Is THCA Legal in Wyoming?

Wyoming added naturally occurring THC to Schedule I. The controlling authority is SF 32 / Enrolled Act 24 (2024), effective July 1, 2024, and the measurement standard Wyoming applies is post-decarboxylation testing, with no synthetic substances permitted.

That standard decides everything. Where a state measures total THC, delta-9 plus 87.7% of the THCA content, high-THCA material fails on the same lab result that passes federally. Run any Certificate of Analysis through the total THC calculator to see both numbers.

What Happened in Wyoming

Litigation resolved against the industry: a preliminary injunction was denied and the case dismissed in Green Room LLC v. Wyoming in August 2024, and the Tenth Circuit affirmed in October 2025, holding the state ban is not preempted by federal law.

What This Means for Buyers in Wyoming

Nothing with meaningful THCA content.

Wyoming THCA Questions

Why is THCA not permitted in Wyoming?

Because Wyoming measures post-decarboxylation testing, with no synthetic substances permitted rather than delta-9 alone, under SF 32 / Enrolled Act 24 (2024), effective July 1, 2024. High-THCA material fails that test by definition.

Is any hemp product still legal in Wyoming?

Nothing with meaningful THCA content.

Does federal legality override this?

No. Federal law is a floor, not a ceiling — appellate courts have repeatedly upheld stricter state standards.
