Is 3-MMC legal in Malaysia?

Confirmed against a primary sourceVerified July 14, 2026
Legal status
3-MMC (3-methylmethcathinone) is controlled, caught by the cathinones added to the First Schedule of the Dangerous Drugs Act 1952 and by Malaysia's 1971 Convention obligation; the exact 3-MMC-specific entry is left to confirmation.
Consequences if caught
DDA offences carry heavy imprisonment and caning, but 3-MMC is BELOW the capital tier: the s.39B mandatory-death list is drug-specific (heroin, morphine, monoacetylmorphine, cocaine, methamphetamine quantities) and cathinones/3-MMC are not among the s.39B capital drugs.
If prescribed or medical
No recognised medical use and no lawful prescription route.
Documentation
No lawful personal-import route for a controlled dangerous drug.
