Marijuana Laws by State: Where Marijuana Is Legal in 2026

Marijuana laws vary dramatically across the United States, with some states allowing licensed recreational sales and home cultivation while others continue to prohibit nearly all marijuana possession.

As of September 2026, 24 states have legalized marijuana possession for adults, while the District of Columbia also allows adult possession and home cultivation. Forty-one states have comprehensive medical marijuana laws, while several others allow only limited low-THC or CBD products.

Marijuana Legalization by State

For purposes of the table below, “legal” under adult use means state law allows adults 21 and older to possess at least some amount of marijuana for nonmedical purposes (aka recreational use). Under medical marijuana, “limited” means the state has a restricted CBD, low-THC or similarly narrow law rather than a comprehensive medical marijuana system, while “none” means the state does not have a state medical marijuana access program.

Marijuana Laws in Each State

Click any state name below for a detailed guide to that state’s marijuana laws, including possession limits, home cultivation, legal sales, and more.

Alabama

Adult-use marijuana remains illegal in Alabama. The state has legalized marijuana for certain medical purposes through a regulated medical program, but the law does not legalize recreational possession or personal cultivation. Certain hemp-derived THC products may be sold through separately licensed hemp retailers, subject to age, potency, testing and packaging requirements. Smokable hemp products are prohibited.

Alaska

Marijuana is legal for adults 21 and older in Alaska. Adults may possess up to one ounce and may cultivate up to six plants, with no more than three mature plants. State-licensed recreational marijuana stores are operational. Alaska does not allow intoxicating hemp products to be sold through its industrial hemp program. Consumer hemp products require state endorsement, which excludes products containing delta-9 THC or chemically modified cannabinoids.

Arizona

Adults 21 and older may possess up to one ounce of marijuana, including no more than five grams of concentrate. Adults may grow up to six plants at a private residence, with a maximum of 12 plants at a residence with multiple adults. Licensed recreational stores are operational. Arizona’s attorney general considers sales of intoxicating hemp-derived THC products, including delta-8 and THC-infused drinks and edibles, unlawful without a marijuana establishment license.

Arkansas

Recreational marijuana remains illegal in Arkansas. Voters approved medical marijuana in November 2016, and the first dispensary opened in May 2019. Registered patients with qualifying conditions may purchase marijuana from licensed dispensaries. Personal home cultivation remains prohibited. Arkansas prohibits intoxicating hemp products, including delta-8 and other restricted THC compounds, rather than allowing a separate recreational hemp market.

California

Adults 21 and older may legally possess up to 28.5 grams of marijuana and up to eight grams of concentrate. Adults may cultivate up to six plants at a private residence. California has a regulated recreational marijuana market with licensed cultivation, manufacturing, distribution and retail businesses. California prohibits detectable THC in hemp foods, beverages and dietary supplements, and bans hemp flower and hemp-derived THC inhalables. Legal intoxicating products must comply with the state’s licensed marijuana system.

Colorado

Colorado allows adults 21 and older to possess up to two ounces of marijuana. Adults may cultivate up to six plants, with no more than three mature at one time, subject to household and local restrictions. Licensed recreational marijuana sales have been legal since 2014. Low-THC hemp products can be sold outside marijuana stores only within state potency and cannabinoid-ratio limits. Chemically converted delta-8 and similar synthetic cannabinoids are prohibited.

Connecticut

Adults 21 and older may possess up to 1.5 ounces of marijuana in public and up to five ounces secured at a private residence. Adults may grow six plants, including no more than three mature plants, with a maximum of 12 plants per household. Licensed recreational stores are operational. High-THC hemp products are restricted to licensed marijuana sellers, while qualifying moderate-THC hemp products may be sold by separately registered vendors. THC-infused beverages have their own licensing and product rules.

Delaware

Adults 21 and older may possess up to one ounce of marijuana. Personal home cultivation remains prohibited. Recreational sales began through licensed businesses in 2025, including medical dispensaries that received approval to serve the adult-use market. Hemp and marijuana are regulated separately. A new framework taking effect October 21, 2026, authorizes qualifying hemp-derived THC beverages through licensed package stores and marijuana retailers, subject to potency, testing and labeling requirements.

