Single Convention on Narcotic Drugs in the context of "International drug control conventions"

A controlled substance is generally a drug or chemical whose manufacture, possession, and use is regulated by a government, such as illicitly-obtained drugs or prescription medications that are designated by law. Some treaties, notably the Single Convention on Narcotic Drugs, the Convention on Psychotropic Substances, and the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, provide internationally agreed-upon "schedules" of controlled substances, which have been incorporated into national laws; however, national laws usually significantly expand on these international conventions.

Some precursor chemicals used for the illegal production of 'controlled drugs' are also controlled substances in many countries, even though they may lack the pharmacological effects of the drugs themselves. Substances are classified according to schedules and consist primarily of potentially psychoactive substances and anabolic steroids. The controlled substances do not include many prescription items such as antibiotics.

Chapter X of the United Nations Charter deals with the UN Economic and Social Council. Originally, Article 61 provided that ECOSOC would consist of 18 members, but in 1965 the Charter was amended to expand ECOSOC to 27 members, before being amended to include 54 in 1971. ECOSOC's members are elected by the UN General Assembly to staggered three-year terms, and are eligible for immediate re-election. This enables countries like the United States to be de facto permanent members. Article 62 empowers ECOSOC to "make or initiate studies and reports with respect to international economic, social, cultural, educational, health, and related matters" and to make recommendations "promoting respect for, and observance of, human rights and fundamental freedoms for all." It can prepare draft conventions and call international conferences – these have included, for instance, the 1961 New York conference that drafted the Single Convention on Narcotic Drugs. Article 64 gives ECOSOC concurrent power, along with the UN General Assembly, to receive reports from specialized agencies, provided that the subject matter falls within ECOSOC's purview. Article 68 empowers it to "set up commissions in economic and social fields and for the promotion of human rights."

The Controlled Drugs and Substances Act (French: Loi réglementant certaines drogues et autres substances) is Canada's federal drug control statute. Passed in 1996 under Prime Minister Jean Chrétien's government, it repeals the Narcotic Control Act and Parts III and IV of the Food and Drugs Act, and establishes eight Schedules of controlled substances and two Classes of precursors. It provides that "The Governor in Council may, by order, amend any of Schedules I to VIII by adding to them or deleting from them any item or portion of an item, where the Governor in Council deems the amendment to be necessary in the public interest."

The Act serves as the implementing legislation for the Single Convention on Narcotic Drugs, the Convention on Psychotropic Substances, and the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances.

The Convention on Psychotropic Substances of 1971 is a United Nations treaty designed to control psychoactive drugs such as amphetamine-type stimulants, barbiturates, benzodiazepines, and psychedelics signed in Vienna, Austria on 21 February 1971. The Single Convention on Narcotic Drugs of 1961 did not ban the many newly discovered psychotropics, since its scope was limited to drugs with cannabis, coca and opium-like effects.

During the 1960s, such drugs became widely available, and government authorities opposed this for numerous reasons, arguing that along with negative health effects, drug use led to lowered moral standards. The Convention, which contains import and export restrictions and other rules aimed at limiting drug use to scientific and medical purposes, came into force on 16 August 1976. As of 2013, 183 member states are Parties to the treaty. The treaty is not self-implementing; individual countries must pass domestic laws to enact punishments and restrictions. Though not all scheduled substances are restricted in all signatory countries, many laws have been passed to implement or exceed the requirements of the Convention, including the Canadian Controlled Drugs and Substances Act, the UK Misuse of Drugs Act 1971 and the U.S. Psychotropic Substances Act. Adolf Lande, under the direction of the United Nations Office of Legal Affairs, prepared the Commentary on the Convention on Psychotropic Substances. The Commentary, published in 1976, is an aid to interpreting the treaty and constitutes a key part of its legislative history.

The United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances of 1988 is one of three major drug control treaties currently in force. It provides additional legal mechanisms for enforcing the 1961 Single Convention on Narcotic Drugs and the 1971 Convention on Psychotropic Substances. The Convention entered into force on November 11, 1990. As of June 2020, there are 191 Parties to the convention. These include 186 out of 193 United Nations member states (not Equatorial Guinea, Kiribati, Papua New Guinea, Solomon Islands, Somalia, South Sudan, or Tuvalu) and the Holy See, the European Union, the Cook Islands, Niue, and the State of Palestine.

The legality of cannabis for medical and recreational use varies by country, in terms of its possession, distribution, and cultivation, and (in regards to medical) how it can be consumed and what medical conditions it can be used for. These policies in most countries are regulated by three United Nations treaties: the 1961 Single Convention on Narcotic Drugs, the 1971 Convention on Psychotropic Substances, and the 1988 Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. Cannabis is only scheduled under the Single Convention and was reclassified in 2020 to a Schedule I-only drug (from being both Schedule I and IV drug previously, with the schedules from strictest to least being IV, I, II, and III). As a Schedule I drug under the treaty, countries can allow the medical use of cannabis but it is considered to be an addictive drug with a serious risk of abuse. and may be able to regulate non-medical cannabis industry under its Article 2 paragraph 9.

The use of cannabis for recreational purposes is prohibited in most countries; however, many have adopted a policy of decriminalization to make simple possession a non-criminal offense (often similar to a minor traffic violation). Others have much more severe penalties such as some Middle Eastern and Far Eastern countries where possession of even small amounts is punished by imprisonment for several years. Countries that have legalized recreational use of cannabis are Canada, Germany, Luxembourg, Malta, South Africa, and Uruguay, plus 24 states, 3 territories, and the District of Columbia in the United States and the Australian Capital Territory in Australia. Commercial sale of recreational cannabis is legalized nationwide in two countries (Canada and Uruguay) and in all subnational U.S. jurisdictions that have legalized possession except Virginia and Washington, D.C. A policy of limited enforcement has also been adopted in many countries, in particular the Netherlands where the sale of cannabis is tolerated at licensed coffeeshops.

The Misuse of Drugs Act 1971 (c. 38) is an act of the Parliament of the United Kingdom. It represents action in line with treaty commitments under the Single Convention on Narcotic Drugs, the Convention on Psychotropic Substances, and the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances.

Offences under the act include:
