The United Nations Office on Drugs and Crime (UNODC) was established in 1997 to help the UN address issues related to drug trafficking, crime prevention, terrorism, and corruption. It employs around 500 people worldwide and is headquartered in Vienna, with 21 field offices. The agency aims to help governments handle drug, crime, terrorism and corruption issues through research, guidance, and technical/financial assistance. Approximately 90% of its funding comes from voluntary government contributions.