Florida

Recreational marijuana remains illegal in Florida. Registered medical marijuana patients may purchase marijuana from licensed Medical Marijuana Treatment Centers under the state’s medical program. Florida allows qualifying hemp-derived THC products outside the medical marijuana program for adults 21 and older, subject to state testing, packaging, labeling and food-safety requirements.

Georgia

Adult-use marijuana remains illegal in Georgia, but the state’s medical program was significantly expanded in 2026. Beginning July 1, registered patients gained access to additional forms of medical marijuana, including raw plant material and vaporized products, while smoking or combustion remains prohibited. Registered patients may legally possess medical marijuana products containing up to a cumulative 12,000 milligrams of THC. Georgia allows certain consumable hemp products through licensed retailers for adults 21 and older, but prohibits retail sales of unprocessed hemp flower and leaves. THCA counts toward the state’s THC calculation.

Hawaii

Hawaii allows marijuana for medical purposes but has not legalized recreational use. The state has also decriminalized possession of small quantities of marijuana, meaning some low-level possession offenses are subject to reduced penalties rather than traditional criminal punishment. Hawaii allows certain low-THC manufactured hemp products under separate testing, labeling and product rules, but prohibits hemp flower, pre-rolls, vapes and cannabinoids made through chemical conversion.

Idaho

Idaho remains one of the country’s most restrictive states regarding marijuana. Recreational marijuana is illegal, and the state does not have a comprehensive medical marijuana program or a regulated marijuana dispensary system. Idaho requires finished consumer hemp products to contain no THC. The federal hemp threshold does not authorize the retail sale of THC-containing hemp products in the state.

Illinois

Marijuana is legal for adults 21 and older in Illinois. Beginning June 12, 2026, Illinois residents may possess up to 60 grams of marijuana flower, 10 grams of concentrate and products containing up to 1,000 milligrams of THC. Nonresidents are generally allowed half those amounts. Recreational home cultivation remains prohibited, although registered medical patients may grow up to five plants. Illinois restricts intoxicating hemp sales to adults 21 and older. Beginning November 12, 2026, products exceeding the new hemp limits are scheduled to fall under the state’s regulated marijuana system.

Indiana

Recreational and comprehensive medical marijuana remain illegal in Indiana. State law provides limited protections for certain low-THC or CBD products but does not establish a traditional medical marijuana program. Indiana prohibits smokable hemp, and the attorney general considers delta-8 and similar THC variants controlled substances. The state’s limited hemp exceptions should not be read as blanket authorization for intoxicating hemp products.

Iowa

Adult-use marijuana is illegal in Iowa. The state operates a limited medical cannabidiol program rather than the type of comprehensive medical marijuana system found in most states. Iowa allows registered consumable hemp products for adults 21 and older, with limits of four milligrams of total THC per serving and 10 milligrams per container. Inhalable hemp and synthetic cannabinoids are prohibited.

Kansas

Marijuana remains illegal for recreational purposes in Kansas, and the state does not have a comprehensive medical marijuana program. Kansas law provides a narrow legal defense involving certain low-THC CBD preparations. Kansas applies THC limits to hemp products, and its attorney general considers delta-8 controlled unless it falls within the narrow industrial-hemp exception. A product’s delta-9 percentage alone does not establish that it is lawful.

Kentucky

Recreational marijuana remains illegal in Kentucky. The state legalized medical marijuana in 2023, with the program taking effect in January 2025. Registered patients with qualifying conditions can now purchase medical marijuana from operational licensed dispensaries, although product availability varies by location. Personal home cultivation and smoking marijuana remain prohibited under the medical program. Kentucky separately regulates adult-use hemp-derived cannabinoid products, including qualifying THC products, for adults 21 and older. Sellers and products must meet state registration, testing, packaging and labeling requirements.

Louisiana

Louisiana has legalized marijuana for qualifying medical patients but not for recreational use. Marijuana is available to registered patients through the state’s regulated medical system, while certain low-level possession offenses have also been partially decriminalized. Louisiana allows approved consumable hemp products through authorized retailers under a separate regulatory system, with state product registration, THC limits and restrictions on product forms.

Maine

Adults 21 and older may possess up to 2.5 ounces of marijuana. Adults may also cultivate up to six mature plants, 12 immature plants and an unlimited number of seedlings for personal use. Licensed recreational marijuana stores are operational. Maine allows qualifying hemp-derived THC products outside its marijuana markets, subject to applicable food and business licensing rules. Products classified as potentially intoxicating hemp cannot be sold to anyone under 21.

