KEARNEY, Neb. - Nebraska's Attorney General is expanding his crackdown on unlawful THC products.

Attorney General Mike Hilgers announced Thursday via news release that his office has sent cease-and-desist letters to all of the remaining locations in Grand Island and Kearney that have not already been sued.

The action follows a multi-agency investigation that the attorney general's office says revealed several stores that selling THC-containing products that were mislabeled and in violation of state law.

"The Grand Island Police Department, Kearney Police Department and Nebraska Attorney General’s Office investigators made purchases of products from multiple stores located in Grand Island and Kearney, where over 95% of the products purchased had labels that incorrectly identified the content of the products, and many products appeared to be marijuana marketed as hemp," the news release states. 

The letters sent to these stores say that many of the THC-containing products their companies sell misrepresent the concentrations and types of THC contained within the products.

These letters come two weeks after the Attorney General sent similar letters to Omaha-area stores, and after the office sued all of the stores in Norfolk.

“We are grateful to our partner agencies for their help in our investigation and enforcement efforts,” said Hilgers, “We will continue to escalate our city-by-city efforts until this problem is solved.”

The Attorney General’s Office is demanding that each store return a signed document indicating their Assurance of Voluntary Compliance. If they do not return a signed settlement, then the office will initiate litigation and will seek penalties and fees to the fullest extent allowed by law.
