GBL in Singapore: not individually verified

Also known as: blue nitro

We have not confirmed that GBL specifically is scheduled in Singapore, so this page gives no legal status. Publishing a guess here would be worse than publishing nothing. What we do know is the governing national drug law, below.

What is on record

Not confirmed for Singapore. Gamma-butyrolactone is named nowhere in the Misuse of Drugs Act 1973, including the Third Schedule list of substances useful for manufacturing controlled drugs. Gamma hydroxybutyric acid is Class A at First Schedule, Part 1, paragraph 1, entry (64), "Gamma hydroxybutyric acid", and section 2 reaches "anything that contains any such substance or product"; whether a given GBL product is caught by that is a question about the material that the text does not answer. Otherwise GBL falls to Part 2A, the psychoactive substance offences. Section 2 defines a psychoactive substance as one "that has the capacity to have a psychoactive effect on an individual" and provides that it "does not include an excluded substance", the excluded substances being those in the Fifth Schedule. GBL is not in the Poisons Act 1938 list and not on the INCB Green List or Yellow List, so Fifth Schedule items 11 and 14 do not exclude it. Item 8 excludes "Any industrial material or substance", defined by reference to lists in the Fire Safety (Petroleum and Flammable Materials) Regulations, the Environmental Protection and Management Act 1999 and the Workplace Safety and Health (General Provisions) Regulations, none of which was read.

Confirm directly with Singapore’s national drug authority or your own embassy before you rely on anything.
