Table of Contents
Thailand has become a hotspot for cannabis enthusiasts ever since it legalized cannabis in 2022. With dispensaries popping up across major tourist destinations like Bangkok, Chiang Mai, and Phuket, it’s now easier than ever to find high-quality Thai weed. However, a common question among travelers is: Can I fly with weed in Thailand domestically?
If you’re planning to take a domestic flight in Thailand and wondering whether you can bring your cannabis with you, this guide will break down everything you need to know—from legal regulations to airport security policies and the safest way to travel with cannabis in 2025.
The Legal Status of Cannabis in Thailand (2025 Update)
Before diving into whether you can bring weed on a domestic flight, let’s clarify the current cannabis laws in Thailand as of 2025.
- Cannabis is legal for personal use but regulated under Thai law.
- Medical cannabis is legal, but recreational cannabis exists in a legal gray area.
- Dispensaries are licensed and operate under specific guidelines.
- Public consumption is illegal—you can only smoke weed in private areas like your home or designated smoking lounges.
- Traveling internationally with cannabis is strictly prohibited, even if it’s legal in the country you’re flying to.
The big question remains: Can you carry cannabis on a domestic flight within Thailand?

Can You Fly with Weed on Domestic Flights in Thailand?
The short answer: Yes, but with limitations.
While Thailand has decriminalized cannabis, air travel falls under stricter transportation regulations. Here’s what you need to know:
What’s Allowed on Domestic Flights?
✅ Personal use amounts – The law does not specify a strict limit, but anything under 5 grams is generally considered personal use.
✅ CBD and low-THC products – Products with less than 0.2% THC are legal and can be transported.
✅ Medical cannabis with documentation – If you have a doctor’s prescription for medical marijuana, it’s safer to carry a copy of your prescription.
What’s Not Allowed on Domestic Flights?
❌ Large amounts of cannabis – Carrying excessive amounts (e.g., 50g+ or bulk quantities) could be flagged as intent to distribute.
❌ Strong-smelling weed without proper storage – Unsealed or improperly packed cannabis might cause issues with security.
❌ Cannabis extracts with high THC – Some infused products (like concentrates, edibles, and oils) are in a gray area and could be questioned at security checkpoints.
Should You Declare Cannabis at the Airport?
- At Thai airports, there is no official requirement to declare personal-use cannabis when traveling domestically.
- However, if security officers check your bag and find cannabis, it helps to be informed and prepared with receipts from a legal dispensary.
- If you carry medical cannabis, having documentation from a Thai doctor will make security checks easier.
How Do Airports in Thailand Handle Cannabis?
Most Thai airports, including Suvarnabhumi (Bangkok), Don Mueang, Chiang Mai, Phuket, Krabi, and Samui, have no explicit ban on carrying cannabis within Thailand. However, security checks vary by airport.
Airport Security Screening Process
- Your luggage will go through X-ray screening, and officers might manually inspect bags if something suspicious appears.
- Security personnel do not actively search for cannabis but will flag questionable items.
- If cannabis is found and packaged properly, it’s unlikely to cause issues.
- If there are concerns (such as carrying excessive amounts), officers may ask for purchase receipts or medical prescriptions.
Best Practices for Carrying Cannabis Through Thai Airports
✔ Store cannabis in airtight containers to minimize smell.
✔ Keep dispensary receipts as proof of legal purchase.
✔ Avoid carrying cannabis-infused edibles or concentrates unless labeled with THC content.
✔ If questioned, stay calm and explain it’s for personal use.
Do Airlines Have Their Own Policies?
Different airlines in Thailand may have their own policies regarding cannabis transportation.
Thai Airways
- Thailand’s national carrier does not allow cannabis on international flights.
- On domestic flights, there is no clear rule against it, but they advise passengers to follow legal guidelines.
Bangkok Airways
- No official stance on cannabis for domestic flights, but they align with Thai regulations.
- Carrying small personal amounts should not be an issue.
AirAsia Thailand & Thai Lion Air
- Both budget airlines prohibit passengers from consuming cannabis onboard.
- No official ban on carrying cannabis in checked or carry-on luggage.
Nok Air & Thai VietJet Air
- These airlines focus on budget travel and do not actively restrict domestic cannabis transportation.
- However, they follow standard airport security procedures.
Conclusion: Airlines do not have strict bans, but security screenings are handled by the airport rather than the airline itself.

Is It Safer to Carry Cannabis in Checked or Carry-On Luggage?
One of the biggest concerns is whether it’s better to pack your cannabis in carry-on luggage or checked baggage.
Carry-On Luggage
Pros:
✅ You have direct control over your items.
✅ If security questions your cannabis, you can explain it’s for personal use.
✅ It’s easier to present proof of purchase or documentation.
Cons:
❌ If security finds cannabis, they may ask you to remove it.
❌ The strong smell might trigger additional screening.
Checked Baggage
Pros:
✅ Less likely to be checked manually unless flagged by an X-ray.
✅ No risk of security questioning you directly during check-in.
Cons:
❌ If your bag is flagged, you won’t be able to explain it until you land.
❌ Airport staff might confiscate cannabis if they think it violates regulations.
Best Practice: If you’re carrying a small amount, it’s generally safer in your carry-on luggage—properly sealed and packed to avoid unnecessary attention.
What Happens If You Get Caught with Cannabis at a Thai Airport?
While there is no outright ban on carrying cannabis domestically, here’s what could happen if airport security questions you:
🚨 Best-Case Scenario: You show your purchase receipt or prescription, and they let you go.
⚠️ Mild Issue: They ask you to discard the cannabis before boarding.
❌ Worst-Case Scenario: If they suspect you’re carrying an excessive amount with intent to distribute, they could escalate the situation.
How to Handle the Situation:
✔ Stay calm and cooperative.
✔ Show proof that your cannabis was legally purchased.
✔ Reiterate that it’s for personal use only.
✔ If asked to discard it, do so without resistance.
Key Takeaways: Can You Fly with Weed in Thailand?
✅ Yes, you can carry cannabis within Thailand on domestic flights, but only for personal use.
✅ Stick to small amounts (under 5g) and store it in smell-proof containers.
✅ Do not attempt to fly internationally with cannabis.
✅ Keep dispensary receipts or medical documentation for smooth security checks.
✅ Pack it in carry-on luggage rather than checked bags for better control.
