1P-LSD in Thailand: not individually verified

Not individually verified

We have not confirmed that 1P-LSD specifically is scheduled in Thailand, 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 1P-LSD, because the one entry that could reach it supports two readings and the text does not choose between them. As in force on 3 October 2026, 1P-LSD, PubChem CID 119025985, "(6aR,9R)-N,N-diethyl-7-methyl-4-propanoyl-6,6a,8,9-tetrahydroindolo[4,3-fg]quinoline-9-carboxamide", is not named in any Thai naming notification read. The search ran on 3 October 2026, in Thai, in Latin script and by chemical name, through every Ministry of Public Health naming notification the Thai FDA Narcotics Control Division publishes under the Narcotics Code B.E. 2564: narcotic Category 1 of B.E. 2565 as amended up to No. 5 B.E. 2568, narcotic Category 2, narcotic Category 4 of B.E. 2566 as amended up to No. 3 B.E. 2568, narcotic Category 5, and psychotropic Categories 1 to 4. The LSD entry does not reach it: LSD is item 49 of the narcotic Category 1 list, "เดกซ์โทรไลเซอร์ไจด์ ((+)-lysergide) หรือ แอลเอสดี (LSD)", and clause 2 extends it only to other names for the same structure, stereoisomers, and "เกลือ เอสเทอร์ (ester) และอีเทอร์ (ether)", while 1P-LSD is LSD with a propanoyl amide on the indole nitrogen. The open question is item 26 of the narcotic Category 4 list, "ไลเซอร์จาไมด์ (lysergamide)", whose condition reads "รวมทั้งอนุพันธ์ต่างๆ เอสเทอร์ และอีเทอร์ใดๆ ของยาเสพติดให้โทษดังกล่าว", including its various derivatives, and clause 4 applies the list whatever the concentration or purpose. On its plain words, 1P-LSD, a substituted lysergamide, is such a derivative. Against that, the same list names fourteen ergot alkaloids, items 3, 4 and 12 to 23, among them ergometrine at item 18 and ergotamine at item 22, all themselves substituted lysergamides, as separate entries with their own exceptions for registered medicines, which a broad reading of item 26 would make redundant and override, and item 27, lysergic acid, carries no derivatives condition at all. The Code does not define derivative, and no court reading was searched for in this run. This is not a finding that 1P-LSD is uncontrolled in Thailand.

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

What Thailand HAS confirmed for related substances

LSA (Morning Glory)a related compound, not 1P-LSD
LSA is a Category 4 narcotic in Thailand, the category the Narcotics Code B.E. 2564 uses for chemicals that serve to make Category 1 or Category 2 narcotics. The Ministry of Public Health notification ประกาศกระทรวงสาธารณสุข เรื่อง ระบุชื่อยาเสพติดให้โทษในประเภท ๔ พ.ศ. ๒๕๖๖, signed on 26 December 2566 and published in the Royal Gazette volume 141, special part 17 ง, page 13, on 17 January 2567 (2024), names it at item 26 as "ไลเซอร์จาไมด์ (lysergamide)", chemical name "(6aR,9R)-7-methyl-4,6,6a,7,8,9-hexahydroindolo[4,3-fg]quinoline-9-carboxamide", with the condition "รวมทั้งอนุพันธ์ต่างๆ เอสเทอร์ และอีเทอร์ใดๆ ของยาเสพติดให้โทษดังกล่าว เว้นแต่ไลเซอร์จาไมด์ (lysergamide) ซึ่งเป็นส่วนผสมในตำรับที่ได้ขึ้นทะเบียนยาตามกฎหมายว่าด้วยยา หรือ ขึ้นทะเบียนตำรับวัตถุออกฤทธิ์ตามประมวลกฎหมายยาเสพติด", which takes in its derivatives, esters and ethers and excepts lysergamide inside a formula registered as a medicine under the drug law or registered as a psychotropic formula under the Narcotics Code. PubChem lists LYSERGAMIDE as the first synonym of ergine, CID 442072, the d-lysergic acid amide sold as LSA, with the same ring system and (6aR,9R) configuration. Clause 3 of that notification repealed the B.E. 2565 Category 4 list (https://narcotic.fda.moph.go.th/law-type/nc-346) and its amendment, which had carried the same entry as item 24, and amendments No. 2 and No. 3 B.E. 2568 replaced only items 29 and 37 and added items 39 to 41, so item 26 stands. LSD is a different entry, item 49 of the Category 1 narcotic list. Section 91 of the Code prohibits producing, importing, exporting, selling or possessing a Category 4 narcotic without a licence under section 34 or section 35(1) or (3), and section 146 carries the penalty.

LSDa related compound, not 1P-LSD
LSD is a Category I narcotic in Thailand. The Thai FDA table of controlled narcotic drugs updated 15 September 2025 prints the heading ยาเสพติดให้โทษประเภท 1, narcotics subject to penalty of category 1, and carries LSD as an entry beneath it. This table's 1P-LSD and LSA rows record LSD as the near entry they rejected, so the Category I placement reaches this molecule and not its neighbours. The placement is not written into the Narcotics Code B.E. 2564 itself: section 90 leaves the names and the categories to Ministry of Public Health notification, and the FDA table is the consolidated republication of those notifications, read here through its last Category V entry. So the Code supplies the offence and the penalty while a notification supplies the identity, which is also why this status can move without the statute changing.
