Wisconsin	Legal	No	Hemp products in Wisconsin must be derived from industrial hemp grown under a state-issued license and contain no more than 0.3% delta-9 THC by dry weight. The Wisconsin Legislative Council suggests that synthetically produced Delta-8 THC is illegal, potentially extending to Delta-9 THC. However, state law does not explicitly clarify the legal status of synthetic cannabinoids, leading to ambiguity.
Wyoming	Legal	No	Individuals can freely buy hemp-derived products with less than 0.3% THC.

The legality of Delta 9 THC for recreational and/or medicinal purposes varies by state.
Delta 9 THC is legal to use in any state that has legalized recreational marijuana. Some states have included Delta 9 in their medicinal marijuana legalizations as well.

In 2024, the legal status of Delta 9 THC in the United States remains dynamic, with laws subject to frequent revision. While states like Arizona, California, and Colorado have legalized its use, among others, a significant number including Alabama, Alaska, and Arkansas maintain strict prohibition. This evolving legal landscape reflects ongoing debates over Delta 9 THC regulation, with states continually reassessing their positions. Currently, Delta 9 THC is legal in 18 states, while it is prohibited in 32 others.
