Is Cannabis Legal in [State]? How to Check the Rules Where You Live
Cannabis is legal for adults in 24 states, medical in most others, and banned in a few. Here is how to check the rules where you live.
No, CBD is not legal in all states on the same terms. Hemp-derived CBD that contains no more than 0.3% delta-9 THC by dry weight is legal under federal law, but each state sets its own rules for what can be sold, who can buy it, and where it can be purchased. That means a CBD product fully legal in one state can be age-gated, restricted to dispensaries, or banned in another.
The Federal Rule on CBD
Congress removed hemp from the federal definition of marijuana in the 2018 Farm Bill, so hemp and hemp-derived CBD are no longer controlled substances under the Controlled Substances Act. The legality test is not the CBD itself. It is the delta-9 THC concentration: 0.3% or less on a dry weight basis keeps a product in the hemp category.
Federal permission is not the same as federal approval for every use. The FDA has not approved CBD as a food ingredient or dietary supplement and has only approved a purified CBD drug for specific seizure disorders. The agency has said adding CBD to food or supplements sold across state lines is not allowed, while enforcement has mostly targeted products making disease claims.
Why States Still Differ
States keep authority over health, safety, and commerce inside their borders. A state can be more restrictive than federal law, and many are. States also inherit federal ambiguity, which is why you see open retail shelves in one state and dispensary-only access in the next.
The Main State Approaches
- Permissive: Hemp CBD sold in grocery, smoke shops, and online, usually with age limits of 18 or 21.
- Regulated: Hemp CBD allowed but with state licensing, testing, labeling, and lab report requirements.
- Restricted channel: CBD available only through state-licensed medical or adult-use cannabis dispensaries.
- Tightly limited: Only zero-THC or THC-free CBD products permitted, or bans on smokable hemp flower and inhalable forms.
- Specific cannabinoid bans: Some states have blocked hemp-derived delta-8 THC and similar compounds even though hemp remains legal.
Where THC Products Fit
Delta-9 THC above 0.3% is still federally illegal and remains a Schedule I substance. It is legal for adults only in states with adult-use cannabis programs, medical-only in others, and prohibited in the rest. Online cannabis sales are legitimate only where a state licenses them and a licensed operator handles delivery. Hemp-derived compounds like delta-8 and THCA sit in a patchwork where state legislatures keep changing the rules.
How to Check Your Own State
- Start with your state department of agriculture or health and look for a hemp program page.
- Check the state cannabis regulator for rules on THC and hemp-derived cannabinoids.
- Read the product label and lab report for delta-9 THC content per serving.
- Confirm age limits and whether in-store, delivery, or shipping is allowed.
- Check county and city ordinances, since local bans exist inside legal states.
Common Questions
Is CBD legal in all 50 states if it has no THC?
Most states allow THC-free CBD, but a small number apply strict zero-tolerance testing or channel restrictions, so verify before ordering.
Can I buy CBD online and ship it anywhere?
Shipping hemp CBD is generally treated as legal at the federal level, but destination-state law and the retailer's own compliance rules decide whether an order is fulfilled.
Does a hemp license in one state cover me in another?
No. Licenses work inside the state that issues them, and carrying THC products across state lines creates federal exposure regardless of local legality.
