Conventions on drugs

The three major international drug control treaties are mutually supportive and complementary. An important purpose of the 1961 Single Convention on Narcotic Drugs and the 1971 Convention on Psychotropic Substances codify internationally applicable control measures in order to ensure the availability of narcotic drugs and psychotropic substances for medical and scientific purposes, and to prevent their diversion into illicit channels and include general provisions on trafficking and drug use. The 1988 United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances significantly reinforced the obligation of countries to apply criminal sanctions to combat all the aspects of illicit production, possession and trafficking of drugs.
