Twenty-two states – along with Washington, D.C. and Guam – have acted to legalize recreational Cannabis

On Election Day in 2012, voters in Colorado and Washington approved ballot measures to legalize the recreational use and sale of cannabis, making the states the first in the U.S. to do so.

Twenty-one other states, Washington, D.C., and Guam would act to legalize the drug in the next 10 years as public support for legalization rose rapidly – despite marijuana being illegal at the federal level.

Some strains of the cannabis plant – often called marijuana or weed – contain a psychoactive compound called THC that produces a “high” when ingested.

Today, support for marijuana legalization has become mainstream among Democratic politicians, and some Republicans also back the idea. State legislatures are grappling with if and how to legalize the drug, while several marijuana-related bills – including those aiming to decriminalize it on the federal level – have been introduced in Congress. The House passed a marijuana decriminalization bill on April 1, 2022 and months later, several senators – including Senate Majority Leader Chuck Schumer – introduced the Cannabis Administration and Opportunity Act, which would federally decriminalize weed, as reported by Marijuana Moment. The bill’s future in the Senate is uncertain.

The movement toward relaxing punishment on marijuana use took a new turn on Oct. 7, 2022, when President Joe Biden said he will issue pardons to everyone convicted of the federal crime of simple marijuana possession, while calling for governors to make similar moves for convictions under state laws. The proclamation will apply to about 6,500 Americans, but a senior White House official clarified to reporters that no one is currently behind bars for simple possession of marijuana.

Opponents say marijuana poses a public health and safety risk, and some are morally against legalization. Proponents, however, argue that it is not as dangerous as alcohol and point to evidence that it has therapeutic benefits, such as stress and pain relief.

Advocates also see it as a moneymaker for states and a necessary social justice initiative. Marijuana laws have disproportionately affected people from minority communities, contributing to mass incarceration. States where the drug is legal have sought to retroactively address the consequences of marijuana prohibition, often including provisions allowing for the expungement or vacation of low-level marijuana convictions.

A December 2022 study published by the American Medical Association found that complete legalization reduces marijuana-related arrests even in states that had already decriminalized cannabis, meaning the drug is still illegal but a person would not be prosecuted for possession under a specified amount.

States where legal recreational marijuana has been approved:

Retail marijuana hit the shelves in Vermont in October 2022 and in New York in December of that year. The District of Columbia, on the other hand, still doesn’t have a regulated recreational market despite marijuana use being legal there. Meanwhile, Guam officials in November 2021 got closer to launching the territory’s own industry by contracting with Metrc, a provider of cannabis regulatory systems. It was later announced that the government would start accepting licensing applications at the end of August 2022 from “responsible officials” to participate in the island’s recreational cannabis industry, according to the Pacific Daily News.

Elsewhere, lawmakers in several states, including Minnesota and Ohio, are expected to consider passing marijuana legalization bills in 2023. In another – Oklahoma – a ballot measure that would have legalized recreational use failed to get enough votes on March 7.

READ: Recreational Marijuana: A Business Boon for States?

States have their own processes for licensing dispensaries, but in all states where marijuana is legal, businesses that sell marijuana must have a license from the state to do so.

The sales are regulated and taxed by the states at varying rates. Some states implement an excise tax on the sales, which are taxes on a particular good – in this case, marijuana – levied on the seller, which typically passes it on to the consumer by including it in the product’s price.

Provisions outlining the amount of marijuana an adult can legally possess, if adults can grow their own marijuana plants and how the tax revenue is spent vary from state to state.

Colorado – legalization measure approved November 2012

Adults over the age of 21 in Coloradocan possess and give away up to an ounce of marijuana and grow up to six plants each, though residences are limited to 12 plants total no matter how many people live there. Using marijuana in public is illegal.

Retail purchases at licensed dispensaries are subject to standard sales tax, plus an additional 10% marijuana sales tax. A 15% excise tax is applied to the wholesale price of retail marijuana – that is, the price that businesses pay cultivators.

Washington – legalization measure approved November 2012

In Washington, adults over 21 can buy and possess up to an ounce of marijuana,16 ounces of marijuana-infused edibles in solid form, 72 ounces of marijuana-infused liquid products,and 7 grams of marijuana concentrates. It’s illegal to consume marijuana in public, and recreational users can’t grow the plants at home.

Retail sales are legal at licensed dispensaries and there is a 37% excise tax on those sales.

