Questions about the rules.

Which cannabis rules should operators read first?

Start with the 2025 Controlled Herb notification for cannabis-flower controls and the 2026 licensing amendment for premises, storage, staffing and licence requirements. Reporting forms are covered by separate DTAM notices.

Has the Cannabis Control Act taken effect?

The Ministry’s 20 July 2026 update describes it as a draft submitted to the Health Minister before Cabinet consideration. That update does not announce an effective date. A draft’s proposals should not be treated as rules already in force.

Can tourists buy or use cannabis flower in Thailand?

TAT advises that tourists need a valid prescription issued in Thailand by an authorized practitioner to buy, carry or use cannabis flower for medical treatment. The quantity must be medically necessary and cannot exceed a 30-day supply. Recreational use is not permitted.

Can I smoke cannabis in public?

Avoid smoking cannabis in public. The Department of Health says smoke or odour that causes a public nuisance is unlawful and can trigger enforcement under the Public Health Act. A medical prescription does not exempt you from those nuisance rules.

Can I bring cannabis or CBD products into Thailand?

Do not assume a foreign prescription or a CBD label permits import. Thai FDA guidance prohibits cannabis- and hemp-based foods; other health products have their own import restrictions. Check the exact product with Thai FDA before travelling.

Can I take cannabis bought in Thailand home?

Buying a product in Thailand does not authorize taking it across a border. Thailand’s Department of Consular Affairs warns that carrying cannabis on flights can lead to offences in Thailand or abroad. Check Thai export rules and the laws of your destination and transit countries before packing it.

Do PT27 and PT28 still apply under the 2025 rules?

Yes. The DTAM notice dated 30 June 2025 keeps the earlier reporting forms in use under the 2025 rules and adds the PT33 controlled-herb prescription form.

What is PT33 used for?

PT33 is the controlled-herb prescription form completed by an authorized practitioner. It records the practitioner and patient, the assessed condition, and the prescribed quantity and duration.

Where can I download the blank forms?

The form library includes PT27, PT28, PT29 and PT33 templates, including an English PT33. Confirm the current template and filing procedure with DTAM or your provincial public health office before submitting.
