Cannabis is a controlled herb in Thailand, sold as flower for medical use only under Ministry of Public Health rules. Every purchase needs a valid medical-cannabis prescription (form ภ.ท.33 / PT 33), issued by a licensed practitioner after an in-branch consultation and assessment. We are a licensed dispensary, not a clinic, so our team guides you through that process rather than issuing the prescription ourselves. Bring photo ID or your passport; you must be 20 or over, and public consumption is prohibited. If you are visiting Thailand, note that foreign prescriptions are not valid here and importing or exporting cannabis is prohibited.
