Strict does not mean difficult
Singapore has a reputation for strict laws, but ordinary visitors are unlikely to have problems if they behave as they would in any well-run city. The useful approach is to understand the handful of rules that differ from home, especially around vaping, controlled goods, drugs, smoking and public transport, instead of worrying about internet lists of obscure offences.
Penalties and enforcement policies can change. For anything involving controlled substances, medicines or prohibited imports, treat current Singapore Government guidance as the authority rather than an old travel blog.
Do not bring a vape
E-vaporisers are prohibited in Singapore. Purchase, possession and use are illegal, and border agencies actively enforce the rule. This applies even if vaping is legal where you live or the device is for personal use. The safest visitor rule is straightforward: do not pack the device, pods, cartridges or related components.
Singapore strengthened its vaping enforcement framework again in 2025–26, including much tougher consequences for products containing etomidate and stronger checkpoint action. It is not a rule worth testing on arrival.
Chewing gum: the real rule
The famous “gum ban” is mainly an import and sale restriction, not a reason to panic because you once chewed gum. Singapore Customs lists chewing gum as prohibited for import, with exceptions for approved oral-dental and medicinal gum. Visitors should therefore avoid bringing ordinary chewing gum into Singapore rather than relying on the myth that “a small personal amount is always fine”.
Drug laws are genuinely severe
Singapore’s drug laws are not a tourist curiosity. Importation, trafficking and possession of controlled drugs can carry extremely serious penalties. Do not carry recreational drugs, cannabis products or someone else’s medication across the border. If you travel with prescription medicine that may contain controlled substances, check Health Sciences Authority requirements before departure and carry the correct documentation.
Smoking is restricted to permitted places
Smoking is prohibited in many indoor and outdoor public places. Look for designated smoking areas and local signage rather than assuming that an open-air location is automatically permitted. Hotels also set their own smoking-room policies. Vaping is not an alternative — it is prohibited outright.
Eating, drinking and behaviour on public transport
The MRT and buses are clean partly because rules are enforced. Do not eat or drink in the rail system, and follow station signs about prohibited items and behaviour. Keep doors clear, queue sensibly and give priority seats and accessible spaces to passengers who need them.
Durian is famously restricted on parts of the public-transport network because of its smell; the practical lesson is broader: if station signage says an item or activity is prohibited, take it seriously.
Littering and cleanliness
Do not drop rubbish, cigarette butts or other waste. Singapore uses fines and corrective measures to discourage littering, and repeat offending can bring more serious consequences. Bins are common enough that there is no need to gamble on “just this once”.
Road crossings and jaywalking
Use pedestrian crossings, overhead bridges and underpasses where provided, and obey the pedestrian signals. Singapore traffic can move quickly even when streets look orderly. Apart from enforcement, this is simply the safer habit in a left-driving city where visitors may instinctively look the wrong way.
Alcohol and nightlife
Singapore controls drinking in public places during specified hours and has additional restrictions in designated Liquor Control Zones. Licensed bars, restaurants and hotels operate under their own permitted hours. If you are heading out late, drink at licensed venues and do not assume you can continue drinking from takeaway containers anywhere on the street after closing.
Photography, privacy and sensitive places
Most tourist photography is uncomplicated, but respect “no photography” signs at security-sensitive locations, museums, places of worship and private premises. Do not photograph people intrusively. Drones are separately regulated and may require permits depending on where and how you fly; casual assumptions based on another country’s rules can get you into trouble.
Public behaviour
Harassment, threatening conduct, vandalism and public disorder are obviously poor ideas anywhere, but Singapore’s orderly feel should not be mistaken for an absence of enforcement. Treat staff, drivers and other travellers respectfully and follow directions from police, security officers and transport staff.
Before you fly: check the things that matter
- Leave vaping products and recreational drugs at home.
- Check prescription medicine requirements with HSA if your medicine may be controlled.
- Check Singapore Customs for unusual food, plant, animal or controlled goods.
- Use designated smoking areas only.
- Do not eat or drink on the MRT.
- Use proper pedestrian crossings and obey local signs.
- Follow venue-specific rules for photography, dress and security.
You do not need to memorise Singapore’s statute book. Avoid the genuinely prohibited items, respect signs and public-space rules, and the legal side of a normal holiday is usually uneventful.
