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 is classified as a Schedule I drug under the Single Convention treaty, meaning that signatories can allow medical use but that it is considered to be an addictive drug with a serious risk of abuse.
Medical cannabis, or medical marijuana (MMJ), is cannabis and cannabinoids that are prescribed by physicians for their patients. The use of cannabis as medicine has not been rigorously tested due to production and governmental restrictions, resulting in limited clinical research to define the safety and efficacy of using cannabis to treat diseases.

Cannabis, also known as marijuana among other names, is a psychoactive drug from the Cannabis plant. Native to Central and South Asia, the cannabis plant has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines for centuries. Tetrahydrocannabinol (THC) is the main psychoactive component of cannabis, which is one of the 483 known compounds in the plant, including at least 65 other cannabinoids, including cannabidiol (CBD). Cannabis can be used by smoking, vaporizing, within food, or as an extract.

Canada is the first G7 and G20 nation to do so.
In the United States, the non-medical use of cannabis is legalized in 19 states and decriminalized in 12 states as of May 2022. Decriminalization refers to a policy of reduced penalties for cannabis offenses, typically involving a civil penalty for possessing small amounts, instead of criminal prosecution or the threat of arrest. In jurisdictions without penalty the policy is referred to as legalization, although the term decriminalization is sometimes used for this purpose as well.
In the United States, the use and possession of cannabis is illegal under federal law for any purpose by way of the Controlled Substances Act of 1970 (CSA). Under the CSA, cannabis is classified as a Schedule I substance, determined to have a high potential for abuse and no accepted medical use – thereby prohibiting even medical use of the drug. Despite this, most states have legalized either or both the medical and recreational use of cannabis.
The legal history of cannabis in the United States began with state-level prohibition in the early 20th century, with the first major federal limitations occurring in 1937. Starting with Oregon in 1973, individual states began to liberalize cannabis laws through decriminalization. In 1996, California became the first state to legalize medical cannabis, sparking a trend that spread to a majority of states by 2016. In 2012, Washington and Colorado became the first states to legalize cannabis for recreational use.
Cannabis on American Indian reservations historically largely fell under the same regulations as cannabis nationwide in the United States. However, the August 2013 issuance of the Cole Memorandum opened discussion on tribal sovereignty as pertains to cannabis legalization, which was further explored as the states of Washington and Colorado legalized marijuana. A clarifying memo in December 2014 stated that the federal government's non-interference policies that applied to the 50 states, would also apply to the 326 recognized American Indian reservations. U.S. Attorney for Oregon, Amanda Marshall, stated that the clarification had been issued in response to legal questions from tribal nations, but that only three unnamed tribes, in California, Washington state, and "the Midwest" had stated explicit interest in legalizing.
Cannabis in Pennsylvania is illegal for recreational use, but possession of small amounts is decriminalized in several of the state's largest cities. Medical use was legalized in 2016 through a bill passed by the state legislature.

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.
The cannabis industry is composed of legal cultivators and producers, consumers, independent industrial standards bodies, ancillary products and services, regulators and researchers concerning cannabis and its industrial derivative, hemp.

Tell Your Children: The Truth About Marijuana, Mental Illness and Violence is a 2019 book by Alex Berenson. In it, Berenson makes harsh claims that cannabis use directly causes psychosis and violence, claims denounced as alarmist and inaccurate by many in the scientific and medical communities. The scientists state that Berenson is drawing inappropriate conclusions from the research he cites, primarily by inferring causation from correlation, as well as cherry picking data that fits his narrative, and falling victim to selection bias via his use of anecdotes to back up his assertions.
A cannabis cookbook is a cookbook for preparing cannabis edibles, often in the form of a baking guide. According to The New York Times, baking recipes are popular because "[THC] dosing is easier to control in batter-based dishes or chocolate". Such cookbooks existed prior to United States legalization; The Alice B. Toklas Cook Book published in 1954, for instance, or The Marijuana Chef Cookbook published in 2001 under the pseudonym S.T. Oner, but became more commonplace after California and other states legalized in the 2010s. Notable chefs like Laurie Wolf and Jasmine Shimoda have created or contributed to cannabis cookbooks.
The Marijuana Justice Act (S.597) was a 2019 bill to remove cannabis from the Controlled Substances Act, sponsored by U.S. Senator Cory Booker. An identical bill, H.R.1456, was introduced in the House of Representatives. The bill was co-sponsored by a number of contenders for the Democratic Party's nomination for U.S. President in the 2020 election, including Kamala Harris, Elizabeth Warren, Kirsten Gillibrand, Michael Bennet, and Bernie Sanders. In February 2019, it was referred to the Committee on the Judiciary. An identically titled bill had been introduced by Senator Booker in the 2017–2018 Congress and was called "among the most notable efforts" around legalization in that session. Besides removing cannabis from the Controlled Substances Act, the bill also sought to set up a community reinvestment fund, provide for expungement of past drug convictions, and penalize states that enforce cannabis laws disproportionately.
