Packaging and labelling rules for cannabis in licensed shops

Thai cannabis packaging went from plain bags to designer jars during the open-retail years. The rules never set a detailed retail labelling standard for flower. What they do set, the sourcing rule, the record-keeping and the advertising ban, shapes what a pack can and should say.

What the flower rules focus on

The controlled-herb rules for flower concentrate on the licence, the PT.33 prescription, the certified source and the PT.27 and PT.28 records, not on pack design. Estimated A pack's first job is therefore traceability: tying what the buyer takes home to the batch, the source and the sale record.

What a flower pack should carry

• The product and quantity.
• The batch or harvest it came from, matching the certificate behind it. See lab testing per harvest.
• The licensed seller.
• Storage and safety information, including that it is not for barred buyers.

Check with DTAM or your provincial public health office for any current requirement before you print.

The advertising ban limits the design

Under the guideline announced on 22 June 2026, advertising controlled herbs for commerce is a 30-day suspension. Estimated Packaging that promotes, with slogans, deals or claims, can drift into advertising. Keep the pack informative, not promotional. See selling online and the advertising rule.

Registered products are different

Foods, cosmetics and herbal products made with cannabis or hemp follow Thai FDA labelling for their category, and ready-to-eat food containing cannabis must carry warnings. Verified See Thai FDA registration for hemp and CBD products.

Brands and the draft Act

As reported, the draft Cannabis Control Act points towards medical use only. Estimated A consumer brand built on packaging and promotion carries more risk under that direction. See is there room for a cannabis brand in Thailand.
