Four teens from Council Rock High School in Newton, Penn. have been hospitalized for possible overdoses on Monday after ingesting pills known as Snurf.

If you’re wondering what Snurf pills are, well, officials from the Council Rock School District already have the answer for you. “From the information on the packaging, we understand that Snurf is an herbal supplement with mood altering properties.” They further urged everyone having this kind of pills to “dispose of them immediately.”

Moreover, the Council Rock District Superintendent, Mark J. Klein said officials went on with their search and found out that Snurf pills are widely available on the Internet through herbal dealers. The pills consist of pure dextromethophan, a.k.a DXM, a substance present in many cough syrups, which can become a hallucinogen if taken in large doses. These pills seem to make their users violently ill, though not in a life-threatening way. However, they can cause memory loss, depression, anxiety, detachment from self, sense of unreality, blurred sense of identity seen with ketamine a very dangerous drug.

The 10th-grade boys were transported to St. Mary’s Hospital by ambulance after a resource officer at the high school saw their state was altered.

“To the best of my knowledge they were simply sick, sick to the stomach. They were not in an altered-state-of-mind kind of situation,” Klein said.

By Monday night, three of the teens had been transferred to the Children’s Hospital of Philadelphia. The fourth had been released.

Police is currently investigating the case saying that charges may be filed based on the outcome of the investigation. The names of the students have not been released.
