After the school nurse became concerned about the "severity" of their illness, first responders were called to the school, Key Elementary's assistant principal Jennifer Green said in a letter to families obtained by multiple news outlets.

"The families of all students involved in this incident were immediately contacted, and five students were transported to the hospital for continued monitoring," Green wrote, adding that "all health and safety protocols have been followed."

She continued, "As we work with the DC Public Schools Student Supports Division and our school-based mental health team to hold age-appropriate conversations around substance use awareness and prevention with our 5th-grade students, we will also be prioritizing restorative practice in relation to this incident."
