The following Singapore laws are to be strictly observed.

Drugs

• You must not consume or supply illegal drugs.
• The death penalty is mandatory for those convicted of trafficking, manufacturing, importing or exporting more than 15g of heroin, 30g of morphine, 30g of cocaine, 500g of cannabis, 200g of cannabis resin and 1.2kg of opium.
• Possessing these quantities is considered evidence of trafficking.  This means, if you possess these quantities, you are deemed to be a trafficker and therefore subject to the death penalty.
• For unauthorised consumption, there is a maximum of 10 years’ jail or fine of S$20,000, or both.

Littering

• Singapore has strict laws on littering of any kind.
• First-time offenders face a fine of up to S$1,000.
• Repeat offenders will be fined up to S$2,000 and subject to Corrective Work Order (CWO).
• The CWO requires litterbugs to spend a few hours cleaning a public place, for example, picking up litter in a park.  They are made to wear bright jackets, and sometimes, the local media are invited to cover the public spectacle.  So please think twice about tossing a scrap paper or cigarette butts on the roadside.

Smoking

• Smoking is not allowed in all public indoor places and most outdoor places, unless otherwise mentioned. Eg; buses, MRT, taxis, lifts, theatres, cinemas, government offices, and in air-conditioned restaurants and shopping centers.
• Smoking is also not permitted at all nightspots unless within approved smoking zones.
• Offenders face a maximum fine of S$1,000. In addition, smokers who dispose their cigarette butts indiscriminately will be fined SGD$200.00.
