Smoking and vaping in Bangkok: nobody banned “public places”, they published a list

Thailand’s smoking law does not work by category. A minister designates specific kinds of place, and a notification in force since February 2019 does the designating — in four different geometries, one of which draws a five-metre bubble around every door, window and air vent. Bus stops are on the list. So are cash machines, car parks, lifts, night markets and the corridor outside your flat. And the fine everyone quotes stopped being a criminal fine in June 2023.

The list is the law

English-language guidance on smoking in Thailand tends to arrive as a mood: they’re strict, there are big fines, be careful in public. That is not a rule you can act on, and it is not how the statute works.

Section 41 of the Tobacco Products Control Act B.E. 2560 gives the Minister of Public Health, on the recommendation of the national committee, the power to declare types or names of public place, workplace and vehicle to be smoke-free, in whole or in part — and to permit a smoking area within one. Section 42 then says, in nine words of Thai, that no person shall smoke in a smoke-free zone except in a smoking area designated under section 41.

So the Act itself designates nothing. Everything depends on a notification, and the operative one was signed on 24 September 2018, published in the Royal Gazette on 5 November 2018 and came into force ninety days later, on 3 February 2019. It is eight pages long, it is entirely in Thai, and it is the single most useful document in this whole area — because rather than gesturing at “public places” it enumerates them, and it attaches a different geometry to different groups.

That last part is what nobody explains. Four clauses, four shapes.

Clause 3: the whole site, plus five metres from the entrance

Clinics and hospitals, including veterinary ones; pre-school childcare; schools below tertiary level; tutoring establishments and the places that teach sport, music, singing, performance, martial arts, art and languages; child welfare homes; playgrounds. For these the zone is everything within the premises, indoors and outdoors, fenced or not — and five metres out from the entrance. The notification even tells you how to measure it: where there is a clear entrance, five metres outward from both of its edges; where the place has no clear entrance, or can be entered from any direction, five metres from whichever main entrance the operator designates.

Clause 4: the whole site, no buffer — and this is the long one

This clause is where Bangkok life mostly happens. It covers massage, herbal-steam and spa premises; vocational training centres, learning parks, galleries, museums and public libraries; sports grounds, spectator stands, gyms, yoga studios, driving ranges and swimming pools; petrol and gas stations; banks and cash machines; air-conditioned eateries; beauty salons; car and motorcycle workshops; car parks, including park-and-ride; shops selling consumer goods, and pharmacies; barbers, tailors, laundries and self-service laundrettes; cinemas and theatres; internet and game shops; karaoke and licensed entertainment venues; places of worship; welfare homes; animal shelters; parks, zoos, amusement parks and water parks; exhibition, conference and training venues; banquet venues; markets, flea markets, floating markets and walking streets; public toilets; public telephones; and the passenger lifts of every kind of public place.

The same clause takes in public vehicles while in service, whether or not carrying a passenger — buses, taxis, motorbike taxis and three-wheelers, minivans, school and staff transport, horse-drawn carriages, cable cars, passenger boats and ferries, ambulances and fire engines, trains, the elevated and underground railways, trams, aircraft. And it takes in the waiting points that sit outside a terminal: piers, the pick-up points used by minivans, taxis, songthaews, three-wheelers and motorbikes, and — the detail that will surprise almost everyone — a bus stop together with a radius of three metres from the pole, or from the outer edge of the shelter.

Clause 5: the whole site, but an outdoor smoking area is allowed

Three entries only: universities; government offices, state enterprises and other state bodies; and airports. This is the clause that explains the smoking points you see at Suvarnabhumi and outside ministries. Note the qualifier the notification attaches: the smoking area must be outside the building.

Clause 6: only the named part, plus five metres from its openings

Here the zone is not the whole site, and the buffer is measured differently — five metres from the designated area itself, or from its doors, windows, entrances, exits, ducts or air vents. It covers the interior and roof deck of shopping centres, private workplaces, factories, golf courses, historical and national parks, botanical gardens, open-air museums and memorials. It covers the interior, roofed area and platform of bus terminals, railway stations, BTS and MRT stations, tram stations and passenger piers. It covers the lobbies, shared rooms and internal corridors of condominiums, of rented rooms, dormitories, mansions and apartments, and of hotels, resorts and homestays. And it covers the serving area of an eatery without air conditioning.

The fine is real, and it is no longer a crime

Section 67 sets the penalty for smoking in a smoke-free zone at a fine of up to 5,000 baht. That figure is quoted accurately in almost every English guide, and every one of them we saw calls it a criminal fine. As of the middle of 2023, it isn’t one.

The Act on Administrative Fines B.E. 2565, published on 25 October 2022, converted criminal offences punishable by fine only under the statutes listed in its first schedule into administrative offences — ความผิดทางพินัย — with effect 365 days after publication, which is 22 June 2023. Section 67 is fine-only, so it converts. So do section 68 and section 70. Section 71, which punishes obstructing an officer and carries imprisonment, does not.

