A
Alabama AL Alabama made smokable hemp a felony on July 1, 2025. Raw THCA flower is covered, and no licensed store sells flower in its place.
Alaska AK Alaska closed its hemp shelves to intoxicating products in 2023 and won in federal court in 2025. THCA-rich flower is still sold, by licensed marijuana retailers.
Arizona AZ Arizona's attorney general says intoxicating hemp belongs behind a dispensary counter. Smoke shops still dispute it. Here is what the opinion covers, and what it leaves open.
Arkansas AR Arkansas wrote its psychoactive-hemp ban in 2023, lost it to an injunction, and got it back from the 8th Circuit in June 2025. Here is what that means for THCA flower.
C
California CA California banned hemp flower on Jan. 1, 2026. Its dispensaries sell THCA-rich flower every day, as cannabis. The difference is the license, not the plant.
Colorado CO Colorado sorted cannabinoids into three tiers in 2023 and handed the intoxicating tier to its marijuana regulator. THCA flower lives on the licensed side.
Connecticut CT Connecticut has a name for THCA flower: a high-THC hemp product. The name comes with the full cannabis rulebook, and with it, the licensed counter.
D
Delaware DE Delaware's statute books point two ways on THCA flower, and the bill meant to settle it stopped in a Senate committee. The licensed lane, open since 2025, is the clear one.
District of Columbia DC In the District, the federal hemp label does not change what a product is. Regulators treat hemp-derived THC as cannabis, sellable only under a medical license.
F
Florida FL THCA flower is on shelves all over Florida. The state's own hemp rule says high-THCA flower fails the limit. Both things are true, and buyers should know the second one.
G
Georgia GA Georgia bans raw hemp flower at retail, lets compliant pre-rolls through, and since May 2026 caps every hemp product at 0.3 percent total THC.
H
Hawaii HI Hawaii does not run the THC math on hemp flower. It bans the format outright, at any potency, and now requires online sellers to register too.
I
Idaho ID Idaho writes THCA into its definition of hemp in plain words. Flower above 0.3 percent total THC is marijuana there, and the state has no licensed lane at all.
Illinois IL Illinois is one of the few states with its own Nov. 12 deadline. That day, a new Illinois Hemp Act counts THCA and ends smokable hemp sales, a month before federal law does.
Indiana IN Most national maps list Indiana as open. They skip a 2019 statute that criminalizes smokable hemp, which a federal appeals court left standing.
Iowa IA Iowa does not ask how much THCA is in the flower. It asks whether the hemp is meant to be inhaled, and if so, possessing it is a crime.
K
Kansas KS Kansas law lets hemp buds move only between licensed businesses. Selling them to a consumer, or rolling them into a hemp cigarette, is barred by statute.
Kentucky KY Kentucky grew hemp before most states did, and it never let raw buds go straight to consumers. The rule is short, specific and still in force.
L
Louisiana LA Louisiana once allowed floral hemp. Act 752 reversed that on Jan. 1, 2025, and wrote one of the tightest hemp-edible regimes in the South.
M
Maine ME Maine kept the delta-9 hemp test and built a 21+ category around it in 2025. That leaves THCA flower in a narrow, regulated hemp lane, until federal law closes it.
Maryland MD Maryland drew its hemp line at half a milligram per serving. Anything stronger, THCA flower included, belongs to licensed dispensaries.
Massachusetts MA Massachusetts rewrote its cannabis law in April 2026 and asked its regulator to study hemp by Dec. 15. Until then, the hemp lane has no rules of its own.
Michigan MI Michigan wrote THCA into its definition of THC in 2021. Since then, high-THCA flower is marihuana there, sold by licensees and nobody else.
Minnesota MN Minnesota legalized THC edibles from hemp in 2022 and adult-use cannabis in 2023. It never let high-THCA flower ride along as hemp.
Mississippi MS Mississippi's hemp statute never changed. Its attorney general's reading of the drug schedule did, and that reading closes the hemp shelf.
Missouri MO Missouri is the rare state where THCA flower is still sold openly as hemp, and the state with a fixed date to stop it. HB 2641 takes effect Nov. 12.
