Cannabis flower is legal for medical use only. It is a controlled herb under Thai Ministry of Public Health rules, and every purchase needs a valid medical-cannabis prescription (form ภ.ท.33 / "PT 33") issued by a licensed practitioner after an in-branch consultation. We work within these rules at every branch.
Public consumption is prohibited and can lead to fines. Keep your flower in its original labelled packaging together with your prescription.
Cash, credit and debit cards, contactless payments such as Apple Pay, and Alipay are all accepted at every branch. You are not limited to cash here.