Maryland

Adults 21 and older may possess up to 1.5 ounces of marijuana. Adults may grow up to two plants for personal use, and licensed recreational sales have been underway since July 2023. Maryland generally restricts intoxicating hemp products to its licensed marijuana system. Separate exceptions apply to qualifying low-THC products and certain hemp tinctures, while nonnaturally derived cannabinoids are prohibited.

Massachusetts

Adults 21 and older may possess up to two ounces of marijuana outside the home and up to 10 ounces at their primary residence. Adults may grow up to six plants for personal use, with a maximum of 12 plants at a residence. Licensed recreational retailers are operational. Massachusetts prohibits adding hemp-derived THC to food and beverages sold outside the licensed marijuana system. The federal hemp definition does not authorize ordinary retailers to sell THC-infused drinks or edibles.

Michigan

Adults 21 and older may possess up to 2.5 ounces of marijuana outside the home, including no more than 15 grams of concentrate. At home, adults may possess up to 10 ounces, plus marijuana harvested from plants lawfully cultivated on the premises. Recreational cultivation is limited to 12 plants per residence, regardless of how many adults live there. Licensed recreational stores are operational. Michigan regulates intoxicating THC products, including delta-8, through its licensed marijuana system. Hemp origin does not allow an unlicensed retailer to sell these products.

Minnesota

Adults 21 and older may possess up to two ounces of marijuana in public and up to two pounds at home. Adults may cultivate up to eight plants, no more than four of which may be mature at one time. Licensed recreational marijuana businesses are operational. Minnesota allows qualifying lower-potency hemp edibles and beverages through a separate licensing system overseen by its Office of Cannabis Management, with potency limits, testing requirements and sales restricted to adults 21 and older.

Mississippi

Recreational marijuana remains illegal in Mississippi. The state has a regulated medical marijuana program for registered patients, and possession of certain small amounts by nonpatients has been decriminalized. Mississippi’s attorney general considers consumable hemp products without FDA approval unlawful outside the regulated medical marijuana program, rather than recognizing a general retail market for hemp-derived THC.

Missouri

Adults 21 and older may possess up to three ounces of marijuana. Adults who obtain the required cultivation registration may grow up to six flowering plants, six immature plants and six smaller plants. Licensed recreational marijuana sales are operational. Missouri has enacted a transition bringing intoxicating hemp products under its licensed marijuana system beginning November 12, 2026, with ordinary retailers required to stop selling products covered by the new restrictions.

Montana

Adults 21 and older may possess up to one ounce of marijuana. Adults may generally grow up to two mature plants and two seedlings, with higher household limits where more than one adult resides. Licensed recreational marijuana stores are operational. Montana prohibits retail hemp products containing total THC unless authorized as a food or drug by the FDA. Synthetic cannabinoids are also prohibited in the state’s marijuana market.

Nebraska

Adult-use marijuana remains illegal, but medical marijuana is legal following voter approval of Initiative Measures 437 and 438 in 2024. Qualifying patients are protected for possession of up to five ounces for medical purposes. Nebraska has established a Medical Cannabis Commission and is continuing to implement its regulated medical marijuana system. Nebraska officials have pursued enforcement against synthetic THC products and products marketed as hemp that exceed legal THC limits. Their availability in stores does not establish that they are lawful.

Nevada

Adults 21 and older may possess up to 2.5 ounces of marijuana or up to one-quarter ounce of concentrate. Home cultivation of up to six plants is allowed for adults who do not live within 25 miles of a licensed marijuana retailer. Licensed recreational stores and marijuana consumption lounges operate in the state. Nevada counts THC isomers toward its hemp limits and treats products exceeding those limits as marijuana. Producing, distributing or selling synthetic cannabinoids requires approval from the Cannabis Compliance Board.

New Hampshire

Recreational marijuana remains illegal in New Hampshire. The state allows medical marijuana for qualifying patients and has decriminalized possession of small amounts for adults. New Hampshire does not authorize hemp-derived products containing more than 0.3% THC, including delta-8 or other THC isomers. A broader definition expressly including THCA takes effect January 1, 2027.

