Ketamine Therapy for Alcohol Use Disorder: Beyond the Psychedelic Experience
Recent research is challenging the conventional wisdom surrounding ketamine-assisted psychotherapy for alcohol use disorder. For years, the theory posited that ketamine’s therapeutic effects stemmed from its powerful psychedelic properties. However, a new study from King’s College London and the University of Exeter, published in Addiction, suggests the story is far more complex.
The Shifting Understanding of Ketamine’s Impact
The study, based on data from the Ketamine for reduction of Alcoholic Relapse (KARE) clinical trial, found that the intensity of psychedelic effects – altered reality, dissociation, warped time perception – experienced during intravenous ketamine infusions did not predict the success of treatment. Participants reported significant psychoactive experiences, consistently strong across three weekly infusions, yet these experiences didn’t correlate with increased abstinence from alcohol over a six-month period.
This finding is significant given that it directs researchers to explore other mechanisms at play. Dr. Will Lawn, Senior Lecturer at the Institute of Psychiatry, Psychology & Neuroscience at King’s, noted that while ketamine shows promise in helping people remain sober, the benefits may not be directly tied to the psychedelic experience itself.
What Could Be Driving Ketamine’s Therapeutic Effects?
If not the psychedelic effects, what is responsible for ketamine’s potential to aid recovery from alcohol use disorder? Researchers are now focusing on the possibility that changes in brain connectivity and function are key. Professor Celia Morgan from the University of Exeter emphasizes the need to refine dosing strategies to maximize effectiveness. “We still don’t know the clinical reason why these experiences promote abstinence,” she stated.
Alcohol use disorder remains a substantial public health issue, with over 85,000 people in England receiving treatment annually. The search for more effective treatments is ongoing, and ketamine represents a potentially valuable addition to the existing toolkit.
The Future of Ketamine-Assisted Therapy: The MORE-KARE Trial
Building on the KARE trial, Professor Morgan is now leading a larger clinical trial called MORE-KARE, currently recruiting participants across the UK. This trial, funded by the NHS and Solvonis Therapeutics, aims to provide more definitive answers about how ketamine works and how to optimize its use in treating alcohol use disorder. The MORE-KARE study can be found at https://sites.exeter.ac.uk/morekare/.
The focus of MORE-KARE will likely involve detailed brain imaging and analysis to identify specific neural changes associated with successful treatment outcomes. This could lead to personalized treatment approaches, tailoring ketamine dosages and therapy protocols to individual patient needs.
Beyond Alcohol: Ketamine’s Potential in Addiction Treatment
The implications of this research extend beyond alcohol use disorder. The broader field of psychedelic-assisted therapy is gaining traction in the treatment of various addictions. Understanding the mechanisms behind ketamine’s effects could inform the development of therapies for other substance use disorders, as highlighted in research from the UK Parliament regarding addiction treatment.

FAQ
Q: Does ketamine therapy operate for everyone with alcohol use disorder?
A: Not necessarily. Research is ongoing to identify who is most likely to benefit from this treatment.
Q: What are the potential side effects of ketamine therapy?
A: Ketamine can cause a range of side effects, including altered perception, dissociation, and changes in blood pressure. These are typically managed under medical supervision.
Q: Is ketamine therapy a cure for alcohol use disorder?
A: No, it is not a cure, but it may be a valuable tool in helping people achieve and maintain sobriety.
Pro Tip: If you or someone you know is struggling with alcohol use disorder, reach out to a healthcare professional for support, and guidance.
