|More than half of US adults, over 128 million people, have tried marijuana, despite it being an illegal drug under federal law. Nearly 600,000 Americans are arrested for marijuana possession annually – more than one person per minute. Public support for legalizing marijuana went from 12% in 1969 to 66% today. Starting with Colorado and Washington in 2012, recreational marijuana, also known as adult-use marijuana, has been legalized by ten states and DC.
Proponents of legalizing recreational marijuana say it will add billions to the economy, create hundreds of thousands of jobs, free up scarce police resources, and stop the huge racial disparities in marijuana enforcement. They contend that regulating marijuana will lower street crime, disrupt the drug cartels, and make marijuana use safer through required testing, labeling, and child-proof packaging. They say marijuana is a relatively harmless herb, and that adults should have a right to use it if they wish.

Opponents of legalizing recreational marijuana say it will increase teen use and lead to more medical emergencies including traffic deaths from driving while high. They contend that revenue from legalization falls far short of the costs in increased hospital visits, addiction treatment, environmental damage, crime, workplace accidents, and lost productivity. They say that marijuana use harms the user physically and mentally, and that its use should be strongly discouraged, not legalized.
Pot. Weed. Ganja. Mary Jane. There are more than a thousand slang terms in the English language to refer to marijuana. A 1943 article in TIME magazine called it muggles, mooter, and bambalacha, and referred to marijuana cigarettes as goof-butts and giggle-smokes. According to the Oxford English Dictionary, use of the word "marijuana" (also written as "marihuana" in older references) came to popularity in the United States in the 1930s as an alternative to the more familiar terms "cannabis" and "hemp."
Cannabis, the scientific name for marijuana, is a plant that has three species (or strains): cannabis indica, cannabis sativa, and the less common cannabis ruderalis. Marijuana and hemp are both cannabis plants, but marijuana contains higher levels of THC (delta-9-tetrahydrocannabinol), the primary psychoactive ingredient that causes people to get high. Hemp can be cultivated for industrial uses such as rope and burlap fabric, or for a low-THC, non-psychoactive, medicinal product. This website uses the words "cannabis" and "marijuana" interchangeably, and the words "recreational" and "adult-use" interchangeably.
Marijuana legalization refers to the practice of allowing and regulating the production, distribution, sale, and possession of cannabis so that marijuana use within the established rules is no longer a crime. There are different models of legalization, ranging from allowing people to grow their own marijuana to nonprofit co-ops to for-profit commercialization with retail sales.
Early History of Cannabis in the United States
While references to marijuana as a popular medicine are found in Chinese writings dating back to 2900 BC, the marijuana plant made its arrival in North America in 1611 thanks to the Jamestown settlers. Early colonists were required to grow hemp. George Washington and Thomas Jefferson grew hemp for clothing, rope, and fishing nets in the 1770s. By the 1800s, doctors were using cannabis extracts for various ailments, and marijuana was listed in the United States Pharmacopeia as a treatment for opiate addiction, leprosy, cholera, and more. In the mid-1800s, hemp was the third-largest crop in the United States, behind cotton and tobacco.

Trend towards Outlawing Marijuana, Early 1900s
At the start of the 20th century, drugs were largely unregulated: beverages such as Coca-Cola contained cocaine, heroin was sold as an over-the-counter medicine, and cannabis was available in tinctures. The 1906 Pure Food and Drug Act, which specifically mentioned cannabis indica, kicked off drug regulation in the United States by requiring ingredient labeling in drugs and food. The 1914 Harrison Narcotics Act, which regulated and taxed opiates and cocaine, was soon followed by the 1918 prohibition of alcohol.
Mexican immigrants entered the United States in record numbers following the 1910 Mexican Revolution. They reportedly introduced Americans to smoking marijuana for recreational purposes. Around the same time, sailors and West Indian immigrants brought marijuana from the Caribbean into North America via New Orleans. In the 1920s and 1930s, recreational cannabis use became associated with the jazz music, and the famous trumpet player Louis Armstrong was an early advocate for marijuana.
The rise of the word "marijuana" (from the Spanish "marihuana") as a replacement for the then-familiar terms cannabis and hemp is often attributed to prohibitionists, like Harry Anslinger, the first commissioner of the Federal Bureau of Narcotics, who wanted to associate cannabis with demeaning or racist stereotypes about Mexican immigrants and other minorities. Following the 1933 repeal of alcohol prohibition, Anslinger focused on fighting marijuana, which had already been banned in 29 states by 1931. He tried to turn public opinion against cannabis with quotes such as: "There are 100,000 total marijuana smokers in the U.S., and most are Negroes, Hispanics, Filipinos and entertainers. Their Satanic music, jazz and swing result from marijuana use. This marijuana causes white women to seek sexual relations with Negroes, entertainers and any others." His efforts were aided by a 1936 anti-marijuana propaganda film, Reefer Madness, as well as by newspaper publisher William Randolph Hearst, who famously printed articles designed to foster fear of the drug.

