38 states and the District of Columbia have legalized comprehensive medical cannabis programs, and 24 of those states also allow adult-use sales. Six more states permit only limited low-THC or CBD-focused medical products, so the national total depends on how a state defines legalization. Cannabis remains illegal under federal law in every state.

How many states have legalized medical cannabis?
The count sits at 38 states plus D.C. when a state must offer a patient registry, licensed dispensaries, and a defined list of qualifying conditions. Include limited low-THC programs and the number rises to 44 states. No state program overrides federal prohibition.

medical cannabis laws vs recreational
States with limited low-THC medical programs
Georgia, Indiana, Iowa, Tennessee, Texas, and Wisconsin allow only CBD-dominant or capped-THC products, often under 1% THC by weight. Some of these programs limit access to specific conditions such as intractable epilepsy. Patients in these states generally cannot buy flower or high-THC concentrates.
Which states have not legalized medical cannabis?
Idaho, Kansas, South Carolina, and Wyoming have no medical cannabis program of any kind. Nebraska voters approved a medical initiative in 2024, but a state court ruling invalidated it in 2025 and the appeal is still pending. Nebraska therefore has no operating patient program as of this writing.
What does a state medical cannabis program usually include?
- A registry of certified patients and a state-issued card
- A list of qualifying conditions set by the legislature or health department
- Possession limits measured in ounces or a 30-day supply
- Licensed dispensaries, cultivators, and testing labs
- Caregiver rules for minors and homebound patients
- Home cultivation limits in some states, and a ban in others
- Sales taxes, which medical patients often pay at a reduced rate
Are medical cannabis patients protected under federal law?
Cannabis is a Schedule I controlled substance under the federal Controlled Substances Act, so state legalization does not create federal protection. Since 2014, appropriations riders have barred the Justice Department from spending funds to prevent states from carrying out their own medical cannabis laws. Patients can still face federal consequences on federal land, at airports, and when crossing state lines with product.
Do you need a medical card to buy cannabis in an adult-use state?
No. In adult-use states, anyone 21 and older can buy from a licensed retailer without a medical card. A medical card usually lowers taxes, raises possession limits, and opens access to products that recreational rules restrict.
Do medical cannabis states recognize other states' cards?
No state is required to honor an out-of-state medical card, and most do not. A handful of states offer limited reciprocity for visitors, but the rules change often, so confirm with the state program before you travel.
Why do medical cannabis state counts differ between sources?
Counts vary because some trackers include low-THC programs, some exclude states whose programs have not launched, and some list D.C. separately from the 50 states. Alabama, Kentucky, and Mississippi have laws on the books with programs that have rolled out slowly. That means the list can shift within a single year.
