International Cooperation In Drug Prosecutions
1. Introduction
International cooperation in drug prosecutions is essential because drug trafficking is often transnational. Cooperation occurs through:
Extradition treaties – transferring suspects to the country where prosecution is pending.
Mutual Legal Assistance (MLA) – sharing evidence, witness statements, and investigation reports.
Joint investigations – coordinated operations between law enforcement agencies across countries.
United Nations Conventions – such as the 1961 Single Convention on Narcotic Drugs, 1971 Convention on Psychotropic Substances, and 1988 UN Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances.
Criminal liability for drug offenses can be enforced across borders when countries cooperate, ensuring that traffickers cannot exploit jurisdictional gaps.
