1P-LSD in Malaysia: not individually verified

Not individually verified

We have not confirmed that 1P-LSD specifically is scheduled in Malaysia, 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 Malaysia, and the reason is stated rather than left open. 1P-LSD is named nowhere in the First Schedule to the Dangerous Drugs Act 1952, and the two questions about it pull opposite ways. Lysergide is named in Part III as «(+)-Lysergide, (+)-N-N-diethyllysergamide (d-lysergic acid diethylamide)», and Part III's generic clause reaches only «The isomers ... The esters and ethers ... The salts». 1P-LSD is an N1-propionyl amide of lysergide, which is none of those four, so on the Act's own words it is not a dangerous drug. But the Poisons List entry for the same substance reads «LSD or LSD-25 or (+)-N,N-diethyllysergamide or d-lysergic acid diethylamide; its derivatives», and it carries the «(DD)» marker the Poisons List uses to flag a dangerous drug. A derivative is exactly what 1P-LSD is. The Poisons List cannot enlarge the First Schedule, which only a section 45A order can do, so the better reading is that 1P-LSD is not a dangerous drug and carries no section 39B exposure. That reading is not settled, and since the whole question is whether this substance is capital or a four year offence, the status is not confirmed. Searched, on 2026-09-17: all five Parts of the First Schedule to the Dangerous Drugs Act 1952 as printed in the Attorney General's Chambers updated text at 4 July 2023, for the substance's name, its systematic name and its abbreviations; the section 37(da) and section 39A weight lists; the Poisons List and the Third Schedule of the Poisons Act 1952; and both section 45A orders since the consolidated text, P.U. (A) 97 of 2 April 2024 and P.U. (A) 416 of 25 November 2025. What came back is set out above. The status is not confirmed because the unresolved point is the capital one, and no Malaysian decision settling it was found.

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