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. Since its descheduling in 2020, 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.
The gateway drug effect is a comprehensive catchphrase for the often observed effect that the use of a psychoactive substance is coupled to an increased probability of the use of further substances. Possible causes include biological alterations in the brain due to earlier substance exposure, as well as similar attitudes of people who use different substances, and therefore experience a "common liability to addiction". In 2020, the National Institute on Drug Abuse released a research report which supported allegations that marijuana is a "gateway" to more dangerous substance use; one of the peer-reviewed papers cited in the report claims that while "some studies have found that use of legal drugs or cannabis are not a requirement for the progression to other illicit drugs [...] most studies have supported the "gateway sequence"." However, a 2018 literature review conducted by the National Institute of Justice, which analyzed 23 peer-reviewed research studies, concluded "that existing statistical research and analysis relevant to the "gateway" hypothesis has produced mixed results", and that "no causal link between cannabis use and the use of other illicit drugs can be claimed at this time."
Cannabis, also known as marijuana or weed among other names, is a psychoactive drug from the cannabis plant. Native to Central or 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, such as cannabidiol (CBD). Cannabis can be used by smoking, vaporizing, within food, or as an extract.
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.
Drug liberalization is a drug policy process of decriminalizing or legalizing the use or sale of prohibited drugs. Variations of drug liberalization include: drug legalization, drug re-legalization and drug decriminalization. Proponents of drug liberalization may favor a regulatory regime for the production, marketing, and distribution of some or all currently illegal drugs in a manner analogous to that for alcohol, caffeine and tobacco.
The use, sale, and possession of cannabis containing over 0.3% THC by dry weight in the United States, despite laws in many states permitting it under various circumstances, is illegal under federal law. As a Schedule I drug under the federal Controlled Substances Act (CSA) of 1970, cannabis containing over 0.3% THC by dry weight is considered to have "no accepted medical use" and a high potential for abuse and physical or psychological dependence. Cannabis use is illegal for any reason, with the exception of FDA-approved research programs. However, individual states have enacted legislation permitting exemptions for various uses, including medical, industrial, and recreational use.
Cannabis is a plant used in Australia for recreational, medicinal and industrial purposes. In 2019, 36% of Australians over the age of fourteen years had used cannabis in their lifetime and 11.6% had used cannabis in the last 12 months.
In Colorado, cannabis has been legal for medical use since 2000 and for recreational use since late 2012. On November 7, 2000, 54% of Colorado voters approved Amendment 20, which amended the State Constitution to allow the use of marijuana in the state for approved patients with written medical consent. Under this law, patients may possess up to 2 ounces (57 g) of medical marijuana and may cultivate no more than six marijuana plants. Patients who were caught with more than this in their possession could argue "affirmative defense of medical necessity" but were not protected under state law with the rights of those who stayed within the guidelines set forth by the state. The Colorado Amendment 64, which was passed by voters on November 6, 2012, led to recreational legalization in December 2012 and state-licensed retail sales in January 2014. The policy has led to cannabis tourism. There are two sets of policies in Colorado relating to cannabis use: those for medicinal cannabis and for recreational drug use along with a third set of rules governing hemp.
Cannabis use disorder (CUD), also known as cannabis addiction or marijuana addiction, is a psychiatric disorder defined in the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and ICD-10 as the continued use of cannabis despite clinically significant impairment.
Cannabis is legal in Uruguay, and is one of the most widely used drugs in the nation.
Minors and the legality of cannabis is one of the issues around the legalisation of cannabis, with most jurisdictions placing strict age limits in a similar way as is done with the drinking age for alcohol.
Cannabis in Denmark is illegal for recreational use, but medical use is allowed through a four-year pilot program initiated in January 2018.
Cannabis in Latvia is illegal for recreational and medical purposes, but production of industrial hemp is permitted.
Cannabis is illegal in Turkey for recreational use, but allowed for limited medical and scientific purposes. The Turkish term for cannabis is kenevir.
Cannabis in Seychelles is illegal, with cultivation, possession and sale of the substance banned. Regardless of this, the controlled substance has seen continual use within Seychelles, with statistics indicating that more than a quarter of the nation's population are users of the drug, as well as use evident amongst adolescents. The drug is ingested in a variety of forms for medicinal or recreational use.
Cannabis has been legal in Nova Scotia and the entire country of Canada since October 17, 2018, the effective date of the Cannabis Act. Each province and territory set its own laws for various aspects, such as the legal age, whether householders can grow cannabis and the method of retail sales. Cannabis has been legal in Canada for medicinal purposes since 2001 under conditions outlined in the Marihuana for Medical Purposes Regulations, later superseded by the Access to Cannabis for Medical Purposes Regulations, issued by Health Canada and seed, grain, and fibre production was permitted under licence by Health Canada.
The following outline is provided as an overview of and topical guide to the plant Cannabis sativa and its relatives Cannabis indica and Cannabis ruderalis, the drug cannabis (drug) and the industrial product hemp.