1937, the Year Marijuana Became Illegal
The 1937 Marihuana Tax Act effectively outlawed cannabis use in the United States by adding strict regulations and prohibitive taxes that made marijuana too expensive to buy or sell legally. It became a federal crime to possess marijuana, including hemp, without having the required tax stamps. Importers and manufacturers of marijuana were required to pay an annual tax of $24 (more than $400 in 2018 dollars). Transfers of marijuana to non-registered people were subject to a tax of up to $100 per ounce (more than $1,700 in 2018 dollars). Legal transfers of marijuana involved special order forms and strict record keeping. Violations of the Act were subject to fines of up to $2,000 ($34,260 in 2018 dollars) and five years in prison. In October 1937, Samuel Caldwell became the first marijuana seller convicted under US federal law and he was sentenced to four years of hard labor at Leavenworth Penitentiary.

Marijuana from 1938 through the Sixties
In 1938, New York City Mayor Fiorella LaGuardia directed the New York Academy of Medicine to research marijuana. Their report became one of the first comprehensive reviews of the drug's impact. The 1944 LaGuardia report concluded that "The practice of smoking marihuana does not lead to addiction… Marihuana is not the determining factor in the commission of major crimes... The publicity concerning the catastrophic effects of marihuana smoking in New York City is unfounded." The findings infuriated Commissioner Anslinger, who denounced the report as a "government-printed invitation to youth and adults - above all teenagers - to go ahead and smoke all the reefers they feel like." The report did not alter federal marijuana policy.
Marijuana remained popular with musicians, artists, writers, and others throughout the 1940s and 1950s. Marijuana use became more common on college campuses in the 1960s alongside the rise of the hippie counterculture and Vietnam war protests. It also became more widespread among upper-middle class white Americans. Efforts to re-legalize marijuana grew stronger. The 1965 arrest of Timothy Leary, a Harvard psychologist who experimented with hallucinogens and became a counterculture icon, led to the Marihuana Tax Act being overruled by the Supreme Court in 1969. The court agreed with Leary's argument that the law violated his fifth amendment right against self-incrimination because he wouldn't have been able to follow the law’s registration requirements without admitting to breaking state marijuana bans.
President Nixon and the 1970 Controlled Substances Act
In 1970, President Nixon signed the bill that makes marijuana illegal under federal law to this day. As a party to the 1961 Single Convention Treaty, the United States was required to limit marijuana use "exclusively to medical and scientific purposes." That obligation was implemented with the 1970 Controlled Substance Act (CSA). Under the CSA, drugs were put into one of five categories based on their medical use and potential for abuse. Marijuana was placed in the most restrictive category, Schedule I, which was designated for "drugs with no currently accepted medical use and a high potential for abuse," along with heroin and LSD. Drugs such as cocaine and methamphetamine were placed in the less restrictive Schedule II.
Marijuana's placement in Schedule I was supposed to be temporary pending a federal review by the newly formed National Commission on Marihuana and Drug Policy (more commonly known as the Shafer Commission). The commission's 1972 report concluded that "neither the marihuana user nor the drug itself can be said to constitute a danger to public safety," and recommended that marijuana possession for personal use no longer be considered a criminal offense. President Nixon's response was, "[R]eading it did not change my mind. I oppose the legalization of marijuana." Regardless of the commission's recommendation, marijuana was left in Schedule I and remains there today.
NORML, Holland, and Decriminalization
The same year that the CSA was enacted, 1970, the National Organization for the Reform of Marijuana Laws (NORML) was founded to advocate for the end of marijuana prohibition. Between 1973 and 1981, the organization successfully fought to get minor marijuana offenses decriminalized in 11 states and lower penalties for marijuana possession in other states.
A policy of decriminalization was adopted in the Netherlands in 1976 for what it deemed "soft drugs," which included cannabis. Under the Dutch Opium Act, possession of less than five grams of marijuana is presumed to be for personal use and is therefore not prosecuted. The law also allows for coffee shops where people are able to buy and use cannabis. Decriminalization of marijuana means people don't get arrested for possessing small amounts of marijuana, and may be required to pay a civil fine instead of facing criminal charges. This is a step towards loosening marijuana prohibition, but is not considered to be legalization. Today, some marijuana legalization opponents advocate for decriminalization instead.
Marijuana at the End of the 20th Century
In the 1980s, a rise in parent groups concerned about the increase in teen drug use coincided with the election of President Ronald Reagan, who in 1982 declared a "war on drugs," echoing the phrase popularized by Nixon. First Lady Nancy Reagan spearheaded the "Just Say No" campaign aimed at convincing kids not to use drugs and seeking to overturn lenient drug laws. Parent lobbying groups such as the National Federation of Parents for Drug-Free Youth, now known as National Family Partnership, established a presence in Washington, DC, to advocate for anti-drug legislation. Throughout the 1980s, federal and state criminal penalties for marijuana became stricter and mandatory-minimum sentences were established.