New Jersey

Adults 21 and older may legally possess up to six ounces of marijuana. Licensed recreational marijuana retailers are operational, but New Jersey remains one of the few adult-use states that prohibits personal home cultivation. New Jersey generally regulates intoxicating hemp products as marijuana, with a temporary exception for qualifying THC beverages sold through authorized businesses. That beverage exception ends in November 2026.

New Mexico

Adults 21 and older may possess up to two ounces of marijuana, 16 grams of extract and marijuana edibles containing up to 800 milligrams of THC. Adults may cultivate up to six mature plants for personal use. Licensed recreational sales are operational. New Mexico separately regulates hemp products, with strict total-THC limits and restrictions on synthetic and semisynthetic cannabinoids. Qualifying hemp products must meet state manufacturing, testing and labeling requirements.

New York

Adults 21 and older may possess up to three ounces of marijuana or 24 grams of concentrated marijuana. Adults may grow up to six plants, no more than three mature, with a maximum of 12 plants per household. Up to five pounds of marijuana may be kept at a private residence under state rules. New York allows qualifying low-THC products through its cannabinoid hemp program but prohibits chemically converted delta-8 and similar products. Intoxicating products do not qualify merely because their ingredients originated from hemp.

North Carolina

Adult-use marijuana remains illegal under North Carolina state law, and the state does not have a comprehensive medical marijuana program. A narrow CBD law applies to certain patients, and possession of small amounts has been partially decriminalized. Separate laws can apply on sovereign tribal lands within the state. North Carolina exempts qualifying hemp products containing no more than 0.3% delta-9 THC by dry weight from its controlled-substances law. That exemption is separate from marijuana legalization and does not override other applicable product laws.

North Dakota

North Dakota has a comprehensive medical marijuana program, but recreational marijuana remains illegal. The state has reduced penalties for certain low-level possession offenses. North Dakota prohibits hemp-derived THC products that produce intoxicating effects, including delta-8 and chemically converted cannabinoids. Qualifying nonintoxicating CBD and CBG products remain subject to separate hemp rules.

Ohio

Adults 21 and older may possess up to 2.5 ounces of marijuana flower and up to 15 grams of concentrate. Adults may cultivate six plants, with a maximum of 12 plants at a residence with multiple adults. Licensed recreational sales are operational. Ohio’s hemp definition excludes finished products containing more than 0.4 milligrams of combined total THC and specified similar-effect cannabinoids per container, as well as synthesized cannabinoids. THCA is included in the calculation.

Oklahoma

Oklahoma has one of the country’s largest medical marijuana programs, but adult-use marijuana remains illegal. Registered patients may purchase medical marijuana through state-licensed dispensaries and may cultivate marijuana under the medical program. Oklahoma officials have targeted unlawful sales of chemically altered hemp intoxicants such as delta-8. The state’s hemp law should not be interpreted as blanket authorization for psychoactive products sold outside medical dispensaries.

Oregon

Adults 21 and older may possess up to two ounces of marijuana in public and up to eight ounces at home. A household may grow up to four plants for personal use. Licensed recreational stores are operational. Oregon allows qualifying hemp-derived THC products outside marijuana stores under separate potency, testing, labeling and registration requirements. Products containing artificially derived cannabinoids face additional restrictions and generally cannot be sold through ordinary hemp retailers.

Pennsylvania

Recreational marijuana remains illegal in Pennsylvania. The state legalized medical marijuana in April 2016, and licensed dispensaries began serving patients in February 2018. Registered patients with qualifying conditions may purchase marijuana through the state’s medical program, but personal home cultivation remains prohibited. Several municipalities have separately adopted local marijuana decriminalization policies. Pennsylvania regulates hemp separately from medical marijuana, but the hemp program does not authorize every intoxicating product. State drug and food laws restrict some products marketed as delta-8, THC edibles or hemp beverages.

Rhode Island

Adults 21 and older may possess up to one ounce of marijuana in public and up to 10 ounces at home. Adults may cultivate six plants, no more than three of which may be mature. Licensed recreational sales are operational. Rhode Island allows qualifying low-THC hemp consumables through separately licensed sellers, with product-specific THC limits, testing and labeling requirements. This is distinct from its recreational marijuana retail system.

