1961 international treaty regulating narcotic drugs
The Single Convention on Narcotic Drugs, 1961 (Single Convention, 1961 Convention, or C61) is an international treaty that controls activities (cultivation, production, supply, trade, transport) involving specific narcotic drugs and lays down a system of regulations (licenses, measures for treatment, research, etc.) for their medical and scientific uses, concluded under the auspices of the United Nations. The Convention also establishes the International Narcotics Control Board.
The Single Convention was adopted in 1961 and amended in 1972. As of 2022, the Single Convention as amended has been ratified by 186 countries. The convention has since been supplemented by the 1971 Convention on Psychotropic Substances, which controls LSD, MDMA, and other psychoactive pharmaceuticals, and the 1988 United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances; the three conventions establish the legal framework for international drug control and the war on drugs.
Ratification.
The Single Convention as amended in 1972 had been ratified or acceded to by 186 states. Only Chad remained party to the original 1961 Convention in its unamended form. The Cook Islands, Equatorial Guinea, Kiribati, Nauru, Niue, Samoa, South Sudan, Timor-Leste, Tuvalu, and Vanuatu are not parties.
Since the Single Convention is not self-executing, parties must enact legislation to carry out its provisions, and the UNODC works with countries' legislatures to ensure compliance.
History.
The League of Nations adopted several drug control treaties prior to World War II, such as the International Opium Convention, and "International Convention relating to Dangerous Drugs (1925)" specifying uniform controls on addictive drugs such as cocaine and opium, and its derivatives. However, the lists of controlled substances were fixed in the treaties' text. Consequently, it was necessary to periodically amend or supersede the conventions with the introduction of new treaties to keep up with advances in chemistry. According to a 1954 interview with United States Commissioner of Narcotics Harry J. Anslinger, the cumbersome process of conference and state-by-state ratification could take many decades.
A Senate of Canada committee reported: "The work of consolidating the existing international drug control treaties into one instrument began in 1948, but it was 1961 before an acceptable third draft was ready." That year, the UN Economic and Social Council convened a plenipotentiary conference of 73 nations for the adoption of a single convention on narcotic drugs. That meeting was known as the United Nations Conference on Narcotic Drugs. The participating states organized themselves into five distinct caucuses:
These competing interests, after more than eight weeks of negotiations, finally produced a compromise treaty. Several controls were weakened; for instance, the proposed mandatory embargoes on nations failing to comply with the treaty became recommendations. The 1953 New York Opium Protocol, which had not yet entered into force, limited opium production to seven countries; the Single Convention lifted that restriction, but instituted other regulations and put the International Narcotics Control Board in charge of monitoring their enforcement. A compromise was also struck that allowed heroin and some other drugs classified as particularly dangerous to escape absolute prohibition.
The Single Convention created four Schedules of controlled substances and a process for adding new substances to the Schedules without amending the treaty. The Schedules were designed to have significantly stricter regulations than the two drug "Groups" established by predecessor treaties. For the first time, cannabis was added to the list of internationally controlled drugs. In fact, regulations on the cannabis plant – as well as the opium poppy, the coca bush, poppy straw and cannabis tops – were embedded in the text of the treaty, making it impossible to deregulate them through the normal Scheduling process. A 1962 issue of the Commission on Narcotic Drugs' "Bulletin on Narcotics" proudly announced that "after a definite transitional period, all non-medical use of narcotic drugs, such as opium smoking, opium eating, consumption of cannabis (hashish, marijuana) and chewing of coca leaves, will be outlawed everywhere. This is a goal which workers in international narcotics control all over the world have striven to achieve for half a century."
A 3 August 1962, Economic and Social Council resolution ordered the publication of the Commentary on the Single Convention on Narcotic Drugs. The legal commentary was written by the United Nations Secretary-General staff member Adolf Lande, the former Secretary of the Permanent Central Narcotics Board and Drug Supervisory Body, operating under a mandate to give "an interpretation of the provisions of the Convention in the light of the relevant conference proceedings and other material." The Commentary contains the Single Convention's legislative history and is an invaluable aid to interpreting the treaty.
The Single Convention entered into force on 13 December 1964, having met 's requirement of 40 ratifications. As of 1 January 2005, 180 states were Parties to the treaty. Others, such as Cambodia, have committed to becoming Parties.
On 21 May 1971, the UN Economic and Social Council called a conference of plenipotentiaries to consider amendments to the Single Convention. The conference met at the United Nations Office at Geneva from 6 to 24 March 1972, producing the 1972 Protocol Amending the Single Convention on Narcotic Drugs. The amendments entered into force on 8 August 1975.
On 11 November 1990, mechanisms for enforcing the Single Convention were expanded significantly by the entry into force of the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, which had been signed at Vienna on 20 December 1988. The to this treaty acknowledges the inadequacy of the Single Convention's controls to stop "steadily increasing inroads into various social groups made by illicit traffic in narcotic drugs and psychotropic substances". The new treaty focuses on stopping organized crime by providing for international cooperation in apprehending and convicting gangsters and starving them of funds through forfeiture, asset freezing, and other methods. It also establishes a system for placing precursors to Scheduled drugs under international control. Some non-Parties to the Single Convention, such as Andorra, belong to this treaty and thus are still under the international drug control regime.
Provisions.
Purposes.
Medical and scientific purposes.