Marijuana arrests increased dramatically in the 1990s, more than doubling between 1990 and 2002, from 327,000 to 697,000 annually. In New York City, marijuana arrests jumped 882% in that period. A report from the Sentencing Project stated, "Our analysis indicates that the 'war on drugs' in the 1990s was, essentially, a 'war on marijuana.'" At the same time, public opinion was shifting in favor of medical marijuana. In 1996, California became the first state to legalize marijuana for medical purposes when voters passed Proposition 215. By the end of 2000, eight states had legalized medical marijuana. By 2017, 29 states and Washington, DC, had legalized it.
Trend towards Recreational Marijuana Legalization
Although a 2010 California proposition to legalize adult-use marijuana failed, measures to legalize recreational marijuana were on the ballots in three states two years later, in Nov. 2012. While Oregon voters turned down the measure, Colorado and Washington became the first two US states to legalize adult-use marijuana. Support for legalizing recreational marijuana increased as more people, including many who never tried marijuana, believed that marijuana use was not as dangerous as the government reported and not a gateway to using hard drugs. People were also becoming unhappy with the sheer cost of enforcing marijuana laws and the growing prison populations, especially among minority populations. Plus, more people were exposed to marijuana and "out-in-the-open" marijuana users thanks to liberalized marijuana policies in medical marijuana states. Younger generations were increasingly more likely to support legalization. Marijuana, however, remained an illegal Schedule I drug under federal law.
Concerns about how the federal government would react to the new laws were lessened somewhat with a 2013 communication from President Obama's Justice Department known as the Cole memo. Deputy Attorney General James M. Cole stated that so long as states had good regulations, then the federal government would hold off on challenging marijuana legalization. Marijuana retail stores opened in Colorado on Jan. 1, 2014, allowing adults 21 and older to purchase cannabis that is taxed and regulated under state law. Washington's marijuana shops opened on July 8, 2014.

In Nov. 2014, Oregon and Alaska passed recreational marijuana ballot measures following the same model as Washington and Colorado, which is a for-profit commercial marijuana industry that allows retail sales. That same year, Washington, DC, voters approved an initiative that allowed home cultivation and personal possession but not retail sales. In the Nov. 2016 election, California, Maine, Massachusetts, and Nevada all passed legal recreational ballot measures that follow the commercialization model, although retail sales in Maine were put on hold by the state legislature. In Jan. 2018, Vermont became the first state to legalize marijuana by way of the state legislature rather than by ballot initiative, enacting a law that did not allow for retail sales.
The election of President Trump in 2016 and his appointment of Jeff Sessions as US Attorney General in 2017 raised new questions about whether the federal government would crack down on states that were legalizing adult-use marijuana. On Jan. 4, 2018, Sessions issued a memo that undid the hands-off policy enacted by President Obama's Justice Department, and instructed federal prosecutors to determine for themselves when to prosecute marijuana activities.
On June 7, 2018, Senator Elizabeth Warren (D-MA) and Senator Cory Gardner (R-CO) introduced the Strengthening the Tenth Amendment Through Entrusting States (STATES) Act, which they say "ensures that each State has the right to determine for itself the best approach to marijuana within its borders." Asked about the legislation, President Trump said, "I support Senator Gardner. I know exactly what he's doing. We're looking at it. But I probably will end up supporting that, yes."
On Oct. 17, 2018, Canada's Cannabis Act took effect, allowing adults age 18 and over to possess, share, purchase, and grow marijuana. Canada was the second country to legalize marijuana, following Uruguay's 2013 legalization.
President Trump signed the Agriculture Improvement Act of 2018 (known as the Farm Bill) into law on Dec. 20, 2018. This law legalized industrial hemp that contains less than 0.3% THC by removing it from the Controlled Substances Act. Cannabidiol (CBD) and tetrahydrocannabinol (THC) remain federally illegal to include in food or health products without FDA approval, even if they were derived from hemp.
