30 March 1961

The Single Convention on Narcotic Drugs is signed in New York City.

The Single Convention on Narcotic Drugs is an international treaty aimed at combating drug abuse and trafficking. It was signed in New York City on March 30, 1961, and it came into force on December 13, 1964. The convention was adopted by the United Nations and remains one of the most important international treaties concerning drug control.

Regulating the production, distribution, and use of narcotic drugs to ensure their availability for medical and scientific purposes while preventing their abuse.
Establishing measures for international cooperation in controlling the cultivation of plants that can be used to produce narcotics.
Promoting research and development of alternative substances to narcotic drugs.
Implementing measures to prevent the diversion of narcotics from legal channels to illegal markets.

The convention classifies narcotic drugs into four schedules based on their medical use and potential for abuse, with stricter controls imposed on those deemed to have a higher risk of abuse and limited medical utility.

The Single Convention has been amended several times to adapt to changing circumstances and to address emerging challenges in drug control. It serves as the cornerstone of the international drug control system, forming the basis for subsequent treaties and agreements aimed at combating drug abuse and trafficking worldwide
