RAPID CITY, S.D. – You often hear about compliance checks for underage alcohol sales, but how about for ‘diet weed?’ The Rapid City Police Department and Pennington County Sheriff’s Office recently completed compliance checks at several local smoke shops and convenience stores for the chemically modified cannabinoids, which lawmakers made illegal during South Dakota’s 2024 legislative session.

“These products are widely accessible, and it’s important products are not only safe for consumption, but legal for use under state law,” said Rapid City Police Chief Don Hedrick.

According to the South Dakota Department of Health, which supported the legislative ban, naturally occurring CBD from hemp can be chemically modified to create these potentially dangerous substances in massive quantities. Unlike the natural plant which produces very small amounts of Delta-8, 9 or 10 THC, “diet weed” is created using a chemical reaction often in an unregulated lab, which may be contaminated with the harmful chemicals used to make them. 

“These substances, often found in the form of gummies, suckers, vape cartridges, oils, and beverages, can have potent psychoactive effects similar to marijuana,” the Pennington County Sheriff’s Office said in a statement.

On June 10, authorities sent letters to Pennington County businesses advising them of the updated law and warning of future enforcement. Following that notice, officers and deputies purchased a range of products for forensic testing to determine whether they complied with state regulations.

Authorities say their focus is not only on enforcement but also on education and ensuring businesses are aware of the law.

“We want to better understand what’s being sold in our community and ensure that both consumers and retailers are informed,” said State’s Attorney Lara Roetzel.

Businesses found knowingly selling non-compliant products may face penalties, including a Class 2 misdemeanor for each violation.

“It’s incumbent on those selling these products to know what is legal and what is illegal,” said Pennington County Sheriff Brian Mueller. “We will continue this process of checking business establishments until we have the confidence that what is being sold is legal and safe for customers.”
