Is Xylazine legal in Malaysia?

Legal status

Xylazine is a poison under the Poisons Act 1952, listed in the Poisons List by name with «All preparations» against it and grouped with the veterinary and analgesic entries. It is NOT in the First Schedule to the Dangerous Drugs Act 1952 and it is not a Third Schedule psychotropic substance, so section 39B and the death penalty cannot reach it. Where xylazine is found cut into heroin or fentanyl, the drug it is cut into is the dangerous drug and the mixture is weighed as it is found.

Consequences if caught

Capital and life exposure. There is none. Xylazine is not in the First Schedule to the Dangerous Drugs Act 1952, and that settles the capital question. Section 39B, the only capital provision in Malaysian drug law, bites on «a dangerous drug», and section 2 defines that 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. What applies instead is the Poisons Act 1952, but not the section of it that is usually reached for. Section 30 does not apply to xylazine. Section 30(1) provides that «In this section, “psychotropic substance” means any of the substances specified in the Third Schedule», and xylazine is not in the Third Schedule; it is in the Poisons List, as «Xylazine». So the section 30(3) prohibition on possessing and using, the section 30(4) presumption and the section 30(5) penalty of ten thousand ringgit and four years are the wrong provisions for it, and quoting them here would overstate the exposure more than threefold on the fine and fourfold on the term. The provisions that do apply are lighter. Sections 19 to 25 control who may sell and supply a poison. Possession is reached only through the regulations: section 9(1) provides that no person, whether licensed under the Act or not, shall «knowingly sell, supply, keep or have in his possession or under his control or store any poison otherwise than in accordance with the regulations made under this Act and in force relating to the possession, containers, packaging, labelling or storing of such poison», those regulations being the Poisons Regulations 1952, L.N. 440/1952, made under section 35 of the Act, in operation since 1 September 1952 and amended most recently by P.U. (A) 155/2025, whose regulation 5 provides that «No person shall store any poison except in a container impervious to the poison and sufficiently stout to prevent leakage from the container arising from the ordinary risks of handling» and whose regulations 6 to 14 carry the storage, packing and labelling rules. So what is prohibited is holding a poison outside those rules rather than holding it at all, and section 9(2) deems the holding to have been knowing once possession is proved. Section 13 separately covers possessing a poison for sale. Where no other penalty is provided, section 32(2) supplies «a fine not exceeding three thousand ringgit or by imprisonment for a term not exceeding one year or both», rising to five thousand ringgit and two years where the court finds wilful default or culpable negligence that endangered or was likely to endanger human life. Where xylazine is found cut into heroin or fentanyl, the dangerous drug it is cut into governs the exposure and the mixture is weighed as it is found, so the light treatment of xylazine itself can be beside the point. Three thousand ringgit and a year against death is still the largest cliff in Malaysian drug law, and it turns entirely on which of two schedules a substance sits in. The ground can move under it: section 45A of the Dangerous Drugs Act lets the Minister add a substance to the First Schedule by order with no notice period, and section 30(2) of the Poisons Act lets him amend the Third Schedule the same way.

If prescribed or medical

Xylazine is a poison under the Poisons Act 1952 but it is not a psychotropic substance under it, and that distinction decides which sections apply. Section 30(1) provides that «In this section, “psychotropic substance” means any of the substances specified in the Third Schedule». Because xylazine is absent from that Schedule, section 30 and the Poisons (Psychotropic Substances) Regulations 1989 do not reach it at all. What reaches it is the Poisons List, where it appears as «Xylazine», together with the supply provisions in sections 19 to 25. Section 19(1) carries the prescribing route: «a registered medical practitioner may sell, supply or administer such poison to his patient for the purposes of the medical treatment of such patient only», with equivalent provision for a registered dentist Division I and a veterinary officer, and the Group the poison is placed in governs who else may sell or supply it under sections 20 to 23. It is absent from the First Schedule to the Dangerous Drugs Act 1952, so nothing in that Act applies to it. Where xylazine is found cut into heroin or fentanyl, the dangerous drug it is cut into governs the exposure and the mixture is weighed as it is found.

Documentation

Carry the prescription and the dispensing label with the medicine, in its original packaging. That is ordinary prudence rather than a requirement the Poisons Act places on a traveller, because the Act controls who may sell and supply a poison rather than who may hold one. The entry a border officer would be reading is «Xylazine» in the Poisons List. There is no Third Schedule entry for xylazine to be read instead, and that absence is the whole reason the lighter sections apply. The exposure is lighter than for a psychotropic substance and it arises from different sections. Holding an ordinary poison is not prohibited as such: the provision that does prohibit possessing, section 30(3), is confined by section 30(1) to Third Schedule substances. What does touch possession is section 9(1), which provides that no person, whether licensed under the Act or not, shall «knowingly sell, supply, keep or have in his possession or under his control or store any poison otherwise than in accordance with the regulations made under this Act and in force relating to the possession, containers, packaging, labelling or storing of such poison», and section 9(2) deems that to have been done knowingly once possession is proved. So the offence is possessing a poison otherwise than in accordance with those regulations, and not possessing it at all. The regulations section 9(1) refers to were not located in this session and nothing is stated here about what they require. Section 13 separately covers possessing a poison for sale. An offence against the Act for which no other penalty is provided is punishable under section 32(2) by «a fine not exceeding three thousand ringgit or by imprisonment for a term not exceeding one year or both», rising to five thousand ringgit or two years where the court finds wilful default or culpable negligence that endangered or was likely to endanger human life. The Poisons (Psychotropic Substances) Regulations 1989, including the one month personal import allowance in regulation 4(2)(a), do not apply to xylazine, because they apply to Third Schedule psychotropic substances and it is not one.

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.
