Is HHC legal in Malaysia?

Legal status

Hexahydrocannabinol is named nowhere in the First Schedule to the Dangerous Drugs Act 1952 and nowhere in the Poisons Act 1952. Part III names delta-8-THC, delta-9-THC, their hydroxy forms, Parahexyl and «Tetrahydrocannabinols» under a specific chemical designation, and HHC is not a tetrahydrocannabinol: it is the hydrogenated form, with no double bond in the ring. It is not an isomer of THC either, since hydrogenation changes the molecular formula, so the Part III generic clause does not reach it. This was checked against both amending orders since the consolidated text: neither the Dangerous Drugs (Amendment of First Schedule) Order 2024 nor the 2025 order mentions it. So on the text HHC is not a dangerous drug, as the schedule stood at 25 November 2025. Hexahydrocannabinol was added to Schedule II of the 1971 Convention with effect from December 2025, and section 45A exists precisely so the Minister can follow such a decision by order.

Consequences if caught

Capital exposure: none. Hexahydrocannabinol is in neither list. Part III of the First Schedule names «delta-8-tetrahydrocannabinol», «delta-9-tetrahydrocannabinol», their hydroxy forms, «Parahexyl» and «Tetrahydrocannabinols» under a fixed chemical designation, and hexahydrocannabinol is none of them: hydrogenation changes the molecular formula, so it is not an isomer either. The compound is what is absent, and the material is a separate question: a product made from resin-bearing cannabis plant material is cannabis within the section 2 definition, «any part of any plant of the genus Cannabis from which there is found to be present resin irrespective of its quantity», whatever molecule is being sold. This row is about the compound, and on the compound the answer is that it is not in the First Schedule. Section 39B is the only capital provision in Malaysian drug law, and section 39B(1) prohibits trafficking in «a dangerous drug», which section 2 defines as «any drug or substance which is for the time being comprised in the First Schedule». A substance outside that Schedule cannot be trafficked within the meaning of section 39B however much of it there is, the section 37(da) presumption weights do not reach it, and neither do the section 39A enhanced penalties. It is not in the Third Schedule to the Poisons Act 1952 either, so the section 30 psychotropic offence does not reach it. Do not read that as permission. The Dangerous Drugs Act carries no analogue clause at all, measured across the whole Act, so a substance is in or out on the naming; but section 45A provides that where the Minister «considers it expedient to add a substance to, or remove a substance from, or vary the First Schedule, he may by order make the requisite modifications», and he has used it twice since the consolidated text, by P.U. (A) 97 gazetted 2 April 2024 and P.U. (A) 416 gazetted 25 November 2025. An order takes effect on gazetting and there is no notice period. Customs may also treat an unlisted substance as a prohibited import under a separate order that was not read for this cell.

If prescribed or medical

Neither drug statute reaches HHC, so neither supplies a prescription route for it and neither requires one. Part III names delta-8-THC, delta-9-THC, their hydroxy forms, «Parahexyl, 3-hexyl-1-hydroxy-7, 8, 9, 10-tetrahydro-6, 6, 9-trimethyl-6H-dibenzo» and a tetrahydrocannabinol entry under a specific chemical designation. Hexahydrocannabinol is the hydrogenated form with no double bond in the ring, so it is not a tetrahydrocannabinol, and hydrogenation changes the molecular formula so it is not an isomer of one either. It was added to Schedule II of the 1971 Convention with effect from December 2025, and section 45A exists so the Minister can follow such a decision by order. What this cell does not state is whether it is a registered product, an unregistered product or a prohibited import under the medicines and customs instruments, because none of those instruments was read for it.

Documentation

No documentation requirement arises under either drug statute, because neither reaches HHC. There is no entry for a document to answer to as the Schedule stood on 25 November 2025, and the December 2025 Convention listing is the reason that sentence carries a date. That is not the same as saying it may be brought in freely. Product registration with the National Pharmaceutical Regulatory Agency and the customs prohibited imports orders are separate regimes, neither was read for this cell, and nothing is stated here about either. Carry any prescription and the original packaging as a matter of course, and expect the question at the border to be settled by those other regimes rather than by the Dangerous Drugs Act 1952 or the Poisons Act 1952.

Drug laws and enforcement change and vary within a country. This is not legal advice. Always confirm with Malaysia’s embassy or official drug authority before traveling; penalties can be severe, including imprisonment.
