The Convention for Limiting the Manufacture and Regulating the Distribution of Narcotic Drugs was a drug control treaty promulgated in Geneva on 13 July 1931 that entered into force on 9 July 1933.
It established two groups of drugs.
Group I consisted of:
Group II consisted of:
Group I was subject to stricter regulations than Group II. For instance, in estimating the amount of drugs needed for medical and scientific needs, the margin allowed for demand fluctuations was wider for Group II drugs than for Group I drugs. Also, in certain reports, a summary statement would be sufficient for matters related to Group II drugs. The establishment of these rudimentary groups foreshadowed the development of the drug scheduling system that exists today. Both the 1961 Single Convention on Narcotic Drugs and the 1971 Convention on Psychotropic Substances have schedules of controlled substances. The 1988 United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances has two tables of controlled chemicals.
The 1931 convention's scope was broadened considerably by the 1948 . The Convention was superseded by the 1961 Single Convention on Narcotic Drugs.
The conference was held in Geneva on or about 27 May 1931.
