Is THCA flower legal?

It is sold under the 2018 Farm Bill's definition of hemp, which draws the federal line at 0.3 percent delta-9 THC by dry weight and says nothing about THCA. Flower that tests under that delta-9 threshold as grown can be sold as hemp under that reading. But states are split on the question, the rules keep moving, and no shop can honestly promise you a settled answer.
The mechanics of the debate are simple. THCA converts to delta-9 THC when heated, so a flower that is compliant on paper and a flower that is not can be the same plant measured two different ways. States that test only delta-9 leave THCA flower on the market; states that have adopted a total THC standard (delta-9 plus a conversion factor for THCA) effectively take it off. Bills redrawing this line come up in state legislatures every session.
What you can check as a buyer is the paperwork. Legitimate THCA flower ships with a COA from a third-party lab showing the delta-9 result that makes it hemp under federal law, plus the THCA percentage itself. A product with no COA, or a COA from the seller's own lab, is not showing you anything.
Our line on it: we stock what is lawful to sell in Florida at the time we stock it, we keep the COAs where staff can pull them, and every THC sale is 21 and over with ID checked, no exceptions. If the law shifts, the shelf shifts with it. This is general information about how the category works, not legal advice; the current statute always outranks an article.
At Smoke Shop Kart, the thc shelf is stocked at all four of our Central Florida shops, in Orlando, Deltona and Kissimmee, open late every night. Find your shop, or , which is launching very soon.
