The Central Narcotics Bureau (CNB) is celebrating its 50th anniversary in 2021. Formed in November 1971, with a small force of fewer than 20 officers, CNB was tasked with fighting the scourge of drugs, to make Singapore a safer place without drugs. Over the years, CNB has evolved from a predominantly enforcement agency to an agency that focuses on Enforcement, Education and Engagement to realise its vision for a drug-free Singapore. This set of stamps is released as part of CNB's 50th anniversary celebration. It features anti-drug messages to serve as a reminder of CNB's commitment towards a Singapore without drugs, where everyone can live, work and play safely.
