Is Methylone legal in Netherlands?

Also known as: bk-MDMA

Legal status

Controlled as a hard drug. Methylone is named in lijst I of the Opiumwet, the hard drug list, and the row prints «methylon | (RS)- 2-methylamino-1-(3,4-methylenedioxyphenyl)propaan-1-on». Lijst I placement decides the regime, because article 2 supplies the prohibitions and article 10 the ceilings.

Consequences if caught

It is named individually in lijst I as methylon. That is worth stating plainly because the substance is commonly described as having been caught only by the 2025 substance group ban, and the list names it in its own right. Use is not itself made an offence by the Opiumwet, which is why the Dutch position is often misread: article 2 and article 3 reach import, export, cultivation, preparation, sale, supply, transport, manufacture and presence, and presence is what a traveller carrying the substance has. Article 1, second limb, equates the salts of a substance with the substance itself. Article 10 carries the penalties for lijst I. Intentionally having the substance present, the limb at article 2 under C, carries imprisonment of up to 6 years. Intentionally cultivating, preparing, processing, selling, delivering, supplying, transporting or manufacturing it, article 2 under B and D, carries up to 8 years. Intentionally bringing it into or out of Netherlands territory, article 2 under A, carries up to 12 years, so the trafficking and import limbs run from 8 to 12 years. Where the presence, or the bringing into or out of the territory, concerns a small quantity intended for own use, article 10, sixth limb, lowers the ceiling to 1 year or a fine of the third category; it does not reach the article 2 under B and D acts. The fine on the serious limbs is the fifth category, which the Criminal Code prints at 67.000 euro with an editorial note recording 110.000 euro from 1 January 2026. They describe the offences that this row's placement brings into play. The Aanwijzing Opiumwet of the Openbaar Ministerie is prosecution policy and not a statute. For lijst I it treats as a small quantity for own use one bolletje, one ampul, one wikkel or one pill or tablet, in any event a quantity of at most 0,5 gram, and for GHB one consumption unit of 5 ml, with no targeted investigation and prosecution only in support of care. A tolerated quantity is not a lawful one. The live cell recorded a ceiling of up to 3 years and a fine of about 82,000 euro, sourced to a Library of Congress note on the 2025 group ban, and contrasted it with mephedrone's 2010-era control. Those figures belong to article 10c, the preparatory offence, and not to the principal ceiling, and they are carried forward from it and not verified here. The reading these cells previously rested on was the Opiumwet consolidation in force from 9 July 2026, and the 17 September 2026 consolidation read here supersedes it. Article 3a of the Opiumwet lets substances be added to lijst I or lijst II by algemene maatregel van bestuur: under the first limb when they come under the Single Convention or the Psychotropic Substances Convention or must be brought under the Act under Framework Decision 2004/757/JHA or Decision 2005/387/JHA, and under the second limb when they are shown to affect human consciousness and can harm health and society. Under the fifth limb the Minister may designate a substance by ministerial regulation, for at most a year, where a ban cannot wait for that order. The lists can therefore move without an amendment to the Act.

If prescribed or medical

Article 2 of the Opiumwetbesluit forbids prescribing an Opiumwet substance unless one of the two bijlagen to that decree names it, and neither names this one. There is accordingly no lawful prescription route for it outside research under the Wet medisch-wetenschappelijk onderzoek met mensen. No article 75 Schengen certificate is available for it either, because that route presupposes a prescribed medicine.

Documentation

Methylon is named individually in lijst I, so the account of it as a substance reached only by the substance group list that took effect on 1 Jul 2025 understates the position. There is no lawful personal import route, because article 2 under A of the Opiumwet prohibits bringing a lijst I substance into or out of the territory and no traveller exemption covers it.
