Free Cannabis Prescription in Ko Samui: Buy Legally

Since June 2025, buying cannabis flower in Thailand legally requires a medical prescription — the PT 33 certificate. That sounds like a hassle. At Magical Garden in Fisherman's Village, Ko Samui, it isn't: everyone aged 20+ is welcome to walk in and buy, and we provide the official PT 33 forms completely free — both physically in-store and digitally — so you can stay compliant in minutes. All you need is your passport — even a clear photo of it on your phone is enough.

Here's exactly how it works, what the prescription covers, and what to expect on your first visit.

Why You Need a Prescription in 2026

In June 2025 Thailand's Ministry of Public Health reclassified cannabis flower as a controlled herb.

This applies to everyone — Thai residents and tourists alike.

How the Free PT 33 Forms Work at Magical Garden

No appointment. No doctor's fee. No paperwork to prepare. The whole process happens in the store:

One visit covers your whole holiday: a PT 33 form stays valid for 30 days, so every purchase after that first one is as simple as walking in.

What Does It Cost?

At Magical Garden: nothing. The official PT 33 forms are completely free — you only pay for what you choose to buy afterwards. Elsewhere on the island, clinics and some shops charge a consultation fee, so it pays to ask before you sit down.
