Legal Today, Illegal Tomorrow? Wisconsin’s Hemp Shops Face A Federal Crackdown
With marijuana still banned in the state, hemp-derived THC and CBD products are the latest target of Washington policy shifts.

Wisconsin Hemp Flower owner Luke Heidt has been growing hemp on an old dairy farm outside Eau Claire since the state legalized the crop in 2017.
Now, like many hemp farmers across Wisconsin, Heidt is planting less as he prepares to go out of business this November. That’s when a federal law changing the legal definition of hemp goes into effect.
He says he’s “terrified” and “sad” for the future of Wisconsin’s bustling hemp industry, calling it a “100 percent disaster for hemp farmers” across the nation.
Recreational and medicinal marijuana are both illegal in Wisconsin. But, stores selling THC and CBD products, and the farms distributing them, have been working under a federal loophole. It allows the sale of these products as long as they are hemp-derived and contain no more than 0.3 percent of delta-9 THC.
The new federal legislation ends this by banning all hemp products with a total THC concentration over 0.3 percent.
In a letter sent to Congress on Feb. 27, Gov. Tony Evers said the change will cut $700 million in production and 3,500 jobs from the state’s economy.
Wisconsin currently has 274 licensed hemp growers, according to the U.S. Department of Agriculture. Last November, that number was 470.
Heidt calls himself an “old-school CBD farmer,” meaning his business focuses on hemp without tetrahydrocannabinolic, or THC, the intoxicating chemical in marijuana, and its variants, THC-A and delta-9 THC. But he worries that because his products are so close to the new legal limit, his customers will not want to take the risk by buying.
“Almost everything I produce will be so close to the line of being illegal that I’ll be too close to the line to do it,” Heidt said. “What if I get 0.31? Am I going to get a felony and get locked up?”
It’s a question going through some minds of those in Wisconsin’s hemp industry.

Chris Busky owns Wonders of Nature, a cannabis cafe and dispensary in Eau Claire. He works with small hemp farmers around the area. He says many are sitting “in a state of limbo.”
“A lot of these farmers are sitting on crops that they grew last year (and) it’s going to be difficult for them to sell,” Busky said. “Because by the time you get that material processed into a finished good we’re going to have the November deadline up.”
Working behind the counter, Busky said he’s seen his customers improve their quality of life by taking his products.
“From your 80-year-old grandma that hasn’t slept in 20 years (and) is now using a five milligram sleep gummy and is sleeping like a baby … to somebody that just came in with stage four pancreatic cancer and is scared and not sure how to handle their anxiety and stress, and it’s keeping them up at night,” Busky said.
He said he fears that THC consumers benefiting from the products might turn to buying illegally when November comes.
