Cannabis seeds and the law in Thailand

Cannabis is not a narcotic in Thailand. The plant was removed from the country’s narcotics schedule in June 2022, and it has not been put back. What has changed since is how the plant is regulated once it flowers — not whether the plant exists lawfully.

The restriction introduced in June 2025 applies to cannabis inflorescence: the flower. Seeds are not the controlled item under it, and this shop sells seeds, delivered inside Thailand only.

What Thai law has never done is set out a separate, explicit position on seeds the way some countries do, so anyone telling you the question is fully settled is overstating it. Two things are settled: seeds are not narcotics, and growing the plant they become is regulated. Buying a seed and germinating it are different acts, and it is the second one the state asks you to register.

Three separate regimes could conceivably touch a cannabis seed in Thailand, and it is worth being precise about which ones do.

The narcotics schedule

Every part of the cannabis and hemp plant was removed from Category 5 in June 2022, with one carve-out that has nothing to do with seeds: extracts containing more than 0.2% THC by weight remain narcotics, and still do. A seed is not an extract. It is not scheduled.

The controlled-herb notification

The instrument that took effect on 26 June 2025 designates cannabis inflorescence — the flower — as a controlled herb dispensable only against a prescription. It regulates the flower as a category. Seeds are not inflorescence and are not named in it.

Hemp licensing

This is the one that does name seed, and the one usually left out. If you are cultivating under a hemp licence — hemp being defined in Thailand as cannabis with no more than 1% THC by dry weight in its leaves and inflorescence — then propagation material must be sourced from a licensed seed producer, cultivation is confined to the area named on the licence, and THC testing must be done at an accredited laboratory. That is a requirement about seed, and it falls on the grower rather than on the retailer. If a hemp licence is your intended route, confirm the seed-sourcing condition with your licensing authority before buying anything, from us or anyone else.

For an ordinary buyer who is not cultivating under a hemp licence, none of the three regimes makes the seed itself the regulated object. What is regulated is what you do next.

We sell to adults aged 20 and over. Thailand’s controlled-herb rules have set 20 as the age limit for cannabis since June 2022 and have not moved it; we apply the same limit to seeds rather than argue about whether it reaches them.

We deliver inside Thailand only. We do not ship abroad and we do not arrange import, which keeps the chain of custody short and domestic — a point that matters more than it sounds for licensed growers, because seed that has crossed a border adds an import question to an already unsettled provenance question.

Packaging is discreet, and discretion is not a legal position. Nothing on the outside of a parcel identifies the sender or the contents because customers reasonably prefer that, not because it changes what you may lawfully do with what is inside.

Buying seeds commits you to nothing. Storing them commits you to nothing — seeds keep for years in a cool, dark, dry place. Germinating them is the point at which cultivation begins, and cultivation is the notifiable act described below.

The Ministry of Public Health issued the Notification on Controlled Herbs (Cannabis) B.E. 2568, which took effect on 26 June 2025. It reclassified cannabis flower as a controlled herb under Thailand’s traditional-medicine law, ending the period in which a dispensary could sell to anyone who walked in.

Under it, cannabis flower may be dispensed only against a prescription written by an authorised practitioner — a doctor, dentist, pharmacist or Thai traditional medicine practitioner — on the official PT 33 form. Flower that is sold or exported must come from a cultivation site certified under Good Agricultural and Collection Practices.

Two ministerial regulations tightened commercial licensing again in April 2026. The regulation on Category 5 narcotics covering cannabis and hemp extracts, in force 26 April 2026, restricts who may be licensed to produce, import, export, sell or possess high-THC extracts — in practice Thai juristic persons that are not "foreign" under the Foreign Business Act B.E. 2542, government agencies and the Thai Red Cross Society. Ministerial Regulation No. 2 B.E. 2569, in force 30 April 2026, sets cumulative conditions on anyone licensed to sell flower, including trained staff present throughout opening hours.

None of this changes the position on seeds. It is set out here because it is what the seed becomes, and because a grower planning to sell what they harvest needs to know the shape of the market they are growing into.

Not without registering it. Cultivation has been a notifiable activity since 2022, through the FDA’s registration system — the one most people know as the Plook Ganja app — and the notification is the point at which the state records who is growing, where, and how much.

Growing for your own medical use and growing to supply anyone else are two different undertakings with two different sets of paperwork. Anything you intend to sell as flower has to come from a GACP-certified site, which is an inspection regime rather than a form.

If you are not a Thai resident, do not assume any of this is open to you. Registration presumes a legal residence in Thailand, and the consequences of getting it wrong fall harder on foreign nationals. Check your own position before you plant anything.

GACP — Good Agricultural and Collection Practices — is the cultivation standard certified by the Department of Thai Traditional and Alternative Medicine. Certification follows an audit covering soil, water, pesticide use, worker hygiene and post-harvest handling, runs for one to three years, and carries annual surveillance.

Certified growers have to keep records, and the first of those records is seed provenance: where the genetics came from, and evidence of what they are. Every variety in this catalogue publishes its parentage, arrives in sealed and labelled packaging, and comes with a dated invoice naming the varieties and quantities. That is the paperwork we supply.

Tell us what your licence or your auditor requires when you place the order and we will prepare it alongside the shipment. It is easier to do at the time than to reconstruct afterwards. What we will not do is issue a document asserting something we cannot stand behind — we cannot certify your site, and we will not produce a cannabinoid figure for a crop we did not grow.

This is a plain summary of published regulation, written by a seed retailer. It is not legal advice, and it cannot take account of your circumstances — your residence status, what you intend to grow, or what your licence says.

Thai cannabis regulation has changed materially three times since 2022 and is likely to change again. Where a decision turns on it, confirm the current position with the Thai FDA or the Department of Thai Traditional and Alternative Medicine, or take advice, rather than relying on any commercial site including this one.
