Is 3-MMC legal in United Kingdom?
- Legal status
- 3-MMC (3-methylmethcathinone) is a controlled Class B drug, caught by the ring-substituted cathinone generic definition in the Misuse of Drugs Act 1971 (Class B, eff. 16 Apr 2010) — the same 2010 generic that captured mephedrone reaches the 3-isomer, so the UK never needed a dedicated 3-MMC amendment; the Psychoactive Substances Act 2016 is a blanket backstop.
- Consequences if caught
- Class B: possession up to 5 years plus a fine; supply/production up to 14 years and an unlimited fine. Non-death-penalty jurisdiction.
- If prescribed or medical
- No recognised medical use and no lawful prescription route; 3-MMC is a controlled NPS, not a licensed medicine.
- Documentation
- No lawful personal-import route for a controlled Class B substance; carrying it through UK customs is an offence.
