Where is cannabis legal in short?
Cannabis is legal for adults 21 and older in 24 US states plus Washington DC and a handful of US territories, and legal for medical use in 38 states. It remains illegal under federal US law, where marijuana is a Schedule I controlled substance. Hemp-derived CBD with less than 0.3% delta-9 THC is federally legal in every state.
where can i buy cannabis legally
Is cannabis legal at the federal level in the United States?
No. Federal law still lists marijuana as a Schedule I drug under the Controlled Substances Act, alongside heroin and LSD. That classification means federal agents, federal land, and federal benefits programs follow stricter rules than state law.
Airports, national parks, military bases, and interstate transport fall under federal jurisdiction. Even in a legal state, carrying cannabis onto federal property can create legal exposure.
where is cannabis legal for recreational use
Which states allow recreational cannabis?
As of early 2025, 24 states allowed adult-use cannabis, with retail sales operating or phasing in across most of them. Ages and possession limits vary by state.
- Alaska, Arizona, California, Colorado, Nevada, Oregon, Washington
- Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Michigan
- Minnesota, Missouri, Montana, New Jersey, New Mexico, New York, Ohio
- Rhode Island, Vermont, Virginia
Virginia legalized possession for adults but had not launched statewide retail sales. Delaware and Minnesota were still building out licensed store networks.
Which states allow medical cannabis only?
Roughly 38 states have a medical cannabis program, and many of them limit access to cardholders with qualifying conditions. Examples include Alabama, Arkansas, Florida, Hawaii, Iowa, Kentucky, Louisiana, Mississippi, North Dakota, Oklahoma, Pennsylvania, South Dakota, Texas, Utah, and West Virginia.
Rules differ widely. Some programs allow flower, others permit only oils, tinctures, or low-THC extracts. A physician certification is normally required.
Which states still ban cannabis entirely?
As of early 2025, Idaho, Kansas, and Wyoming had not implemented a medical cannabis program. A few other states allowed only very low-THC CBD products rather than full medical marijuana.
Is CBD legal where cannabis is not?
Yes, in most cases. The 2018 Farm Bill removed hemp and hemp-derived CBD from the Controlled Substances Act when delta-9 THC stays at or below 0.3% on a dry weight basis.
State rules still matter. Some states restrict CBD in food, impose age minimums, or require lab testing and labeling. Buying from a brand that publishes third-party lab results is the simplest way to confirm a product is compliant.
Where is cannabis legal outside the United States?
Canada, Uruguay, Malta, and Luxembourg allow adult-use cannabis nationally, and Germany permits limited adult possession and cultivation. South Africa allows private adult use after a 2024 court change.
Thailand tightened its rules in 2025 and returned to medical-only access after several years of broad legal sales. Mexico allows personal possession under court rulings but has no working retail system.
What is the difference between cannabis, marijuana, and hemp?
Cannabis is the plant genus. Marijuana refers to cannabis with high THC, while hemp refers to cannabis with 0.3% THC or less. That single number is what separates a federally legal CBD product from a federally illegal drug.
Can cities ban cannabis even in a legal state?
Yes. Many legal states let counties and cities opt out of retail sales, so a legal state can still have dry towns. Local zoning, license caps, and distance rules often decide whether a dispensary ever opens.
How do I check the rules where I live?
Start with your state cannabis regulatory agency or health department website, then check your city ordinances. Confirm the legal age, possession limit, where use is allowed, and whether home cultivation is permitted before you buy anything.
Rules change often through ballot measures and legislation, so verify current status rather than relying on older summaries.
