Drug Offences

Singapore drug offence guides — possession, consumption and trafficking under the Misuse of Drugs Act, with penalties, presumptions and defences.

Drug offences are among the most heavily regulated areas of Singapore criminal law, covering conduct from possession and consumption to trafficking under the Misuse of Drugs Act. The way a case is treated depends closely on the type of drug, the quantity involved, and the exact charge.

The guides here explain how these offences are framed, the concepts that often arise — such as statutory presumptions — the defences that may be available, and what the process looks like from arrest onward. Because the stakes in drug cases can be very high, early legal advice is essential. If you or someone close to you is under investigation for a drug matter, speak to a criminal lawyer before giving any statement.
