The Controlled Substances Act (CSA) is the statute establishing federal U.S. drug policy under which the manufacture, importation, possession, use, and distribution of certain substances is regulated. It was passed by the 91st United States Congress as Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970 and signed into law by President Richard Nixon. The Act also served as the national implementing legislation for the Single Convention on Narcotic Drugs.
The prohibition of drugs through sumptuary legislation or religious law is a common means of attempting to prevent the recreational use of certain intoxicating substances.
The legality of cannabis for medical and recreational use varies by country, in terms of its possession, distribution, and cultivation, and 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 was reclassified in 2020 to a Schedule I-only drug under the Single Convention treaty, 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.
The Misuse of Drugs Act 1971 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.

In the United States, increased restrictions and labeling of cannabis as a poison began in many states from 1906 onward, and outright prohibitions began in the 1920s. By the mid-1930s cannabis was regulated as a drug in every state, including 35 states that adopted the Uniform State Narcotic Drug Act. The first national regulation was the Marihuana Tax Act of 1937.

The Cannabis Act (C-45) of June, 2018 paved the way for the legalization of cannabis in Canada on 17 October 2018. Police and prosecution services in all Canadian jurisdictions are currently capable of pursuing criminal charges for cannabis marketing without a licence issued by Health Canada. The Supreme Court of Canada has held that the federal Parliament has the power to criminalize the possession of cannabis and that doing so does not infringe upon the Canadian Charter of Rights and Freedoms. The Ontario Court of Appeal and the Superior Court of Ontario have, however, held that the absence of a statutory provision for medical marijuana is unconstitutional, and to that extent the federal law is of no force and/or effect if a prescription is obtained. The recreational use of cannabis has been legalized by the federal government, and took effect on 17 October 2018.