Alaska – legalization measure approved November 2014

Alaskan adults over the age of 21 can possess and give away up to an ounce of marijuana and can grow up to six marijuana plants, though only three of those plants can be mature. It’s illegal to consume the drug in public.

Oregon – legalization measure approved November 2014

Adults in Oregon who are over 21 years old can possess up to an ounce of marijuana if they are in public and up to 8 ounces at home. Adults can also have up to 16 ounces of a marijuana product if it is in solid form, like an edible, or up to 72 ounces of a marijuana product in liquid form.

It is legal for adults over 21 to possess up to 2 ounces of marijuana and to give up to 1 ounce of marijuana to another person. Adults can also grow up to six marijuana plants, three of which can be mature.

Recreational cannabis sales are not legal in D.C., as Congressional Republicans have consistently included language in appropriations bills that prevents the District from establishing an independent regulatory board. Without licensed retailers, D.C.’s adult-use marijuana trade relies on gifting services.

California – legalization measure approved November 2016

It is legal in California for an adult over 21 to possess, purchase or give away up to an ounce of cannabis and as much as 8 grams of concentrated cannabis. Adults can also cultivate up to six live cannabis plants. Smoking or ingesting marijuana is illegal in public places, as is using the drug while in a car.

Michigan – legalization measure approved November 2018

It is legal for adults over 21 in Michigan to grow, consume and possess marijuana. The law allows individuals to grow up to 12 plants in a household, and to possess up to 2.5 ounces of the drug and 15 grams of concentrated marijuana.

The state’s Marijuana Regulatory Agency began accepting applications for retail licenses in late 2019. Michigan now operates licensed retailers for recreational cannabis use, as well as provisioning centers for medical use, according to David Harns, interim communications director for Michigan’s Department of Licensing and Regulatory Affairs.

Vermont – legalization measure approved January 2018

It was legal to grow and possess marijuana in Vermont, but not to buy or sell it at first – that changed in October 2022, when retailers started receiving licenses. Adults over 21 can have up to an ounce of marijuana and can grow two mature and four immature marijuana plants per household.

Guam – legalization measure approved April 2019

Adults over the age of 21 can possess up to an ounce of marijuana and can grow up to six plants, though no more than three can be mature.

Guam’s Cannabis Control Board scrambled to establish trading guidelines earlier in 2020, but its progress was stopped at the time by the coronavirus pandemic. The island has made more progress in establishing its recreational market since then.

Illinois – legalization measure approved May 2019

As of January 2020, it’s legal for Illinois residents over 21 to possess 30 grams of marijuana, 5 grams of concentrated cannabis and products containing up to 500 milligrams of THC. Adults who are not Illinois residents can have half those amounts while in the state. Consumption remains illegal in public places.

Residents could initially purchase marijuana for adult use from licensed dispensaries, followed by a gradual rollout of recreational retail licenses. Sales are taxed based on how much THC the marijuana contains: Cannabis with more than 35% THC will be taxed at 25% while cannabis with less THC will be taxed at 10%. Though marijuana has become more potent over the years, it’s still unusual for a strain to exceed 35% THC. Cannabis-infused products will be subject to a 20% tax. Local municipalities can also levy up to a 3% tax on sales.

New Jersey – legalization measure approved November 2020

New Jersey was among four new states to simultaneously back marijuana legalization measures on Election Day 2020. Nearly 67% of voters approved a ballot initiative to legalize marijuana. The measure outlines that only adults over the age of 21 would be able to use cannabis. It authorized the existing state commission on medical cannabis to govern the market for recreational use, and made the cannabis trade subject to state and local taxes. On Feb. 22, 2021, Gov. Phil Murphy signed legislation formally establishing the state’s recreational marketplace, while reducing penalties for underage possession of marijuana and alcohol.

Montana – legalization measure approved November 2020

Montana’s Election Day 2020 ballot featured two popular-vote measures that would regulate the use of recreational marijuana. Initiative 190 – legalizing the possession and use of limited amounts of cannabis by adults 21 and over – was approved by nearly 57% of voters, according to the Montana secretary of state. Montana Constitutional Initiative 118 – which allows the state legislature to set an age for marijuana use and consumption – passed with 58% of the vote.

