Yes, you can chew gum in Thailand: we found no Thai law that bans it, unlike Singapore's well-known gum rules. What can get you fined is dropping the gum, a cigarette butt or any other rubbish in a public place, under Thailand's cleanliness law. Spitting in the street is frowned on too.
The law in question is the Act on the Maintenance of Cleanliness and Orderliness of the Country B.E. 2535 (1992), amended in B.E. 2560 (2017). It lets local authorities fine people who leave litter in streets, parks and other public places. How much they can fine is the part we could not confirm, and the reason is explained below.
Gum, litter and spitting: the short answer (October 2026)
- Chewing gum
- No ban found; buy and chew it freely
- Dropping gum, litter or butts
- Can be fined under the Cleanliness Act B.E. 2535 (amended 2017)
- Fine amount
- No official figure we could verify; reported amounts disagree
- Who enforces
- Local authorities, such as the city administration in Bangkok
- Smoking on 24 named beaches
- A separate, much heavier rule
- National parks
- Take all rubbish out with you; park rules apply
Chewing gum: legal to buy and chew
Visitors from Singapore may wonder, because gum sales are tightly controlled at home. Thailand has nothing similar that we could find. Gum is widely sold, including in convenience stores, and chewing it in the street is not an offence. The only places where you should not chew are where good manners ask for it: inside a temple, for example, as our guide to temple etiquette mentions in passing.
The legal problem starts when the gum leaves your mouth. A piece stuck to a pavement, a bench or the floor of a BTS station is litter, and litter is what the cleanliness law is about. Wrap it in paper and put it in a bin.
What the cleanliness law covers
The Cleanliness Act covers the everyday things that make a street dirty: throwing or leaving rubbish in public places and dumping waste, for example in Bangkok's canals. Whether spitting has its own penalty under the Act is something we could not check in the text. The 2017 amendment updated the 1992 Act. Enforcement is local, which in practice means city or municipal officers, not the national police.
We tried to read the fine amounts in the Royal Gazette and the official legal database. Both were behind a bot check we could not pass. Thai news reports quote different maximums for different offences, and English-language websites repeat figures from 2,000 baht to 100,000 baht without citing the text. Rather than print a number we cannot stand behind, we leave it out. Assume that a fine is possible wherever you are, and if you need the exact amount, ask the local district office.
Ignore the fine figures on blogs and in AI answers. The amounts for littering in Thailand that circulate online do not agree with each other, and none of the ones we checked cited the Act's actual text. If you need the real figure, ask the local district office or check the Royal Gazette.
Cigarette butts and the beach smoking ban
A cigarette butt flicked onto the pavement is litter like any other. On some beaches, though, the problem starts before the butt hits the sand: since 1 February 2018, smoking itself has been banned on 24 named beaches, including Patong, Pattaya Beach and Hua Hin, with penalties of up to 100,000 baht and/or a year in prison. Our page on smoking rules in Thailand covers where you may and may not light up.
Where smoking is allowed, use the ashtray in the smoking area. Butts in the sand are the most common rubbish on many beaches, and a pocket ashtray costs very little.
Beaches and marine parks
Many popular beaches sit inside marine national parks, where park rules apply on top of the cleanliness law. When the Department of National Parks reaffirmed its ban on coral-harming sunscreens in October 2025, it also reminded visitors not to throw rubbish into the sea and to follow park officers' instructions. Boats to the Similan Islands and other marine parks expect you to bring every wrapper and bottle back.
Shells, sand and coral are a separate matter: taking them is not littering but removal, and our guide to what you can't take home explains why it can cost more than any littering fine.
National parks on land
Land parks have written rules. Khao Yai's official list, for example, asks visitors to take their litter home, bans polystyrene and toxic waste, bans fires and allows smoking only in marked areas. Other parks use similar rules, and rangers can enforce them. Pack a bag for your own rubbish before a hike in Khao Sok or any other park, because bins on the trails are rare.
Spitting and the rest of street manners
Whatever the exact legal position, spitting in the street is something many Thais consider crude. If you need to spit, use a tissue and a bin. The same goes for dropping food wrappers from a market stall or leaving bottles on a wall.
Our article on what never to do in Thailand puts littering in the wider picture. If you live here, our guide to rubbish and recycling explains collection, fees and how to report dumped waste. For the beach dress question that often comes up next, see topless and shirtless rules.
Frequently asked questions
Is chewing gum banned in Thailand like in Singapore?
No. We found no Thai law that bans buying or chewing gum, and it is widely sold in convenience stores. Throwing used gum on the ground is a different matter: that counts as litter under the cleanliness law.
How much is the littering fine in Thailand?
We could not verify an official figure. The cleanliness law allows fines, but the statute text was not reachable and the amounts reported in the press and online disagree. Assume a fine is possible and ask the local district office for the exact amount.
Can you be fined for dropping a cigarette butt in Thailand?
Yes, a butt on the ground is litter under the cleanliness law. On the 24 beaches covered by the beach smoking ban, smoking itself is an offence with penalties of up to 100,000 baht and/or a year in prison.