South Carolina

Recreational and comprehensive medical marijuana remain illegal in South Carolina. State law provides narrow access or protections involving certain CBD products with limited THC content. South Carolina treats qualifying hemp separately from marijuana, but officials have pursued criminal cases involving delta-8 and other THC products marketed as hemp. Retail availability does not establish that a product is lawful.

South Dakota

Adult-use marijuana remains illegal in South Dakota. Voters approved medical marijuana in 2020, and qualifying patients may participate in the state’s regulated medical marijuana program. South Dakota prohibits selling hemp products containing chemically derived cannabinoids, including converted delta-8 and delta-9 THC. Its hemp program does not establish a general recreational THC market.

Tennessee

Tennessee has not legalized recreational or comprehensive medical marijuana. State law provides limited exceptions involving certain low-THC cannabis oils and CBD products. Tennessee allows qualifying hemp-derived cannabinoid products through businesses licensed by its Alcoholic Beverage Commission. Total THC includes THCA, and products containing THCP or synthetic cannabinoids are prohibited.

Texas

Adult-use marijuana remains illegal in Texas. The state operates a medical marijuana program through the Texas Compassionate Use Program, which was substantially expanded by lawmakers in 2025. Texas allows qualifying hemp-derived delta-9 THC products through registered or licensed businesses, with sales restricted to adults 21 and older. Delta-8 above naturally occurring trace amounts is treated as a controlled substance.

Utah

Recreational marijuana remains illegal in Utah. Qualifying patients may obtain medical marijuana through the state’s regulated medical cannabis program and licensed pharmacies. Utah allows only qualifying, state-registered hemp cannabinoid products, subject to THC concentration, cannabinoid-ratio and serving limits. Hemp registration is separate from the medical marijuana program.

Vermont

Adults 21 and older may possess up to two ounces of marijuana. Personal cultivation is legal, with adults allowed up to six plants, no more than two of which may be mature at one time. Licensed recreational marijuana stores are operational. Vermont counts THCA when determining hemp’s THC content and regulates THC concentrates as marijuana regardless of their source. Hemp-derived intoxicants cannot bypass the state’s cannabis licensing requirements.

Virginia

Marijuana possession and home cultivation are legal for adults 21 and older in Virginia. Adults may possess up to two ounces in public and grow up to four plants per household. Adult-use retail sales are not yet operational, but Virginia enacted a regulated retail system in 2026 with sales scheduled to begin July 1, 2027. Since August 15, 2026, hemp products cannot exceed 0.3% total THC or two milligrams of total THC per package. The former exception for products with a high CBD-to-THC ratio no longer applies.

Washington

Adults 21 and older may possess up to one ounce of marijuana, seven grams of concentrate, 16 ounces of marijuana-infused solid products or 72 ounces of marijuana-infused liquid. Licensed recreational stores are operational. Washington does not allow adults to grow marijuana at home for recreational purposes, although qualified medical patients have separate cultivation rights. Washington prohibits unlicensed stores from selling products with detectable THC, including hemp-derived THC. Hemp origin does not exempt intoxicating products from the state’s marijuana retail restrictions.

West Virginia

Recreational marijuana remains illegal in West Virginia. Qualifying patients may obtain marijuana products through the state’s regulated medical marijuana program. West Virginia separately allows approved hemp-derived cannabinoid products for adults 21 and older. Products and sellers must register with the Department of Agriculture and comply with testing, labeling and other state requirements.

Wisconsin

Wisconsin has not legalized recreational marijuana or established a comprehensive medical marijuana program. State law provides a narrow exception involving certain nonintoxicating CBD products. Some municipalities have adopted their own reduced penalties for possession. Wisconsin distinguishes qualifying hemp from marijuana, allowing a separate hemp market subject to applicable product laws. Hemp vaping devices also face state certification requirements, and local restrictions may apply.

Wyoming

Recreational and comprehensive medical marijuana remain illegal in Wyoming. State law provides a limited exemption involving certain low-THC, high-CBD preparations for qualifying medical purposes. Wyoming prohibits synthetic substances in hemp products and counts psychoactive THC isomers toward its hemp limit. Products exceeding 0.3% THC after accounting for decarboxylation cannot be sold as legal hemp.

District of Columbia (Washington, D.C.)

