Is Barbiturates legal in Singapore?
- Legal status
- Barbiturates are prescription-controlled substances (barbituric acid and its derivatives) transposing the 1971 psychotropic schedules; they sit below the Misuse of Drugs Act narcotic tier and are regulated as controlled/poison-scheduled prescription medicines.
- Consequences if caught
- Unauthorised possession or supply of a prescription-controlled substance draws a fine and/or imprisonment. Singapore's death penalty (MDA Second Schedule) applies only to narcotics and amphetamine-type drugs above trafficking weights — barbiturates are not death-eligible.
- If prescribed or medical
- Phenobarbital is dispensed as a prescription antiepileptic (a WHO Essential Medicine); the sedative-hypnotic barbiturates are tightly controlled.
- Documentation
- Carry a prescription and keep the medicine in original packaging; declare controlled medicines on entry.
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.