South Dakota – legalization measure approved November 2020, struck down by state Supreme Court November 2021

South Dakota’s Constitutional Amendment A appeared on the 2020 ballot, passing with roughly 54% of the vote. The measure allows adults over 21 years old to possess and distribute up to 1 ounce of cannabis. A simultaneous measure to legalize medical marijuana was approved by nearly 70% of voters, according to the Sioux Falls-based Argus Leader. But in late November 2021, the state Supreme Court nullified the voter-passed amendment that would have allowed for recreational marijuana use, as reported by The Associated Press. The decision followed a lawsuit backed by Republican Gov. Kristi Noem. A similar measure failed to get enough votes in the state in November 2022.

Arizona – legalization measure approved November 2020

Arizona’s Proposition 207 would allow limited marijuana use, possession and cultivation by adults over age 21; ban smoking it in public; establish state and local regulation of marijuana licensees; and allow marijuana offenses to be expunged. About 60% of voters supported the measure on Election Day.

New York – legalization measure approved March 2021

Gov. Andrew Cuomo signed the Marihuana Regulation and Taxation Act on March 31, 2021. The law allows individuals age 21 or older to possess up to 3 ounces of cannabis for recreational purposes, establishes two regulatory agencies to oversee its sale and distribution, and clears the way for individuals convicted of marijuana-related offenses to have their records expunged. Democrats in the State Assembly had been introducing legalization bills since 2013, but their efforts were unsuccessful due to disagreements with Cuomo, according to the New York Times. The state finally started its sales of legal, adult-use regulated cannabis in late December 2022.

Virginia – legalization measure approved April 2021

On April 7, 2021, both chambers of Virginia’s General Assembly passed SB1406, with amendments put forth by Gov. Ralph Northam. Since the legislature approved the governor’s amendments, no further action was needed to pass the law, a staff member for Northam confirmed. The amended legislation allows Virginians age 21 or older to possess up to 1 ounce of recreational marijuana as of July 1, 2021. While the law also allows residents to grow up to four cannabis plants, the measure as enacted doesn’t establish a framework for licensing retail sales of adult-use marijuana. As of January 2023, the recreational market for marijuana in Virginia had an uncertain future, with a bill establishing a framework for retail sales still under consideration by the state’s politically divided government, as reported by WRIC-TV.

New Mexico – legalization measure approved April 2021

New Mexico Gov. Michelle Lujan Grisham signed HB2 on April 12, allowing adults over age 21 to grow cannabis plants at home and possess up to two ounces outside their homes as of June 29, according to Linda Trujillo, the state’s regulation and licensing superintendent. State-licensed dispensaries started selling recreational marijuana on April 1, 2022. Home growers of cannabis are able to cultivate up to six plants per person, or 12 total per household.

Connecticut – legalization measure approved June 2021

Connecticut legalized recreational cannabis on June 22, 2021, when Gov. Ned Lamont signed SB1201. When the measure took effect on July 1, individuals aged 21 or older were then able to possess up to 1.5 ounces of recreational cannabis, in addition to another five ounces in a home or vehicle. Prior low-level marijuana offenses were also expunged under the new law. Retail sales eventually began in January 2023.

Rhode Island – legalization measure approved May 2022

Rhode Island Gov. Dan McKee signed into law on May 25, 2022, a state legislature bill that legalizes, regulates and taxes cannabis in the state. The law legalizes possession of up to an ounce of cannabis and cultivation of up to three cannabis plants in a private residence for adults 21 and older, according to the Marijuana Policy Project. Sales – overseen by a new regulatory commission – officially began in December 2022.

Maryland – legalization measure approved November 2022

Voters’ Election Day ballot approval of Question 4 paved the way for Maryland adults to possess and use cannabis as early as July 2023. Companion legislation passed in the Maryland General Assembly stipulates that citizens would be allowed to possess up to 1.5 ounces, repeals the term “marijuana” and replaces it with cannabis, and offers a pathway toward expungement and resentencing for people convicted of certain cannabis offenses. State lawmakers unveiled a bill in early February that details how Maryland would tax and regulate cannabis, according to Marijuana Moment.

Missouri – legalization measure approved November 2022

Voters in Missouri also approved recreational marijuana legalization on Election Day 2022 through a ballot measure, which will limit possession to up to 3 ounces. The result cleared the path for legalized cannabis use in a state that was among the 10 with the most marijuana possession arrests reported by state and local agencies between 2017 and 2021, according to a U.S. News analysis of data available through the FBI. A registration card will be required for “personal cultivation,” there will be a 6% tax on the retail price of cannabis and citizens with certain non-violent marijuana-related offenses can petition to have their records expunged. Retail sales later began on Feb. 3 after the state health department began approving dispensary permits earlier than anticipated, according to the AP.

