Questions

Quick answers.

Is cannabis legal in Thailand?

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.

Do I need a prescription, and how does it work?

Yes. A prescription is required for every purchase. A licensed practitioner runs a consultation and assessment to decide whether cannabis is medically appropriate for you. If it is, they issue a form ภ.ท.33 / "PT 33" prescription, valid for up to a 30-day supply. The decision rests entirely on the practitioner's medical assessment. You will also need photo ID or a passport, and you must be 20 or older.

Can visitors from outside Thailand access medical cannabis?

Yes, with a prescription from a licensed practitioner in Thailand. Prescriptions and medical cards from other countries are not valid here, and importing or exporting cannabis is prohibited. Bring photo ID or your passport, and remember you must be 20 or older.

What else should I know?

Public consumption is prohibited and can lead to fines. Keep your flower in its original labelled packaging together with your prescription.
