The present Study is concerned exclusively with the supply and demand of opiates for medical and scientific needs; consequently whenever reference is made to cultivation, production, trade etc, we are concerned exclusively with the licit aspects of these activities unless the context indicates otherwise. 2. The Study consists of ten chapters together with statistical tables included as Annex A. The first chapter deals with definitions and certain introductory questions which will facilitate an examination of the technical chapters which relate successively to demand, production of raw materials, manufacture, international trade, stocks and the balance between the supply and the demand of opiates (Chapters II to VII). These chapters are termed technical because they consist mainly of an analysis of the statistical data. The Board has reserved for certain paragraphs of Chapter VIII, Legal Considerations; Chapter IX, Economic Considerations; and of course Chapter X, Conclusions and Recommendations, the expression of some opinions. For purposes of reference, Annex A which includes the basic data is followed by Annex B consisting of the resolutions adopted by United Nations organs related to the subject of the Study. 3. Finally we have left the statement of the exact situation in each producing country to the country itself, and statements by those countries wishing to contribute are included in Annex C. 4. For reasons of clarity and precision, a special terminology is used in this Study. This terminology is not always that used in the treaties on narcotic drugs. For example the concept of consumption used in this Study is much more inclusive than the definition in the Convention of 1961 (see paragraph 22 below). The term "production" is applied in the Convention of 1961 only to "the separation of opium, coca leaves, cannabis and cannabis resin from the plants from which they are obtained". We shall however speak of the production of poppy straw. The term "ton" or "tonne" refers to metric tons. 5. The term opiates is used in this Study to designate the phenanthrene alkaloids of opium and their derivatives which have been placed under international control. Diagram of opiate manufacture 6. Among the drugs used for medical and scientific requirements, the most important group from the point of view of the quantities consumed is made up of substances derived from various methods of processing the plant of the species Papaver somniferum. Nowadays, some of these substances are derived in very small part from the Papaver bracteatum plant. 1/ Diagram I gives a summary of the process whereby these substances are manufactured. 1/ See however paragraph 119 below. DIAGRAM I: OPIATES MANUFACTURE 7. The agricultural products of these two species of Papaver, used as raw materials in the manufacture of opiates, are opium and poppy straw on the one hand, and Papaver bracteatum straw on the other. 8. Morphine, natural codeine (as opposed to semi-synthetic codeine produced by methylation of morphine) and thebaine can be obtained from opium and poppy straw by straight extraction. The process of extracting these alkaloids from poppy straw is sometimes temporarily halted at the stage of concentrate of poppy straw, in which there is considerable trade. The principal extraction product of Papaver bracteatum straw is thebaine. Papaver bracteatum straw means all parts (except the seeds) of the plant of that species after harvesting. 9. Concentrate of poppy straw, thebaine and the bulk of morphine are used in the manufacture of other opiates of which the principal are semi-synthetic codeine, ethylmorphine, pholcodine, hydrocodone and oxycodone. In addition, dihydrocodeine is manufactured from codeine. Other products, such as heroin, hydromorphone, nicomorphine and acetyldihydrocodeine, are also manufactured by conversion. All these substances, including natural codeine and a very small proportion of the opium produced (2 %) and the morphine manufactured (1 %), are intended for use in preparations. Yields 10. It is useful to examine yields from the point of view both of control and of forecasts. In addition to the direct surveillance which can be exercised over harvest operations in the fields or over extraction and conversion in the factories, the calculation of the yield makes possible an indirect control of the security of the licit channels. Any reduction in yield not attributable to a specific cause should give rise to an investigation. Furthermore, the decision to cultivate an area of poppy adjusted to a final demand expressed in amounts by weight of different opiates will be well founded only if a whole series of yields are known at least approximately. 11. Opium is harvested in the form of latex, which may have a moisture content of up to 40%; it is then subjected to several conditioning processes for purposes of export, which reduce its moisture content to about 10% for Indian opium and 20% for Turkish opium. 2/ In the USSR opium was not intended for export and the latex was processed directly to extract the alkaloids. The moisture content may vary within certain limits over time. A small percentage variation in the moisture content results in a difference of several tonnes in the total harvest. This fact must be taken into consideration when the results for a year are drawn up and exports and imports are compared. 12. Poppy straw is subject to still greater variations especially if it is not compressed and processed into granules, as is done by certain manufacturers. Moreover, in the course of processing a not inconsiderable part (up to 8%) may be converted into a powder which is unusable for extraction because the morphine it contains is oxidized by contact with the air. 2/ Turkey decided not to produce opium after 1972.

Some preparations have been exempted by the 1961 Convention from certain measures of control because of the limited risks of abuse and drug recovery which they imply. These preparations, which are included in Schedule III of the 1961 Convention, are exempted in particular from the accounting system which enables national administrations to report to the INCB the precise use to which each narcotic drug has been put. Consequently, there are no statistics available on imports, exports, distribution or stocks of these preparations.
