IMPORTANT NOTICE For Singapore drug controlled

The Misuse of Drugs Act is a drug control law in Singapore classifying substances into three categories, Classes A, B, and C. Section 44 provides that "The Minister may, by an order published in the Gazette" add, remove, or transfer drugs among the classes.

The law creates a presumption of trafficking for certain threshold amounts, e.g. 30 grams of cannabis. It also creates a presumption that a person possesses drugs if he possesses the keys to a premises containing the drugs, and that "Any person found in or escaping from any place or premises which is proved or presumed to be used for the purpose of smoking or administering a controlled drug shall, until the contrary is proved, be presumed to have been smoking or administering a controlled drug in that place or premises." Thus, one runs the risk of arrest for drug use by simply being in the company of drug users. The law also allows officers to search premises and individuals, without a search warrant, if he "reasonably suspects that there is to be found a controlled drug or article liable to seizure"

Moreover, Section 31 allows officers to demand urinalysis of suspected drug offenders while section 8A prohibits any citizen or permanent resident of Singapore to use any prohibited drug outside of the country, and if found guilty to be punished as if they committed that act within the country.
