Yes.

The 2026 U.S. Farm Bill reclassifies the definition of intoxicating hemp and is expected to lead to the closure of businesses selling delta-9 THC and hemp-derived products as soon as November.
The new rule bans the sale of products that have more than 0.4 milligrams of THC per container, excluding virtually all such products.
Currently, Wisconsin hemp dispensaries can sell products with up to 0.3% of delta-9 THC by weight, under a loophole in the 2018 Farm Bill. Current law doesn’t have any restrictions on hemp-derived products, such as delta-8, THCP or delta-10. The 0.4 milligram limit is far stricter.
The new rule goes into effect Nov. 12, 2026.
According to Wisconsin Gov. Tony Evers, the hemp industry closure could impact 3,500 jobs and reduce economic input by $700 million. Wisconsin has 470 federally licensed hemp growers.
