on 19 February 1925. It went into effect on 25 September 1928, and was registered in ''League of Nations Treaty Series'' on the same day. It introduced a statistical control system to be supervised by a Permanent Central Opium Board, a body partly linked to the

Permanent Central Opium Board

The 1925 Convention provided for the setting up of a Permanent Central Opium Board (PCOB). It started operating in 1928. Although a treaty-mandated body, theoretically independent from the

, it became partially-integrated into the structure of the League. The PCOB was first known as the ''Permanent Central Opium Board,'' then as the ''Permanent Central Narcotics Board''. It is sometimes referred to as ''Permanent Central Board''. In 1931 the Board was supplemented by the creation of another organ under the " Limitation Convention": the Drug Supervisory Body ("''Organe de Contrôle''") which, together with the PCOB, was eventually merged onto the International Narcotics Control Board in 1968.

and other countries objected to this language, citing social and religious customs and the prevalence of wild-growing cannabis plants that would make it difficult to enforce. A compromise was made that banned exportation of ''Indian hemp'' to countries that have prohibited its use, and requiring importing countries to issue certificates approving the importation and stating that the shipment was required "exclusively for medical or scientific purposes." It also required Parties to "exercise an effective control of such a nature as to prevent the illicit international traffic in Indian hemp and especially in the resin." These restrictions still left considerable leeway for countries to allow production, internal trade, and use of cannabis for recreational purposes.
