Topic hub

Legality & the Federal Clock

Two questions decide everything here: what does your state test for, and what happens on December 11, 2026. States that measure Δ9 alone have permitted THCA flower; states that measure total THC have not — and the federal ban on intoxicating hemp supersedes all of it when it takes effect. This hub holds the statute-cited state checker, the ban explainer, and the discipline the topic deserves: citations, last-checked dates, and gray called gray. Decision support, not legal advice.
