These goals are pursued through three primary functions: research, guidance and support to governments in the adoption and implementation of various crime-, drug-, terrorism-, and corruption-related conventions, treaties and protocols, as well as technical/financial assistance to said governments to face their respective situations and challenges in these fields. The office aims long-term to better equip governments to handle drug-, crime-, terrorism-, and corruption-related issues, to maximise knowledge on these issues among governmental institutions and agencies, and also to maximise awareness of said matters in public opinion, globally, nationally and at community level. Approximately 90% of the Office's funding comes from voluntary contributions, mainly from governments. These are the main themes that UNODC deals with: alternative development, anti-corruption, criminal justice, prison reform and crime prevention, drug prevention, treatment and care, HIV and AIDS, human trafficking and migrant smuggling, money laundering, organized crime, piracy, terrorism prevention.
