No Medical Cannabis Card in Thailand: Only a Prescription Required

If you’re in or traveling to Thailand soon and you’ve been told you may need a “medical cannabis card” to legally buy or use weed, I need to set the record straight.

There is no such thing as a government-issued medical cannabis card.

It doesn’t exist. It never did. And in 2025, that myth is holding people—and businesses—back from understanding what really matters.

Here’s what actually makes cannabis legal for medical use in Thailand: a PorT...

So What Is a PorThor 33?

It’s a 30-day cannabis prescription, issued by a trained medical professional and approved by Thailand’s Department of Thai Traditional and Alternative Medicine.

To be valid, the form must include:

Your name and ID

Your medical condition or diagnosis

Recommended product and dosage

The prescriber’s license number, full name, clinic address

A wet signature from the prescriber

Your signature as patient

The dispensary must keep the physical, wet-signed copy on file for compliance and stay compliant for random check by DTAM forces. That’s the law. A digital version is fine for your own records, but it doesn’t legally authorize a sale.

Why Doctors Are Still Reluctant to Prescribe

Here’s the part nobody likes to say out loud.

Most doctors in Thailand—even those legally eligible—still don’t want to prescribe cannabis.

They’re not comfortable with it

So while you might technically be able to get a PorThor 33 from any certified physician, in practice, very few want to issue one.

That’s why most prescriptions today are coming from Thai Traditional Medicine Doctors—not general practitioners. Traditional practitioners have more experience navigating herbal frameworks and are typically more willing to prescribe for broader symptoms like insomnia, pain, stress, or appetite issues.

July 16, 2025: The Big Shift

The Ministry of Public Health is now formalizing the system.

By July 16, 2025, the first 1,000 practitioners in Thailand will complete official cannabis prescription training. These are the only professionals who will be authorized to issue PorThor 33 forms going forward.

This is the start of a fully certified, trackable national program. From this point on, any doctor or practitioner issuing prescriptions must be trained—and that training will become public knowledge. No more ambiguity.

That also means access is going to tighten before it expands. If your go-to doctor hasn’t completed the training, they won’t be allowed to prescribe, even if they want to. Clinics, dispensaries, and patients need to be ready for that change.

Why Most Shops Aren’t Enforcing This

If all this sounds strict, you might wonder: then why are so many dispensaries still selling cannabis without asking for any of this?

Simple answer: they haven’t read the regulations.

The Ministry of Public Health published the updated PorThor 33 framework and ...

But ignorance won’t protect anyone.

If you’re a dispensary and you’re selling without holding the signed PorThor 33 from each patient, you are out of compliance. If you’re a patient and you’re buying without one, you’re not legally covered under Thailand’s Controlled Herb Act.

It’s not about fear. It’s about understanding the game you’re in and play by the rules.

What About Online “Cannabis Cards”?

Plenty of platforms still advertise things like “get your medical cannabis card online.” But here’s the truth: if they’re legitimate, what they’re really offering is a PorThor 33 prescription—just dressed up with a downloadable card, a QR code, or a slick membership badge.

Let me be absolutely clear: the card itself is meaningless without the actual prescription. It’s just marketing. What matters is whether the platform provides a valid, government-compliant PorThor 33, signed by a trained and certified practitioner.

If it doesn’t—then it’s not protecting you, and it’s not protecting the dispensary.

That’s exactly why I built CannaboxMD.

CannaboxMD isn’t a “cannabis card” service. It’s a legally compliant telemedicine platform designed specifically for Thailand’s cannabis regulations. We work directly with licensed clinics and trained Thai Traditional Medicine doctors, follow all current telemedicine laws, and—crucially—we handle the delivery of the wet-signed prescription to your chosen dispensary so that they stay compliant too.

No shortcuts. Just the right paperwork, issued the right way.

So if you’re going online for your cannabis prescription, make sure you’re not just getting a digital sticker. Choose a platform that understands the law, respects the process, and handles it end to end. Choose CannaboxMD.

What to Actually Do If You Want to Stay Legal?

If you want to access cannabis legally in Thailand under the July 27th, 2025 framework, here’s what you need to understand:

You need a PorThor 33. Not a card. Not a promise. A real, signed prescription.

You need to get it from a certified practitioner—and after July 16, that means someone who’s completed the government training.

You can only purchase from the dispensary which you submitted your prescription.

You need to renew it every 30 days.

If you want to purchase from a different dispensary, you’ll need a new prescription. Dispensaries are required by law to hold the original, wet-signed copy for compliance.

If you’re using an online service, make sure it complies with Thailand’s telemedicine laws and can arrange delivery of the wet-signed prescription to the dispensary where you plan to purchase.

Anything else is just marketing.

Final Words

I’ve been working in cannabis in Thailand long enough to see this shift happe...

That gap is about to close.

If you’re a patient, get the PorThor 33. If you’re a shop owner, require it from every customer. The enforcement may not be visible yet—but the structure is already in place.

And come July 16, things will get much more real.

Forget the card. Know the law. Get the form. That’s how you stay safe in Thailand’s new cannabis era.