Montana MT Montana closed the hemp aisle in 2025 with one sentence of statute. Its licensed dispensaries still sell THCA-rich flower, as marijuana, to adults 21 and over.
N
Nebraska NE Nebraska's statute still reads delta-9 only, and the ban bill stalled again in April. The attorney general has not stopped pressing sellers, and Dec. 11 changes the federal ground.
Nevada NV Most THCA guides say a 2025 bill banned hemp flower in Nevada. The Legislature's records say otherwise. The real constraints are a county ordinance, a sign law and a pending state rule.
New Hampshire NH New Hampshire has already written THCA out of its hemp law; the ban starts Jan. 1, 2027. The federal change arrives three weeks earlier.
New Jersey NJ New Jersey adopted the federal total-THC test eight months early and ended the sell-through on April 13. THCA flower now moves only through licensed dispensaries.
New Mexico NM New Mexico measures hemp by total THC and caps most finished hemp products at 20 mg a package. High-THCA flower belongs to the licensed cannabis market there.
New York NY New York has measured hemp by total THC for years. Its CBD shops can sell hemp flower only below that line; high-THCA flower is a dispensary product.
North Carolina NC North Carolina is one of the few states where the hemp lane is still open under state law. A Senate-passed bill would close it, and the federal deadline lands Dec. 11 regardless.
North Dakota ND North Dakota wrote the total-THC formula into its hemp statute and steered every other cannabis product into its medical program. There is no adult-use lane.
O
Ohio OH Ohio wrote the federal hemp definition into its own code in March, eight months early. Court orders protect a handful of plaintiffs, not the market.
Oklahoma OK Many guides call Oklahoma open. The state's own hemp program administrator put it in writing in January: over 0.3 percent total THC, THCA counted, is not hemp.
Oregon OR When the OLCC bought hemp flower and sent it to a lab, every sample failed Oregon's total-THC limit. High-THCA flower belongs to the licensed market there.
P
Pennsylvania PA Pennsylvania's hemp lane is open under state law, but the bill that would close it is not dead. It came off the Senate table on Sept. 28.
R
Rhode Island RI Rhode Island's statute still says delta-9, but its regulator counts THCa. Since the Cannabis Control Commission took over hemp in 2025, high-THCA flower has no place on a hemp shelf.
S
South Carolina SC South Carolina's House killed the hemp regulation bill 28-69 in June. The state lane stays open until federal law closes it on Dec. 11.
South Dakota SD South Dakota's hemp law and its drug law use different words for the same 0.3 percent line. That one word, 'total,' is where THCA flower's status turns.
T
Tennessee TN Tennessee banned THCa flower and, separately, banned shipping any hemp-derived cannabinoid product to a consumer's door. Only face-to-face sales at licensed stores remain.
Texas TX Texas is the biggest THCA market to close. The DSHS rules counting THCA are enforceable while the industry appeals, and the federal date arrives Dec. 11 either way.
U
Utah UT Utah does not argue about THCA percentages for flower. It bans smokable hemp flower outright, and counts THCA in total THC for everything else.
V
Vermont VT Vermont's statute does the reclassifying itself: a hemp product over 0.3 percent total THC becomes a cannabis product. High-THCA flower belongs in licensed stores.
Virginia VA Virginia is the odd case: adults may possess cannabis, hemp THCA flower is out, and the licensed stores that would sell it do not open until July 1, 2027.
W
Washington WA Washington wrote one of the strictest lines in the country: any detectable THC in a consumable product makes it cannabis, and THCA is counted.
West Virginia WV West Virginia regulates hemp THC rather than banning it: permits, a 21+ rule, and a law that reaches out-of-state online sellers. How it treats THCA flower is less clear.
Wisconsin WI THCA flower is on Wisconsin shelves, and most guides call the state open. The statute's own testing words point the other way, and Dec. 11 settles it federally.
Wyoming WY Wyoming wrote the decarboxylation test into its definition of hemp in 2024. A federal appeals court upheld it. There is no licensed cannabis market to fall back on.
