Cannabis legality by state in the U.S. breaks into four tiers: twenty-four states allow adult recreational use, another sixteen allow medical use only, several more permit limited CBD products or have decriminalized small amounts, and a shrinking group still treats any possession as a crime. Above all of them sits federal law, which continues to classify marijuana as a Schedule I controlled substance for most purposes, with one narrow exception created in April 2026.
What Federal Law Still Says
The Controlled Substances Act has placed cannabis in Schedule I since 1970, meaning the federal government treats it as highly addictive with no accepted medical use.1Office of the Law Revision Counsel. 21 U.S. Code 812 – Schedules of Controlled Substances Manufacturing, distributing, or possessing marijuana is a federal crime regardless of state law.2Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A
On April 28, 2026, the DEA published a final rule moving two narrow categories to Schedule III: FDA-approved drug products containing marijuana, and marijuana handled under a state-issued medical license.3Federal Register. Schedules of Controlled Substances: Rescheduling of Food and Drug Administration Approved Products Everything else, including all recreational cannabis, stays in Schedule I. A broader rescheduling hearing was set to begin on June 29, 2026.4United States Department of Justice. Justice Department Places FDA-Approved Marijuana Products and Products Containing Marijuana Subject to a Qualifying State-Issued License in Schedule III
Federal possession penalties remain on the books. A first-time simple possession conviction carries up to a year in prison and a minimum $1,000 fine.5Office of the Law Revision Counsel. 21 USC 844 – Penalties for Simple Possession Federal prosecutors rarely pursue small-quantity cases but have authority to do so, particularly on federal land such as national parks and military bases. Distribution penalties scale by quantity: 100 kilograms or 100-plus plants triggers a mandatory minimum of five years and up to forty, and 1,000 kilograms or 1,000-plus plants triggers ten years to life.2Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A These apply even in states where cannabis is fully legal.
States With Legal Recreational Use
Twenty-four states now allow adult-use cannabis. Colorado and Washington were first, legalizing through voter initiatives in November 2012. Colorado’s Amendment 64 allowed adults twenty-one and older to possess up to one ounce and built a licensed retail framework.6Colorado General Assembly. Amendment 64 Use and Regulation of Marijuana Washington’s Initiative 502 set the same age limit. Twenty-two states have joined them since.
The structure across these states is broadly similar. Adults twenty-one and older may buy from licensed retailers, possess up to one ounce of flower (with equivalent limits for concentrates and edibles), and in most cases grow a limited number of plants at home. Around sixteen of the recreational states allow home cultivation, typically capping individual grows at six plants. Household caps vary: some double the individual limit, others hold the same cap no matter how many adults live there.
Retail cannabis is taxed heavily. State excise rates run from roughly 6% to 37%, with local taxes often stacked on top. Revenues commonly fund education, infrastructure, and substance-abuse treatment. Commercial license fees for growers and sellers range from a few hundred dollars to over $60,000 per year depending on the state, license type, and locality.
Legalization has limits in every one of these states. Driving under the influence of cannabis remains a serious criminal offense with license suspension, fines, and possible jail time. Public consumption is prohibited almost everywhere, usually as a civil infraction. Every state restricts advertising, packaging, and marketing aimed at minors.
States With Medical-Only Programs
Forty states have medical cannabis laws of some kind, though sixteen of them stop short of recreational legalization. In a comprehensive medical state, a patient with a qualifying condition gets a physician recommendation, registers with the state, and buys from a licensed dispensary. Qualifying conditions typically include cancer, epilepsy, multiple sclerosis, chronic pain, PTSD, and glaucoma, with each state keeping its own list.
Patients receive a state-issued ID card. Annual fees run from nothing to roughly $100. The card shields the holder from state possession charges and grants dispensary access. Most programs also protect designated caregivers who buy and transport products for patients who can’t do so themselves.
Medical dispensaries often face tighter oversight than recreational stores. Products are routinely tested for pesticides, mold, and heavy metals. Some states require a pharmacist or trained consultant on site. Tax rates for medical products are usually lower than recreational rates, and some states exempt medical sales entirely.
A medical card doesn’t override federal law. It also doesn’t guarantee protection at work or at home, which matters for firearms, employment, and federally subsidized housing. More on those below.
Limited-Access and Decriminalized States
Several states that haven’t built comprehensive medical programs allow low-THC CBD products for a narrow set of severe conditions, typically intractable epilepsy. These laws commonly cap THC at 0.3% to 0.5% and limit participation to patients who have tried conventional treatments. Some of these states permit possession without providing any legal in-state source, which leaves patients in a gray zone.
Decriminalization is a separate approach. Instead of a legal market, it downgrades small-quantity possession from a jailable crime to a civil infraction. Virginia, for example, treats simple possession as a civil penalty of up to $100 for a first offense, $250 for a second, and $500 for a third.7Virginia State Legislative Information System. HB301 – Marijuana; Decriminalization of Simple Possession, Penalty Fines in decriminalized states generally fall between $100 and $600. The substance is confiscated, and repeat violations can bring escalating consequences including mandatory drug education.
Decriminalization is not legalization. There is no regulated retail market, no commercial licensing, and no legal way to buy the product. The goal is keeping people out of jail, not endorsing use.