The corroboration that the tobacco Act is genuinely inside this system is on the Department of Disease Control’s own law page: a Ministry of Public Health notification of B.E. 2566 designating the state officials empowered to impose administrative fines under the Tobacco Products Control Act B.E. 2560. Ministries do not appoint officers to impose a kind of penalty that does not apply to them.

This is the same mechanism that we described in the context of Bangkok’s pet rules, where a much-quoted 25,000-baht penalty turns out not to be a criminal fine either. The practical differences are worth stating plainly: an administrative penalty is imposed by a designated official rather than obtained through a criminal prosecution, the person’s ability to pay is a relevant consideration in that system, and the outcome is not a criminal record.

One thing we could not settle, and would rather flag than smooth over. At least one government-linked summary of the tobacco rules states the smoker’s administrative fine as not exceeding 3,000 baht rather than 5,000. Three thousand is the figure section 70 attaches to a quite different offence — an operator’s failure to publicise and intervene — so the likeliest explanation is that the summary crossed two rows. But we cannot rule out that a lower tariff has been set by regulation inside the administrative-fine system, and we did not find the schedule. The statutory ceiling we read in the Gazette text is 5,000.

The venue is in far more trouble than you are

Look at the penalty structure as a whole and the Act’s real strategy becomes visible. It is not primarily aimed at smokers.

Section 68 exposes the operator of a designated place to a fine of up to 50,000 baht for failing to do what section 43 requires: display a clear sign marking the zone, and keep it free of equipment or facilities for smoking. That is ten times the smoker’s exposure, for a paperwork-and-ashtrays offence. Section 70 adds up to 3,000 baht for failing the section 46 duty to publicise the zone and to control, dissuade or otherwise act to stop people smoking in it.

And then section 46 does something unusual and rather fair. Its second paragraph provides that where someone does smoke in the zone, if the operator has reasonably done the things paragraph one requires, the operator commits no offence. It is an express statutory safe harbour, and it explains a piece of Bangkok behaviour that otherwise reads as officiousness: the reason a member of staff will walk over and ask you to put it out, promptly and without much negotiation, is that their doing so is the thing that protects the business.

Why the cigarettes are behind a shutter

Two sections explain the visual character of Thai tobacco retail. Section 30 bans advertising and marketing communication of tobacco products outright. Section 31 bans displaying the name or mark of a tobacco product, or of its producer or importer, for the purpose of advertising. Between them a shop may sell the thing but may not show it, which is why the cabinet behind the till in a convenience store is covered and why you have to name what you want.

Section 27 fills in the rest: no vending machines, no selling by electronic media or over a computer network, no selling away from the licensed premises, no giving away or exchanging, no showing a price reduction at the point of sale, no giving tobacco as a premium with other goods, and no hawking it. Section 26 sets the purchase age at 20 — raised from 18 by this Act — and requires the seller to ask for identification if age is in doubt. Section 29 bans sale altogether at temples and places of worship, at health facilities and pharmacies, at schools, and in public parks, zoos and amusement parks.

E-cigarettes: three statutes, and none of them says “possession”

Now the part that generates the most confusion and the worst advice, and it is worth going slowly, because the confusion is structural rather than accidental. Thailand does not regulate e-cigarettes under the tobacco Act. It reaches them through three unrelated instruments, and the gaps between those instruments are exactly where the arguments happen.

• Importing is prohibited. A Ministry of Commerce notification of 12 December 2014 made baraku and electronic baraku or e-cigarettes goods prohibited from import into the kingdom. Breaching that runs through the Export and Import Act B.E. 2522, section 20 — up to ten years, or a fine of five times the value of the goods, or both, plus forfeiture — and through the Customs Act B.E. 2560, section 244, at up to ten years or 500,000 baht or both.
• Selling is banned. Order 9/2558 of the Consumer Protection Board, dated 28 January 2015, prohibits the sale of, and the provision of services involving, baraku, e-baraku and e-cigarettes and their liquids. The penalty runs through the Consumer Protection Act at up to three years or 600,000 baht or both.
• Having one is where it gets interesting. There is no Thai statute that creates an offence of possessing an e-cigarette. What is charged instead is section 246 of the Customs Act: helping to conceal, dispose of or carry away, or buying, taking in pawn, or otherwise receiving, goods that the person knows to be connected with a customs offence — up to five years, or four times the duty-paid value, or both.

That third one is not a technicality. It is a receiving-smuggled-goods offence with a knowledge element attached, and it exists only because of the import prohibition: since no e-cigarette can lawfully have entered Thailand, any device in the country is by definition goods that arrived in breach of a prohibition. Thai legal commentary makes exactly this distinction — importing and selling are clear-cut, possession is คลุมเครือ, ambiguous — and it is the best explanation for why people report such wildly different outcomes from encounters that sound identical.

