Julio César Sánchez said his daughter, a ninth grader, told him that she knew of two students who had been affected after taking a “prohibited substance,” but that school authorities had not yet informed parents what it was.
The incident came one day after three students at another middle school near the northern city of Monterrey were treated for doses of clonazepam, a tranquilizer or sedative sometimes sold under the brand name Klonopin.
Daniel Carrillo, the mayor of the Monterrey suburb of San Nicolás de los Garza, confirmed the incident. In his Twitter account, Carrillo wrote that “the first thing tomorrow they (the students) will continue under observation,” and said he gave thanks “it wasn’t any worse.”
The pills play a role in a social media trend known as the “clonazepam challenge,” in which students compete to be “the last person to fall asleep.” The pills can cause extreme drowsiness.
Sánchez said there had been talk about social media challenges at his daughter’s school.
“Unfortunately, these things can lead kids to extremes,” Sánchez said. “The freedom on social media can can lead to good, or bad.”