Delaware – legalization measure approved April 2023

In a unique situation within the realm of marijuana legalization in states, a recreational cannabis bill became law in Delaware on April 23, 2023 without the signature of Gov. John Carney, a Democrat. The governor, who had previously vetoed a legalization bill, allowed the measure through but clarified in a statement that his views “have not changed,” according to the AP. While the governor previously expressed concerns about marijuana’s effects on young people and highway safety, he said he decided not to veto the bill because Delaware officials have “spent far too much time focused on this issue, when Delawareans face more serious and pressing concerns every day.” The legalization bill allows state residents aged 21 and older to possess up to 1 ounce of marijuana but prohibits them from growing their own for personal consumption. A separate bill – which was set to become law on April 27, the AP reported – creates the recreational industry for Delaware by calling on state officials to issue up to 30 initial retail cannabis licenses, 30 manufacturing licenses and other related licenses.

Is marijuana legal at the federal level?

No. Marijuana is classified at the federal level as a Schedule I drug under the Controlled Substances Act, meaning that the government believes it to have no medical use and a high potential for abuse. Cultivating, distributing and possessing marijuana violates federal drug laws. But President Biden’s proclamation on Oct. 7, 2022, included a request for the secretary of health and human services and the attorney general “to initiate the administrative process to review expeditiously how marijuana is scheduled under federal law.”

States that have legalized either recreational or medical marijuana have done so in direct conflict with the federal government, creating tension between the rights of states to create their own laws and the authority of the federal government.

The federal government has, however, generally taken a hands-off approach to marijuana prohibition enforcement in states where the drug is legal. In 2009, the Obama administration told federal prosecutors to consider not prosecuting people who distributed marijuana in accordance with state medical marijuana laws.

What is the Cole Memorandum?

In 2013, the Justice Department issued perhaps the most influential memo on federal marijuana enforcement. Known as the Cole Memorandum, the Justice Department said it would not challenge states’ legalization laws at that time and expected states to have robust enforcement efforts of their own.

Then-Attorney General Jeff Sessions rescinded the Cole Memo in 2018, and told prosecutors to use established prosecutorial principles and their own judgment when prosecuting – or declining to pursue – marijuana charges.

The Justice Department has in general declined to pursue cases where individuals are acting in compliance with state law, and it has also not challenged state legalization laws in court. Observers notethat even after Cole’s withdrawal, most marijuana-related prosecutions by the Department of Justice have focused on more serious charges such as firearms or organized crime.

What does decriminalization mean?

Decriminalization is, broadly defined, the reduction of penalties for a certain criminal act or the process of reclassifying a criminal offense as a civil offense.

As of April 2023, the Marijuana Policy Project reports that 31 states and the District of Columbia have decriminalized low-level marijuana possession offenses, typically removing the possibility of jail time at least for first time-offenses, though the possibility of a fine or a criminal record remains in some places. Some states have reclassified the possession of small amounts of weed as a civil, instead of criminal, offense, while others have just reduced the penalties. In most of those states, repeat offenses, sales, distribution or possession of large amounts of marijuana can still land you in jail.

Of the states that have passed decriminalization measures, some have medical marijuana laws. Two states have decriminalized marijuana but not legalized it in any form, according to thePolicy Project.

Decriminalization is often seen as a middle ground between full-blown legalization and strict, punitive drug policy that has disproportionately affected communities of color.

Where does the public stand on the issue?

A growing majority of Americans believe that recreational marijuana should be legal. A CBS News/YouGov poll released in April 2022 found that two-thirds of Americans want recreational marijuana use to be legalized under federal law and in their own state. A previous Pew Research Center survey found similar levels of support for marijuana legalization.

Americans have warmed significantly to the idea in recent years. Just 12% of U.S. adults supported legalization in 1969, according to a November 2021 Gallup poll – a figure that rose to 31% in 2000 before accelerating above 50% after 2013 and to a record high of 68% most recently.

Democrats are more likely to support legalization, though a majority of Republicans are now in favor of it, Gallup found. People under age 30 are similarly more likely to back marijuana legalization – 81% of those respondents in 2019 – but 62% of Americans aged 50 to 64 also supported legalization, a previous version of the Gallup survey found.
