Is 1P-LSD legal in Brunei?

Confirmed against a primary sourceVerified September 20, 2026
Legal status
Class of this substance is unsettled on the face of the Act. It is neither named nor plainly outside the nearest entry, "Lysergide and other N-alkyl derivatives of lysergamide" in Part I of the First Schedule to the Misuse of Drugs Act, Chapter 27 of the Laws of Brunei Darussalam, Revised Edition 2013 (B.L.R.O. 2/2013). The 1-propionyl group is an acyl substituent, not an alkyl one, so the words of the entry do not plainly reach it.
Consequences if caught
Everything below turns on whether 1P-LSD falls inside "Lysergide and other N-alkyl derivatives of lysergamide". The 1-propionyl group is an acyl substituent, not an alkyl one, so the words of the entry do not plainly reach it. If it does, the Class A penalties apply and they are these. Trafficking under section 3 carries a maximum of 20 years and 15 strokes with a minimum of 5 years and 5 strokes. Possession for the purpose of trafficking under section 3A carries the same. Manufacture under section 4 carries a maximum of 30 years and 15 strokes with a minimum of 10 years and 5 strokes. Import or export under section 5 carries a maximum of 30 years and 15 strokes with a minimum of 5 years and 5 strokes. Simple possession under section 6(a) carries a maximum of 10 years, a fine of 20,000 Brunei dollars or both, rising to a minimum of 2 years on a second or subsequent conviction. Consumption under section 6(b) carries the same maximum with a minimum of 3 years on a second or subsequent conviction. Section 29(3) doubles the punishment for a second or subsequent offence under Part II other than section 6. If it does not, no offence under this Act arises at all, because the Part II offences reach only a controlled drug, and the Act supplies no analogue or resemblance clause that would close the gap either way. Capital and life exposure. Death is not available on either reading. If the substance is inside the entry it is a Class A drug, and no Class A column entry anywhere in the Second Schedule is death; it is named in no row of the specified drug column, which is the only column in which death appears and which names just opium, morphine, diamorphine, cocaine, cannabis, cannabis resin, methylamphetamine and MDMA. If it is outside the entry, no penalty under this Act arises at all. The listing question therefore changes the term of imprisonment and never the availability of death. Where death does appear it is mandatory. Section 29(2) provides that the columns "show respectively the punishments to be imposed on a person convicted of the offence", and each death row gives death alone with no maximum, no minimum and no alternative. No provision of the Act confers a sentencing discretion on a capital conviction. The Act creates no sentence of life imprisonment. The phrase appears nowhere in its text, and the longest determinate term it reaches is 30 years. On the direction of error: this cell presents the Second Schedule as reaching the substance, which overstates exposure if the defects described above are read literally rather than purposively. Overstatement is the safer direction for a reader deciding what to risk.
If prescribed or medical
For 1P-LSD this follows the listing question and cannot be settled ahead of it. On the reading that brings it inside the entry, it sits in the Fourth Schedule to the Misuse of Drugs Regulations, Chapter 27, Rg 1, which attaches regulations 14(1), 15 and 28(1). There is no ordinary dispensing route. Lawful handling runs through a licence issued by the Minister under regulation 4, or through regulation 5. Regulation 11 requires the prescription to be indelible, signed and dated, with the dose and the total quantity written in both words and figures in the prescriber's own hand, and the name and address of both patient and prescriber. On the reading that leaves it outside, the Regulations do not govern it at all, because they operate only on controlled drugs. What was not checked for this cell is Brunei's medicines and poisons regime, which is a separate body of law that was not fetched. Absence from the Misuse of Drugs Act is not a statement that a substance is freely available.
Documentation
Because the listing question for 1P-LSD is open, the prudent course is to carry the documents that would be required if it is inside "Lysergide and other N-alkyl derivatives of lysergamide": a regulation 11 prescription in the prescriber's own hand, and the product in its labelled dispensed container. Import and export are their own offence under section 5 and carry heavier minimums than trafficking, so carrying a supply into Brunei is the graver charge, not the lesser one. A person who assumes 1P-LSD is outside the Schedule is betting on a reading of the Act that no Brunei court has been shown to have adopted.
Primary sources
  • Misuse of Drugs Act, Chapter 27 of the Laws of Brunei Darussalam, Revised Edition 2013 (B.L.R.O. 2/2013). The list of controlled drugs sits in the First Schedule to the Act, not in subsidiary legislation, and the empowering section is section 35: "His Majesty the Sultan and Yang Di-Pertuan in Council may, by order published in the Gazette, amend the First and Third Schedules". That power reaches the First and Third Schedules only, so the capital thresholds in the Second Schedule cannot be changed by order. The schedules were last amended by S 12/2012 and consolidated into this Revised Edition
  • the publisher's own page for Chapter 27 lists five amendment orders ending there, and every later gazette notification under the Act concerns approved institutions and appointments rather than any schedule. This cell was read from the nearest entry, which the substance neither plainly satisfies nor plainly escapes. The entry relied on is at line 1637 of the plain text extraction of the official PDF. Read from the Attorney General's Chambers copy at https://www.agc.gov.bn/brulaw/misuse-of-drugs-act/ together with the Misuse of Drugs Regulations, Chapter 27, Rg 1. For 1P-LSD the reading turned on the entry "Lysergide and other N-alkyl derivatives of lysergamide".
