Ketamine doesn’t behave like the drugs it tends to get grouped with. It isn’t a stimulant and it isn’t a depressant. Ketamine addiction treatment therefore differs from the templates built around drugs like cocaine or heroin.
It’s also part of why ketamine addiction tends to be the one that takes the longest to identify. It comes in around the edges of a social life, and its harms show up in places people don’t always think to check – the bladder, our memory, or the narrowing of what feels manageable in a day.
Castle Health is a private treatment provider with clinics across Europe, including Castle Craig in Scotland and Smarmore Castle in Ireland. We offer medically supervised detox, residential and outpatient programmes, and therapy grounded in the 12 Step approach.

Why ketamine addiction treatment needs a different approach
Ketamine is a dissociative anaesthetic. It isn’t a stimulant like cocaine, and it isn’t a depressant like alcohol or heroin. Withdrawal from ketamine is mainly psychological and urological. It isn’t the acute physical syndrome people often expect from detox. Here, cravings, low mood, anxiety and disturbed sleep tend to dominate.
Many people who develop ketamine addiction are seeking the dissociative effect, and that becomes learned over time. Treatment has to address dissociation as a learned response, not just a chemical effect that passes when the drug leaves the body.
Research from the University of Exeter found that nearly half of people with ketamine addiction were not seeking help. 59% said awareness of the risks was lacking. One participant described ketamine addiction as becoming “even stronger than being addicted to heroin or cocaine”. That’s the gap the right ketamine addiction treatment has to close.
Ketamine-specific physical risks, including bladder damage
Long-term, frequent ketamine use is associated with memory problems, depression, and anxiety. At high doses, frequent ketamine may cause psychosis, a mental health condition that results in losing touch with reality, and delusions that can last up to one month after a person stops.
More than half of users have been reported to experience K-cramps – the abdominal cramping linked to heavy ketamine use. The cramps often drive people back to the drug to ease pain the drug caused in the first place.
Heavy ketamine use can also cause ketamine-induced cystitis, a painful inflammation of the bladder wall. The same research found that 60% of people studied had experienced ketamine bladder symptoms or nasal problems. Ketamine-induced cystitis can become irreversible without intervention. In the most serious cases, treatment can involve bladder removal and a urostomy bag.
Medically supervised detox for ketamine addiction
Medication may be used to manage specific symptoms, such as sleep, anxiety or pain related to bladder symptoms. Howwever, the evidence base available for pharmacological treatment in ketamine use disorder is limited and of low quality. Even so, detox for ketamine addiction looks different from detox for alcohol or other drugs:
- The psychological symptoms tend to dominate – cravings in particular, and the disrupted sleep that follows.
- There is no equivalent of an acute alcohol withdrawal syndrome, but it is psychologically intense. This is where 24/7 support helps to ensure people don’t return to using the drug in this period.
Inpatient and outpatient ketamine addiction treatment
Inpatient, residential rehab treatment for ketamine addiction is a programme based at one of our clinics in either Scotland, or Ireland. Inpatient treatment gives you distance from the triggers around use and round-the-clock clinical support during detox and early recovery. It tends to suit:
- People whose use is severe
- Those whose home environment isn’t stable,
- Those who’ve tried treatment before that didn’t hold, or
- People who are managing other mental health concerns alongside ketamine addiction.
Outpatient ketamine addiction treatment is designed to fit around work and week-to-week life. Outpatient treatment gives you the structure and clinical input of a rehab programme without the residential stay. Residential treatment is still there if the picture changes.
It tends to suit:
- People with a more stable home environment
- Those with less severe dependence, or
- Those stepping down from a residential programme.
Therapies for ketamine addiction
Therapy for ketamine addiction does two things – It works on the use itself, and the dissociation pattern underneath it. Cognitive Behavioural Therapy (CBT) for ketamine addiction helps you notice the thoughts and situations that send you towards ketamine, and gives you ways to respond differently. Dialectical Behaviour Therapy (DBT) adds skills for managing the strong feelings that dissociation has been doing the work of avoiding.
Both sit inside our wider 12 Step programme, with group therapy and family therapy alongside. The 12 Step framework is what we use, and the cognitive and behavioural work is how we get there.
“I contacted Castle Health seeking guidance and options to support a relative who was having a difficult time with addiction and other mental health concerns. The team were incredibly kind and informed. They took the time to go through all the options with me and helped us plan how to approach the matter. The person has now been receiving care for several months and is doing really well. A big thank you to the wonderful team.”

What to expect from ketamine addiction treatment with Castle Health
Our approach to ketamine addiction treatment puts the person before the diagnosis. We start with a full picture of what’s happening for you, then build a plan around that. The 12 Step framework gives the structure, the clinical team gives the rigour, and the rest is shaped to fit:
- When you first get in touch, we offer a free confidential assessment with a treatment specialist. Here, we’ll ask about your use, your circumstances, your physical health (including bladder symptoms if relevant) and what you might want to achieve from treatment.
- From there we’ll talk through whether inpatient or outpatient fits, if one of our other clinics might be a better match for you geographically, and what the next step looks like.
Admissions can move quickly if needed, particularly where physical risk is involved. We’ll walk you through the process at your own pace.
Recovery from ketamine addiction is sustained over time rather than completed on discharge, and our aftercare keeps you connected to the team and the wider recovery community once the programme ends.
If someone you know needs help with ketamine addiction
If you’re the partner, parent or friend of someone with ketamine addiction, you’ve probably been holding more than you might realise. Sometimes for months. Sometimes for years. The worry sits underneath everything, and the things you’ve tried haven’t held the way you hoped they would.
You might have noticed the bladder pain or the trips to A&E. The cognitive changes, the memory slips, the time spent away from people who used to be central. The drop in work or study. The shift in mood.
Ketamine addiction is treatable, and the people we work with do recover.
Starting a conversation about ketamine addiction with the person in your life is rarely easy. The short version is to lead with what you’ve noticed and what you’re worried about, rather than what they should do.
Family therapy is part of what we offer at Castle Health, because addiction affects the whole household and recovery tends to hold better when the household is involved. Where direct conversation hasn’t worked, a structured intervention can be the right next step, and we can talk you through how that works.

Frequently asked questions about ketamine addiction treatment
How long does ketamine stay in your system?
In urine, ketamine is typically detectable for two to four days after use. In blood, the window is shorter, usually around 24 hours. Hair tests can detect ketamine for up to 90 days. If you’re worried about your own use, a free confidential assessment is a better starting point than a test.
Is ketamine addiction treatable on the NHS?
Yes. NHS pathways for ketamine addiction exist through community drug and alcohol services and stepped care, and NHS guidance on getting help with drug addiction sets out how to access them. Waiting times and the level of service vary by region. Private treatment tends to offer faster access, residential options, and a programme tailored to ketamine specifically rather than substance use in general. Both routes work. The right choice depends on what you need and when you need it.
Can I keep working during ketamine addiction treatment?
Outpatient ketamine addiction treatment is designed to fit around work and the rest of your week. Sessions can be arranged around your schedule and you continue living at home. Residential treatment generally means time away, usually 28 days, sometimes longer. Whether and how you disclose to an employer is your choice, and many people structure annual leave or sick leave around treatment without going into specifics. Our admissions team can talk you through what’s practical for your situation.
