PRESTONSBURG, Ky. (FOX 56) — A string of overdose-like symptoms among Prestonsburg High School students led to a troubling discovery from an area tobacco store.

According to the Prestonsburg Police Department, authorities received numerous calls about students displaying overdose-like symptoms requiring medical attention. The police said there were five incidents in one week.

Investigators said each student had been using electronic vapes and other products despite being minors.

Police worked with minors, with parental consent, to conduct controlled purchases from area stores, including Quick Stop Smoke Shop Discount Tobacco and Vaping. The store, located within 1,000 feet of the high school, reportedly sold vapes to minors while under police surveillance.

Police sent the products off for lab testing, where results showed none of the products were accurately labeled. Some contained what the police called “rogue” products that contained levels of more than 90% active impairing ingredients, which is believed to have caused the students’ overdoses.

After consulting with the FDA, the police obtained a search warrant and seized a large quantity of the mislabeled, misbranded, and questionable products that were causing child overdoses.

In a Thursday release, the Prestonsburg Police Department said, “We remain committed to the wellbeing of our community and especially our children. If you suspect illegal or dangerous activity, call us at 606-886-1010. You can remain anonymous.”
