Bringing it in: the questions we can answer and the ones we cannot

Can I bring cannabis into Thailand with me?

Not confirmed — we have no verified source

We have no source we can show you that describes what a visitor may carry in. What we can say is what the arrangement here looks like from the inside: a lawful purchase happens at a licensed counter inside Thailand, against a document issued inside Thailand, and nothing in that arrangement contemplates material arriving from somewhere else.

Treat an unsourced answer as a reason to ask somebody who is accountable for the answer, not as a green light. Customs, an embassy or a Thai lawyer are the people whose answer means something; a dispensary's is not.

I have a prescription from my own country. Does it work here?

Official source

The official tourist notice says a visitor needs a prescription that was issued inside Thailand. A document written by a doctor at home does not answer that description, and no counter can make it answer it.

That is a statement about buying, not about your suitcase — the notice does not describe what happens at an arrivals hall. But it does settle the assumption people usually build their plans on, which is that paperwork from home transfers. It does not.

What about oils, capsules and hemp products bought as supplements at home?

Not confirmed — we have no verified source

Travellers routinely treat these as a separate, softer category, and we have found nothing that supports treating them that way at a border. We are not in a position to tell you they are fine, and we are not in a position to tell you they are not.

What we would say is that the packaging of a supplement is not an argument. The label describes what a shop in another country was allowed to sell you; it says nothing about what an officer here is looking at or how they classify it.

Are seeds a different question?

Not confirmed — we have no verified source

They are a different question and we cannot answer it either. Seeds sit in their own category in most countries' rules, sometimes a lighter one and sometimes a heavier one, and we have no Thai source to point you at.

This is one of the places where the internet is confidently wrong in both directions at once. If it matters to your plans, ask somebody official before you pack rather than after you land.

Can I bring a vape or an e-cigarette?

Practical caution — not a legal conclusion

We do not sell vapes or e-cigarettes in any form, and the reason is that their sale is prohibited in Thailand. A shop that keeps them quietly under a counter is a shop gambling with the licence that lets it open at all.

What that means for your luggage is a customs question rather than ours, and we will not pretend to answer it. But a device you cannot lawfully buy here is not a device to assume is uncontroversial on arrival, and this is one of the more common ways a holiday starts badly.

I am only connecting through Thailand. Does any of this apply?

Not confirmed — we have no verified source

We do not know, and anybody who tells you a transit area is outside a country's reach is telling you something they have not checked. What we would say is that a connection is not a guarantee: diversions happen, connections are missed, and a night in an airport hotel puts you through an immigration desk you had not planned on.

The mirror of this question — a layover on the way out of Thailand — is dealt with on the page about going home, where the same reasoning applies with a different set of consequences.

So what is the sensible plan?

Practical caution — not a legal conclusion

Arrive with nothing and deal with the question here, where it has a defined answer: a licensed counter, a document issued in Thailand, an age line at twenty, and a purchase made in person. Every part of that is describable, and this site describes it.

The alternative asks you to guess about a border in advance, with no source to guess from and a bad downside if you guess wrong. There is no upside on the other side of that trade that a visitor could reasonably want.

Is there an age line I should know about before I plan anything?

Official source

Twenty. The government notice treats cannabis flower as a controlled herb sold under a prescription, and the age line at a counter here is twenty and over, with a passport as the document that proves both age and identity for a foreign visitor.

This is about buying rather than about arriving, but it belongs on a page read before a trip: a plan built around somebody who will not be sold to is a plan that fails at the counter rather than at the border.

Who should I actually ask about the unanswered ones?

Practical caution — not a legal conclusion

In order of usefulness: Thai customs, your own country's embassy here, and a lawyer practising in Thailand. Each of those is accountable for what they tell you in a way that a shop, a forum and a travel blog are not.

Your airline is worth a message too, for a narrower reason: they are the ones who will refuse to carry something, and they answer that question in writing. That is a lower bar than legality and a much faster answer.
