Is Mephedrone (4-MMC) legal in Singapore?
- Legal status
- Controlled — NAMED. Mephedrone is individually added to the First Schedule (Class A) of the Misuse of Drugs Act (Cap. 185) on 15 Nov 2010 (with BZP and TFMPP). It sits BELOW the capital tier: MDA mandatory-death trafficking applies only to substances with a Second Schedule capital quantity, and mephedrone carries no such threshold — no death-penalty exposure.
- Consequences if caught
- Class A: possession and trafficking offences carry imprisonment and caning, but mephedrone is not death-eligible (no Second Schedule capital quantity).
- If prescribed or medical
- Class A controlled drug with no recognised medical use and no lawful prescription route.
- Documentation
- No licit personal-carry or import route for a Class A drug.
Drug laws and enforcement change and vary within a country. This is not legal advice. Always confirm with Singapore’s embassy or official drug authority before traveling; penalties can be severe, including imprisonment.
