KET - Ketamine

UK Class B Illegal Drug

Ketamine is increasingly emerging as a substance of concern in the United Kingdom, both for its illicit recreational use and its growing application in medical treatment. Medically, ketamine may be prescribed by the NHS or licensed private practitioners, typically for treatment-resistant depression or severe pain management, and only under strict clinical protocols.

Although international research and shifting attitudes have led to some discussion around the potential for broader therapeutic use of ketamine, decriminalisation is not currently a mainstream political stance in the UK. Even if regulatory changes were to occur, ketamine would still be tightly monitored and subject to drug testing, much like alcohol, due to its dissociative effects and significant impact on cognitive and motor functions.
