Is Phenibut legal in United Kingdom?
- Legal status
- Phenibut is caught by the blanket Psychoactive Substances Act 2016: as a psychoactive substance with no UK medicines licence and outside the Act's exempted categories, its production, supply, offer to supply and importation are prohibited (mechanism: blanket-NPS, not individually named); it is not scheduled under the Misuse of Drugs Act 1971.
- Consequences if caught
- Producing, supplying, offering to supply or importing phenibut is an offence under the 2016 Act; simple possession for personal use is not an offence except in a custodial institution, which leaves a grey area around personal use.
- If prescribed or medical
- Phenibut is not licensed as a medicine in the UK and has no prescription or medicinal status.
- Documentation
- Because import and supply are banned, lawful purchase of phenibut is difficult; sellers sometimes exploit the Act's food/supplement gaps, but importing it falls within the supply/import prohibition, and personal-use possession outcomes are left to confirmation.
