Treatment Outcomes
There is a strong evidence base to support the treatment methods used at Castle Craig and in support of residential rehabilitation treatment for addiction
Castle Craig has not only academic and theoretical backing for its treatment programme, but it also has mounting evidence for its own outcomes. Very few treatment services can show this depth of support for their methods.
Outcomes From a Cohort of Patients at Castle Craig Hospital, 2015*
- 73.4% out of 158 respondents were totally abstinent from all drugs or alcohol at follow-up (after one year).
- 91.8% of those who responded were either living with reduced alcohol or drug use or abstinent.
- 81.6% of respondents were classed as a “good outcome” by the independent reviewers.
- Our treatment is very successful. It is evidence-based, and the evidence is independently verified.

A successful treatment programme for addictive disease needs structure because so often in the lives of our patients there is no structure. The drug dictates how they live their life.

What Makes Our Treatment Successful?

Articles & Industry Studies
Castle Craig works with many of the UK’s leading voices on the subject of alcohol, drugs and addiction. In addition to following the latest developments and research in our sector, we attend and present at addiction treatment conferences around the world and commission our own research. Because of our high reputation, the media often seeks out staff opinions and contributions.
“There is a vast body of evidence to show that residential treatment for addictions can enable people to lead drug-free lives.” – Professor Jonathan Chick.

How Can Castle Craig Help?
Who will I speak to when I call Castle Craig?
When you call you will reach our Help Centre team who will give you all the information you need to help you decide whether to choose treatment at Castle Craig. If you decide that you would like to have a free screening assessment you will be asked a series of questions to build up a picture of your medical and drug use history as well as any mental health issues you are facing. If you decide you want to proceed with treatment you will be put in touch with our admissions case managers who will guide you through the admissions process.
How long is the rehab programme?
Residential rehab treatment starts at 4 weeks and can go up to 12+ weeks. Research shows us that the longer you stay in rehab and are part of the residential therapy programme, the longer the likelihood of continued abstinence and stable recovery.
How do I pay for rehab?
One concern we sometimes hear from people is how they will fund their rehab treatment. You can pay for treatment at Castle Craig privately, or through medical insurance, and some people receive funding through the NHS. The cost of rehab varies depending on what kind of accommodation you choose.
What happens at the end of my treatment?
Castle Craig thoroughly prepares patients before departure by creating a personalised continuing care plan which is formulated following discussions with the medical and therapeutic team. We offer an online aftercare programme which runs for 24 weeks after leaving treatment, in order to ensure a smooth transition back into your everyday life. Patients leaving treatment automatically join our Recovery Club where they can stay connected via our annual reunion, events, online workshops and recovery newsletters.
