The Misuse of Drugs Act 1973 is a statute of the Parliament of Singapore that enables authorities to prosecute offenders for crimes involving illegal drugs. The law is designed specifically to grant the Government of Singapore, through its agencies such as the Central Narcotics Bureau, enforcement powers to combat offences such as the trafficking, importation or exportation, possession, and consumption of controlled drugs.^[1]

Despite its close proximity to the major drug producing areas of the Golden Triangle, in the late 1960s Singapore had relatively little hard drug use, with an estimated 8,000 local opium addicts out of a total population of just over 2 million people. These regular users tended to be older Chinese Singaporean men, whose activities the authorities often turned a blind eye due to the younger generation of Singaporeans not picking up the same habits. MX pills were freely available and widely abused a recreational drug, while cannabis smoking became more widespread as the hippie culture became popular. However, in the early 1970s a sudden heroin epidemic swept through the city state, addicting over 3% of the young male population within a couple of years, with virtually all of them chasing the dragon with low quality (less than 40% pure) Heroin Number 3.^[2][3]

As Singapore is a small island nation with no exportable natural resources, its economic model at the time was based on added-value activities (such as factory work or sea-bourne cargo logistics) from an industrious and efficient society, which the possibility of a large percentage of the population becoming unproductive due to drug addiction posed an enormous economic threat. The Government of Singapore responded with a zero tolerance policy regarding the abuse of all types of drugs, aiming to rapidly contain the sudden heroin epidemic via new laws that proscribed harsh punishments for both traffickers (such as the death penalty) and consumers (including caning) alike.^[4][5][6]

The Misuse of Drugs Act 1973 classifies narcotic 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 statute's penal provisions are severe by most nations' standards, providing for long terms of imprisonment, caning, and capital punishment.

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.

Section 17 of the Misuse of Drugs Act^[8] lists the amount of controlled drugs beyond which, the person who carries them shall be presumed to possess them for the purpose of drug trafficking unless proven otherwise:

The possession, consumption, manufacturing, import, export, or trafficking of these and other controlled drugs in any amount is illegal. Persons caught with less than the Mandatory Death Penalty amounts of these controlled substances face penalties ranging from caning^[16] (up to 24 strokes) to life in prison. Pursuant to a law change in 2009, cannabis (marijuana) and marijuana mixtures (diluted with other substances) are treated the same under Singapore law—the presumed intent is trafficking.
