Is 2-FDCK legal in Thailand?

Legal status

2-FDCK is a Category 1 psychotropic substance in Thailand, by name. The Ministry of Public Health notification ประกาศกระทรวงสาธารณสุข เรื่อง ระบุชื่อวัตถุออกฤทธิ์ในประเภท ๑ (ฉบับที่ ๓) พ.ศ. ๒๕๖๗, signed on 18 September 2567 and published in the Royal Gazette volume 141, special part 281 ง, page 23, on 11 October 2567 (2024), added it as item 54 of the Category 1 psychotropic list: "๒-ฟลูออโรเดสคลอโรคีตามีน (2-fluorodeschloroketamine)", with the chemical name "2-(2-fluorophenyl)-2-(methylamino)cyclohexan-1-one". That is the structure PubChem records for 2-fluorodeschloroketamine under CID 13771618. The amendment took effect the day after publication, and it inserts the entry into the B.E. 2565 list, whose clause 2 extends every entry to any stereoisomer and any salt, ester or ether. Ketamine itself is a separate entry in psychotropic Category 2, so 2-FDCK sits one category above its parent. Section 94 of the Narcotics Code B.E. 2564 prohibits producing, importing, exporting, selling, possessing or transiting a psychotropic substance without a licence under section 35(5), and section 149 carries the penalties.

Consequences if caught

Capital exposure: none. 2-FDCK is a psychotropic substance. No provision of the Narcotics Code B.E. 2564 sets death for any psychotropic substance. Life imprisonment is reachable for a psychotropic only under section 172, which punishes inducing, deceiving, threatening or forcing another person to use one: up to 5 years or a fine up to 500,000 baht or both, 1 to 10 years with a weapon or two or more offenders acting together, and 3 years to life and a fine of 300,000 to 5,000,000 baht where the person is a woman or aged 18 or under, or the purpose is a criminal offence. The ordinary penalties are in section 149. For Category 1, section 149 paragraph 1(1) reads "วัตถุออกฤทธิ์ในประเภท ๑ ต้องระวางโทษจำคุกไม่เกินสิบปี และปรับไม่เกินหนึ่งล้านบาท": up to 10 years and a fine up to 1,000,000 baht for unlicensed production, import, export, sale or possession. Section 149 paragraph 2 raises that to 1 to 15 years and a fine of 100,000 to 1,500,000 baht where the conduct is for trade, spreads use among the public, is a sale to a person aged 18 or under, is a sale in the vicinity of a school, a place of worship or government premises, or involves force, the threat of force, or a weapon. Use carries up to 1 year or a fine up to 20,000 baht or both under section 162, and possession for use up to 2 years or a fine up to 40,000 baht or both under section 164. Before 12 October 2567 the compound was not on the Category 1 list, so any account written before that date can be out of date on this point. The death alternative in this Code sits only in section 145 paragraph 3, it belongs to Category 1 narcotics, and a psychotropic placement does not carry a person into it, whatever the quantity. Section 146 covers narcotic Categories 2 and 4 and is not this substance's section.

If prescribed or medical

No lawful route for a traveller was found. Section 39 paragraph 2 of the Narcotics Code B.E. 2564 exempts a traveller carrying a psychotropic substance of Category 2, 3 or 4 for personal treatment, up to a 30 day quantity with a prescription or certificate from a physician, dentist or first class veterinarian. Category 1 is not in that list, so it does not reach 2-FDCK, and a foreign prescription cannot create it. Any lawful possession would need a licence under section 35(5).

Documentation

Carry nothing that contains 2-FDCK. A product sold as a ketamine alternative should be treated as this Category 1 entry, not as ketamine, because the analysis decides which entry applies. The placement was read on 3 October 2026 from the Thai FDA Narcotics Control Division copy of amendment No. 3 at https://narcotic.fda.moph.go.th/law-type/pc-203, checked against the rendered Gazette page because the PDF text layer is garbled, and the base B.E. 2565 list at https://narcotic.fda.moph.go.th/law-type/pc-185 and the later amendments No. 4 and No. 5 (pc-211 and pc-183, the last gazetted 17 September 2569) were read as well; neither later amendment touches item 54. The penalties were read from the Code at https://narcotic.fda.moph.go.th/law-type/na-10. No express open reuse licence was located on the cited pages, so only the wording needed for verification is reproduced, with attribution and a direct link. The status is stated as in force on 3 October 2026, and a later notification can move it, so re-read before relying on this.

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