Where Is Cannabis Legal for Medical Use?
Medical cannabis is legal in about 39 US states and the District of Columbia as of 2025. Idaho, Kansas, and Wyoming have no medical cannabis law, and a few other states allow only low-THC CBD oils. Cannabis stays illegal under federal law for any use outside FDA-approved medicines and licensed research.
Each state runs its own program, so qualifying conditions, purchase limits, taxes, and product types differ from one state to the next.
If you are asking where cannabis is legal for medical use, start with your state health agency. The sections below cover state programs, card steps, federal rules, and countries outside the US.

Which US States Have Medical Cannabis Programs?
Most medical states allow flower, edibles, oils, tinctures, and topicals. Patients register with the state or hold a physician's recommendation, then buy from licensed dispensaries.
- Broad programs (flower and high-THC products): Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Hawaii, Illinois, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Dakota, Utah, Vermont, Virginia, Washington, West Virginia, and the District of Columbia.
- Limited programs (CBD or low-THC oil only): Georgia, Indiana, Iowa, North Carolina, South Carolina, Tennessee, Texas, and Wisconsin.
- New or in rollout: Alabama and Nebraska passed medical laws, but dispensaries are not open in every part of either state.
Idaho, Kansas, and Wyoming have no patient registry and no legal medical product. Possession of THC in those states can lead to criminal charges.
What Conditions Qualify for Medical Cannabis?
States write their own list of qualifying conditions. A diagnosis that qualifies in one state may be rejected in another.
- Chronic pain and severe muscle spasms
- Cancer and chemotherapy side effects such as nausea and vomiting
- Epilepsy and seizure disorders
- Post-traumatic stress disorder
- Multiple sclerosis and Crohn's disease
- Glaucoma
- HIV/AIDS and wasting syndrome
- Terminal illness
- Anxiety, autism, or opioid use disorder (only in some states)
Several states add a catch-all clause. A physician can certify a patient when cannabis may help and other treatments have failed.
How Do You Get a Medical Cannabis Card?
The process looks similar in most states, though fees and paperwork differ.
- Check your state program for qualifying conditions and residency rules.
- Book a visit with a physician certified in your state. Many states allow telehealth.
- Submit the certification or application to the state health agency.
- Pay the registration fee. Costs run from $25 to $200 in most states, and some states waive fees for veterans or low-income patients.
- Buy from a licensed dispensary once the card arrives. Most cards last one year, so plan the renewal.
Is Medical Cannabis Legal Under Federal Law?
No. Cannabis is a Schedule I controlled substance under the federal Controlled Substances Act, and that status has not changed. Federal law does not recognize state medical cards.
Congress has blocked the Justice Department from spending funds to prosecute patients and providers who follow state medical cannabis law. That protection comes through an annual appropriations rider, so it must be renewed each budget cycle.
The FDA has approved a few cannabis-related prescription drugs, including a CBD oral solution for severe childhood epilepsy and synthetic THC medicines for nausea and weight loss. A proposal to move cannabis to Schedule III has been under review since 2024, and the outcome is not settled.
Federal rules still matter for patients. Crossing state lines with cannabis, flying with it, using it on federal land, or buying a firearm can create legal risk even in a state where cannabis is legal.
Where Is Medical Cannabis Legal Outside the United States?
More than 50 countries allow some form of medical cannabis or cannabis-based medicine. Access ranges from full pharmacy sales to narrow prescription programs.
- Canada: patients need a doctor's authorization and buy from licensed producers.
- Germany: doctors can prescribe medical cannabis, and a 2024 law eased access.
- Australia: prescription only, filled through a pharmacy.
- United Kingdom: specialist doctors can prescribe, but public health service prescriptions stay rare.
- Israel: a long-running medical program with patient licenses.
- Netherlands, Italy, Poland, Czech Republic, Portugal: pharmacy-based medical cannabis with a prescription.
- Brazil, Mexico, Colombia, Chile, Uruguay, Jamaica: medical or CBD access under national rules.
- Thailand, South Africa, New Zealand: medical cannabis by prescription.
A US state card carries no weight abroad, and importing cannabis is a crime in most countries. Check local rules before you travel.
Frequently Asked Questions
Is medical cannabis legal in all 50 US states?
No. About 39 states and DC have a medical cannabis program. Idaho, Kansas, and Wyoming have no medical cannabis law, and several states limit patients to CBD or low-THC oil.
Can I use my medical card in another state?
Some states accept out-of-state cards and many do not. In states with recreational sales, adults 21 and older can buy without a card. Rules change, so confirm with the state program before you travel.
Do I need a medical card in a state with recreational cannabis?
Not for a legal purchase if you are 21 or older. A card still helps: patients often pay less tax, buy more at one visit, and get access to higher-dose products.
What is the difference between medical and recreational cannabis?
Both come from the same plant. The difference sits in the rules. Medical patients register with a state, work with a physician, and hold protections that vary by jurisdiction. Recreational buyers need only proof of age.
Does a medical card protect me at work?
Not always. Employers in many states can test for cannabis and enforce drug-free workplace policies. A few states bar employers from firing patients who use cannabis off the clock, so read your state law.
What to Know Before Buying Medical Cannabis
Buy from a state-licensed dispensary. Unlicensed sellers face no testing rules, and products can carry mold, pesticides, or labels that list the wrong potency.
- Ask for a certificate of analysis (COA) that covers THC and CBD content plus contaminant testing.
- Check the label for serving size and total THC per package.
- Bring your card and a photo ID when you shop.
- Store products away from children and pets.
State programs change each legislative session. Confirm current rules with your state health department before you apply or renew.
