A CBD store in Menomonee Falls was raided and three people were arrested after two small children had a nonfatal overdose after unintentionally ingesting a CBD-related product a parent bought from the store. The investigation into the overdose incident led to law enforcement executing a search warrant March 30 at Superstar Buds, N88-W16733 Main St., according to the news release from the Waukesha County Sheriff's Department. Authorities obtained evidence the business was selling products containing prohibited levels of delta-9 tetrahydrocannabinol or delta-9-THC, according to the news release. The Sheriff's Department said in the news release that state law allows for the sale of CBD-related products only if the delta-9-THC levels are not more than 0.3%. Several of the products obtained from the store during this investigation had delta-9-THC levels of more than 20%, the department said.