Hemp Is Not Marijuana
The Agriculture Improvement Act of 2018 carved out a federal exception for hemp, defined as cannabis containing no more than 0.3% delta-9 THC on a dry weight basis.8Congressional Research Service. The 2018 Farm Bills Hemp Definition and Legal Implications Hemp-derived CBD can be grown, transported, and sold under federal law. Anything above 0.3% THC is marijuana and remains federally prohibited.
The Farm Bill prevents states from blocking the interstate transportation of legal hemp, but states can impose stricter production rules of their own. A CBD oil legal under federal law may still face state restrictions. The Act also doesn’t override FDA authority, so hemp-derived foods and supplements have their own regulatory layer. The 0.3% threshold is the bright line: a product that tests even slightly above it is legally marijuana, with all the federal consequences that follow.
U.S. Territories
The territories took divergent paths. Puerto Rico launched a medical program in 2015 through executive order. Guam legalized adult use in 2019, allowing possession of up to one ounce and home cultivation of up to six plants for adults twenty-one and older.9Justia Law. Guam Code Title 11, Division 1, Chapter 8 – Guam Cannabis Industry Act The U.S. Virgin Islands signed adult-use legislation in January 2023.10Pasquines. US Virgin Islands Governor Bryan Signs Adult-Use Cannabis Legislation Into Law The Northern Mariana Islands legalized in 2018 under the Taulamwaar Sensible CNMI Cannabis Act, allowing up to one ounce of possession and up to six immature plants.
American Samoa sits at the opposite end. A 1999 law imposes a mandatory five-year prison sentence with no possibility of parole for a first-time marijuana possession conviction, regardless of quantity.11National Drug Intelligence Center. American Samoa Drug Threat Assessment
One warning for travelers: federal law governs air travel and movement between territories and the mainland. Carrying cannabis across any jurisdictional boundary, even between two places where it is locally legal, is a federal offense.
Tribal Lands
Native American tribes are domestic dependent nations with sovereign authority to set their own drug policies on reservation land. A 2014 Justice Department memo signaled that federal marijuana enforcement on tribal lands would track the same priorities applied in states, which gave several tribes room to launch cannabis programs.12Department of Justice. Policy Statement Regarding Marijuana Issues in Indian Country Attorney General Jeff Sessions rescinded the underlying Cole Memorandum on January 4, 2018, returning enforcement discretion to individual U.S. Attorneys.13Congressional Research Service. Attorneys General Memorandum on Federal Marijuana Enforcement
Risk depends on geography. Tribes in legal states operate with less friction because state and local law enforcement are aligned with tribal policy. Tribes in prohibition states face greater exposure: state police may try to make arrests as products leave reservation boundaries, and federal prosecutors have more room to bring cases. Some tribes have reached cooperative agreements with surrounding states, but that option isn’t universally available.
What State Legalization Doesn’t Protect
Even in fully legal states, federal law still reaches into three areas that catch people off guard.
Firearms
Federal law prohibits any “unlawful user of or addicted to any controlled substance” from possessing, shipping, or receiving a firearm or ammunition.14Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Because marijuana is still federally controlled, any cannabis user, including a state-registered medical patient in a legal state, is a prohibited person for firearms purposes. ATF Form 4473, required for every firearm purchase from a licensed dealer, asks directly whether the buyer is an unlawful user of marijuana, and warns that federal law applies regardless of state legalization or decriminalization.15Bureau of Alcohol, Tobacco, Firearms and Explosives. Firearms Transaction Record Answering “no” while using cannabis is a federal felony; answering “yes” blocks the purchase. There is no state workaround.
Employment
Federal employees are covered by Executive Order 12564, which requires a drug-free workplace and authorizes testing. A positive cannabis test can bring discipline or termination regardless of where the employee lives. Workers in safety-sensitive transportation roles, including commercial truck drivers, airline pilots, and rail operators, face mandatory Department of Transportation drug testing, and cannabis remains on the panel with no state-law exception.16U.S. Department of Transportation. Procedures for Transportation Workplace Drug and Alcohol Testing Programs
For private-sector workers, the picture varies. The Americans with Disabilities Act doesn’t require employers to accommodate medical cannabis use because the drug remains federally illegal, and courts have broadly upheld firings based on positive marijuana tests even with a valid medical card. Roughly nine of the twenty-four recreational states and twenty-four of the forty medical states have enacted some form of employment protection for off-duty cannabis use, but the scope and strength of those protections vary.
Housing
Federally subsidized housing, including Section 8 voucher units and public housing, falls under HUD rules that require property owners to allow termination of tenancy for marijuana use because it is federally illegal. A tenant in a legal state who uses cannabis in their own apartment can be evicted from federally assisted housing. Private landlords in most states can prohibit cannabis through lease terms. A few legalization states have begun limiting landlords’ ability to penalize off-premises use, but these protections are far from universal.
The Bottom Line Across Jurisdictions
Where you are determines whether cannabis is a licensed retail product, a prescription-style medical treatment, a ticketed infraction, or a crime. What federal law says determines whether that state-level treatment protects you at work, at the gun counter, in your lease, or when you cross a state line. Both answers matter, and they rarely line up.
