The United Nations Drug Control Conventions are a series of international treaties aimed at combating drug abuse and trafficking. Established in the 20th century, these conventions provide a legal framework for countries to regulate and control the production, distribution, and use of narcotic drugs and psychotropic substances. The main treaties include the Single Convention on Narcotic Drugs of 1961, the Convention on Psychotropic Substances of 1971, and the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances of 1988. These conventions promote international cooperation and encourage countries to adopt effective drug control policies. They also emphasize the importance of balancing drug control with public health considerations, aiming to reduce drug-related harm while ensuring access to necessary medications. By establishing guidelines and obligations, the conventions seek to create a unified global approach to drug-related issues.
