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.

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.

Legalization Timeline

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.

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.
