About CNB50


As early as 1970, the menace of drug addiction was a concern in Singapore. In response to this, the Central Narcotics Bureau (CNB) was set up as a new and dedicated agency to fight the drug menace.

Established in 1971, CNB serves as the primary drug enforcement agency with a clear and focused mandate – to keep Singapore safe from the harms of drugs and inhalants.

In 2021, CNB celebrates its 50th anniversary in keeping Singapore drug-free, where everyone can live, work and play safely.

The CNB50 logo was designed to commemorate CNB’s 50th anniversary. It incorporates distinctive elements of CNB’s identity, including the CNB crest and the Anti-Drug Ribbon, a symbol of the anti-drug cause and Singapore’s united stand against drugs.


CNB50 Stories - Our Past and Present


The name ‘Central Narcotics Bureau’ (CNB) was coined by the then Permanent Secretary of Home Affairs, the late Mr Tay Seow Huah, and CNB’s first Director, the late Mr John Hanam. The name signified that drug enforcement was now centralised into one department, and also enabled overseas enforcement agencies to recognise CNB.
