Misuse of Drugs Act Singapore

Misuse of Drugs Act Singapore

The Misuse of Drugs Act (MDA) governs drug related offences in Singapore and consists of 7 parts (Part I – Part VII) with 59 sections and 5 Schedules (First Schedule – Fifth Schedule). [The MDA is accessible at https://sso.agc.gov.sg/Act/MDA1973].

The Misuse of Drugs Act penalises both the drug trafficker (seller) and the drug consumer (buyer). It lays down offences of manufacturing, trafficking, importing or exporting, possessing or consuming of the controlled drugs (sections 5-7 of MDA).

A Singapore citizen or permanent resident of Singapore who is found (by a urine test) to have consumed controlled drugs outside of Singapore, he or she will be taken to have consumed the controlled drugs in Singapore and as a result, he or she has committed an offence under the Misuse of Drugs Act. He or she will receive the punishment as stated under the MDA (section 8A of MDA).

Possession of any pipes or utensils for smoking or for the administration of drugs is illegal as well (section 9 of MDA).

MDA forbids the cultivation of any plant from the genus of cannabis, or any plant from which cocaine can be extracted (section 10 of MDA).

MDA categorises the drugs into 3 classes i.e. Class A, Class B and Class C (First schedule of the MDA lists down all 3 classes of controlled drugs).

Presumption of Drug Possession (Sections 17-22 of MDA)

Any person who possesses anything that containing a controlled drug is presumed to be in possession of the drug unless the person has the burden to prove otherwise, for instance, he or she was unaware that he or she was in possession of the substances. The police is not required to produce a search warrant to enter into any premises for drugs raid.

Presumption of Trafficking (Section 17 of MDA)

If any person has in his or her possession more than a certain weight of drugs (as specified in the MDA), it is presumed that the drugs are for trafficking purpose. The accused has the burden to prove that his possession of the drugs is not for trafficking purpose.
