Is 2-FDCK legal in United Kingdom?

Legal status

Class B controlled drug — 2-FDCK is not a named entry but is captured by the arylcyclohexylamine generic definition in the Misuse of Drugs Act 1971 (the same structural class as ketamine and methoxetamine), which places it in Class B; the Psychoactive Substances Act 2016 provides a blanket backstop. Mechanism: arylcyclohexylamine generic.

Consequences if caught

As a Class B drug, possession of 2-FDCK carries up to 5 years' imprisonment plus a fine, and production or supply up to 14 years plus a fine.

If prescribed or medical

No medicinal or prescription status — 2-FDCK has no marketing authorisation and, unlike ketamine (a licensed anaesthetic), the ketamine analogues caught by the generic are placed in Schedule 1 of the Misuse of Drugs Regulations as having no recognised medical use.

Documentation

Import, purchase and possession are offences; the ACMD's 2026 ketamine review confirmed that 2-FDCK and other analogues captured by the UK arylcyclohexylamine generic remain Class B. 2-FDCK is also a Schedule II psychotropic under the 1971 Convention (in force 3 December 2024).

Drug laws and enforcement change and vary within a country. This is not legal advice. Always confirm with United Kingdom’s embassy or official drug authority before traveling; penalties can be severe, including imprisonment.
