What's Illegal inSingapore?

The single thing worth knowing first: Death penalty for drugs. Chewing gum banned. Massive fines for minor offenses. It is the kind of rule that looks minor at home and becomes a serious problem at the border or in public, which is exactly why it tops this page.

Within everyday activities and public behavior, Singapore treats Eating on MRT, Drinking on MRT, and Durian on MRT, among others, as off-limits. Carrying or doing any of these can mean confiscation, fines, or detention depending on the case — and a foreign prescription, habit, or "I didn't know" rarely helps once you are stopped. Each entry below links to the official source it is checked against, with the verified ones marked.

Two things travelers regularly get wrong about Singapore: Chewing gum is not banned to chew but cannot be sold or imported in commercial quantities, with therapeutic gum the only exception; and Vape devices are illegal to possess or carry in transit, even when sealed in checked baggage. Assumptions like these are how otherwise careful visitors end up in trouble, so it is worth checking the specifics rather than guessing.

One important caveat: Drug testing on arrival can detect substances consumed in another country and is treated as consumption inside Singapore. Laws and their enforcement can shift between regions and over time, so treat this page as a sourced starting point and confirm anything borderline against the official links before you rely on it.