The Single Convention repeatedly affirms the importance of medical use of controlled substances. The notes that "the medical use of narcotic drugs continues to be indispensable for the relief of pain and suffering and that adequate provision must be made to ensure the availability of narcotic drugs for such purposes". Articles 1, 2, 4, 9, 12, 19, and 49 contain provisions relating to "medical and scientific" use of controlled substances. In almost all cases, parties are permitted to allow dispensation and use of controlled substances under a prescription, subject to record-keeping requirements and other restrictions.
The Single Convention unambiguously condemns "abuse of drugs", even stating that "addiction to narcotic drugs constitutes a serious evil for the individual and is fraught with social and economic danger to mankind". It takes a prohibitionist approach to the problem of drug addiction, attempting to stop all uses considered "abuse" or "addiction." requires nations to limit use and possession of drugs to medicinal and scientific purposes. allows countries to phase out coca leaf chewing, opium smoking, and other traditional drug uses gradually, but provides that "the use of cannabis for other than medical and scientific purposes must be discontinued as soon as possible".
The discontinuation of these prohibited uses is intended to be achieved by cutting off supply. Rather than calling on nations to prosecute drug users, the treaty focuses on traffickers and producers. As of 2013, 234 substances are controlled under the Single Convention.
Non-medical and non-scientific purposes.
In the Single Convention, "other than medical and scientific purposes" are not subject to the general legal framework established in Article 4 (c), being exempt by a series of provisions referred to in article 4 (c). Some analysts suggest the "recreational use" of drugs is part of the "other than medical and scientific purposes," and therefore exempt from the measure of control of the convention, which are limited to "medical and scientific purposes;" others analysts have, however, suggested that "other than medical and scientific purposes" does not encompass recreational use.
Malta seem to have followed article 2 paragraph 9 of the Single Convention, which allow for the use of drugs, other than medical and scientific, in the context of industry.
Penal provisions.
As scholars note: "although formally binding, the penal provisions prove remarkably soft" and, as explained in the Commentary on the Single Convention, they are "rather vague, and [admit] escape clauses for the benefit of those Governments to which even such vague norms would be unacceptable."
 requires Parties to adopt measures against "cultivation, production, manufacture, extraction, preparation, possession, offering, offering for sale, distribution, purchase, sale, delivery on any terms whatsoever, brokerage, dispatch, dispatch in transit, transport, importation and exportation of drugs contrary to the provisions of this Convention," as well as "[i]ntentional participation in, conspiracy to commit and attempts to commit, any of such offences, and preparatory acts and financial operations in connexion with the offences referred to in this article", but it does not directly require criminalization of all the above; it states only in the cases of (unspecified) serious offences that they "shall be liable to adequate punishment particularly by imprisonment or other penalties of deprivation of liberty."
The Article also provides for extradition of drug offenders, although a Party has a right to refuse to extradite a suspect if "competent authorities consider that the offense is not sufficiently serious." A 1972 amendment to the Article grants nations the discretion to substitute "treatment, education, after-care, rehabilitation and social reintegration" for criminal penalties if the offender is a drug abuser. A loophole in the Single Convention is that it requires Parties to place anti-drug laws on the books, but does not clearly mandate their enforcement.
Drug enforcement varies widely between nations. Many European countries, including the United Kingdom, Germany, and, most famously, the Netherlands, do not prosecute all petty drug offenses. Dutch coffee shops are allowed to sell small amounts of cannabis to consumers. However, the Ministry of Health, Welfare and Sport's report, "Drugs Policy in the Netherlands", notes that large-scale "[p]roduction and trafficking are dealt with severely under the criminal law, in accordance with the UN Single Convention. Each year the Public Prosecutions Department deals with an average of 10,000 cases involving infringements of the Opium Act." Some of the most severe penalties for drug trafficking are handed down in certain Asian countries, such as Malaysia, which mandate capital punishment for offenses involving amounts over a certain threshold. Singapore mandates the death penalty for trafficking in 15 g (half an ounce) of heroin, 30 g of cocaine or 500 g of cannabis. Most nations, such as France and the United States, find a middle ground, imposing a spectrum of sanctions ranging from probation to life imprisonment for drug offenses.
The Single Convention's penal provisions frequently begin with clauses such as "Subject to its constitutional limitations, each Party shall..." Thus, if a nation's constitution prohibited instituting the criminal penalties called for by the Single Convention, those provisions would not be binding on that country.
Possession for personal use.
It is unclear whether or not the treaty requires criminalization of drug possession for personal use. The treaty's language is ambiguous, and a ruling by the International Court of Justice would probably be required to settle the matter decisively. However, several commissions have attempted to tackle the question. With the exception of the Le Dain Commission, most have found that states are allowed to legalize possession for personal use.
The Canadian Le Dain Commission of Inquiry into the Non-Medical Use of Drugs' 1972 report cites circumstantial evidence suggesting that states must prohibit possession for personal use:
 ;templatestyles src="Template:Blockquote/styles.css" / ;It has generally been assumed that "possession" in includes possession for use as well as possession for the purpose of trafficking. This is a reasonable inference from the terms of , which obliges the parties "to limit exclusively to medical and scientific purposes the production, manufacture, export, import, distribution of, trade in, use and possession of drugs". There is also , which provides that "The Parties shall not permit the possession of drugs except under legal authority." ... On the face of it would not be unreasonable to argue that what is contemplated is possession for the purpose of trafficking rather than possession for use, and that the requirements of the article are satisfied if the former kind of possession is made a penal offense. The prevailing view, however, is that the word "possession" in includes simple possession for use.
However, LeDain himself concludes