We should be equally clear about what that does not mean. It does not mean having a vape in Bangkok is safe, or that the ambiguity is a defence you would want to be relying on at a police station at midnight. A nationwide crackdown ordered at the start of 2025 with a thirty-day deadline produced, on police figures reported at the time, 690 people arrested across 666 cases, with roughly 455,000 items seized and valued at over 41 million baht. A parliamentary special committee has reported on whether to regulate rather than prohibit, and nothing has been enacted.

One more overlap that catches people: vaping inside a smoke-free zone is also the ordinary section 42 offence, because the 2560 Act’s definition of a tobacco product reaches e-cigarettes. So the person vaping on a BTS platform is exposed under two entirely separate bodies of law at once, for two different reasons.

If you have just arrived

• Assume you are inside a zone unless you are on the street or at home. In built-up Bangkok that is very nearly true, and it is a better working rule than trying to recall a list of forty-odd categories.
• Learn three specific ones, because they catch everybody: the bus stop and its three metres, the car park, and the passenger lift.
• Look for the sign. The operator is legally required to display one, at ten times your own exposure. Its presence tells you where you are; its absence tells you something about the venue rather than about the law.
• If a member of staff asks you to stop, that is them using their safe harbour. There is nothing to negotiate and no discretion for them to exercise.
• Do not bring a vape. Whatever the correct academic view of section 246, the import prohibition is unambiguous and the device cannot lawfully cross the border in your bag.
• 200 cigarettes, or 250 grams. Above that, declare it or surrender it at the customs point rather than walking through — and note that a duty-free purchase made on arrival is still an import.

Questions people actually ask

Can I smoke on the pavement?

The pavement as such is not designated, so as a general matter yes — but in a dense part of Bangkok that general matter gets eaten by the buffers. You can be on a public footpath and still be inside a zone: within five metres of a hospital or school entrance, within three metres of a bus stop pole or shelter edge, within five metres of the serving area of an open-fronted eatery, or within five metres of the door, window or vent of a designated part of a building. On a two-metre Bangkok pavement, several of those can overlap at once. Standing in the street is not a defence; being outside every buffer is.

Is there anywhere left to smoke indoors?

Only in a smoking area designated under section 41 paragraph two, which is the exception section 42 preserves. Clause 5 is the clause that permits one for universities, government offices and airports — and it says the area must be outside the building. Where a designated smoking area does exist, section 44 sets conditions for it: it must be clearly marked and must not sit in the entrance or exit area of the place. We are describing what the instruments allow, not surveying what individual venues have actually built.

My condo has a no-smoking rule. Is that the same thing?

No, and the distinction matters when you want something enforced. The notification makes the lobby, shared rooms and internal corridors of a condominium a smoke-free zone under clause 6, with five metres measured from those areas and their openings; that is public law and the officials empowered to impose the administrative fine stand behind it. A building regulation about balconies or units is private law, made by the juristic person, and its enforcement route is the one we set out in our guide to pet rules — ultimately an ordinary civil claim rather than a fine. Working out which of the two you are dealing with is the first step in getting anywhere.

Are heated tobacco products treated as cigarettes or as vapes?

We did not establish it and will not guess. Heated products sit awkwardly between the tobacco Act, which regulates tobacco products, and the 2014 import prohibition, which names baraku and electronic baraku or e-cigarettes. Which side a particular device falls on is exactly the kind of question that is decided by a classification we did not read, and getting it wrong in either direction would be worse than saying so.

Someone told me it is illegal to smoke in your own car. Is it?

Not on the basis of anything in this notification, as far as we can see. Clause 4 covers public vehicles while in service, and it does so generously — buses, taxis, motorbike taxis, minivans, school and staff transport, boats, trains, aircraft — but a private car used privately is not in that list. What is in the list, and does surprise people, is that a taxi is smoke-free whether or not it currently has a passenger in it.

How is any of this actually enforced?

Through designated officers with powers of entry during working hours under the Act’s enforcement chapter, and now through the administrative-fine machinery rather than through criminal prosecution for the fine-only offences. The visible enforcement in practice is done by venues policing themselves, for the reason the safe harbour gives them. We have not tried to measure how often the smoker’s fine is actually imposed and we would not trust an anecdotal answer, so we are describing the rules rather than a hit rate.

Why do the English-language sources get this so consistently wrong?

Because the useful document is a Thai-language notification of place names and measured distances that nobody translates, while the quotable one is a single number in a penalty section. So the number travels — five thousand baht — and the list, the geometry, the ten-to-one asymmetry and the 2023 change of legal character all stay behind. It is the same pattern we keep running into on this desk: the headline crosses the language barrier, and the conditions that decide how it applies do not.
