Is Delta-8-THC legal in Thailand?

Also known as: d8

Legal status

Controlled by THC content, under the Narcotics Code (B.E. 2564) and the 2022 cannabis reform, any cannabis/hemp EXTRACT containing more than 0.2% tetrahydrocannabinol by weight remains a Category 5 narcotic; delta-8-THC (Δ8-THC) is caught as a tetrahydrocannabinol above that threshold, controlled by its THC content rather than named. Distinct from cannabis buds/plant, largely decriminalised post-2022 subject to tightening rules. No death penalty. [Likely] That finding is carried forward from the entry published before this batch and was not re-derived from statute in this pass. Not confirmed for Delta-8-THC, and the reason is a reach question that did not settle rather than an absence that did. The search ran in Thai and in Latin script across the Thai FDA narcotics table updated 15 September 2025 and the B.E. 2565 psychotropic naming notices. The nearest entry it reached was tetrahydrocannabinol, and that was rejected because it is a different molecule and this scheme names molecules rather than families. A double bond in a different position is a different isomer, and the table was not read as naming the isomers generically. A second check of the Narcotics Code's salts, derivatives and preparations language and of the Minister's notification power did not establish that Delta-8-THC is automatically caught, so the exact criminal classification remains open. This is not a finding that Delta-8-THC is uncontrolled in Thailand, and it is not a finding that the near entry catches it either.

Consequences if caught

Capital exposure: not established. No capital and no life exposure can be stated for Delta-8-THC and neither can be ruled out, because no category was proved and in this scheme the ceiling follows the placement: with the placement open there is no section 145, 146 or 149 figure to attach. The rejected near entry carries its own exposure and it is not this substance's, since tetrahydrocannabinol is the cannabis constituent the extract rules turn on. If a later notification placed Delta-8-THC in Category I, the section 145 paragraph 3 death alternative would still be discretionary and circumstance based, reserved for an organised network leader or a state or public security impact, and never triggered by a stated quantity. Treat the risk as unquantified rather than as low. A double bond in a different position is a different isomer, and the table was not read as naming the isomers generically, so the exposure the named cannabinoid carries is not available to state here.

If prescribed or medical

No proved schedule placement exists for Delta-8-THC in this reading, so there is no category to attach a medical or traveller route to. Thailand's country level traveller rule for personal medication was not established by this reading. The sources opened were the Narcotics Code B.E. 2564, the Thai FDA narcotics table updated 15 September 2025 and the B.E. 2565 psychotropic naming notices in the Royal Gazette, and the dossier is explicit that its findings come from those naming instruments and not from a traveller permit label, so no import permit route, no personal supply quantity ceiling and no certificate requirement can be stated here for Delta-8-THC. Two things are open at once here, the classification and the permission, and the second cannot be answered before the first. What is missing from this row is the permission, not the classification, and the gap is in what was read rather than a finding that no lawful route exists. The cannabis and CBD rows in this set run on the extract and controlled herb instruments rather than on the narcotics table, and neither was read as answering this isomer.

Documentation

Carry the search record rather than a conclusion: for Delta-8-THC the sweep covered the Thai FDA narcotics table updated 15 September 2025 and the B.E. 2565 psychotropic notices, reached tetrahydrocannabinol as the nearest entry, rejected it as a different molecule, and stopped there. Check which isomer is named in any instrument relied on, because the table was not read as naming them generically. The reading was taken on 20 September 2026 from the consolidated narcotics table, read alongside the psychotropic naming notices, at https://narcotic.fda.moph.go.th/media.php?id=808160206197497856&name=NARCO+list+(update+15.09.2025)+NEW.pdf. No express open reuse licence was located on the cited page, so only the wording needed for verification is reproduced, with attribution and a direct link. The names and categories are set by ministerial notification, and the publications do not certify that no later notification exists, so re-read before relying on this.
