A 12-year-old student was hospitalized after using a vape pen that tested positive for narcotics, according to the McAllen Police Department.

One other student was detained in connection with the incident, police said in a news release. 

The 12-year-old was identified as a student from IDEA Quest. 

The incident occurred while the student was en route to school on a bus. Police officers responded to the 14000 block of North 29th Street on April 22 at around 7:34 a.m. after it was reported as a possible overdose.

According to a news release, the reporting party said the student was "unconscious, possibly inhaled something, and was vomiting."

Officers determined another student shared a vape device with the victim while on the school bus.

Upon using the vape device, the victim was seen acting in an "abnormal" manner, according to the news release. After arriving at the school, the victim was left on the bus experiencing an abnormal reaction.

Police said the vape device tested positive for 50% Benzylpiperazine, "a controlled substance that has been promoted as a substitute for meth."
