. A growing number of people have developed more serious dependencies during that period.
A 2025 review by the Advisory Council on the Misuse of Drugs found that between 5-8% of ketamine users develop more problematic patterns of use. For these people, high doses taken daily become the norm – driven by increasing tolerance and withdrawal.

How ketamine addiction affects your health
Sustained ketamine use can cause potentially lasting harm to the body and mind.
The most well-documented physical consequence is ketamine bladder syndrome. According to the British Association of Urological Surgeons, approximately three in ten people who use ketamine develop bladder symptoms. These range from pain and frequent urination to, in severe cases, bladder contraction requiring surgery. The damage can be permanent, but the sooner someone stops, the better their chances of recovery.
Research published in Psychopharmacology found impairments in working memory, episodic memory, and executive function among heavy users. Some of these deficits persisted even after stopping.
Research published in Addiction found that high-dose use can trigger psychosis, and that delusional thinking can persist for up to a month after someone stops.
None of these are inevitable, but all become harder to reverse the longer ketamine use continues.

Why residential treatment works for ketamine addiction
Residential treatment removes you from the environments and routines associated with using. It provides round-the-clock medical supervision. This is particularly important when withdrawal brings difficult symptoms such as anxiety or low mood.
A retrospective study found that people in inpatient treatment for substance use disorders are three times more likely to complete it than those treated in the community. Clinical reviews of inpatient versus community-based care reach similar conclusions.
At Castle Craig, we believe ketamine addiction rehab to work best when detox and therapy are delivered by the same team. This reduces the risk of relapse and means you don’t need to build trust with new people at different stages of treatment.

Therapies used in ketamine addiction treatment
Our ketamine rehab therapy programme brings together a range of approaches. It begins as soon as you’re through the most challenging part of drug detox and feel ready to take part.
- Cognitive Behavioural Therapy (CBT) helps you examine the thinking patterns that have kept you using ketamine. It’s one of the most well-researched approaches in addiction treatment, and it gives you practical tools to take into daily life.
- Dialectical Behaviour Therapy (DBT) is useful when emotions have become too intense to manage. It gives you other ways to cope when things feel overwhelming.
- Group therapy might feel daunting at first, but for most people, it becomes one of the most useful parts of the programme. Hearing someone else describe exactly what you’ve been through can be more powerful than any one-to-one session. It tells you that what you experienced was real, and that you’re not the only one.
- There is also trauma therapy, family therapy, and 12 Step facilitation avaiilable, to help with specific personal needs and to prepare you for life after residential treatment.
We also incorporate complementary therapies such as equine therapy and mindfulness into the programme.
“I came to Castle Craig not really knowing if anything could change for me, and I’m leaving with a sense of hope I hadn’t felt in a long time. I’ll always be grateful to the staff and the place itself for giving me the chance to find my way back to myself and build a better me.”

The ketamine addiction treatment programme
Treatment at Castle Craig begins when you arrive at Kirkurd House, our dedicated admissions unit. Our clinical team carries out a full assessment and puts your individual treatment plan together.
The Foundation Programme runs for six weeks and forms the core of what we offer. It combines medically managed detox with the full therapy programme.
For people who need more time, including those with a dual diagnosis or a longer history of use, the Advanced Programme offers an extended residential stay.
When you leave Castle Craig, we stay involved to help you with the transition and adjustment period. Recovery isn’t always a straight line, and our continuing care is there for the moments when you need extra support.
Continuing care is planned as part of the programme from the start, and we offer two years of free aftercare to all our patients. You can read more about our approach and outcomes on our treatment success rates page.

Ketamine addiction and co-occurring mental health conditions
It’s common for people seeking help for ketamine addiction to also be living with existing depression, anxiety, or the effects of past trauma. In most cases, these are all part of the same picture, and treating them together tends to produce better outcomes.
Ketamine can also contribute to existing or new mental health conditions. Research published in Addiction found that psychosis and persistent delusional thinking can develop with heavy, long-term use, sometimes lasting for weeks after someone stops using.
At Castle Craig, every patient receives a full psychiatric assessment from a consultant on admission. We treat co-occurring mental health conditions as part of the same programme.
If cost is a consideration, treatment at Castle Craig is covered by a number of private health insurers. More information is available on our private health insurance cover page.

Can ketamine bladder damage be reversed after stopping use?
Stopping ketamine use early can lead to real improvement in bladder symptoms. The British Association of Urological Surgeons advises that stopping is the single best step you can take for your bladder, and that recovery of function is possible, particularly when use stops early.
In more advanced cases, some damage may be irreversible. The sooner someone stops using, the better their chances of recovery.
