Is smoking legal in Thailand? The short answer
Yes, smoking in Thailand is legal, and the minimum age to buy tobacco is 20. But the list of places where you can’t smoke is long: indoors, public transport, parks, markets, temples, many beaches, and within 5 meters of most building entrances. Smoking in a no-smoking area can cost up to 5,000 baht (about $146).
In practice, you can still smoke on ordinary streets, in the outdoor smoking areas of some open-air bars, and at marked smoking spots. The rules just aren’t always obvious to visitors. Here’s where you can and can’t light up, place by place.
Smoking laws in Thailand: where you can’t smoke
Thai smoking laws work by listing no-smoking places rather than banning smoking in general. Under the Tobacco Products Control Act and a 2018 health ministry order, you can’t smoke in:
| Place | Rule |
|---|---|
| Restaurants and bars with air conditioning | No smoking anywhere, terrace included |
| Open-air restaurants and bars | Not inside or within 5 m of the entrance; a marked outdoor area is allowed |
| Hotels | Common areas and within 5 m of entrances; rooms depend on the hotel |
| Public transport | Taxis, Grab cars, tuk-tuks, buses, trains, boats, planes |
| Stations, piers and airport terminals | Inside, and in waiting areas |
| Parks, markets, zoos and playgrounds | Everywhere, including outdoors |
| Temples and religious sites | No smoking |
| Hospitals and schools | The whole site, plus 5 m from the entrances |
| Malls, shops, museums and cinemas | No smoking |
| Government buildings | Inside; any smoking area must be outdoors |
Smoking in a no-smoking area can bring a fine of up to 5,000 baht. The UK government gives the same figure in its Thailand travel advice.
Smoking on the street and in public
Lighting up on an ordinary sidewalk isn’t illegal in itself. What you need to watch is where you are:
- Keep 5 meters from entrances of shops, malls, hotels, stations and other no-smoking places, and away from bus stops.
- Don’t drop the butt. Under Thailand’s cleanliness law, littering can cost up to 2,000 baht (about $58). Bangkok’s city inspectors, who aren’t police, can issue tickets for it. A real fine comes with a receipt.
- Carry a pocket ashtray. Street bins are rare in Bangkok, so it’s the easiest way to avoid a littering fine.
Khao San Road is the exception. In July 2025, the health ministry declared the whole of Khao San Road a no-smoking area for cigarettes and vapes, including its bars, clubs and shops. We found no similar official ban for Walking Street in Pattaya or Bangla Road in Phuket, but the usual rules still apply there.
Smoking in bars and restaurants
Thailand banned smoking in air-conditioned venues in 2002 and extended it to all bars and clubs in 2008. The current rules split venues in two:
- With air conditioning: no smoking anywhere, including the outdoor terrace.
- Without air conditioning: no smoking inside or within 5 meters of the doors, but the owner can set up a smoking area outside.
That’s why many beach bars and some rooftop bars have a designated corner. If there’s no ashtray on your table, ask before lighting up. Staff usually just ask smokers to step outside, since the venue can be fined too.
Can you smoke on the beach in Thailand?
On many of the most popular beaches, only in the marked smoking spots. In 2018, Thailand’s marine and coastal resources department made busy beaches in its coastal provinces smoke-free, except for marked spots. The original list covered 24 beaches, including:
- Phuket: Patong, where 20 marked smoking spots were set up along the beach;
- Koh Samui: Bo Phut;
- Hua Hin and Cha-am: Hua Hin, Khao Takiab and Cha-am;
- Chonburi: Jomtien (Dong Tan) and Bang Saen;
- Koh Tao, Koh Lanta and Khao Lak: Chalok Ban Kao, Khlong Dao, Phra Ae and Khao Lak beach.
The list was renewed in 2020, and the department still runs smoke-free beach campaigns, so treat these beaches as no-smoking outside the marked spots. Karon, Kata, Chaweng, Lamai and Ao Nang weren’t on the official lists from 2018 or 2020. That doesn’t make them a free-for-all: check the signs, and take your butts with you.
Pattaya went further. Since July 2025, smoking has been banned on all of Pattaya’s beaches and the beachfront footpaths, with fines of up to 5,000 baht. The city runs patrols and takes complaints on its 1337 hotline.
National parks are smoke-free. That includes the island parks most tourists visit on boat trips: the Phi Phi islands and Maya Bay, the Similan and Surin islands, and Ang Thong near Koh Samui. The fine is up to 5,000 baht, and it applies to the whole park, not just the beaches.
Taxis, Grab and public transport
You can’t smoke on any public transport in Thailand: taxis, Grab and other ride-hailing cars, tuk-tuks, motorbike taxis, songthaews, minivans, buses, trains and passenger boats. In taxis, the ban applies even when the driver has no passengers.
The State Railway of Thailand tightened enforcement in May 2025. Fines of up to 5,000 baht now apply in the spaces between carriages too, where people used to smoke. On ferries, you may see people smoking on the open deck, but that doesn’t make it allowed.
Airports are smoke-free inside the terminals too, with designated areas mostly outside. We list them airport by airport in our guide to smoking areas at Thai airports.
Hotels and condos
In hotels, smoking is banned in lobbies, corridors and other common areas, and within 5 meters of entrances. Room rules vary by hotel, and many ban smoking in rooms. Cleaning fees of around 5,000 baht (about $146) are common, and some luxury hotels charge far more. If you smoke, ask for a room with a balcony and check the rules at check-in. We compare hotel fees and rules in our guide to vaping and smoking in hotel rooms.
In condos, the law covers only common areas like the lobby and corridors, but many buildings have stricter house rules, including for balconies.
Temples and tourist sights
Temples and religious sites are on the official no-smoking list, and smoking there is also seen as disrespectful. The same goes for palaces and museums, including the Grand Palace and Wat Pho. Public parks near them, like Sanam Luang, are no-smoking too.
Vapes and IQOS: the same rules, plus a bigger one
Heated tobacco like IQOS counts as smoking under Thai law, so all the no-smoking zones above apply to it too. No IQOS indoors, in taxis or on no-smoking beaches.
Vapes and heated tobacco also face a separate rule: they’re formally banned in Thailand, and importing or selling them is illegal. Away from the airport, enforcement is softer in practice, but customs applies the ban strictly, so it’s simpler to arrive with nothing to declare and get what you need delivered locally. We cover the details in our guides to vaping in Thailand and whether IQOS is legal in Thailand.
Smoking age and buying cigarettes
The legal age to buy tobacco in Thailand is 20. The law puts the burden on the seller: shops can’t sell to anyone younger and may ask for ID if you look young, so carry your passport or a photo of it.
Cigarettes are sold at 7-Eleven and other convenience stores, but not on display: packs sit in a closed cabinet behind the counter, and you ask for your brand by name. Our guide to cigarettes in Thailand covers brands, prices and how many you can bring in.
Fines at a glance
| Offense | Fine |
|---|---|
| Smoking in a no-smoking area (bars, taxis, parks, temples and more) | Up to 5,000 THB (about $146) |
| Dropping a cigarette butt | Up to 2,000 THB (about $58) |
| Smoking on Pattaya’s beaches or footpaths | Up to 5,000 THB (about $146) |
| Smoking in a national park | Up to 5,000 THB (about $146) |
| Smoking in a non-smoking hotel room | Hotel fee, often 5,000 THB (about $146) or more |
Most of these fines are easy to avoid: follow the signs, use the marked smoking spots and take your butts with you.