Adults 21 and older in Washington, D.C., may possess up to two ounces of marijuana and cultivate up to six plants, with no more than three mature. A residence with multiple adults may contain no more than 12 plants, six of which may be mature. D.C. does not have a conventional licensed recreational marijuana retail market. D.C. does not recognize a separate retail exemption for hemp-derived THC under its cannabis laws. Businesses selling those products must operate within the District’s licensed medical marijuana system.

Is Marijuana Legal Under Federal Law?

Marijuana is not legal under federal law. However, in April 2026, the U.S. Department of Justice placed marijuana products regulated under qualifying state medical marijuana licenses, along with Food and Drug Administration-approved marijuana products, into Schedule III of the federal Controlled Substances Act. Marijuana outside those categories remains subject to Schedule I controls while the Drug Enforcement Administration (DEA) continues proceedings over broader marijuana rescheduling.

Frequently Asked Questions (FAQ) About Marijuana Laws by State

How many states have legalized recreational marijuana?

Twenty-four states have legalized marijuana possession for adults 21 and older. Washington, D.C., also allows adult possession, although it is not a state and does not have a conventional licensed recreational retail market.

How many states have legalized medical marijuana?

Forty-one states have comprehensive medical marijuana laws. Several additional states have more limited laws allowing certain low-THC or CBD products.

What is the difference between marijuana legalization and decriminalization?

Legalization makes specified marijuana activities lawful under state law when people follow requirements such as age and possession limits. Decriminalization reduces penalties for conduct that remains unlawful. Depending on the state, possession may result in a civil fine or a criminal offense with no jail time. Decriminalization alone does not authorize recreational retail sales or home cultivation.

Can you grow marijuana at home in every legal state?

No. Most adult-use states allow at least some personal cultivation, but several do not. Delaware, Illinois, New Jersey and Washington prohibit recreational home cultivation, although medical cultivation rights may differ. Nevada allows recreational home cultivation only under certain circumstances. For a detailed state-by-state comparison, see our Marijuana Home Grow Laws by State guide.

How much marijuana can you legally possess?

Marijuana possession limits vary considerably by state. Some states allow one ounce or less in public, while others allow two or three ounces, and separate limits may apply to concentrates, homegrown marijuana and medical patients. See our Marijuana Possession Limits by State guide for a state-by-state comparison.

Can you bring marijuana from one legal state to another?

State legalization does not authorize consumers to transport marijuana across state lines. Interstate transportation can implicate federal law even when marijuana is legal in both the state where the trip begins and the state where it ends.

Can tourists buy marijuana in states where recreational sales are legal?

Generally, yes. Adults 21 and older can typically purchase marijuana from licensed recreational retailers with valid government-issued identification, even if they live in another state. Some states impose lower purchase or possession limits on nonresidents. Purchases must remain within applicable state limits, and state legalization does not authorize taking marijuana across state lines.

Is a medical marijuana card valid in other states?

Not automatically. Some states recognize out-of-state medical marijuana cards, while others require visiting patients to obtain temporary registration or do not recognize outside cards. Rules may also distinguish between possessing medical marijuana and purchasing it from a dispensary. Patients should check the destination state’s requirements before traveling.

Is It Legal to Drive After Using Marijuana?

No state allows driving while impaired by marijuana, even when recreational or medical marijuana is legal. However, marijuana DUI standards vary by state. Some states use specific THC blood limits, while others rely on evidence of impairment or zero-tolerance rules. See our Marijuana DUI Laws by State guide for a complete state-by-state comparison.

Is marijuana legal on federal land in states where marijuana is legal?

No. State marijuana legalization does not itself authorize possession or use on federal property. The National Park Service, for example, prohibits marijuana possession and use within National Park Service areas even when the surrounding state has legalized marijuana. NPS is still explicitly stating this in current 2026 guidance.

Do all states with legal recreational marijuana have dispensaries?

No. Virginia allows adult possession and home cultivation but licensed recreational sales are not scheduled to begin until July 1, 2027. Washington, D.C., also permits adult possession without operating a conventional licensed recreational retail system.

Can local governments have stricter marijuana rules than their state?

In many states, yes. Cities and counties may have authority over issues including marijuana business locations, public consumption, zoning, operating hours and, in some cases, whether marijuana businesses may operate locally. Consumers should check both state and local rules.
